Systems and methods for dynamic squelching in radio frequency devices

1. A radio frequency (RF) apparatus for sending and receiving wireless communications, the RF apparatus further comprising:

an oscillator;

a memory configured to store a hailing channel frequency set and a data channel frequency set, the hailing channel frequency set comprising a plurality of hailing channels and the data channel frequency set comprising a plurality of data channels;

an antenna operatively configured to send and receive RF communications; and

a microprocessor operatively connected to the oscillator, the memory and the antenna, the microprocessor comprising:

logic to listen for a first hailing signal to be received on at least one hailing channel selected from the hailing channel frequency set, selecting the at least one hailing channel based upon a system time and a node identification;

logic to determine a noise floor for the at least one hailing channel;

logic to receive a noise signal on the at least one hailing channel; and

logic to adjust the noise floor in response to the noise signal.

2. The RF apparatus of claim 1 , wherein the noise floor is based on a signal strength indicator.

3. The RF apparatus of claim 2 , wherein the signal strength indicator is an indication of the amount of energy present in the at least one hailing channel.

4. The RF apparatus of claim 1 , wherein the logic to adjust the noise floor comprises:

logic to raise the noise floor to maintain a predefined false break ratio.

5. The RF apparatus of claim 4 , wherein the false break ratio is approximately 800 false breaks per day.

6. The RF apparatus of claim 1 , wherein the logic to adjust the noise floor comprises:

logic to lower the noise floor to maintain a predefined false break ratio.

7. The RF apparatus of claim 6 , wherein the false break ratio is approximately 800 false breaks per day.
