Xcor is the core technology used by Hunter in both the Headend and Field equipment. The building block of the entire Hunter platform, this patent-pending technology uses existing digital channels as its radar probing signals, therefore utilizing zero bandwidth for the radar process. Without the Xcor technology, the concept of locating impairments using radar technology would be completely impractical, due to excessive bandwidth requirements. Since the initial introduction of Xcor, several product iterations have taken place and the result is a rock-solid technology that has proven its reliability and effectiveness in installations throughout the world.
