w molloy: Curious if you could cite a reference to the report from which you have posted an excerpt. The last two paras are of considerable interest for different reasons: The first which confirms that HDR uses TDMA. The second that wireless PC modems will incorporate HDR. and that the US will continue to lead in wireless internet. "Ironically, HDR is a dynamically adaptable form of power controlled TDMA which fits seamlessly into unused 1.25 megahertz CDMA channels. (Irwin Jacobs reminds us that he and his Qualcomm team won TDMA patents back when they were at a company called Linkabit). With HDR coming on in 2001, you will be able to plug your notebook into your CDMA cellphone and get faster access than your office T-1 line (1.544 Mbps). Soon the HDR chipset will become your PC's onboard wireless modem. In recent trips to Tokyo and London I was repeatedly assured that the U.S. is behind in wireless data. But for data, U.S. penetration is, in fact, slightly greater than Japan's and Europe's, and U.S. data advances come in the context of twofold higher Internet use. With Qualcomm launching a superior technology today, the U.S. will continue in the lead in wireless Internet." Clark, engineer or others, any comments on why and how HDR is based on TDMA vs CDMA? Remember that the Taiwan laptop makers were planning on using CDMA in their laptops. Does anyone know whether those initiatives are CDMA upgrades IS 95 B or C or 1XRTT as initial CDMA 2000 or are they HDR TDMA? One most interesting result of all this seems to be that the Q will have two separte paths for data HDR (TDMA) 1XRTT and the 3XRTT (CDMA) Do I understand this correctly? Anyone? Chaz
