Patent ID: 7948914

Claim:
A method of learned power security for a wireless network, the method comprising the steps of: transmitting, by a base station, a signal to one or more remote devices at corresponding locations ill an area; measuring, by the remote device at each location ill the area, a received signal strength of the signal transmitted by the base station, wherein each location is substantially near all outer boundary of the area; communicating to the base station, by the remote device, the received signal strength at the corresponding location of the remote device; and defining an authentication perimeter for the area by: (i) setting a transmit signal power of the base station based on the received signal strength at each location, and (ii) configuring one or more antenna characteristics of the base station to define the authentication perimeter, wherein configuring the one or more antenna characteristics modifies a coverage of the base station such that a first transmit signal power level is present at a location of a first remote device, and a second transmit signal power level is present at a location of a second remote device; iteratively repeating the transmitting, measuring, and communicating steps until the transmit signal power of the base station reaches a threshold, thereby defining the authentication perimeter; estimating, for each corresponding location of the one or more remote devices, a distance between the base station and the location; and generating a map of the authentication perimeter defined by the one or more distances between the base station and the corresponding locations of the one or more remote devices.
