1. A method of operation of a dynamic spectrum access (DSA) device, said method comprising:
- while operating in a first mode, selecting an initial startup operating channel frequency of the dynamic spectrum access device;
subsequent to selecting the initial startup operating channel frequency, entering a channel maintenance mode in which a plurality of communications are exchanged between the DSA device and at least one remote DSA device, at least one of the plurality of communications comprising an indication of the radio frequency environment in the region of a device sending the communication;
subsequent to selecting the initial startup operating channel frequency;
detecting a non-cooperative radio operating on the initial startup operating channel frequency; and
responsive to detecting the non-cooperative radio operating on the initial startup operating frequency, entering a channel switching mode in which a new operating channel frequency is selected for use by the DSA device based at least in part upon the indication of the radio frequency environment.

Abstract
Systems and methods for configuring a network of radios for dynamic spectrum access are described. A network radio can include hardware and/or software modules for detecting a radio environment and negotiating common communications channels with a plurality of other radios in the network. Network radio behavior can be defined by a plurality of predefined policies which are used in combination with the information about the radio environment to select common operating parameters.

14. A DSA system comprising:
-
a first DSA device; and a second DSA device; wherein the first DSA device is configured to operate in a first mode, during which the device selects an initial startup operating channel frequency, and subsequent to selecting the initial startup operating channel frequency, enters a channel maintenance mode in which a plurality of communications are exchanged between the first DSA device and the second DSA device, at least one of the plurality of communications comprising an indication of the radio frequency environment in the region of a device sending the communication, and subsequent to selecting the initial startup operating channel frequency, the first DSA device enters a channel switching mode in which a new operating channel frequency is selected for use based at least in part upon the indication of the radio frequency environment; and wherein the first DSA device enters the channel switching mode in response to a detection of a non-cooperative radio operating on the initial startup operating channel frequency. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 27, 28, 29)
