| Mobile Phone Wap Technology |
WAP or wireless
Application Protocol, adds a new dimension to the Internet i.e.
mobility. With a mobile phone or a laptop that supports WAP you can
book tickets, order food and check your bank account at any time. You
can play games while stuck in traffic, get the stock market news in
the elevator… complete mobility, the world wide web with you all the
time. It also includes services such as downloading entire phone books
and new, improved ways of controlling outgoing and incoming calls will
make mobile telephony even easier. To access WAP services you need a
WAP product. Besides the WAP compatibility, WAP products have a large
full graphic display and include a micro browser. The basic function
of WAP is for mobile phones to be able to communicate with a server
installed in the mobile phone network. It brings together the web and
telecommunications. Of course, as all new technologies, WAP also comes
with its questions and hesitations.
|
|
HISTORY AND BRIEF TECHNOLOGICAL OVERVIEW |
This technology is only
a couple of years old. Brought in by a company called "Unwired
Planet", a combination of the leading telecommunications companies.
HOW THE SYSTEM WORKS:
-
Make a request in
WML (Wireless Markup Language), a language derived from HTML
especially for wireless network characteristics.
-
This request is
passed to a WAP Gateway that then retrieves the information from
an Internet server either in standard HTML format or preferably
directly prepared for wireless terminals using WML.
- The requested information is then
sent from the WAP Gateway to the WAP client, using whatever mobile
network bearer service is available and most appropriate.

FREQUENTLY ASKED QUESTIONS |
Which content
is possible to access with WAP?
Almost anything available on the net; weather, news, stock market
information, product updates, software downloads and so on. There is
also a broad spectrum of other possible applications: e-mail,
information search and retrieval, e-Commerce, calendar and office
applications, maps and position-based services, voice messaging and
communication, call control, Intranet/Internet access, among others.
What type of devices will use WAP?
Handheld digital wireless devices such as mobile phones, pagers,
two-way radios, smart phones and communicators from low-end to
high-end.
Is WAP suitable for multimedia mobile
services?
A current area of interest within WAP Forum is evolution to support
multimedia mobile services. WAP is an open protocol that allows the
transport of many forms of multimedia content. However, some
multimedia services, especially those based on streaming media,
require further enhancements to WAP.
What are the properties of WAP?
WAP can only support DOS-like 2D graphics which are shown on the
screen of the WAP devices. The current downloading speed of WAP is
between 9.6kbps to 14.4kbps, depending on the telecommunication
network it is riding on.
What is a WAP gateway?
The WAP gateway/proxy connects the wireless world with
Internet/Intranet, providing a path from the WAP-enabled handsets in
the wireless world to applications on the Internet/Intranet. In
addition to being a bridge between the Internet world and the mobile
world, the WAP gateway/proxy offers service logic such as:
a) End-user authentication
b) Encoding of WML pages
c) WML script compiling
Can WAP connect me to any site that I want
to?
As long as the site has been "wapified", that is, the site has been
written in WML (wireless markup language) that is accessible by WAP
devices.
Is surfing the Internet on a WAP device
similar to surfing on a PC?
Pretty similar. The main difference is that WAP does not support
fanciful graphics as WAP is written in WML . WAP supports real time
text information and simple DOS-like graphics.
What is the difference between WAP and SMS?
With ordinary SMS one can send text messages to mobile phones, e.g.
receiving today's news or sports results. But SMS can only give the
mobile phone user a limited degree of interaction. One can compare SMS
with email: one can send and receive messages but it is not really
possible to take any action or easily navigate to other information.
WAP could be compared with an Internet browser: it supports hyperlinks
for easy navigation and forms that are easy to fill in with selected
data and receive a response. In conclusion, the difference between WAP
and SMS could be compared to the difference between an Internet
browser and Email.
What is the difference between WAP and SIM?
One can create custom-built applications with SIM Application Toolkit
(ATK) that runs on the SIM card in the mobile phone. A SIM card is the
Smart card that identifies the user and where the user's phonebook is
located. With SIM ATK one can set up new menus, show text in the
display, get access to the phonebook and send / receive SMS messages.
The difference between WAP and SIM ATK is that SIM ATK applications
are located in the phone on the SIM card, and to update an application
one has to exchange the SIM cards of all the users. WAP applications
on the other hand are fetched from a web-server and can be updated at
one central location. Smart cards will have a role to play in the
fuure in WAP security and user/operator personalization.

DISADVANTAGES OF WAP |
- Expensive.
- Did not have a packet-based
service for long time.
- Limited size of RAM and ROM.
- Limited power supply.
- Low bandwidth.
- Difficult to keep the phones
up-to-date with new WAP services.

Mobile phone talk plan mobile phone tips and tricks
| Mobile Phone Talk Plan |
So, now that you have bought a new cell phone,
you must be wondering what talk plan to choose? With all companies
pitching in to woo you, it is important to choose only once you have
identified your needs and pocket.
Your calling plan will decide the minimum amount you will have to pay
to the service provider in a month. It's like an agreement that you
make to use your phone for certain amount of time each month. Keep in
mind the options available to you before choosing a talk plan.
|
|
TECHNOLOGY |
In India, we use the
digital network specified as GSM 900 (Global Systems for Mobile
communications). The digital standard, including CDMA, TDMA and
GSM platforms, allows for more callers to at the same time, occupy
space on each of a service provider's cells, making it the superior
choice for highly populated or metropolitan areas. Disadvantages to
digital systems are their lack of unified technology and a small,
metropolitan-focused calling area.
|
|
|
SERVICE AREA |
Ask yourself. Do you
want a cellular phone for emergency use? Will you be using your
phone/service around town? Travel a lot? Planning a coast-to-coast?
Whether local, National or International you'll want to choose a
calling plan that encompasses the physical boundaries of your calling
needs. While using your cell phone on an occasional trip away from
home may add extra roaming or long-distance fees to your bill.
National plans, are more expensive than local plans,but will give you
the freedom to call regardless of your geographical location.
|
|
|
CALLING PLAN OPTIONS |
Caller ID, three-way
calling, voice-mail, numeric paging, call forwarding and Internet
access are just some of the great options offered to calling plan
subscribers.
- Use the
night-time advantage:
Service providers often give away bundles of night time and
weekend minutes for mere sums of money, maximizing your talk time
value. 9 to 9 landline charges, low call charges, cheaper sms etc.
are some of the cool features available.
-
Know your home coverage area:
This is very important, if you don't want to be presented with a
bill showing astronomical roaming charges. If you know you are out
of the service area at any point then limit your calls to only the
most essential.
-
Understand all the features of your plan: Familiarize
yourself with all the features included in your plan and make sure
you know what you're getting in exchange for extra fees.

SIM CARDS-the key to mobile communications |
Subscriber Identity
Module, or a SIM card is the key to European and Asian mobile
communications, the digital equivalent of an ID card. All the
information about the service you subscribe to, your plan details,
your phone number, etc. are stored in this thin, credit card-like
unit. It's placed in the handset to activate the phone and your
service.
A SIM card contains integrated chips that extend its intelligence and
capabilities by leaps and bounds. Apart from being able to store your
entire phone directory, this smart card provides access to a whole
range of applications such as short message service, mobile banking,
and even the mobile Internet. Your phone becomes personalised and
user-friendly.
The big advantage from a user's point of view is the great flexibility
of SIM cards. When traveling, you don't need to carry your phone, just
take the card. Rent a phone from the airport once you arrive, slip the
card in the phone and you are again connected to the world, with the
same phone number.
Each card has an authentication code, a password or a PIN, specific to
your service provider, which ensures that only you are using the card.
GSM's encryption technology is fairly advanced and is considered to be
one of the most secure technologies in mobile communications.
PIN / PUK
The SIM Card has a security feature called the PIN / PUK- a four-digit
number. You can change this number to any four-digit number of your
choice using the handset. Once set, three wrong attempts of entering
the PIN / PUK can get the SIM card blocked temporarily. It now
requires the Master PIN / PUK number to unblock the SIM. Generally ten
wrong attempts to enter the PUK number can get the SIM card blocked
permanently and it will require a SIM exchange.
|
|
|
SIM CARD CARE |
The SIM Card
can be permanently damaged, if
- It is frequently or roughly
inserted or removed.
- The wrong side is inserted or
removed.
- It is bent or twisted.
- It is scratched or written upon.
- Anything is stuck on it.
- It is exposed to extreme
temperatures or magnetic fields.
Your SIM Card can be used with any compatible GSM 900 MHz phone.

TIPS FOR CHOOSING YOUR MOBILE PLAN |
Costs of the mobile service plan Read the
fine print.
There are a lot of hidden costs involved like activation fees,
contract termination penalty, monthly service charges for particular
features etc. Make sure you know all the hidden charges and penalties
for any plan you subscribe to. Analyse short-term benefits and overall
plan structures to see if they are worthwhile in the long run and suit
your calling habits.
How are you charged?
1. You are charged airtime whether you call or receive a call. 2. Many
plans round up to the next minute. If your call is 61 seconds, you're
charged for two minutes.
Monthly operational charge
In general, the monthly cost for mobile phone service increases based
on the amount of airtime you use your phone for. A very low initial
payment may be linked to higher monthly charges, while a higher
initial price package, may result in lower monthly charges.
So buy your talk plan accordingly, make sure you get full value for
your money

Mobile Phone New Technology mobile phone tips
Mobile Phone New Technology MMS- MORE THAN JUST TALK This is the age of Multimedia Messaging Service. MMS is in; a versatile feature that allows users to send colour pictures, photographs, voice clips, programs, videos and ofcourse text from their cell phones. The rates are a little higher as compared to SMS, but MMS opens up a whole new world of communication at your finger tips. All you need is an MMS-enabled phone and a subscription to a service provider that supports MMS. With MMS, you can, not only send your messages from one phone to another, but also from phone to email, and vice versa. You can send, store and edit picture messages. There are a number of sites online that let you download pictures free of charge. Some MMS phones even come with an inbuilt camera, so a person can click pictures spontaneously and send them across to another MMS cell phone user. But with phones that do not have an in-built camera, these pictures have to be obtained from the Internet. The messages sent and received are either in text or graphics, once again depending on the phone model. With MMS, you can even download MP3 music, games and video clips on your phone! The following networks offer MMS: BPL (Mumbai) - MMS and GPRS only for post-paid users at Rs. 199 per month with 100 MMS free. If you exceed the 100 limit, MMS are charged at Rs. 3. Hutch- Rs. 99 per month. Prepaid users have to also pay Rs.50 as the initial activation charge. Messages can be downloaded from the Hutch site at Rs. 8 per MMS. Sending MMS is free. Airtel- Offers free MMS service. To activate, you need to send an sms to 222 from your MMS enabled phone. Spice (Bangalore) - Rs. 99 per month. 25 outgoing messages free, after which there will be charge of Rs.5 per MMS. Idea- Offers downloading of video messages from their site. Also allows sending and receiving pictures and music. SMART PHONES- (PDA PHONES) One step further are PDA-enabled phones, more commonly known as smart phones. These have a Digital Organiser, Excel, Word and Internet capabilities- all in one phone. Some even have an integrated camera and a MP3 player. These phones have large screens and allow you to write into it (after you learn the easy technique). They also have voice recognition capabilities. These features make the phone bulkier and costlier but then these gizmos sure do separate the men from the boys. E-MOBILE...REDIFINING TECHNOLOGY GPRS AND WAP GPRS and WAP let you enjoy a continuous wireless connection to data networks (Internet) and access favorite web sites, entertainment services and other web applications. With WAP, GPRS, you can go online on your cell phone. All you need is a GPRS/WAP enabled phone and activation from the service provider. Call up the Customer Care number and ask them to activate the service, afterwhich you need to download the GPRS settings as instructed and GPRS is activated. Airtel charges Rs. 600 per month for GPRS and airtime. MMS, however is free. Reliance India charges Rs. 200 + usage charges Rs, 40 paise per minute, whereas Hutch charges Rs. 99 for GPRS + airtime. Using your cell phone as a modem: Alternatively, you can connect to the Internet using your cell phone as a modem. For this your cell phone should support HSCSD. If your phone supports HSCSD, you can connect to a laptop, desktop or a PDA, using infrared, data cable or Bluetooth and then dial your ISP connection. This method is useful if you want to check some urgent mails or access a site when on the go. The connectivity is slow and also is expensive as compared to a normal Internet connection using a modem. You pay the ISP for the Internet hours and the cell phone service provider for the airtime charges. With Internet connectivity, you can download a variety of groovy ringtones, logos, and graphics to jazz up your phone. If you are tired of the monophonic tones, polyphonic ringtones is the latest craze. All phones do not support poplyphonic ringtones, especially the old models. If your phone does, you can download a range of polyphonic ringtones from the Internet. What's more, you can even acquire information about current news, movies, stock markets, weather, forecasts, jokes etc. All this is just a click away from your phone and all for a nominal fee. Checking email, acquiring information about current news, movies, stock markets, weather etc. is just a click away from your mobile phone. Games: With the advent of GPRS and Java-enabled phones, gaming is no longer limited to basic games like Snake and Space Impact. The GSM as well as the CDMA subscriber base is growing at a good rate and with Reliance offering Java support on its CDMA phones, the basic cell phone has turned into a pocket-PC! So, what do you need to play games on your cell phone? 1) Lots of in-built memory 2) GPRS or Java enabled phones and 3) Colour screen (optional) How can you get games on your cell phones? You can get games either from your cell phone service provider such as Hutch (Orange), BPL, Reliance by downloading them from the internet using WAP or GPRS or you could get them uploaded onto your cell phone at a manufacturer's showroom. (e.g Nokia) HUTCH (ORANGE) For downloading games using Hutch (Orange), it is necessary to have GPRS enabled on your cell phone. This can be activated through Hutch (Orange) by paying Rs. 99 if you are a postpaid user. Prepaid users can activate GPRS by paying Rs. 99 as activation fees + Rs.99 every month. Both pre-paid as well as post-paid users can download the games from the Hutch (Orange) site by paying Rs.20 per game for 20 rounds. For Rs. 50 you can play the game as many times you want, plus you get a free Photo Messaging facility. You need to check if Hutch supports gaming on your cell phone model though. BPL For downloading games using BPL website, you need to have either MMS or GPRS enabled on your phone. If not, you can go to a BPL showroom and get the games uploaded onto the phone. The charges are the same as that of Hutch, Rs. 20 per game for 20 rounds and Rs.50 for an unlimited usage, except that you'd have to shell in an extra Rs. 25 as service charges if you get the games uploaded at the showroom. RELIANCE (CDMA) Reliance Infocomm in India allows users to download games on their Java-enabled cell phones using their 'R-World service'. With R-World, you can access and download from a huge variety of Java games such as Arcade, Boards, Puzzles, Cards, Sports, Casino, etc free of charge till March 2004. NOKIA Nokia is offering its own games to the Nokia cell phone users through cell phone service providers such as Hutch (Orange), Airtel, BPL etc. As of now, only Hutch and Orange subscribers can access the WAP-based content, whereas the Airtel, RPG (Chennai) and BPL Mobile customers can access only the SMS-based content. You are charged Rs. 49.9 per games apart from the GPRS activation and rentals. You can download from a variety of games such as Pooltime, Crashn'burn, AlphaWing etc at www.nokia.co.in. This facility is available only on a few Nokia phones at present. These striking features in mobile phones have changed consumer behavior and their attitudes towards demands. They want better than the best, and thanks to sophisticated expertise they get it too. Large amount of functions and significant advantages have made cellulars a boon in disguise. Steady usage of this wire free wonder has life always on the move. At no point of time can work come to an absolute stand still. Impeccably, the credit goes to its advanced features and service providers, due to which this network functions smoothly. At the end of the discussion, one thing is evident ' A mobile in your hand…has the world at your finger tips'! Labels: mobile phone tips
Mobile Phone GPRS Information , mobile phone tips
Mobile Phone GPRS Information THE GPRS The General Packet Radio Service (GPRS) is a new non-voice value added service that allows information to be sent and received across a mobile telephone network. It supplements today's Circuit Switched Data and Short Message Service. It is a step ahead to provide a massive boost to mobile data usage and usefulness. Payments are made as per data volume, instead of per minute pulse rate. You need to pay a fixed rent around Rs. 750 per month, after which you can surf for unlimited hours. Except for one thing, as a developing technology, the net connection is a slow process. BENEFITS Surfing the net; emailing; all through the mobile. Fast transmission of text documents, spreadsheets, photographs and illustrations; mobile chatting and on-line games. A round the clock net connection, even when you are on the move. FEATURES SPEED A GPRS can achieve speeds up to 171.2 kilobits per second (kbps) using all eight timeslots at the same time. This is thrice as fast as current data transmission systems. IMMEDIACY GPRS facilitates instant connections whereby information can be sent or received immediately as the need arises, subject to radio coverage. No dial-up modem connection is necessary. NEW APPLICATIONS, BETTER APPLICATIONS GPRS facilitates several new applications that have not previously been available over GSM networks due to the limitations in speed of Circuit Switched Data (9.6 kbps) and message length of the Short Message Service (160 characters). GPRS will fully enable the Internet applications you are used to on your desktop from web browsing to chat over the mobile network. WHAT DO YOU NEED FOR A GPRS ? To begin with, a mobile phone or terminal that supports GPRS. A subscription to a mobile telephone network that supports GPRS. § Knowledge of how to send and/ or receive GPRS information using their specific model of mobile phone, including software and hardware configuration. A destination to send or receive information through GPRS. Whereas with SMS this was often another mobile phone, in the case of GPRS, it is likely to be an Internet address, since GPRS is designed to make the Internet fully available to mobile users for the first time. KEY NETWORK FEATURES OF GPRS PACKET SWITCHING GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. This gives the user an option to use a packet-based data service. With GPRS, the information is split into separate but related "packets" before being transmitted and reassembled at the receiving end. SPECTRUM EFFICIENCY Efficient use of scarce radio resources means that large numbers of GPRS users can potentially share the same bandwidth and be served from a single cell. The actual number of users supported depends on the application being used and how much data is being transferred. Because of the spectrum efficiency of GPRS, there is less need to build in idle capacity that is only used in peak hours. GPRS therefore lets network operators maximise the use of their network resources in a dynamic and flexible way, along with user access to resources and revenues. INTERNET AWARE GPRS fully enables Mobile Internet functionality by allowing inter-working between the existing Internet and the new GPRS network. LIMITATIONS OF GPRS LIMITED CELL CAPACITY FOR ALL USERS There are only limited radio resources that can be deployed for different uses- use for one purpose precludes simultaneous use for another. For example, voice and GPRS calls both use the same network resources. The extent of the impact depends upon the number of timeslots, if any, that are reserved for exclusive use of GPRS. SPEEDS MUCH LOWER IN REALITY Achieving the theoretical maximum GPRS data transmission speed of 171.2 kbps would require a single user taking over all eight timeslots without any error protection. Additionally, the initial GPRS terminals are expected to be severely limited- supporting only one, two or three timeslots. The bandwidth available to a GPRS user will therefore be severely limited. APPLICATIONS OF GPRS A wide range of corporate and consumer applications are enabled by nonvoice mobile services such as SMS and GPRS. CHAT Because of its synergy with the Internet, GPRS would allow mobile users to participate fully in existing Internet chat groups rather than needing to set up their own groups that are dedicated to mobile users. Since the number of participants is an important factor determining the value of participation in the newsgroup, the use of GPRS here would be advantageous. TEXTUAL AND VISUAL INFORMATION You can receive information, which is in the form of not only text, but maps, graphs or other visuals. STILL IMAGES Still images such as photographs, pictures, postcards, greeting cards and presentations, static web pages can be sent and received over the mobile network as they are across fixed telephone networks. It will be possible with GPRS to post images from a digital camera connected to a GPRS radio device directly to an Internet site, allowing near real-time desktop publishing. MOVING IMAGES You will also be able to receive moving images and receive transmission from anywhere. WEB BROWSING You will also be able to use the GPRS for browsing the net. DOCUMENT SHARING/ COLLABORATIVE WORKING Mobile data facilitates document sharing and remote collaborative working. This lets different people in different places work on the same document at the same time. AUDIO Dictating to a mobile phone, would simply not give sufficient voice quality to allow transmission to be broadcast or analyzed for the purposes of background noise analysis or voice printing. Since even short voice clips occupy large file sizes, GPRS or other high speed mobile data services are needed. JOB DISPATCH Non-voice mobile services can be used to assign and communicate new jobs from office-based staff to mobile field staff. Customers typically telephone a call center whose staff take the call and categorize it. Those calls requiring a visit by field sales or service representative can then be escalated to those mobile workers. CORPORATE EMAIL With up to half of employees typically away from their desks at any one time, it is important for them to keep in touch with the office by extending the use of corporate email systems beyond an employee's office PC. Since GPRS capable devices will be more widespread in corporations than amongst the general mobile phone user community, there are likely to be more corporate email applications using GPRS than Internet email ones whose target market is more general. INTERNET EMAIL Internet email services come in the form of a gateway service where the messages are not stored, or mailbox services in which messages are stored. In the case of gateway services, the wireless email platform simply translates the message from SMTP, the Internet email protocol, into SMS and sends to the SMS Center. In the case of mailbox email services, the emails are actually stored and the user gets a notification on their mobile phone and can then retrieve the full email by dialing in to collect it, forward it and so on. By linking Internet email with an alert mechanism such as SMS or GPRS, users can be notified when a new email is received. REMOTE LAN ACCESS Remote LAN applications encompasses access to any applications that an employee would use when sitting at their desk, such as access to the intranet, their corporate email services such as Microsoft Exchange or Lotus Notes and to database applications running on Oracle or Sybase or whatever. The mobile terminal such as handheld or laptop computer has the same software programs as the desktop on it, or cut down client versions of the applications accessible through the corporate LAN. This application area is therefore likely to be a conglomeration of remote access to several different information types- email, intranet, databases. This information may all be accessible through web browsing tools, or require proprietary software applications on the mobile device. The ideal bearer for Remote LAN Access depends on the amount of data being transmitted, but the speed and latency of GPRS make it ideal. FILE TRANSFER You may download sizeable data across the mobile network. This data could be a presentation document for a traveling salesperson, an appliance manual for a service engineer or a software application such as Adobe Acrobat Reader to read documents. The source of this information could be one of the Internet communication methods such as FTP (File Transfer Protocol), telnet, http or Java- or from a proprietary database or legacy platform. Irrespective of source and type of file being transferred, this kind of application tends to be bandwidth intensive. It therefore requires a high-speed mobile data service such as GPRS, EDGE or 3GSM to run satisfactorily across a mobile network. HOME AUTOMATION Home automation applications combine remote security with remote control. Basically, you can monitor your home from wherever you are- on the road, on holiday, or at the office. If your burglar alarm goes off, not only do you get alerted, but you get to go live and see who are perpetrators are and perhaps even lock them in. You can program your video, switch your oven on so that the preheating is complete by the time you arrive home and so on. Your GPRS capable mobile phone really does become like the remote control devices we use today for our television, video, hi-fi and so on. As the Internet Protocol (IP) will soon be everywhere- not just in mobile phones because of GPRS but all manner of household appliances and in every machine- these devices can be addressed and instructed. A key enabler for home automation applications will be Bluetooth, which allows disparate devices to inter work. WHAT IS BLUETOOTH TECHNOLOGY ? Bluetooth, named after the renowned Danish King, Harold Bluetooth, is a short-range wireless connectivity standard. Bluetooth is capturing the minds of the present day technologists, as a technology enabler for the wireless unification of a wide variety of portable devices like mobile PCs, mobile phones and the like. It does away with the cables and enables voice and data transfer between the devices through wireless networks called piconets. The primary segments identified for Bluetooth application are: Cellular & PCS Mobile Phones, Digital Cordless Phones, Data Access Points, PC Cards and Adapters , Notebook & Desktop PCs, Handheld PCs & Palm Companions / PDA s, Digital Still Cameras, Output Equipment, Automotive and Industrial & Medical applications. The technology behind it: Bluetooth is a Radio Frequency (RF) specification for short-range, point-to-multi-point voice and data transfer. An advantage of Bluetooth is it's similarity to many other specifications already deployed and it's borrowing of many a feature from these specifications. The 2.4GHz band is used by IEEE 802.11 to enable wireless LAN connectivity. Bluetooth borrows specifications to enable file sharing and data transfers between devices from IrDA (a wireless specification that uses InfraRed light to connect devices). HomeRF SWAP, a specification aimed at small network of devices for the home environment, is another source for Bluetooth. It is omni-directional and has a present nominal link range of 10cm to 10m, which can be extended to 100m, with increased transmitting power. Bluetooth operates in the 2.4GHz Industrial-Scientific-Medical (ISM) Band and uses a Frequency Hop (FH) spread spectrum technology in which packets are transmitted in defined time slots on defined frequencies. A full duplex information interchange rate of upto 1Mbps may be achieved in which a Time-Division Duplex (TDD) scheme is used. A Bluetooth System: A Radio Unit - consisting of a radio transceiver, which provides the radio, link between the Bluetooth devices. A Baseband Unit - a hardware consisting of flash memory and a CPU. This interfaces with the radio unit and the host device electronics. Link Management Software - a driver software or firmware which enables the application software to interface with the baseband unit. An Application Software - this implements the user interface and is the application that can run on wireless. BLUE TOOTH USAGE MODELS The usage model being presented below are those which have been identified by the Bluetooth SIG's marketing group and helps us to get a peep into the vast areas of application of this wonderful standard. The three-in-one phone: It can work as cordless phones connecting to the public switched telephone network at home and office and thus incurring the fixed line charge. It could function as a walkie-talkie with other telephones in the same office or building, without incurring any charge. This telephone can also connect to the cellular infrastructure and function as a cellular phone, incurring cellular charges. At home, your phone functions as a portable phone (fixed line charge). When you're on the move, it functions as a mobile phone (cellular charge). And when your phone comes within range of another mobile phone with built-in Bluetooth wireless technology, it functions as a walkie-talkie (no telephony charge). The Internet Bridge: In this usage model, mobile phone or cordless modem functions as a modem to the PC, providing dial-up networking and fax capabilities without a need for physical connection to the PC. Use your mobile computer to surf the Internet wherever you are, and regardless of whether you're cordlessly connected through a mobile phone (cellular) or through a wire-bound connection (e.g. PSTN, ISDN, LAN, xDSL). The Interactive Conference: Here, multiple data terminals, use a Local Access Network (LAN) access point as a wireless connection to a LAN. Once connected, the data terminals operate as if they were connected to the LAN via dialup networking. The terminals can access all of the services provided by the LAN. In meetings and conferences you can transfer selected documents instantly with selected participants, and exchange electronic business cards automatically, without any wired connections. The file transfer usage model offers the ability to transfer data objects from one device to another. Object types include, among others, ***.xls,***.ppt,***.wav,***.jpg,***.doc files or entire folders, directories or streaming data formats. Also, this offers a possibility to browse the contents of the folders on a remote device. The Ultimate Headset: The Headset, can be wirelessly connected for the purpose of acting as a remote device's audio input and output interface .The headset increases the freedom of movement while maintaining privacy. The headset can be typically used with a cellular headset, cordless handset or personal computer for audio input and output. This headset will also have the ability to answer incoming calls and then terminate them without physically manipulating the telephone handset. Connect your wireless headset to your mobile phone, mobile computer or any wired connection to keep your hands free for more important tasks when you're at the office or in your car. The Automatic Synchronizer: This provides a device-to-device synchronization of the personal information management (PIM) information. Synchronization requires business card, calendar and task information to be transferred and processed by computers, cellular phones and PDA s, utilizing a common protocol and format. This involves, automatic synchronization of your desktop, mobile computer, notebook (PC-PDA and PC-HPC) and your mobile phone. For instance, as soon as you enter your office, the address list and calendar in your notebook will automatically be updated to agree with the one in your desktop, or vice versa. IrDA AND BLUETOOTH IrDA-Data (IrDA -> Infra-red Data Association) is another short-range wireless connectivity standard with an installed base of 50 million units, by now. IrDA is a point-to-point, narrow angle (30 degree cone), ad-hoc transmission standard designed to operate over a distance of 0 to 1 meter and at speeds of 9.6kbps to 4Mbps, which is expected to increase to 16Mbps. While the application areas of Bluetooth and IrDA overlap, they are not competitive standards, necessarily. The short range, narrow angle of IrDA allows the user to aim, in point-and-shoot style at a targeted recipient, for example in a conference hall. Close proximity to the other person is natural in a business card exchange situation and the short range is an advantage of IrDA for such applications. The directional nature of IR enables a low level security because of direct line-of-sight nature; but it provides for, no security at the link level. There are security loopholes as it is possible to eavesdrop on a conversation by detecting reflected light and filtering out the surrounding ambient noise. In contrast, Bluetooth addresses the security concerns by providing authentication and encryption in its baseband protocol. Authentication relies on a challenge-response protocol utilizing a secret key, personal identification number or PIN. Bluetooth devices talking to one another should have the same PIN. The protocol allows each device to authenticate the other. After the devices are authenticated it is possible to encrypt the transmission for added security. Thus, it is expected that while in some devices both IR and Bluetooth may co-exist, for the other applications, the choice of Bluetooth and IR will be based on the applications and required usage models. Mind-boggling technology like the Bluetooth and GPRS, is on its way to make communications in the future, a completely different ball game. A ball game with a win-win situation. Pave way for the future with these technologies then. Curtsy Labels: mobile phone tips
Mobile Phone Health Issues mobile phone tips
| Mobile Phone Health Issues |
One of the most common sights we see these days,
is that of people with their mobile phones next to their ears. A boon
for better communication, cell phone usage nonetheless has many health
hazards. Various studies indicate that the emissions from a cell phone
can be extremely harmful, causing genetic damage, tumors, memory loss,
and increased blood pressure and weakening of the immune system. This
is alarming information, and one has to take into account all these
factors..
|
|
CELL PHONES AND HEALTH |
Though there is no evidence of cell
phones causing cancer or any such illness, but the suspicion, or fear
of the same is not baseless either. The electromagnetic radiation from
cell phones does have a potential link to cancer. The fact that this
radiation is invisible, intangible, and enters and leaves our bodies
without our knowledge makes it even more intimidating.
Possible hazards:
- Two minutes of exposure to emissions from mobile phones can
disable a safety barrier in blood causing proteins and toxins to
leak into the brain, could increase chances of developing
Alzheimer's multiple sclerosis and Parkinson's. (Scientists at
Sweden's Lund University)
- Scientists say exposure to the
phones' low-level radiation causes red blood cells to leak
hemoglobin and can lead to heart disease and kidney stones.
- Recent studies suggesting a link
between cell-phone use and brain tumors, and the possibility that
the microwaves could ignite petroleum fumes at gas stations.
- A cell phone unit, or
communications tower, has so many of thee radiation emanating
gadgets. This can be a problem for its immediate environment.

SPECIFIC HEALTH CONCERNS |
Cancer /
Tumors
Studies have been conducted suggesting that rats that have been
exposed to microwaves similar to the sort generated by mobile phones
but more powerful, showed breaks in their DNA which could indicate an
adverse effect. Also, mice exposed to radiation for 18 months
developed brain tumors. Though of course, these studies are not
concrete proof.
Blood Pressure
It was observed that people using cell phones were prone to high blood
pressure. Again, there isn't any concrete evidence of the same.
Pregnancy
A study at the University of Montpellier in France was carried out on
6000 chick embryos and suggested that the heavily exposed chick eggs
were five times less likely to survive than the control group.
This study raised questions about possible effects on pregnant women
but it has not yet appeared in peer-reviewed scientific literature or
been reproduced, so its findings are difficult to assess.
Headaches, Heating Effects, Fatigue
A study brought out that longer the people used mobile phones, the
more likely they were to report symptoms such as hot ears, burning
skin, headaches and fatigue.
The study did not include a control group (that is people who do not
use mobile phones, to make a comparison); therefore the symptoms
reported could have been caused by any number of other factors in the
mobile phones users' environment, such as working with computers,
stress, driving or reading.
Memory
There have been various studies into the connection between mobile
phones and memory loss. A study looked into the effect of
radiofrequency (RF) on the section of rats' brains that is linked with
the memory. The results showed that RF could modify signals in the
cells in a part of the brain that is responsible for learning and
short term memory.
Posture (holding phone between raised
shoulder and ear)
Some researchers claim that holding a mobile phone between the raised
shoulder and the ear could have a damaging effect on muscles, bones,
tendons and discs. These problems would apply equally to a cordless
phone or a landline phone as to a mobile phone and are the effect of
bad posture.
Mobile Phones and Children
Because of their smaller heads, thinner skulls and higher tissue
conductivity, children may absorb more energy from a given phone than
adults.
|
|
|
PREVENTION TIPS |
- Cell phones should be used for
emergencies, and not for long conversations.
- A small chip-like cell phone
microwave radiation protection device is available, which has the
ability to absorb electromagnetic energy waves from your mobile
phone. It helps in reducing the potential harmful effects of these
emissions to the human body.
- Using a mobile headset is a good
idea, you don't have to hold phones next to your ears all the time
- Use a hands free mobile car kit
while driving, without taking your hands off the steering wheel
|
|
|
|
THE WHO (World Health
Organisation) RULES |
- Mobile phone users should limit their exposure to harmful
radio frequencies by cutting the length of calls.
- Hands-free devices cut exposure by keeping the instrument away
from the head and body.
- Driving cum mobile phone talking should be banned.
- Mobile phones should not be used in Intensive Care Units of
hospitals as they can pose a danger to patients by interfering
with the working of pacemakers and defibrillators.
- People with hearing aids should not use mobile phones.
- Base stations, which have low powered antennae on their
terrace to communicate with cell phones, should not be located
near children's schools and playgrounds.

CELL PHONES WHILE DRIVING |
Studies indicate
that a lot of car accidents have happened, while the driver was on
the phone. This is because while driving, one obviously needs to
concentrate, and talking on a phone doesn't help. Some countries
like Portugal have banned the use of cell phones, which may not be
very practical, as their main use is to be reachable while you are
on the move. Thus, it is important to take certain precautions
while driving: |
- Position your phone within easy reach so that you don't have
to take your eyes off the road.
- Get to know the features of your cell phone - speed dial,
redial, voice mail, they can be your lifesaver. But don't dial and
drive at the same time. Use a hands free kit.
- Avoid using a phone when road conditions are hazardous or
traffic is heavy. You can let your voice mail take messages and
then call back later.
- Don't engage in stressful conversations that may distract your
attention from the road.
- Don't take notes or look up phone numbers whilst driving, wait
till you can pull over.
- User abbreviated speed dialing. In fact, voice activated
dialing is even better. It leaves both hands free. Frequently
called numbers can be programmed.
- Have an answering machine installed that could take messages
until you can return the calls. Let your co-passenger handle the
calls if you are not travelling alone.
|
Globalisation is the new mantra. In this age, it is very difficult
not to have technology. But with technology, come certain hazards. The
only way to beat these is again, better technology. Electromagnetic
radiation is everywhere. More and more wireless communication services
(cellular phones, paging, wireless Internet) are expected so is the
artificial electromagnetic radiation. It seems that there is no way to
reverse this trend. Scientists and engineers are developing better and
safer wireless systems and devices. Smaller cell size, better base
station antennas and other more advanced technologies will allow
future cell phones to radiate much lower power. So one can only hope
that cell phone hazards will be reduced.

FREEDOM…JUST A CLICK AWAY
Wired…are you? No longer.
Lets take a step in to the wire free world of cellular phones. Small, big,
slender, bulky, they are available in all sorts of sizes. Once upon a time
treated as a status symbol, cellular phones have now become a frequent
sight. The service providers too, have gone a step ahead in offering
competitive rates, making the wire free world an absolute rage in these
present times. However it's not only the service that most people are
interested in. Deep thought and scrutiny is also given to the instrument
one is purchasing. Numerous companies have plunged in offering a variety
of fancy instruments. Once again, the manufacturer has placed the consumer
on the highest scale of preference, giving him a colossal amount of models
depending upon price, feature, size, etc. Along with the users attitude,
the manufacturer as well has become articulate in delivering the best
product to their buyers.
How are manufacturers actually trying to woo their customers? The answer
is simple. Innovative functions are constantly being introduced in cell
phones to make communication as simple as it can be. 'Coming Closer' is
the key word. Due to the superior expertise applied, cell phones are a
fine example of the world getting more and more close. Undoubtedly, 'an
ode to technology'. Interactive features are what make the consumer tick
today. Ranging from Voice Dialer, Internal Vibrating Alert To Infra Red
and Enhanced Full Rate Speech; they are plenty, they are new and they are
for you! That's right. No longer does you mobile phone serve you as a
device, merely to make or receive calls. With the abundant features
available to you in that 6-inch wonder, life definitely becomes simpler
and easily accessible too. Ranging from Travel, Weather and Shopping Info
To Dial A Pizza and Order A Bouquet, cellular services have emerged as a
new digital revolution in this existing era.
GET
MORE…. FROM YOUR CELL
As usual, lets get the
factual inputs right from the consumer's viewpoint. Speaking of features,
one of the most popular is that of a 'Voice Dialer'. A voice recognition
system that allows you to dial a telephone number stored in your phone
memory by just saying the person's name. You could store telephone numbers
and verbally record the names of people you wish to fill up in your
phonebook / memory. The most suitable for today's hassle-free world of
pace and time, Voice Dialer provides an almost effortless dialing system
to its users. Just say the name and abracadabra… your phone is already in
the process of connecting you to the dialled call. One such lucky user of
this incredible function is Mrs. Seema Lal. " I think it's a real boon.
Specially while driving. While dialing the number manually one can get
distracted, but this is a real treat. Just call out the caller's name and
you are already getting connected." She explains gladly. Long, long ago
when communication modes were scarce, imagining such a possibility would
be laughed upon. But now it's all there right in front of our eyes. Too
good to be true!
Yet another interesting feature is the Enhanced Full Rate Speech (EFR).
This feature helps in reducing the background noise that gets transmitted
along with your voice while speaking on the phone. Highly advantageous in
order to deliver an audible and a clear speech, this feature is just the
apt requisite for our ever - so - crowded trains and buses. Mr. Ravi
Khanna, a stockbroker is a loyal commuter of our dear old western railways
since a long time now. " Traveling from Churchgate to Borivali is my
everyday routine and since I'm into shares most of my work is done on my
cellular phone. Earlier it used to be impossible, but now due to this
special EFR function, conversing on the mobile has turn a lot better.
Thankfully, my phone has turned in to a mini mobile office" says a
satisfied Mr. Khanna. Whether the never - ending problem of our city's
noise pollution is solved, cell phones have indeed come up with a credible
solution. This feature is essentially supportive in theatres, crowded
streets and huge public places. Technology for thought…sure has done some
wonders
SPEAKEASY
'No strings attached'!
That does sound good to the ears. Some skilled minds have made
possible that it feels good to the ears as well. We are talking about
the impressive 'Hands Free Kit' available with some cellular handsets,
redefining freedom in the most amazing manner. Trendy and popular, the
hands free kit is very well accepted by today's generation. " To avoid
that extra head ache of actually holding the instrument while
corresponding, a hands free is just the right thing." Says Mr. Vishal,
a young production executive, who simply detests the idea of carrying
the phone around all the time. "I specially chose an instrument with
the hands free feature to avoid that extra pain on my ear and hand,"
he laughs. The hands free is included in the kit by the |
manufacturing company
itself. One simply has to insert the plug in the instrument and wear
its earphones and then J-U-S-T T-A-L-K. Your mobile being in the
tiniest corner of your attire will not make a difference to your
dialogue. Another added advantage of a hands-free is for motorists and
bike riders who cant afford talking while driving/riding. A sweeping
fine of Rs. 500, and undue diversion caused on the road are reason
enough for many to choose a cellular instrument with this facility.
However sleek a cell phone, nothing is more cool and compact than a
hands free kit. |
PASS IT ON THE DIGITAL WAY!
Ever thought information
could be passed on in the mobile manner… Here's one more cherry in the
cellular pie. This one is called 'Infra-red'. Infrared is the most
exclusive feature available in a few elite cellular phones wherein you can
send and receive data from computer to mobile and mobile to mobile
(provided all the instruments are Infra Red compliant). The process
applied is fairly simple in which both the parties having the phone have
to be physically present with each other for the exchange of data to take
place. Mr. Scott, Vice President of a leading pharmaceutical company is
very proud of his cellular wonder. "There have been many occasions where I
need some important notes on my cell from my computer. Seemed like a
far-fetched contemplation some while ago. No more hassles! I just have to
transfer the data from my computer to my cell phone and sometimes even
vice - versa. Now isn't that outstanding. My phone actually performs
technological wonders" he exclaims with a broad grin. In addition to
sending and receiving data from computer to phone, Infra red is also used
amongst cellular users to exchange data such as business notes, telephone
numbers, calendar notes etc. These features in cellular phones are
comprehensive as well as highly beneficial to the end user.
ITS
ALL… IN THE PHONE
Moving on to something more
amusing, but certainly worth a thought. How many times have we seen (or
rather experienced it ourselves) people getting pathetic looks in
theatres, meetings, conferences, auditoriums etc? No… it's not because of
their appearance. The reason is that shrieking ring of that tiny mobile
which gets across angry eyes and gritted teeth. There is a peaceful way
out to this repetitive nuisance. Its called 'Internal Vibrating Alert'.
Most phones have this function wherein the user can program his phone to
physically vibrate instead of a ring tone, in accordance with his
environment. This feature prevents the phone from making any kind of
sound, saving the user unwanted embarrassment. Along with the vibrator,
there are other modes such as 'silent', 'light only' and 'vibrator +
ring', but the 'internal vibrator' still remains immensely popular. This
feature also helps in crowded places where one is unable to hear the ring.
HIP 'N' HAPPENING
One of the entertaining
features provided by the manufacturers is the availability of games in
cellular phones. Usually instruments have three to four games in their
menu such as snake, logic, memory etc. Being extremely enjoyed amongst
college students and young executives, these games are brainteasers
and keep you entertained too. Several other features such as Calendar,
Large Screen Display, Changing Backlight Colour, |
Musical Ringing Tones,
and Bizarre Graphics are available on latest cell phones that are
attractive and increase the phone value. |
|
"Hi I'm not available right now. Kindly leave your message and telephone
number and I'll get back to you". That's sounds rather familiar! No, Its
not one of those answering machines switched on. Ditto! It's available on
your cellular network too. Thoughtfully called Voice Mail, this feature
allows you to programme your phone to go on voice mail when you cannot
answer the phone (just keeps ringing), when the phone is switched off or
is in no or limited range. The network providers offer Voice Mail services
at a good bargain and give you a chance to suit the options as per ones
requirement. "No worries when my phone is in low range or switched off.
The voice mail system in my phone helps me to get all my messages and
revert back to them accordingly. A very well thought about feature, I must
say." Says Mr. Anand Kumar, a cloth merchant. A regular traveler, at times
finds himself with places with less network. However, with a Voice mail in
his cellular, he is completely carefree.
Other utility oriented features include Call Divert, Call Wait etc. Call
Divert enables you to divert your phone to your voice mail, fax line or a
separate LAN line number as and when essential. It also helps when your
phone is put off or when one does not wish to answer calls. Similarly,
Call Wait allows you to hold one call and answer the next incoming one
(swap) at one time. In addition to that you can speak to all the parties
simultaneously through the conference facility available. In totality,
multi conference (more than 4 parties together) is also possible. Features
such as Voice Mail, Call Wait, and Call Divert etc., can be availed
through your service provider at monthly subscriptions and notifications.
These features are incredibly useful in managing one's time and
correspondence in the most efficient manner. Indeed, cellular phones keep
you connected round-the-clock.
