US Patent 10433189 Flexible radio assignment

A flexible radio assignment algorithm that reduces co-channel interference in Wi-Fi networks is disclosed. The flexible radio assignment algorithm calculates a density value for each of the APs controlled by a network controller. The flexible radio assignment algorithm selects an AP with the highest density value and determines that a radio in the selected AP is redundant. The flexible radio assignment algorithm manages the redundant radio in the selected AP to mitigate co-channel interference in a frequency band.
