A Case for Coordinated Dynamic Spectrum Access in Cellular Networks
Overview Majority of research in Dynamic Spectrum Access (DSA) networks has focused on free-for-all, opportunistic spectrum access for peer-to-peer ad-hoc communication, typically targeting military applications. This paper proposes that a simple form of DSA called Coordinated DSA that relies on a regional spectrum broker to control spectrum access can bring benefits to current statically provisioned cellular networks. The authors argue that two concepts, namely a dynamically sharable spectrum band called Coordinated Access Band (CAB) band and Statistically Multiplexed Access (SMA) to spectrum that relies on demand aggregation can achieve better spectrum utilization. The paper describes in detail the spectrum measurements in existing cellular networks to conclusively demonstrate the feasibility of these concepts.
