Daily Wireless reports that Microsoft will release a paper (PDF) next week about its SpecNet analyzer for shared White Space use.
As outlined in the abstract the problem: “there exists no infrastructure today for measuring real-time spectrum occupancy across vast geographical regions.”
The SpecNet solution: “We demonstrate the value of SpecNet through three applications: 1) remote spectrum measurement, 2) primary transmitter coverage estimation and 3) Spectrum-Cop that quickly identifies and localizes transmitters in a frequency range and geographic region of interest.”
Daily Wirelss translates: “The SpecNet architecture, developed at Microsoft Research, contains three key components: users or clients, slave servers that comprise laptops/PCs connected to spectrum analyzers, and master servers that manage the slave servers.”

One of the big challenges with White Space shared usage is that there is a need for a lot of spectrum analyzers in many locations. Spectrum analyzers are expensive to date but the SpecNet system would allow for easy data sharing via XML and a standard set of APIs.
The White Space represents a unique opportunity for ground up innovation of unlicensed spectrum.
