Digital Terrestrial Television
Digital terrestrial television (DTT) is a broadcasting method that transmits television signals via radio waves from ground-based towers to antennas on homes, providing clearer images and more channels than older analog systems. This technology has been pivotal in the global shift from analog to digital media, freeing up spectrum for other uses like mobile data while enabling features such as interactive programming. In today's world, it's increasingly competing with streaming services, but remains essential in areas with limited internet access.
Did you know?
The global transition to digital terrestrial television, completed in many countries by the 2010s, freed up vast swaths of radio spectrum—such as 108 MHz in the US—that were auctioned for $19.6 billion and repurposed for 4G and 5G networks, dramatically boosting mobile internet speeds worldwide. This shift not only ended the era of fuzzy analog signals but also inadvertently sparked innovations in wireless technology that now connect billions of devices.
