The Microsoft Technology Policy Group is currently collecting frequency usage data from a number of sensor base stations. Select a sensor location to view more detailed reports and graphs about the spectrum usage.

The Microsoft Spectrum Observatory 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.
