providing a plurality of beacon devices at different locations within said space; and
transmitting a beacon signal from each of the beacon devices, each beacon signal having a unique information component and a unique frequency pattern of multiple frequencies, wherein no frequency of the unique frequency pattern is an even harmonic of any other frequency of the unique frequency pattern, each beacon signal being distinguishable from the beacon signals transmitted from any other of the beacon devices based on a combination of its unique information component and its unique frequency pattern; and
wherein each beacon signal is generated by filtering a raw information component by the frequencies of the unique frequency pattern of the beacon signal.
