Methods and apparatus for high throughput wireless cells, capable of functioning as access points, are described. The wireless cells may be equipped with multiple radios to increase the amount of throughput available through a single wireless cell. Multiple antennas attached to the radios through RF switches may enable the wireless cell to service multiple clients simultaneously. The physical sectors of the antennas may overlapped to form virtual sectors that provide greater flexibility in client load management and in simultaneously servicing multiple clients. Attenuators may reduce interference from foreign wireless cells or clients. Systems and methods for assigning minimally interfering channels to either physical sectors or to radios to reduce interference between adjacent sectors and overlapping sectors are also disclosed. An antenna horn may also allow any antenna to be used as a directional antenna and may enable the antenna's angle of coverage to be adjusted. The use of multiple antennas on a client to reduce interferences is also described.
