Abstract
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.
Claims20
A network controller, comprising:
- a processor;
- a memory containing a program that, when executed on the processor, performs an operation, the operation comprising:
- for each of a plurality of access points, calculating a respective density value indicating respective neighboring access points that are in direct communication with the access point;
- selecting an access point from the plurality of access points based on the respective densities values;
- calculating locations of the respective neighboring access points relative to the selected access point;
- determining that a radio in the selected access point is redundant based on the calculated locations;
- and
- managing the radio in the selected access point to mitigate co-channel interference in a frequency band after determining that the radio is redundant.
A computer program product, comprising:
- a non-transitory computer-readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to, for each of a plurality of access points, calculate a respective density value indicating respective neighboring access points that are in direct communication with the access point;
- computer readable program code configured to select an access point from the plurality of access points based on the respective densities values;
- computer readable program code configured to calculate locations of the respective neighboring access points relative to the selected access point;
- computer readable program code configured to determine that a radio in the selected access point is redundant based on the calculated locations;
- and
- computer readable program code configured to manage the radio in the selected access point to mitigate co-channel interference in a frequency band after determining that the radio is redundant.
A method, comprising:
- for each of a plurality of access points, calculating a respective density value indicating respective neighboring access points that are in direct communication with the access point;
- selecting an access point from the plurality of access points based on the respective densities values;
- calculating locations of the respective neighboring access points relative to the selected access point;
- determining that a radio in the selected access point is redundant based on the calculated locations;
- and
- managing the radio in the selected access point to mitigate co-channel interference in a frequency band after determining that the radio is redundant.
