Abstract
In described embodiments, elements of a wireless home network employ learned power security for the network. An access point, router, or other wireless base station emits and receives signals having corresponding signal strengths. Wireless devices coupled to the base station through a radio link are moved through the home network at boundary points of the home and the signal strength is measured at each device and communicated to the base station. Based on the signal strength information from the emitted signals measured at the boundary points and/or from measured signal strength information of signals received from the boundary points, the base station determines a network secure area. The base station declines permission of devices attempting to use or join the home network that exhibit signal strength characteristics less than boundary values for the network secure area.
