12. A method for communicating with a radio frequency (RF) device, the method comprising:
-
listening for at least a first hailing signal to be received on at least a first at least one hailing channel selected from a plurality of hailing channels, selection of the at least one hailing channel depending on a system time and a node identification; and in response to listening for the at least first hailing signal and not receiving the at least first hailing signal on the first at least one hailing channel, entering a sleep mode during which no listening occurs for a period of time. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for communicating between a parent radio frequency (RF) device and a child RF device, the method comprising:
-
transmitting for a period of transmitting time by the parent RF device a hailing signal on at least one hailing channel selected from a plurality of hailing channels, wherein the selected at least one hailing channel depends on a system time known to both the parent RF device and the child RF device; sampling by the child RF device for the hailing signal for a period of sampling time; in response to the child RF device hearing the hailing signal during the sampling time, switching from a hailing mode to a data mode; and in response to the child RF device not hearing the hailing signal during the sampling time, switching from the hailing mode to a sleep mode. - View Dependent Claims (20, 21, 22)

23. 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 connected to the microprocessor and being 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 determine a system time based on the oscillator; logic to transmit and receive via the antenna a hailing signal on at least one of the plurality of hailing channels; logic to transmit and receive via the antenna data on at least one of the plurality of data channels. - View Dependent Claims (24, 25, 26, 27)
