System, apparatus and method to control output of radio frequency signal
First Claim
1. A method of controlling an output of a radio frequency signal in a wireless local area network (LAN) environment having an infrastructure, comprising:
- allowing an access point to sense a radio frequency signal in a predetermined frequency band; and
transmitting predetermined event information to a network connected to the access point when the radio frequency signal is sensed by transmitting a frame containing output control information on the output of a radio frequency signal,wherein the output control information comprises information used to disable the output of a radio frequency signal.

Abstract
A system, apparatus and method to control the output of a radio frequency signal in a wireless local area network (LAN) system having an infrastructure. The system includes an access point which periodically transmits a frame including output control information used to control the output of the radio frequency signal, and a wireless terminal apparatus including a wireless transceiver module which receives the frame and a control module which extracts the output control information from the received frame, and controls the output of the radio frequency signal by the wireless transceiver module according to the extracted output control information.
