Abstract

A method of allocation transmission channels of a frequency band to has each of a plurality of remote stations monitor all channels of the frequency band in its area for the presence of transmissions from stations not part of the network. Each remote station transmits its clear channel list to a master station that aggregates the clear channel list into a reservation map, or map of channels that are clear to all stations in the network. The master station then transmits the reservation map to all stations of the network. The individual stations use the channels of the reservation map to transmit information to the master station. Preferably transmission is accomplished using frequency hopping using a set of channels selected from the reservation map.

Claims

1. In a network having at least one master station and a plurality of remote stations, a method of allocation of transmission channels of a frequency band, comprising the steps of:

a. receiving a list of clear channels from each of said plurality of remote stations;

b. aggregating said lists of clear channels into a reservation map comprising a master list of clear channels that are clear to all stations in said network;

c. sending said reservation map to said all stations in said network.

2. The method of claim 1, further comprising the step of using selected channels from said reservation map for transmission.

3. A master station for controlling a plurality of remote stations of a network, comprising:

a. a receiver for receiving lists of clear channels from each of said plurality of remote stations;

b. a processing element for aggregating said lists of clear channels into a reservation map comprising a master list of clear channels that are clear to all stations in said network; and

c. a transmitter for sending said reservation map to said all stations in said network.
