LMDS Systems Design in MM-Waves
Characteristics:
- Very high path loss and rainfall attenuation; limited amplifier gain; lack of low-cost and stable frequency sources,
- Difficult to have LOS coverage to all the potential subscribers: few trees along path cause 10-15 dB power loss and severe scattering.
? High service accessibility: To both LOS and Non-LOS users
? High rate services: video (1.5 - 15Mbps)
? Simple access scheme and a high bandwidth-efficiency
? Quality-of-Service Guaranty
