<< GPRS is NOT an air interface >> Right, Sam. From the folks that brought us "A Comparison between GPRS and cdmaOne Packet Data" on the CDG website: "The General Packet Radio Service (GPRS) is a new nonvoice 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. 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." Source: Simon Buckingham "An Introduction to the General Packet Radio Rervice " Mobile Lifestreams Limited Issued January 2000 GSMA Web site << Anybody who says it is, does not what the hell he is saying. >> Simon is as bad as me in this regard, I guess. <g> For the moment, I'll stand by my original statement that was made on another thread. << Please read closely the link you offered Eric. ... I would have expected you to read your source through this point >> I always read the links I offer, and in this case, I read this source very thoroughly, several times, and I am following the evolution of GPRS and GRX very closely. The particular link I offerred was chosen because it goes into more detail in describing the GPRS air interface than others I have bookmarked. << As of six weeks ago, a major supplier that I personally have seen could only make it work around 20 Kb/sec while the mobile was moving at parking lot speeds, and it still drop calls >> You are one up on me. It will be interesting to see if this timetable (developed by Mobile Lifestreams in conjunction with GSMA) is met. * Summer of 2000 - First trial GPRS services become available. Typical single user throughput is likely to be 28 kbps. * Start of 2001 Basic GPRS capable terminals begin to be available in commercial quantities * Throughout 2001 - Network operators launch GPRS services commercially and roll out GPRS. - Vertical market and executive GPRS early adopters begin using it regularly for nonvoice mobile communications * 2001/2 - Typical single user throughput is likely to be 56 kbps. New GPRS specific applications, higher bitrates, greater network capacity solutions, more capable terminals become available, fuelling GPRS usage * 2002 - Typical single user throughput is likely to be 112 kbps. GPRS is routinely incorporated into GSM mobile phones and has reached critical mass in terms of usage. Best, - Eric -
