Abstract
A radio communication system is provided wherein radio coverage building blocks are used to provide uniform radio coverage to rectilinear floor layouts of buildings. The building blocks are comprised of directional and omnidirectional antennas which are applied to rectangular and irregular layouts. Each building block is divided into multiple small zones and each zone is covered by an antenna. Each antenna in the building block is connected to the same base station through a low loss coupling matrix and all antennas transmit and receive simultaneously. The directional antennas are located near the boundary of the service area. An omnidirectional or directional antenna at the center of the zone may be used to fill the rest of the area.
