Frequency self-organizing radio network system and method
First Claim
1. A method of modifying a carrier sense multiple access (CSMA) protocol used in a node in a first group of one or more radio nodes each using the CSMA protocol to avoid interference to or from a second group of radio nodes which do not use the CSMA protocol, the method comprising:
- listening in a listening period on a first frequency band for transmission traffic by neighboring radio nodes using the CSMA protocol; and
identifying, during the listening period, radio traffic on the first frequency band from the second group of radio nodes which do not use the CSMA protocol.

Abstract
A system and method of determining an available frequency sub-band for radio traffic in a multiple node radio network is disclosed. The method and system provide for communication over a radio frequency band, the radio frequency band comprising radio frequency sub-bands and providing a radio node group of at least one radio communications devices configured to broadcast and receive on the radio frequency band. The system and method create a time for a window of radio broadcast silence on at least one of the radio frequency sub-bands by the radio node group. The system and method survey the at least one of the radio frequency sub-bands during the window of radio broadcast silence. The system and method choose, based on the survey, a radio frequency sub-band for broadcast from the radio frequency band.
