ABSTRACT:
The invention optimizes the security of data communication on wireless local area networks (WLANs). This invention uses radio frequency (RF) radiation sensors (sensors) on the physical perimeter of a campus, or between nodes in a wireless mesh network, to detect signal bleed outside of an acceptable geographic range. In a preferred embodiment, this is achieved by (1) setting the acceptable signal strength (“bleed”) to be allowed at the perimeter, (2) sensing the RF signal strength at the perimeter sensors, (3) providing feedback from the sensors to the central radiation source controller (controller), (4) adjusting the central radiation source signal strength upwards or downwards based on acceptable ranges, (5) repeating this procedure in real time to provide constant optimization.
