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.

Abstract
Systems and methods for communicating with a radio frequency (RF) device are disclosed herein. In particular, a method of the present disclosure includes: listening for a first hailing signal to be received on at least one hailing channel selected from a plurality of hailing channels, selecting at least one hailing channel based upon a system time and a node identification; determining a noise floor for the at least one hailing channel; and upon receiving a noise signal on the at least one hailing channel, adjusting the noise floor in response to the noise signal.
