Next generation TVs can broadcast data alongside video
Inventions
Modern television towers are being transformed into massive wireless routers, capable of beaming software updates and emergency maps to cars without using a single byte of cellular data.
While traditional television signals only carry sound and image, a new standard called ATSC 3.0 allows broadcasters to treat their airwaves like a massive wireless pipe. This technology, known as datacasting, can squeeze 25 megabits of pure internet protocol data alongside a 4K video stream. It uses a sophisticated method of vibrating radio waves that makes the signal nearly immune to the 'ghosting' interference caused by tall buildings.
