摘要：
A location detection system for person support apparatuses includes multiple network wireless access points that communicate with a plurality of mobile transceivers positioned on board the person support apparatuses. Based upon signal strength data (e.g. RSSI or RCPI) of messages from the access points to the transceivers, the locations of the person support apparatuses are determined. In some embodiments, the person support apparatuses include an additional location detection system that utilizes fixed locators having short range transceivers to generate a second location determination of the person support apparatuses. In still other embodiments, the person support apparatuses utilize the second location detection system to determine the location of the wireless access points. The person support apparatuses may also broadcast their location to other devices that then utilize the received signal strengths of those messages to determine their own location.
