Radio frequency localization

A system for monitoring a plurality of transceivers located in an area to be monitored, the system comprising:

• means for enabling one transceiver of the plurality of transceivers and disabling all other transceivers of the plurality of transceivers;
• a plurality of transmit coils emitting high frequency electromagnetic fields, the plurality of transmit coils being suitably arranged in the vicinity of the area to be monitored, the one transceiver transmitting signals in response to the fields of the plurality of transmit coils;
• a reader having at least one reader coil for receiving the signals transmitted by the one transceiver;
• and
• an evaluator for determining a position of the one transceiver from the signals received from the one transceiver by the at least one reader coil.

A method for monitoring a plurality of transceivers located in an area to be monitored, the method comprising the steps of:

• enabling one transceiver of the plurality of transceivers;
• disabling all other transceivers of the plurality of transceivers;
• a transmit coil emitting a high frequency electromagnetic field, the one transceiver transmitting a signal in response to the field of the transmit coil;
• at least one of a plurality of reader coils receiving the signal transmitted by the one transceiver, the plurality of reader coils being suitably arranged in the vicinity of the area to be monitored;
• and
• an evaluator determining a position of the one transceiver from the signal received from the one transceiver by the at least one of the plurality of reader coils.
