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 a project developed at Fundamentals of Networking Lab in Electrical Engineering department of University of Washington.
Our team has implemented a fully functional TVWS DBA, as defined by FCC, considering all technical specifictions of primary transmitters in TV band such as TV broadcasters, Wireless microphones, Personal land mobile radio services, Commercial modile radio services, etc. We apply all FCC policies for unlicensed spectrum access in TV white space spectrum to provide the most accurate list of available channels.
The information provided by this service extends beyond what is specified by FCC for certified DBAs and what is currently provided by existing DBAs. These features make our platform more interesting to researcher as well as companies that are active in white space spectrum. The additional features include but not limited to the following:
- We provide detailed information about protection area of various primary entities in TV band
- Quality of each channel is estimated by noise floor considering all active primary transmitters in the environment
- Effect of different path loss models on calculation of protection region is provided
- Statistical information about channel availability per State or County is available on the website
- Available white space capacity over the entire United States is presneted in color map format
