Abstract

See full text

In one embodiment, a device in a network receives a radio frequency (RF) beacon. The device determines a received signal strength indication (RSSI) of the received RF beacon. The device compares the determined RSSI to an RSSI threshold. The device sends a burst of ultrasound or infrared beacons when the determined RSSI of the RF beacon exceeds the RSSI threshold. The burst of ultrasound or infrared beacons is then used by a location service in the network to determine a physical location of the device.
