<...HDR may be limited to fixed apps. Still very interesting> Yes, but fixed connections are something very different to (even slightly) mobile connections. For example, directional antennas can be used, Yagi or even more directional arrays, with 12-24.. dB gain in a fairly-very narrow beam, which also minimizes multipath fading, amplitude variations (but not far-near if CDMA). Bluetooth and different WaveLANs can do the final 10-30 meters, etc. One ISP-provider is at the moment (supposedly) setting up wireless internet basestations, connections in Finland based on Lucent WaveLan availability: saunalahti.fi $40 per month, 1Mbps, 2.4Ghz (line of sight), 100mW, if it works, but the first rumours are not that promising. However, my own view is much the same as the tech commissarie of EU, Erkki Liikanen (finnish socialist), explained today in finnish TV, that the future will be a mix of: - telephone cable were it exists - TV-cable (same, bidirectionality??) - fiber (backbone, lots of digging) - 3G (continuation of GSM) and - fixed wireless DSL to fill out the gaps (- electric power cables, but dimmers are tough) All competing and some better, some worse in some applications and enviroments, existing infrastructure. To me it seems as fixed wireless is more a question of setting up antennas, just as fiber is mostly a question of digging (and especially reconnecting what was cut when trying to lay down another one) As a matter of fact I'm trying to make a dent in the local GSM+copper operators market by making my ISP provider to set up a wireless (CDMA) link to my house, but it looks like it is easy for some 40-50 users but then the cocktail effect starts setting in, nobody gets any data. That is, it seem to get pretty complicated with some 100-500 users?? (in small-town Finland the copper wire running to every house is still a valuable thing) Ilmarinen. (still a strong monthly supporter of Sonera but balanced by increase in share)
