WiMAX for broadband (Score 1)

There seems to be some confusion as to what WiMAX will do, even the industry is confused. WiFi uses a public bandwidth, it shouldn't be used by Telco's because they're will be huge regulatory issues involved. However using WiFi in McDonald's...etc is okay because McDonalds owns the property, and hence can use that bandwidth (but only in that property). WiMAX will used regulated bandwidth (like 3G,GSM etcc..). I'm sure WiMAX uses FDMA, although it could be viewed as TDMA because it doesn't use a different spectrum for upload/download, like 3G. Multipath and Doppler issues can be resolved via vendor specific technologies like rake receives, diversity gain...etc, like it is used in 3G. However doppler will be more of an issue with WiMAX than 3G becuase 3G uses CDMA, which is better for roaming. Whereas FDMA is better for standing still. WiMAX's opportunity is in last mile access to homes, I can forsee people installing WiMAX antenna's for their homes, and using it for Voice, Data, TV (Triple-Play). Instead of having a leased line for the phone, cable for TV and Internet. Wireless is cheaper than rolling out cables, this is particularly pertinent to places like India and China where the bulk of the population do not have telephone lines (hence cannot use DSL).
