Abstract

A Personal Emergency Response System (PERS) includes a call device (10) with a call button (12), LAN (20), WAN (22), and locator service(s) (26, 42). The PERS further includes a hub or gateway device (30). The call device is programmed to periodically send transmissions to the hub or gateway device using the LAN, recognize based on the transmissions that the call device is no longer in a home geo-fence, and transition to communicating using the WAN in response to recognizing that the call device is no longer in the home geo-fence. The transition also includes turning on the locator service(s). The call button triggers the call device to contact the hub or gateway device using the LAN, or a PERS call center when using the WAN. A speaker (14) and microphone (16) are built into the call device for use when communicating using the WAN.
