Patent ID: 7656825

Claim:
A method comprising: co-locating a first half-duplex modem, a second half-duplex modem, a third half-duplex modem, and a fourth half duplex modem at a base station, wherein: the first half-duplex modem is configured to transmit modulated data to a first half-duplex node located in a first sector during a first time frame on a first channel and to receive modulated data from the first half-duplex node during a second time frame on a second channel; the second half-duplex modem is configured to receive modulated data from a second half-duplex node located in a second sector during the first time frame on the second channel and to transmit modulated data to the second half-duplex node during the first time frame on the first channel; the third half-duplex modem is configured to transmit modulated data to a third half-duplex node located in a third sector during the first time frame on a third channel and receive modulated data from the third half-duplex node during the second time frame on a fourth channel; the fourth half-duplex modem is configured to receive modulated data from a fourth half-duplex node located in a fourth sector during the first time frame on the fourth channel and transmit modulated data to the fourth half-duplex node during the second time frame on the third channel; the modems are configured to transmit and receive in the first time frame substantially simultaneously, and to transmit and receive in the second time frame substantially simultaneously; and the first time frame precedes the second time frame; and forming a first cell coverage area for the base station with the first sector, the second sector, the third sector, and the fourth sector.
