Abstract
The subject matter described herein relates to light based positioning. In one embodiment, a method comprises: responsive to receiving a light signal from at least one light source available to the device, decoding a beacon from the received light signal, the beacon associated with the at least one light source; measuring signal strength of the received light signal; and determining a position of the device at least in part based on the decoded beacon, the measured signal strength, and number of the at least one light source. In addition, the frequency channelization and random channel hopping may be utilized to further improve the performance.
