ABSTRACT:
A low power, multi-function cellular television system for transmitting signals at super high frequencies. Each cell transmitter radiates signals with one polarization over one sector, and signals with a different polarization over the balance of 360.degree.. Sectors of adjoining cells are aligned to minimize interference from the adjoining cell. Adjoining cells may transmit different pluralities of carrier frequencies which are interleaved to minimize interference further, with each cell having one set of transmitted frequencies radiated for both polarizations, occupying at least 90% of a band used in common for the system.
