Abstract (en)
[origin: WO0158098A2] Apparatus and method to determine the position of a wireless device with Bluetooth capabilities. The method relies on transferring positioning information between devices using Bluetooth technology. If one of these devices knows its position (because it is in fixed position or because it has a GPS receiver or GPS sensor, or other ways of determining its own position), then this positioning information can be transferred to other devices in the RF proximity. In addition, triangulation using range measurements, and/or signal strength from several devices in the RF proximity can be used to determine the device position.
