1. A method for dynamically configuring a deployed wireless access point (AP) by flexible radio assignment of varying cell sizes and frequency bands, the method performed by a processor of a network controller and comprising:
determining a frequency band of the deployed wireless AP;
determining that a threshold number of client devices are in a wireless coverage area of the deployed wireless AP on the frequency band;
determining a proximity, to the deployed wireless AP, of two or more of the client devices;
determining, based at least in part on the proximity, a first number of the two or more client devices that could be served by a first radio of the deployed wireless AP operating to provide wireless coverage in the wireless coverage area and a second number of the two or more client devices that could be served by a second radio of the deployed wireless AP operating at a reduced transmit power level as compared to the first radio;
determining that the second number of the two or more client devices that could be served by the second radio is less than a preset value;
computing available channel choices for the first radio and the second radio;
determining that a number of the available channel choices for the first radio and the second radio exceeds a threshold number of channels; and
selecting, in response to the number of available channel choices exceeding the threshold number of channels, a band-locked configuration for the first radio and the second radio.
 
10. A system for dynamically configuring a deployed wireless access point (AP) by flexible radio assignment of varying cell sizes and frequency bands, the system comprising:
a network controller comprising one or more processors; and
memory storing computer-executable instructions, that, when executed by the one or more processors, cause the network controller to:
determine a frequency band of the deployed wireless AP;
determine that a threshold number of client devices are in a wireless coverage area of the deployed wireless AP on the frequency band;
determine a proximity, to the deployed wireless AP, of two or more of the client devices;
determine, based at least in part on the proximity, a first number of the two or more client devices that could be served by a first radio of the deployed wireless AP operating to provide wireless coverage in the wireless coverage area and a second number of the two or more client devices that could be served by a second radio of the deployed wireless AP operating at a reduced transmit power level as compared to the first radio;
determine that the second number of the two or more client devices that could be served by the second radio is less than a preset value;
compute available channel choices for the first radio and the second radio;
determine that a number of the available channel choices exceeds a threshold number of channels; and
select, in response to the number of available channel choices exceeding the threshold number of channels, a band-locked configuration for the first radio and the second radio.
 
19. A non-transitory computer-readable medium for dynamically configuring a deployed wireless access point (AP) by flexible radio assignment of varying cell sizes and frequency bands, the non-transitory computer-readable medium storing instructions, that, when executed by one or more processors of a network controller, cause the network controller to:
determine a frequency band of the deployed wireless AP;
determine that a threshold number of client devices are in a wireless coverage area of the deployed wireless AP on the frequency band;
determine a proximity, to the deployed wireless AP, of two or more of the client devices;
determine, based at least in part on the proximity, a first number of the two or more client devices that could be served by a first radio of the deployed wireless AP operating to provide wireless coverage in the wireless coverage area and a second number of the two or more client devices that could be served by a second radio of the deployed wireless AP operating at a reduced transmit power level as compared to the first radio;
determine that the second number of the two or more client devices that could be served by the second radio is less than a preset value;
compute available channel choices using regulator and interference factors;
determine that a number of the available channel choices exceeds a threshold number of channels; and
select, in response to the number of available channel choices exceeding the threshold number of channels, a band-locked configuration for the first radio and the second radio.
