Abstract: In one preferred embodiment, a set of air interface protocols (AIPs) provides a method for secure wireless-to-IP communication between conveyance-mounted security sensors and one or more remote data consolidation centers employing a global ad-hoc network topology, comprising one or more on-conveyance sensing devices; one or more on-conveyance wireless communications devices; one or more wireless-to-IP bridging devices; one or more internet-addressable remote data centers; wherein the remote data center contains computer instructions for: commanding secure AIP-compliant operations; and maintaining a data base of security sensor-related events interfacing to an encryption key management facility.

Abstract: In one embodiment, a wireless bridge for wireless to TCP/IP based communication is provided. The wireless bridge can be with reduced functional devices (RFDs) in a star topology network acting as a network access device (NAD). Another embodiment can be with fully functional devices (FFDs) in a peer-to-peer topology network also capable of operating as a NAD. The network address device includes a processor with memory; a radio frequency transceiver front end communicating with the processor; an antenna coupled to the front end; and a power source providing power to the processor and front end wherein the processor with memory contains computer instructions for executing IEEE 802.15.
