Abstract

Systems and methods for facilitating power control in an access point are provided. Disclosed embodiments include detecting the presence of a neighboring access point that is within radio reach of the access point. A signal strength corresponding to the neighboring access point is ascertained such that the neighboring signal strength is a function of the transmission power of the neighboring access point. The transmission power of the access point is then varied as a function of the neighboring signal strength.
