    Abstract: An elevator system includes an elevator car (28) disposed in and constructed and arranged to move along a hoistway (26) generally defined by a stationary structure. A short-range communication system of the elevator system is configured to provide communication between the elevator car and the stationary structure, and may include a transceiver (62, 64) carried by the elevator car and a plurality of transceivers (66) spaced along the hoistway. A network coordinator (68) of the communication system is operatively coupled to the plurality of hoistway transceivers to provide uninterrupted communication.
