<p>The present invention relates to a millimeter-wave communication system for one-way and/or two-way video, voice and data services that leverages cell-site diversity, subscriber-unit adaptability and a reflection dominated propagation model. To this end, a variety of omni-directional and directional antenna plans, cell-site structures and adaptive reception/transmission plans are envisioned in the present invention. Cell-site diversity is employed and permits shadowed subscriber units to be serviced from the best choice of the surrounding cell-sites based upon millimeter-wave propagation efficiency and not geometric convenience. Cell-site diversity is used to mitigate the ill-effects of environmental and atmospheric factors. Finally, the present plan reduces the reliance on repeaters by using statistically optimal conditions for cell-site selection with reflection based models rather than line-of-sight models, as relied upon in the prior art.</p> |
