<body><h1><a name="Data_Connectivity"></a>Data Connectivity</h1><h2><a name="GPRS"></a>GPRS</h2>The
|
|
|
4 |
General Packet Radio Service (GPRS) enables the cellphone user to stay
|
|
|
5 |
connected to the Internet. The data gets delivered at a rate of around
|
|
|
6 |
56kbits/sec in GRPS network. The technology also allows the mobile
|
|
|
7 |
phone users to get access to applications that were unavailable on GSM
|
|
|
8 |
network due to speed limitation. Blackberry emails and MMS can also be
|
|
|
9 |
sent through GPRS.<br><br>In GPRS, a
|
|
|
10 |
single piece of information is divided into small packets. If the user
|
|
|
11 |
is sending an e-mail, it will be divided into packets. Each packet will
|
|
|
12 |
take the shortest route within the network to reach the destination. <br><br>Cellphone users can email, chat, browse &
|
|
|
13 |
stay connected over the mobile network. GPRS is a 2G technology that
|
| 2187 |
smriti |
14 |
does not allow video streaming, video call etc and users will have to
|
| 2156 |
vrinda |
15 |
move to 3G technology for using these features.<br><br>GPRS is better
|
| 2187 |
smriti |
16 |
& cheaper than the circuit switching technology because users
|
| 2156 |
vrinda |
17 |
are charged only for the total amount of data, which is being
|
|
|
18 |
transported over the network. Whereas, in circuit switching, user has
|
|
|
19 |
to pay the charges even if he is in an idle state.<br><br>The speed of GPRS is determined by factors like:<br><br>a) Slots supported by the device or the base station/service provider.<br>b) Distance between the device and the base station.<br>c) Traffic on the base station.<br><br>See Also<span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;"><span class="Apple-style-span" style="color: rgb(68, 68, 68); font-family: Arial,Verdana,sans-serif; font-size: 13px; line-height: 20px; text-align: left;"><p><a href="http://www.google.com/url?q=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FGeneral_Packet_Radio_Service&sa=D&sntz=1&usg=AFrqEzckvZlYxirempOduwF67CK7ngHFqg" style="color: rgb(0, 51, 204); text-decoration: underline;">General Packet Radio Service</a></p></span></span><h2><a name="EDGE"></a>EDGE</h2>Enhanced

GPRS (EGDE) is an advanced and faster version of GPRS. Described as a
|
|
|
21 |
2.75G technology, EDGE provides a data transfer speed of around
|
|
|
22 |
180kbits/sec, which is three times faster than GPRS. EDGE gives a
|
|
|
23 |
broadband-Internet like experience to the mobile device users. Because
|
|
|
24 |
of higher bandwidth, it provides access to applications like video
