IEEE 1900.5 enabled whitespace database architecture evolution

Increased demand for electromagnetic spectrum (licensed and unlicensed) has spurred the development of sharing techniques based on databases and the development of FCC rules requiring them for TV Whitespace bands. These concepts are also being considered for other sharing scenarios. Many standards groups have already begun standardizing solutions for TV Whitespace, including the IEEE, the IETF and ETSI. As these techniques are just starting to be deployed it is anticipated that there will be “lessons learned” which could prompt modifications to spectrum sharing requirements after initial deployment. The IEEE 1900.5 WG is developing a series of standards that will allow increased spectral flexibility when coupled with the sharing solutions being developed by other standards groups. This flexibility will allow new sharing requirements to be addressed as they emerge - even in deployed systems. This paper relates the policy-based control architectures in the IEEE 1900.5-2011 standard to proposed database sharing architectures, and goes on to describe the applicability of two IEEE 1900.5 standards which are currently under development-P1900.5.1 Draft Standard Policy Language for Dynamic Spectrum Access Systems and P1900.5.2 Standard Method for Modeling Spectrum Consumption - to requirements for database enabled spectrum sharing.
