## Abstract

A protocol for initiating communications between STAR devices in a network includes communicating via a communication device having a transmit signal path and a receive signal path where the transmit signal path and receive signal path are operable to transmit and receive simultaneously at the same frequency over an interference-suppressed band. A communication sub-band and an initiation sub-band are generated within the interference-suppressed band. The initiation sub-band has a lower bandwidth than the communication sub-band. Signals may be transmitted and received signals over the initiation sub-band the communication sub-band.

## Claims

### Claim 1

A communication method comprising facilitating a communication network between a plurality of communication devices having a transmit signal path and a receive signal path, the transmit signal path and receive signal path being operable to simultaneously transmit and receive at the same frequency over an interference-suppressed band, by:
generating a communication sub-band and an initiation sub-band within the interference-suppressed band, the initiation sub-band having a lower bandwidth than the communication sub-band;
executing a polling stage in which a first communication device transmits a polling signal within the initiation sub-band to a second communication device;
executing an interrogation stage in which the first communication device transmits an interrogation signal within the initiation sub-band to the second communication device;
executing an authenticating stage in which the first communication device transmits a timing signal to the second communication device; and
executing a communication stage based on the timing signal in which the first and second communication devices communicate by transmitting and receiving simultaneously at the same frequency within the communication sub-band.

### Claim 2 (depends on 1)

The communication method of claim 1, further comprising forming the interference-suppressed band by suppressing interference between the transmit signal path and receive signal path.

### Claim 3 (depends on 1)

The communication method of claim 1, wherein the initiation sub-band operates at a lower power than the communications sub-band.

### Claim 4 (depends on 1)

The communication method of claim 1, wherein the communication sub-band is at least 75% of a bandwidth of the interference-suppressed band.

### Claim 5 (depends on 1)

The communication method of claim 1, wherein the initiation sub-band includes a first frequency range higher than the communication sub-band and a second frequency range lower than the communication sub-band.

### Claim 6 (depends on 1)

The communication method of claim 1, further comprising, simultaneously at the same frequency in the initiation sub-band, transmitting a polling signal by the first communication device and receiving by the first communication device a polling signal from the second communication device.

### Claim 7 (depends on 1)

The communication method of claim 1, wherein processing circuitry is configured to transmit and receive over the communication sub-band simultaneously at the same frequency.

### Claim 8 (depends on 1)

The communication method of claim 1, wherein signals transmitted in the initiation sub-band are lower power than a baseline power of the communication sub-band.
