Communication between electromagnetic transponders
Abstract
The invention relates to an electromagnetic transponder for taking the energy necessary for its operation from a field radiated by a transmission terminal of a carrier at a first remote power supply frequency and to retromodulate the signal received at the rate of a subcarrier. carrier-carrier at a second frequency lower than the first, and comprising means (28) adapted to demodulate and decode signals modulated by said sub-carrier, and a communication system between such transponders.
