Patent ID: 8885688

Claim:
A repeater for use in a wireless local area network, comprising: a transceiver for receiving a signal on a first frequency channel and for transmitting the signal on a second frequency channel different from the first frequency channel; and a control message modulator/demodulator (MODEM) coupled to the transceiver for demodulating a receive control message packet on the first frequency channel and for modulating one or more transmit control message packets that are transmitted by the transceiver on the first frequency channel in response to the receive control message packet, wherein the one or more transmit control message packets each include a first portion that corresponds to an unmodified version of the receive control message packet and a second portion that is modified from a corresponding portion of the receive control message packet by deliberately introducing error so as to reduce a likelihood that the one or more transmit control message packets will be successfully decoded at a receiver.
