Tone frequency signaling
First Claim
1. A transceiver comprising:
- a transmitter to transmit a first signal, the first signal comprising a first data signal modulated onto a first carrier tone;
a receiver to receive a second signal and monitor a characteristic of the second signal, the second signal comprising a second data signal modulated onto a second carrier tone; and
a controller coupled to the transmitter and the receiver to change the frequency of the first carrier tone from a first frequency to a second frequency in response to the monitored characteristic of the second signal.

Abstract
This application disclosed an apparatus and process for tone frequency signaling. The apparatus comprises a transmitter to transmit a first signal, the first signal comprising a first data signal modulated onto a first carrier tone, a receiver to receive a second signal and monitor a characteristic of the second signal, the second signal comprising a second data signal modulated onto a second carrier tone, and a controller coupled to the transmitter and the receiver to change the frequency of the first carrier tone from a first frequency to a second frequency in response to the monitored characteristic of the second signal. The process comprises transmitting a first signal, the first signal comprising a first data signal modulated onto a first carrier tone, receiving a second signal, the second signal comprising a second data signal modulated onto a second carrier tone, monitoring a characteristic of the second signal, and changing the frequency of the first carrier tone from a first frequency to a second frequency in response to changes in the monitored characteristic of the second signal. Other embodiments are described and claimed.
