Wireless information communicating terminal and device for its updating

A wireless information communicating terminal comprising a member externally providing first information, a first receiver of Ultra-Wide Band type able to receive a first signal containing first data on a first determined wireless communication channel of Ultra-Wide Band type, a control unit to generate the first information to be sent to the member as a function of the first data received by the first receiver,

• the wireless information communicating terminal further comprising at least one second transmitter able to transmit a second signal on a second determined wireless communication channel of Ultra-Wide Band type,
• the control unit being configured to cause the transmission of the second signal by the second transmitter in response to receiving of the first signal by the first receiver,
• wherein the wireless information communicating terminal further comprises a third receiver to receive a third trigger signal on a third wireless communication channel, the control unit being configured in response to receipt of the third trigger signal by the third receiver to set in operation the first receiver of Ultra-Wide Band type for a predetermined time so that the first receiver of Ultra-Wide Band receives the first signal containing first data on the first determined wireless communication channel of Ultra-Wide Band type,
• the third communication channel differing from the first communication channel at least in that the third receiver, for same setting in operation time, has lower power consumption than the first receiver.
