Method and system for dynamically assigning channels across multiple radios in a wireless LAN

摘要

According to one embodiment, a method includes monitoring, at one or more wireless network access elements, signal strength of signals transmitted by respective neighboring wireless network access elements. Information is collected from said wireless network access elements and converted into reportable data about signal strength observed during the monitoring. The method further includes identifying, based at least in part on interference associated with concurrent signal transmissions of the wireless network access elements, a combination of channel assignments for the one or more wireless network access elements from a plurality of possible combinations of channel assignments and assigning channels for concurrent, respective use by said wireless network access elements based on the identified combination of channel assignments.

1. A method, comprising:
monitoring, at one or more wireless network access elements, signal strength of signals transmitted by respective neighboring wireless network access elements; collecting information from said wireless network access elements and converting said information into reportable data about signal strength observed during the monitoring the signal strength of signals by the one or more wireless network access elements and about access element load, wherein the reportable data about access element load comprises:
data regarding wireless network traffic load corresponding to each of said wireless network access elements over a period of time; andphysical interference; creating a signal strength matrix describing the signal strength observed between each of the access elements; creating a utilization matrix describing the load observed at each access element over a given time interval; combining the signal strength matrix and the utilization matrix to create an average signal strength matrix describing the average signal strength observed between each of the access elements; creating a first interference matrix by matrix-multiplying the average signal strength matrix by a channel assignment matrix describing a plurality of possible combinations of channel assignments of the physical channels across the access elements; and identifying, based at least in part, on said physical interference associated with concurrent signal transmissions of the wireless network access elements, a combination of channel assignments for the one or more wireless network access elements from the plurality of possible combinations of channel assignments and assigning channels for concurrent, respective use by said wireless network access elements based on the identified combination of channel assignments.
