Band WATCH -- wireless data delivery over active TV channels

The video discusses the expected 1000% growth in mobile data over the next five years, necessitating more wireless spectrum. The UHF band is ideal for wireless data transmission due to its ability to carry signals over long distances without obstruction. However, in urban areas, much of the UHF band is occupied by TV channels. The WATCH system, developed by Edward Knightley, uses unused UHF TV channels for Wi-Fi by employing signal canceling techniques to avoid interference with TV reception. This technology is expected to become crucial as demand for wireless data increases and TV viewership declines.
