Chaz, << As you know I am just an observer, but try to keep up >> Well you do a fine job of that although this statement doesn't quite reflect "keeping up" or your generally high standards, IMO: "GPRS ... There is close to zero gain in data speed." Now if we wanted to play the fear, uncertainty, and doubt game, (which I'm sure was not your purpose) one could quote back to that one, with this: June 8, 2001 - Emblaze Systems and Samsung have demonstrated video on demand over a wireless network in Korea ... Eli Reifman said the network uses a version of CDMA technology known as IS95C, ... the service was only capable of data transfer rates similar to those of GPRS. During the demonstration of a streamed weather report, the phone only showed transfer rates of about 10kbit/s, though Emblaze said that "in perfect conditions" it would be closer to 30kbit/s. or: May 30, 2001 - "We conducted tests on 5105 chips from last February and finally judged them unfit at the end of April after they failed to provide the speed of up to 144Kbps that we need," an SKT official said. or: May 15, 2001 - cdma2000 1x is the 2.5th-generation service that bridges the current mobile phone service (2nd) and the 3rd IMT2000 service. ... customers who bought the new breed of phones have reported complaints to sales agencies or outlets that they were unable to make a call with the phones, not to mention, that cutting-edge additional services are unavailable ... "Out of 10 sold out, about 7 has been reported with complaints," said a sales agency source. "Even worse, the complaints are mostly that they can't make a call, not that additional services are unavailable," But as Lakers points out: "we are still in the earlier stage of 1x, so you can expect there are still glitches, bugs and instabilities making the operators and the users more cautious in going 1x in full speed" And so it goes with GPRS which when commercialized will initially offer speeds in the 26Kbit/sec to 52Kbit/sec range. Although not blazing fast, this speed compares to the speeds road warriors are used to, and works for many applications. - Peter Rysavy ... and oh yes, before we see these speeds in a commercial environment we'll probably see only about 20 kbps, and initially probably only a few carriers will boost that with data optimization. Now as for: "'What we all have to do is manage their (consumers) experience moving to 3G with realistic expectations," << [such] comments seem to be coming from those pushing GPRS as an "evolutionary" [sic.] path to 3G ... Could that reflect the performance of GPRS vs expectations earlier? >> Perhaps, or perhaps it is an acknowledgement that IP based packet data is a whole new ball game for voice oriented wireless carriers. There is a "learning" going on, and technology migration, debugging, what have you. The same comments could and should apply to cdmaOne carriers migrating to 1xRTT, 1xEV-DO, or 1xRTT/1xEV-DO. Aside from the more "technical issues" related to GPRS that Peter Rysavy often addresses, the best most current, realistic and sober, current assessment of the challenges facing GPRS carriers is here: Message 15925147 and here: Message 15925200 Now some of the "issues" in that article pertain specifically to GPRS, but if you read it carefully, you will see that some of the issues relate equally to the migration of CDMA from circuit-switched to packet-switched in an IP environment, and some of them even have challenged the Korean carriers who have more experience with packet data than any other CDMA carriers (including KDDI). - Eric -
