Dave, right now QPSK is the standard for MCNS upstream. Cable labs seemed quite impressed with sCDMA,and Terayon,and CSCO has licensed their technology. LANcity by BAY the most widely deployed cable modem as of now,uses 64QAM downstream and QPSK upstream. COM21 is using a hybrid ATM modem,not sure of the exact modulation. As far as LMDS/MMDS is concerned,they are two fairly different bandwidths. MMDS runs on a narrow bandwidth,about 150 MHZ,and at a lower frequency,and does not have the potential of LMDS. LMDS runs at high frequency(28 GHZ),low power(very low),and has a potentially huge spectrum(over 1 GHZ). Bell South just announced deployment of MMDS,due to the fact they might not be allowed to bid on the auctions for LMDS is February. With 2-way reverse polarization,and digital transmission,this is a formidable competitor and probably a complementary technology to HFC. CVUS has had great success testing LMDS and where the feed isn't a direct line of site,great success in bouncing it off buildings. Rain attenuation is a problem,but that has also been overcome by boosting the signal during rain storms. The spectrum ans potential of LMDS rivals HFC,and the technology is rapidly advancing. And remember the dish is the size of a ping pong paddle,and does not need a fiber build out. HLIT just acquired New Media(not finalized until December),who is supplying CVUS with new digital NICS and headend gear that runs 50 channels at 500 kbps,for a total speed of 48 mbps(impressive). HLIT also is supplying 21st Century with optoelectronics for their Chicago build out that is going to blow TCI out of Chicago. TCI is bleeding all over the country from cities using utilities to compete,to new entrants like 21st Century and Teligent. Hiram
