In this paper, we present the simple idea of using the proposed device in Cognitive Radio to reuse locally unused spectrum for their own transmissions. We impose the constraint that they cannot generate unacceptable levels of interference to licensed systems on the same frequency. Using received SINR as a proxy for distance, we prove that CR vary its transmit power while maintaining a guarantee of service to primary users. We consider the aggregate interference caused by single CR user and multiple CR users using the proposed device.
