Abstract
A radio frequency identification (RFID) integrated circuit includes a transceiver and a processing device. The transceiver may to transmit a first continuous wave radio frequency (RF) signal to a bridge in a no-wire format via an antenna, where the transceiver is to start transmitting the modulated or continuous wave RF signal at a first amplitude value and increase an amplitude of the modulated or continuous wave RF signal to a second amplitude value at which an acknowledge (ACK) pulse is detected. The transceiver may receive a reflected wave RF signal in the no-wire format. The processing device may detect the ACK pulse in the reflected wave RF signal. The processing device may transmit a second modulated or continuous wave RF signal to the transceiver in the no-wire format.
