(74) Attorney, Agent, or Firm—Whitham Curtis Christofferson & Cook, PC (57) ABSTRACT High quality communications among a diverse set of cogni tive radio (CR) nodes is permitted while minimizing interfer ence to primary and other secondary users by employing Dynamic Spectrum Access (DSA) in a Dynamic Cellular Cognitive System (DCCS). Diverse device types interoper ate, cooperate, and communicate with high spectrum effi ciency and do not require infrastructure to form the network. The dynamic cellular cognitive system can expand to a wider geographical distribution via linking to existing infrastruc ture.
