1. A radio frequency (RF) apparatus for sending and receiving wireless communications, the RF apparatus comprising:
- an oscillator;
a memory storing 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 connected to the microprocessor; and
a microprocessor operatively connected to the oscillator, the memory and the antenna, the microprocessor configured to;
determine a system time based on the oscillator;
transmit and receive via the antenna a hailing signal on at least one of the plurality of hailing channels;
transmit and receive via the antenna data on at least one of the plurality of data channels.
