AbstractSpectrum sharing between federal and commercial users is proposed by the FCC and NTIA to open up the 3.5 GHz band for wireless broadband use. The proposed technology requires the detection and subsequent allocation of available licensed spectrum for temporary use by other users without compromising the privacy of the licensed user. DoD has a documented requirement of 865 MHz by 2025 to support telemetry but only 445 MHz is presently available. Research is presently on-going at DoD to realize, test and evaluate spectrum efficient technology with the aim to develop, demonstrate, and evaluate technology components required to enable flight and ground test telemetry operations. The use of cognitive radio (CR) in spectrum sharing has gained much popularity in that CR senses the unused spectrum at a specific time and location and dynamically allocates to users as required. This paper will provide an overview of a secured CR Media Access Protocols using the IEEE 802.22. Carrier Sense Multiple Access Collision Avoidance (CSMA/CA) will be utilized for protocol transmission in order to properly identify user’s location and identity thereby providing a secured network against false alarm from external attack.
