Do you watch BT Sport? Maybe you are a football fan who can’t get enough of the UEFA Champions League, perhaps you like the boxing on BoxNation or are more of a rugby union aficionado. You might not be aware of it, but the BT Tower has a significant role in bringing sporting action to your TV – every Premier League stadium sends content via fibre link to the Tower, which sends it to broadcasters.
In our ‘Secrets of the BT Tower’ series, we’re exploring some of the hidden elements of one of Britain’s most famous buildings. In the video below, find out about the Tower’s role in taking BT Sport “from grass to glass”.
The BT Tower was opened in 1965 by Prime Minister Harold Wilson. Its primary role was to communicate with the UK’s radio network, carrying telecommunications traffic from London, via aerials to the rest of the country.
Built from 13,000 tonnes of concrete, steel and glass, the Tower is designed to sway 20cm from vertical (for example in high winds), so radio transmissions aren’t affected. During the summer it expands, while in the winter it contracts and can be 23cm smaller.
So, next time you are cheering for your favourite football team, remember the role the BT Tower plays in bringing the match to your screens.
