Abstract: A system is provided for communication and sensory monitoring. The system comprises a plurality of nodes installed as a network in a structure. Each of the plurality of nodes comprises an internode transceiver for wireless communication between nodes, a wireless network transceiver for wireless communication with one or more wireless devices, one or more sensors for monitoring the environment of the structure and a processor coupled to the internode transceiver, the wireless network transceiver and the one or more sensors to exchange data with the internode transceiver, the wireless network transceiver and the one or more sensors devices coupled to the processor and process the data. The system also includes a wide area network bridge coupled to the plurality of network nodes. The network bridge receives data from the plurality of network nodes and passes the information to a computer network for processing.

Abstract: The location of unmodified wireless assets in a wireless communication network may be identified using time differences of arrivals of a communication sequence at different network receivers. Time-stamping devices may include correlator circuits in parallel with signal decoders to time-stamp communication sequences. Cellular wireless networks may be frequency-multiplexed to increase spatial time-stamping density. Tags may be attached to passive assets to provide location identification information to network devices. Locations of assets broadcasting standard 802.11 radio frequency structures may be identified. Noise inherent in correlating a communication sequence may be reduced by using a selected correlation function.
