Intelligent selection of operating parameters for a wireless access point
Aspects of the disclosure are directed toward intelligently selecting the operating parameters of wireless access points (WAPs) deployed in a wireless environment so as to minimize or at least reduce interference in that wireless environment. A WAP may continually measure characteristics of wireless channels used in the wireless environment and obtain measurements of channel metrics for those channels. The WAP analyzes the channel metric history to identify correlations between the channel metric measurements and various timeframes and selects one or more of its operating parameters based on the channel metric history and the correlations identified.
1. A method comprising:
receiving a plurality of metrics for a plurality of channels of a radio frequency band;
determining that a difference between a first average, of the plurality of metrics and associated with a first timeframe, and a second average, of the plurality of metrics and associated with a second timeframe, is equal to or greater than a threshold amount, wherein the first timeframe is different from the second timeframe;
adjusting, by a wireless access point and based on the determining, an operating parameter of the wireless access point; and
sending wireless communications using the adjusted operating parameter.
2. The method of claim 1 , wherein:
adjusting the operating parameter comprises adjusting one or more of the radio frequency band, a channel within the radio frequency band, a wireless networking standard for the wireless access point, or a transmit power.
3. The method of claim 1 , further comprising:
storing the plurality of metrics in a history of channel metric measurements, wherein the first timeframe and the second timeframe are consecutive timeframes.
4. The method of claim 1 , further comprising:
reassigning, by the wireless access point and based on a history of use of a first channel of the plurality of channels, a connected device from the first channel to a second channel of the plurality of channels.
5. The method of claim 1 , further comprising:
storing information indicating a usage level of a first channel for different times of day.
6. The method of claim 1 , wherein:
receiving the plurality of metrics comprises receiving the plurality of metrics at periodic intervals.
7. The method of claim 1 , wherein:
receiving the plurality of metrics comprises receiving a metric for each channel of each radio frequency band the wireless access point is configured to utilize.
8. The method of claim 1 , wherein:
the plurality of metrics comprises one or more of:
a measurement of traffic on each channel of the plurality of channels of the radio frequency band,
a total quantity of wireless access points utilizing each channel of the plurality of channels of the radio frequency band,
a bandwidth utilization of each channel of the plurality of channels of the radio frequency band, or
a transmit opportunity on each channel of the plurality of channels of the radio frequency band.
9. The method of claim 1 , further comprising:
sending the plurality of metrics to a computing device located remotely from the wireless access point.
10. The method of claim 1 , further comprising:
disabling, based on a connected device receiving streaming traffic via an operating channel of the plurality of channels, adjustment of an operating channel.
11. The method of claim 1 , wherein the operating parameter comprises an operating channel and the method further comprises:
scheduling selection of the operating channel based on a pattern of channel use identified from historical metric values.
12. The method of claim 1 , wherein the first average comprises an average of a subset of the plurality of metrics, associated with a first timeframe; and the second average comprises an average of the subset of the plurality of metrics, associated with a second timeframe.
13. The method of claim 1 , further comprising:
storing information indicating a usage level of a first channel, of the plurality of channels, for different times of day; and
adjusting, by the wireless access point and based on the information, an operating parameter of the wireless access point.
