A great deal of complex, behind-the-scenes work goes into delivering the hundreds of channels enjoyed by millions of people across the UK each and every day. On the UK DTT network, a channel goes on an epic journey before it reaches people’s screens, and we are involved at every step of the way.

We are responsible for managing and maintaining the 1,154 transmitter sites dotted across the UK; the infrastructure that delivers the broadcasts signals straight to your Freeview-enabled television or set-top box (STB). This service ensures UK DTT multiplex operators, as well as our own commercial multiplexes, stay on the air and keep UK television audiences glued to their seats.

We’re proud to play such a critical role in the world of TV in the UK. Always.

Infrastructure and Services

We've seen it all. From black and white televisions to the introduction of the world's first Digital Terrestrial Television network. We know TV.


TV network design

The planning of a TV network starts with the available electromagnetic spectrum and designing a network which optimises that scarce resource.


Coding and multiplexing

A multiplex, in simple terms, is an ensemble of television channels which are grouped together in order to fit efficiently into the channel bandwidth determined by the frequency plan.


Distribution and transmission

The output of the multiplex is fed to the distribution network. The distribution network links the multiplexing centre(s) to the transmitter sites ready for transmission across the UK.

Case Study

700MHz Clearance - Arqiva Case Study

In November 2014, Ofcom announced that the 700MHz band, currently occupied by a number of digital terrestrial television (DTT) services, is to be cleared for use for mobile data by 2020.
