Cognitive Pilot Channels for femto-cell deployment

The Cognitive Pilot Channel (CPC) is a mechanism for disseminating information about available radio access technologies to future reconfigurable devices. This paper proposes and investigates the idea that CPC technology for heterogeneous cognitive radio networks may present an attractive solution to some of the challenges facing femto-cell deployment. The benefits of using the CPC in this way are described and a comparative analysis of this approach against fixed-line oriented solutions is presented. As a result of this comparison the viability of the CPC approach in both the short-and long-term is discussed.
