Method and apparatus for high throughput multiple radio sectorized wireless cell
First Claim
1. A method performed by a first wireless cell for improving a throughput between the first wireless cell and a first wireless client, the method comprising:
- sending a first data to the first client using a first antenna of a plurality of antennas and a first channel of a plurality of channels;
sending a second data to a second wireless client using a second antenna of the plurality of antennas and a second channel of the plurality of channels;
receiving a first message from the first client that the first channel does not provide a sufficient throughput to the first client; and
selecting a first different channel for communication with the first client, wherein;
the first wireless cell comprises the plurality of antennas and the plurality of channels;
the first client comprises the plurality of channels;
the second client comprises the plurality of channels;
the first antenna comprises a first physical sector having an angle of coverage less than about 270 degrees;
the second antenna comprises a second physical sector having an angle of coverage less than about 270 degrees;
the first physical sector overlaps at least 30 percent of the second physical sector thereby forming a virtual sector;
the first channel and the second channel comprise different channels;
the first client and the second client are positioned inside the virtual sector;
the first wireless cell simultaneously communicates with the first client and the second client using the first antenna and the second antenna respectively.

Abstract
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.
