Abstract
A wireless communications system for use with an elevator system in a building includes a first transceiver connected to an elevator controller and a second transceiver located remotely within the building. The first and second transceivers each have antennas which allow wireless transmission of data between the transceivers. A building monitoring center is hard-wired to the second transceiver to allow personnel to monitor and interact with each elevator controller. A third transceiver and antenna are located outside of the building and are connected to a central monitoring station to allow remote monitoring and interaction with each elevator controller. The wireless communications system can be used with a network of elevators where each elevator has a unique electronic address to allow discreet wireless communications with a specific elevator.
