Abstract:
1. A wireless communication system, comprising: a first base station configured for communication within a first cell and operating in a first carrier band; a second base station configured for communication within a second cell and operating in a second carrier band that is distinct from the first carrier band, wherein the second cell is smaller than the first cell and configured within the first cell; a repeater co-located with the second base station, wherein the repeater is configured for receiving signals with a repeater service antenna within a service area and re-transmitting the received signals with a donor antenna as a directed beam to the first base station the repeater includes a filter to attenuate frequencies outside of the first carrier band wherein the first repeater service antenna has an omni-directional cardioid pattern with a null placed in the direction of the first base station; a plurality of additional base stations each configured for communication within a corresponding plurality of additional cells, wherein each additional cell is smaller than the first cell and is located within the first cell; and a plurality of additional repeaters each co-located with a corresponding additional base station, wherein each additional repeater is configured for receiving signals with an additional repeater service antenna within a corresponding additional service area and re-transmitting the received signals with an additional repeater donor antenna as a directed beam to the first base station, wherein each of the additional repeater service antennas has an omni-directional cardioid pattern with a null placed in the direction of the first base station.
