c2, << I recall--perhaps incorrectly--that EDGE, both in the Americas and elsewhere, required a minimum of 384 kbps. >> No. Not really. This is kind of what sparked the UWCC CDG/Qualcomm tiff. The UWCC gained ITU IMT-2000 3G approval for TDMA EDGE which has a (very) theoretical peak throughput of >400 kbps. CDG/Qualcomm who had always referred to 1xRTT as "an interim step to 3G" and 3xRTT as 3G, said "Hold it" ... "wait a minute" ... "if they are 3G even though they can't reach 2 Mbps in a fixed environment, and may not be able to really reach 384 kbps in a pedestrian environment, then 1xRTT which can't do 2 Mbps but eventually theoretically can do 614 kbps in a fixed environment and eventually can do 307 kbps (not 384 kbps) in a pedestrian environment, and initially can exceed 144 kbps (minimum 3G speed) in a mobile environment at 105 km/hr, is 3G too. << Anyway, the phones are whatever they are. The nomenclature won't change their characteristics or their availability. >> That is a plain cold hard fact. In the Americas, carriers using EDGE will call it 3G, and carriers using 1xRTT will call it 3G. I call them both 2.5G. You are free to call either whatever you wish and you will not hurt my feelings. <g> << They are in essence the counterparts to 1x. >> That they are. The higher typical throughput advantage that 1xRTT enjoys today over GPRS goes away when the carriers start providing data services with EDGE and GPRS with CS3/4 instead of GPRS with CS1/2. When all is said and done and the kinks are worked out and networks are optimized (which could, and probably will, take a year or more) end users will not really see much difference between one or the other in terms of effective average throughput. - Eric -
