The present invention is directed to a tracking device, system and method that may utilize GPS, global system for mobile communications (GSM) or general packet radio service (GPRS), including using triangulation, and/or wireless local area network (WLAN) technologies to improve the scope, range, reliability, convenience and speed of current tracking devices. The present invention may employ a wearable or attachable device to track persons, such as children or the elderly, or objects, for example. The wearable device may be designed to be secured to the wearer to track the wearer's whereabouts. Unauthorized removal, destruction, or tampering of the tracking device may result in alerts being sent out to a variety of monitoring stations. The tracking and alerts, for example, may be monitored via a convenient remote monitoring interface. |
