Geographic Contour Calculations

In the United States there are areas where spectrum allocated to TV broadcast is not fully utilized, and secondary use of this spectrum has been authorized by the FCC under Part-15 Rules, wherein one or more white space administrators provide available spectrum information to low-powered transmitters (also called white space devices or “WSDs”) to ensure that primary spectrum users and services do not receive interference. In the white space rules the Federal Communications Commission addresses protected services from the context of two large categories: • Those services already registered with the Commission and • Those services not registered with the Commission but otherwise entitled to some form of protection This book evaluates the FCC white space Rules and provides best practice and implementation guidelines to consistently implement geographic spectrum sharing.
