Abstract
A novel base station for cellular wireless communications based on a modular structure is provided. The modular cellular wireless communication base station includes a plurality of active radiator modules (ARM's) located at a desired antenna location, a beam forming network controlling relative amplitudes and phases of each of the modules and an RF front end. Each module (100) includes at least one antenna (ant) for transmitting and receiving, a transmitter having a power amplifier, and receiver.
