The Federal Communications Commission (FCC) is proposing a new rule regarding how to determine the availability of channels for unlicensed devices in the TV bands, which are known as white spaces. The FCC seeks feedback on using a model called Longley-Rice, which takes into account the terrain to predict signal availability more accurately compared to the current method. The aim is to see if this model can better serve both white space device users and television broadcasters while still protecting broadcast signals from interference. The FCC invites public comments on various technical and implementation aspects of using this model.
Simple Explanation
The FCC wants to figure out a new way to check if certain radio waves, called "white spaces," are free for use by gadgets without causing trouble for TV signals. They’re asking people for ideas on using a special model that looks at hills and valleys to find these spots better.
