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.

1. An elevator monitoring system for monitoring the performance of elevators located within multiple buildings comprising: a first elevator located within a first building, said elevator in communication with a first building transceiver for receiving elevator performance data from said first elevator; a second elevator located within a second building, said second elevator in communication with a second building transceiver for receiving elevator performance data from said second elevator; a third elevator located within a third building, said third elevator in communication with a third building transceiver for receiving elevator performance data from said third elevator, and wherein said building transceivers are in wireless communication with at least one of the other building transceivers for transmitting and receiving elevator performance data; and a first central monitoring station in communication with said first building transceiver for receiving elevator performance data from said first, second and third elevators. 2. The elevator monitoring system of claim 1 wherein the first central monitoring station is in communication with said first and second building transceivers for receiving elevator performance data from said first, second and third elevators, wherein said first central monitoring station receives said performance data from said first, second, and third elevators in the event that communication between said first central monitoring station and one of said first and second transceivers is interrupted. 3. The elevator monitoring system of claim 1 wherein communication between said first elevator and said first transceiver is wireless. 4. The elevator monitoring system of claim 1 wherein communication between said first central monitoring station and said first building transceiver is wireless. 5. The elevator monitoring system of any one of claims 3 or 4 wherein the performance data is transmitted using frequency hopping spread spectrum technique. 6. The elevator monitoring system of claim 1 wherein communication between said first central monitoring station and said first building is through a phone line. 7. The elevator monitoring system of claim 1 further comprising a second central monitoring station in communication with said second building transceiver for receiving elevator performance data from said first, second and third elevators.
