We summarize a new language for expressing policies that allow opportunistic spectrum access. A Policy Reasoner that reasons about these policies can be used with cognitive radios to guarantee policy-specified behaviors while allowing spectrum sharing. We evaluated the reasoner in a demonstration. We describe the policies used in that demonstration and the results of the evaluation.
