Anonymous Reader writes “DeviceForge has published an Intel-authored whitepaper introducing an open source toolkit that lets mobile devices determine their locations with the aid of freely accessible, nearby radio sources, such as fixed Bluetooth devices, 802.11 access points, and GSM cell towers. Basically, the device reads the IDs of these local “radio beacons” (each of which has a unique or semi-unique ID), looks up their positions in a locally-cached database, and performs a computation akin to triangulation.”
