Abstract

The invention provides a wireless automatic location identification (ALI) capable system (10), including a medical device (12) having a wireless data communicator (14), a wireless communication network (16), and a remote locating service (18) for remotely locating and monitoring one or more medical devices over the wireless communication network. When the medical device is linked to the remote locating service over the communication network, the ALI-capable system identifies the location of the medical device and relays the location information to the remote locating service. The system permits reliable determination of the location of the medical device wherever the medical device is situated. The medical device may further be configured to transmit signals indicative of its status, condition, or self-test results, to the remote locating service. This feature allows the remote locating service to centrally monitor the status or condition of a plurality of medical devices.
