Apparatus for interconnecting wireless networks separated by a barrier
WO 2011109070 A3
Abstract
An apparatus for bridging a barrier to wireless communication between wireless field device networks includes a pair of locally-powered wireless devices connected by a wired link spanning the barrier. At least one of the locally-powered wireless devices is in wireless communication with each of the wireless networks intended to be interconnected. The wireless devices include a wireless transceiver and an antenna. Messages from one wireless field device network addressed to a member node of another wireless field device network are received by a wireless device on one side of the barrier and transmitted via the wired link to another wireless device on the other side of the barrier for routing to the member node of the other wireless field device network.
