Abstract
An electronic label apparatus comprises: an inductive communication unit which communicates wirelessly using inductive signals; a processor; memory including a computer program code; and a power source which supplies electric power to the inductive communication unit, the processor, and the memory for enabling their operation. The processor, the memory, the computer program code and the power source with the electric power cause the electronic label apparatus at least to: receive a plurality of inductive signals of known transmission powers from known locations; measure signal powers of the received inductive signals; and determine information about a location of the electronic label apparatus based on the measured signal powers, the known transmission signal powers and the known locations.
