Welcome to Spectrum Observatory! This is a collection of web-based tools for analysis, simulation and modeling of Dynamic Spectrum Availability, with a focus on TV white space spectrum. How to use : Input an address of the location you want to see available white space capacity only in the U.S regions. ex) 1410 Northeast Campus Parkway, Seattle, WA 98195
Select one of the modes. In the point mode, drag & drop a marker into the location you want to see white space data and choose a device type to see the minimum separation distance for secondary device around the marker. Also, the average white space data can be queried for selected counties or states on the map. This function is available only for the U.S regions.
The protection regions of each TV channel are displayed on the map. Please choose one of the TV channels you want to see. You can also clear the displayed protection regions on the map by clicking the "Clear All" button.
The Color map shows colorfully available capacity for regions in the U.S. Please choose all or a state in the U.S. You can also clear the displayed color map on the map by clicking the "Clear All" button.
Spectrum observatory is developed at Fundamentals of Networking Lab in Electrical Engineering department of University of Washington. For more information about our research lab and other activities by our group please visit http://www.ee.washington.edu/research/funlab/.
