 GPRS :
GPRS (General Packet Radio Service) is a packet based communication service for mobile devices.
The service sends "packets" of data over a radio wave (on the GSM network). Packet switching works like a jigsaw puzzle: your data is split into many pieces, then sent over the network and reassembled at the other end. The service joins together multiple speech channels to provide higher bandwidth data connections for GPRS data users. The total radio bandwidth is shared between the voice users and the data users.
Speed :
GPRS may well be a relatively less costly mobile data service compared to SMS and Circuit Switched Data.
Immediate Transmission :
Using GPRS the information can be sent or received immediately. No dial-up modem connection is necessary.
Efficiency :
Rather than dedicating a radio channel to a mobile data user for a fixed period of time, the available radio resource can be concurrently shared between several users and the large numbers of GPRS users can potentially share the same bandwidth. Thus GPRS should improve the peak time capacity of a GSM network.
Supported Applications:
1. WAP: GPRS would allow users to explore the Internet or their own corporate networks more efficiently.
2. Chat: 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.
3. Support for still images, moving images, audio and other and various kind of file transfers. |
