Dennis: True. But do you seriously suggest that HDR is unproven? There is a huge gap between what is on track and what isn't. CDMA 2000 (and HDR (1xEV) is on track. There have been "tests" of HDR (1xEV) under real world conditions in the US and Japan. Perhaps these are flawed and meaningless, but my bet is that these tests are well designed and reliable. But the proof of the pudding will be in the eating, of course. Best. Chaz

FWIW, I found this inside a longer article. More grist for the mill. The device manufacturers argue that because 3G can theoretically transmit data at 144Kbps when moving at high speed, 384Kbps at low speed, and a whopping 2Mbps when stationary, information can be delivered quickly when you're on the move. However, according to both local and international telecommunications analysts, transmission speeds will get nowhere near anticipated levels. A report by a US analyst, the Shosteck Group, concluded cost and operational reasons would limit the speed to between 30 and 40Kbps slower than a 56Kbps dial-up modem. "For many people who had been told that 3G would support 384Kbps and beyond, this will prove to be a major disappointment," the study found. Locally, the pundits are more optimistic, saying speeds will probably average between 100Kbps and 150Kbps, possibly even hitting 300Kbps. From: it.mycareer.com.au BTW, where is that Shosteck Group paper on TDMA conversion we were promised by the CDG? P.S. This snippet is interesting too. GPRS doesn't seem so cheap anymore. But perhaps the greatest misconception is that GPRS, and later 3G, will offer an "always-on connection". This is not the case; callers will actually be charged a connection fee to access the service, plus a fee for the volume of data transmitted (as opposed to the time spent connected). Like WAP, Telstra will charge a 22 cent connection fee to start a GPRS session. One session lasts as long as you remain connected. And like phone calls which can drop out when you go through a tunnel, so too a GPRS connection. While ambiguously stating that "with GPRS, you can be always online", Telstra makes a point of not guaranteeing "the extent to which a GPRS compatible phone will have access to information on the Internet or anywhere else". If you receive a phone call while in a GPRS session, the service will be suspended until you finish your call and return to continue. However, if you wish to make a call from your terminal, you will need to disconnect, make the call, and then reconnect (another 22 cents) to the GPRS service.

RE: TelecomClick article of interview with the CTO of PCS about 1X testing and deployment. telecomclick.com (print-ready version) The link to this article was posted last week on this or the Buying Range thread. It is an interview with the CTO of PCS on the testing and technical expectations for 1X. I highly recommend reading the article. Here are some key snippets: “In pre-commercial phase … The data rates reached peak performance of 144kb/s consistently, whether close to a cell site or far away. [emphasis added] “ According to [CTO], average data speeds will be more important to consumers. ‘What we think that’ll be and how we’re designing out network is under a loaded condition to be in the 70kb/s range,’ he added.” Later in the article, the CTO talks about improvements in other aspects of the network – vocoders and antennas, and then says “ ‘All of these are additive,’ he said. When you add all of these other capacity enhancements, you can offer improvements 20 times TDMA and GSM [emphasis added] and 35 to 40 times analog capacity…” Again, the full article well worth reading
