Abstract: Transceivers, computer readable media, and methods for encoding wireless signals in a wireless signaling environment. A method includes the step of receiving, from a wireless system via at least one antenna, a wireless signal encoding data representative of a transmission code. In response to receiving the wireless signal, the method includes the step of processing the data representative of the transmission code. The method includes the step of generating a responsive wireless signal according to the transmission code, also in response to receiving the wireless signal. Further in response to receiving the wireless signal, the method includes the step of transmitting, via the at least one antenna, the responsive wireless signal to the wireless system to identify the transceiver to the wireless system in a wireless signaling environment.
