gprs global communication 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 www compareindia com

new technologies of mobile phones

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’!

learn all features of mobile phone

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.

Select just the right amount of laptop memory. Too little and your machine will hang in slow motion; too much and you’ll pay through the nose.

Even in this day and age of high-speed cable broadband Internet access, you still need the humble laptop modem.

Ethernet – or cable – is the standard way of getting connected to the Internet at many locations, like the office or the hotel.

Look – no wires. Grab yourself a laptop computer with wireless Internet connectivity and leisurely read your email down at the local coffee shop.

USB is short for Universal Serial Bus and it’s quite simply the most important port to look for on any laptop computer.

Firewire offers fast access to external devices, but you may not need one on your laptop unless you’re doing something special.

Special types of audio video (av) ports to look for, especially if you plan on using your laptop computer for business presentations or you want to borrow your laptop’s DVD player for watching movies on your television.
