SYSTEM AND METHOD FOR RESILIENT COVERAGE IN A WIRELESS ENVIRONMENT
摘要
Described is a system and method for resilient coverage in a wireless environment. The system may include a first wireless device (110) having a first wireless transceiver; a second wireless device (125) having a second wireless transceiver; and an envelope detection arrangement ("EDA") (540) coupled to the second wireless device. The second wireless device has a first communication mode and a second communication mode. The second wireless transceiver conducts wireless communications with the first wireless transceiver using a predetermined wireless communication protocol (e.g., IEEE 802.11/16) only when the second wireless device is in the first communication mode. The second wireless transceiver is in a low-power state when in the second communication mode. The EDA screens radio frequency signals for a signal having a predetermined envelope sequence; the signal is generated according to the same predetermined wireless communication protocol. When the EDA receives the signal, the arrangement causes the second wireless device to switch into the first communication mode.
