ABSTRACT:
Access to a wireless data network to nodes located in a defined operational area is limited by transmitting a network signal within the defined operational area while transmitting a wave that can cause destructive interference with the network signal into a prohibited area adjacent to the defined operational area. The wave that can cause destructive interference is produced by phase and/or amplitude modulating the network signal. The modulation of the network signal includes sweeping the phase and/or amplitude.
