To: Uncle Frank who wrote (44092 ) 7/4/2001 1:34:36 PM From: Eric L Respond to of 54805 Frank, << I'd be more interested in how many subs there are on gprs systems >> Just as we saw no figures on subs for the 3 Korean carriers for the first 6 months of "commercial" operation of 1xRTT in Korea, until the Samsung Digevent presentation in April. which stated that through end of March there were 47,000 Korea subs, no figures have yet been published for GPRS. The "unofficial" Korean numbers through June 20, 2001 as reported yesterday by Korea eTimes are:SKT 320,000 KTF 35,000 LG 12,000 SKST 12,000 ------- Total 379,000 1xRTT is comparatively easy compared to GPRS, subs wise with only 4 1xRTT networks commercially launched, compared to >50 for GPRS, to get a handle on. Be assured that EMC Cellular has the GPRS numbers, but they may not announce them till late November or early December, when they do a warmup for the most attended session in Cannes, by previewing their numbers at IBC's "GSM in North America" which they have done now for 6 consecutive years. We may also see some handset sales numbers out of Garner's Dataquest a little earlier than this, but this will be shipments and shipments don't immediately into subs. If I had to take a guess right now, I would guess that GPRS subs is probably <200,000. Until May, there was only one GPRS prototype (Motorola's p7389 which became the p7389i - 'p' standing for prerelease and 'i' standing for improved (prerelease) - which is now called the T260 in its production release, in commercial use, and these were heavily rationed and spread around to carrier customers. This is very comparable to the 1xRTT SK-IM 2300 which was produced in an early production run of 20,000 and which until 1st of 2001 was the only 1xRTT handset available until Samsung released the SCH-100. As vendors ramp to production models we'll see the same type of effect we are seeing in Korea since Samsung launched the SCH-X120 in Korea in April. Nokia is suggesting that 5% of unit volume in handsets this year will be GPRS or 1xRTT (what most research firms call 2.5G). That's 20 million to 25 million subs, and that shipments, not subs. Nokia's intelligence is pretty good, and lets say that conservatively 70% make it in to subscribers hands, that's 14 to 18 million subs, for 1xRTT & GPRS, split maybe 40% 1xRTT (5.5 to 7 million 1xRTT) and 60% GPRS (8 to 11 million). That’s just a WAG. << what the handset battery life is >> Don't have a clue yet, but we'll be seeing reports shortly. Any standard pushes the technology envelope, and battery technology and power amplifier technology affect this critical element. Power amplifiers are coming along faster than batteries. For this reason the initial commercial GPRS handsets will predominately have 1, or 2, timeslots down, (rather than 3 or 4) and 1 up (rather than 2). This of course conserves battery but limits data rate, and the product mix and the performance in this area will start to change dramatically later this year and throughout 2002. << are any gprs systems that are fcc approved at this time >> I do not know. I root around many funny places, but never, never, never, on that particular portion of the fcc web site, although I have a threadmate that does and he must be covered ith cobwebs. When we see GPRS handsets in VoiceStream, Cingular, or AWS stores we will know that the FCC has type approved for SAR, interference, and other factors. FCC of course more stringent than many other (but not all) regulatory bodies, on crucial measurements. Best, - Eric -
