US Patent 7596461 Measurement of air quality in wireless networks

A system for measuring air quality in wireless networks. In particular implementations, a method includes computing an interference severity level for a plurality of interference sources detected at an access point; aggregating one or more of the computed interference severity levels relative to the access point; and computing an air quality metric for the access point, wherein the air quality metric based at least in part on an equation: 1—aggregated interference severity level.
