Abstract:
A mobile terminal includes a passive wireless receiver and a wireless transceiver. The passive wireless receiver receives a first activation signal from another mobile terminal, and transmits a second activation signal using power from the first activation signal. The wireless transceiver receives the second activation signal, and establishes a wireless connection with the other mobile terminal in response to receiving the second activation signal.
