The Microsoft Spectrum Observatory (http://observatory.microsoftspectrum.com) was created with the purpose of providing an intuitive presentation of the usage of the wireless spectrum. The project is sponsored by Microsoft's Technology
Policy Group and the data is made freely available to the public. Data is recorded through monitoring stations and is stored and processed for visualization through the Windows Azure cloud. Eventually, the goal is to have spectrum monitoring stations set up
all over the world. Microsoft believes that the data gathered on spectrum utilization will help inform policy discussions and decisions implicating various forms of spectrum management – ranging from reallocation of spectrum for exclusive use licensing or
unlicensed access to dynamic access to allocated but unassigned spectrum. To support this effort by collecting spectrum usage data, measurement units have been installed by Microsoft and partners in various locations around the world. Microsoft philosophy
in developing this program has been to keep costs low and to keep the solution flexible and open to others.
