Author: Ethan Ace, Published on Jan 11, 2012

Needing line of sight for wireless connectivity has always been a major pain for surveillance application Cameras are often needed where there is no direct, clear path from camera to building or headend. To compensate, design complexity and cost often skyrockets.

TV white space radio technology, using frequency space freed by the shutdown of analog television broadcast, aims to reduce these line of sight issues. In this update, we examine the technology, products available and potential impact.
