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.

An elevator system, comprising:
- an elevator car disposed in and constructed and arranged to move along a hoistway generally defined by a stationary structure;
- and
- a short-range communication system configured to provide communication between the elevator car and the stationary structure, the short-range communication system including a first car transceiver carried by the elevator car, a plurality of hoistway transceivers spaced along the hoistway, and a first network coordinator operatively coupled to the plurality of hoistway transceivers to provide un-interrupted communication.
A rope-less elevator system comprising:
- an elevator car disposed in and constructed and arranged to move along a hoistway generally defined by a stationary structure;
- and
- a short-range communication system configured to provide communication between the elevator car and the stationary structure, the short-range communication system including a first car transceiver and a second car transceiver spaced below the first car transceiver and carried by the elevator car, a plurality of hoistway transceivers spaced along the hoistway, a first network coordinator operatively coupled to the plurality of hoistway transceivers and carried by the stationary structure to facilitate un-interrupted communication, and a second network coordinator operatively coupled to the first and second car transceivers and carried by the elevator car to facilitate un-interrupted communication.
