Abstract
In one embodiment, location aware operation is provided using Bluetooth positioning. A Bluetooth-enabled handheld device is operated within a structure. Received Bluetooth signal strengths are measured for a plurality of Bluetooth-enabled transmitter/receiver units dispersed within the structure, where respective ones of the plurality of Bluetooth-enabled transmitter/receiver units are located on separate floors, in separate rooms, or in different portions of a same room. Based on the received Bluetooth signal strengths, a single Bluetooth-enabled transmitter/receiver unit is selected. A location of the selected Bluetooth-enabled transmitter/receiver unit is assigned to the Bluetooth-enabled handheld device. A first electronic device is controlled based on the assigned location. In response to movement by a user of the Bluetooth-enabled handheld device within the structure, a location of a different Bluetooth-enabled transmitter/receiver unit is reassigned to the Bluetooth-enabled handheld device. A second electronic device is controlled based on the reassigned location.
