Wireless network with coordinated sectors to mitigate interference

A method of mitigating interference by coordinating sectors of a wireless network, the method comprising:

• assigning each directional antenna at a first access point to a sector oriented in a direction of maximum gain of the antenna to which the sector is assigned;
• assigning each directional antenna at a second access point to a sector oriented in a direction of maximum gain of the antenna to which the sector is assigned;
• and
• sequencing operation of the antennas in one sector with operation of antennas in another sector to avoid interference between a transmission from an antenna in one sector and a transmission to an antenna in another sector, wherein sequencing operation of antennas comprises:
• operating all antennas assigned to a first one of the sectors on a first frequency during a first time interval;
• operating all antennas assigned to a second one of the sectors on a second frequency during the first time interval;
• operating all antennas assigned to the first one of the sectors on the second frequency during a second time interval that does not overlap the first time interval;
• and
• operating all antennas assigned to the second one of the sectors on the first frequency during the second time interval.

A system comprising:

• one or more data processors;
• and
• a data storage device storing instructions that, when executed by the one or more data processors, cause the one or more data processors to perform operations comprising:
• operating, on a first frequency and during a first time interval, an antenna assigned to a first sector of a first access point, the first sector being defined by a first direction of maximum gain for at least one antenna of the first access point;
• operating, on a second frequency and during the first time interval, an antenna assigned to a second sector of a second access point, the second sector being defined by a second direction of maximum gain for at least one antenna of the second access point;
• operating, on the second frequency and during a second time interval that does not overlap with the first time interval, the antenna assigned the first sector;
• and
• operating, on the first frequency and during the second time interval, the antenna assigned to the second sector.
