It's a much more robust method for transmitting digital information, and when combined with the switch back to UHF, it will let local TV stations offer a clearer signal with broader reach and fewer interference issues. With ATSC 3.0, broadcasters are switching back to UHF and moving to orthogonal frequency-division multiplexing (OFDM), the same technology behind the latest Wi-Fi and mobile wireless technologies. The VHF band used is prone to interference from buildings and trees, weather and even passing cars, and the digital data it sends is easily corrupted, which shows up on your TV as a blocky, unwatchable picture, or even just a "no signal" message.
