I would like to know what GPRS stand for and how it works with our mobile phones.
It stands for General Packet Radio Service, its a communicatiosn protocol that was introduced to bridge the gap between old GSM and new CDMA standards Its based on Time Division multiplexing, which allows users to access the entire bandwidth of a channel at the time it needs to transmit. Thus it is packet based transmission since the data is transmitted in bursts rather than at one go. This means more users can occupy the same bandwidth, which makes it more efficient than normal GSM.
General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones. It is often described as 2.5G, that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate speed data transfer, by using unused TDMA channels in the GSM network. Originally there was some thought to extend GPRS to cover other standards, but instead those networks are being converted to use the GSM standard, so that is the only kind of network where GPRS is in use. GPRS is integrated into GSM standards releases starting with Release 97 and onwards. First it was standardized by ETSI but now that effort has been handed onto the 3GPP.
