Abstract

An omni-cell (300) for transmitting a cellular communication signal of a single base station channel, includes multiple directional antennas (310.1, 310.2, 31O.n), for the simultaneous transmission of the single channel, and a diversity unit (320). The diversity uni (320) adjusts the cellular communication signal for each of the directional antennas (310.1, 310.2, 310.n) in a manner that provides transmission diversity. Interference between the various directional antennas (310.1, 310.2, 310.n) is thus reduced. The directional antennas (310.1, 310.2, 310.n) may be further arranged to transmit with space or polarization diversity.
