Wireless spectrum management and optimization for dual transceiver operation

An apparatus comprising:

• a first wireless network interface unit to provide access to a wireless network over a first channel for a plurality of wireless devices;
• a second wireless network interface unit to provide access to the wireless network over a second channel for the plurality of wireless devices;
• a memory;
• and
• a processor coupled to the memory, the first wireless network interface unit, and the second wireless network interface unit, wherein the processor is configured to:
• obtain a measure of signal strength corresponding to each wireless device of the plurality of wireless devices;
• assign for each wireless device, downlink resource units within a first frequency band of the first channel to mitigate interference with a second frequency band of the second channel adjacent to the first channel by assigning downlink resource units within the first frequency band furthest from a center frequency of the second frequency band in descending order of the measure of signal strength such that a strongest wireless device with a highest corresponding measure of signal strength is assigned a first set of downlink resource units closest to the center frequency of the second frequency band;
• and
• cause the first wireless network interface unit to communicate with the plurality of wireless devices on the downlink resource units.

A system comprising:

• a wireless network controller configured to determine a first frequency band of a downlink channel in a wireless network and a second frequency band of an uplink channel in the wireless network, wherein the first frequency band is adjacent to the second frequency band;
• and
• an access point configured to:
• obtain a measure of signal strength corresponding to each wireless device of a plurality of wireless devices attached to the access point;
• assign for each wireless device, downlink resource units within the first frequency band of the downlink channel to mitigate interference with the second frequency band of the uplink channel by assigning downlink resource units within the first frequency band furthest from a center frequency of the second frequency band in descending order of the measure of signal strength such that a strongest wireless device with a highest corresponding measure of signal strength is assigned a first set of downlink resource units closest to the center frequency of the second frequency band;
• and
• communicate with the plurality of wireless devices on the downlink resource units.
