Yes, currently 2.5ghz antenna tech has trouble with building penetration, but MIMO Beam-forming seems to solve problems for both high frequency signals and low. See »www.wimax.com/commentary/spotlig···mforming
With these new antenna technologies, Clear's signal problems will be put to bed.
Can you give me a guarantee that that will ever be commercialized? EVDV, HiperMAN, WiDEN, UMB, etc
