Abstract: In Situ Re-Configurable Wireless Communications System (IRCWCS) in combination with a wearable computer provides an individual user at a public gathering place, fixed facility or non-stationary object with new and enhanced capabilities. In one embodiment of the invention, the re-configurable wireless communication system includes a portable wireless access unit and a Long Range Ethernet (LRE) network switch that connects to an existing LAN. A bridge device such as an LRE puck connects the portable wireless access unit to the LRE network switch through a communications infrastructure. A wearable computer in wireless communication with the portable wireless access unit using a radio frequency link allows communication of video, voice and data to and from the existing LAN through the LRE network switch. The LRE network switch couples to a central command station through the existing LAN.
