Abstract: A communication system includes a first communication module, and a second communication module. The first communication module may receive a first type of communication signal (e.g. a mobile telephone signal) and convert it into a second-type of communication signal (e.g., a millimeter wave radio signal). The first type of communication signal may be a mobile telephone signal from a first fire fighter's mobile telephone who is located outside of the building. The first communication module may transmit the second-type of communication signal to the second communication module.

Abstract: 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.

Abstract: A stored program amplifier compensation apparatus utilizing sensing elements to provide the operational states of an RF power amplifier to a controller processor unit which utilizes the operational data to provide a bias control signal to the RF power amplifier. Look-up tables which are stored in the controlled processor unit, contain a bias control signal for all the possible operational combinations.
