On the radio they are discussing this pressing matter: why we are so far behind the rest of the world in 4G rollouts.

Surely they must know that British radio waves can only carry a fraction of the traffic that (say) American airwaves can.

That’s why we can only have up to 5 terrestrial TV channels, and why Radio 2 had to take up a full 4MHz of bandwidth to capture the chestnut tones of Terry Wogan.

It’s quality… or the weather… or something.
