On improving serviceability with quantified dynamic spectrum access

Dynamic spectrum access is being investigated to meet the ever-increasing demand for wireless spectrum. We introduce a quantified dynamic spectrum access (QDSA) model for efficient sharing of spectrum among multiple heterogeneous networks. The QDSA paradigm enables us to define and enforce quantified spectrum-access footprints for the cochannel transceivers. By controlling the spectrum consumption by each of the individual transmitters and receivers, efficient spectrum sharing can be accomplished. In order to improve serviceability, we investigate the impact of the design choices for a spectrum access mechanism (SAM). The experiments demonstrate the significance of the active role by the incumbents, the impact of the granularity of spectrum access, and the need for transceiver standards for accomplishing efficient usage of the spectrum.
