Default Wrc-23

A link to an Ofcom document about the World Radiocommunication Conference 2023.

Interesting part is the use of the UHF DTT frequencies between 470-694Mhz.

Ofcom and some other countries regulators is for the status quo but it appears others want more mobile use of part the band.

Seems licences for DTT are being issued at least to 2034, if I read it correctly. Have to wait to find out what the conference decides.

Ofcom are asking for input, it’s beyond me but others may have suggestions.

Digital television was introduced primarily to free up UHF spectrum which could be sold off to the mobile industry.

That's all happened, and here is the mobile industry doing the preamble for eating into the remaining (digital) TV allocation.

The long term demand is insatiable.

Only lower frequencies where antennae become too large for mobile use is safe due to their nature. Some special services like aviation, navigation (GPS and friends), and military are likely to be protected.

It's being assumed that broadcast entertainment, news, etc will be subsumed into internet over mobile services.

So, enjoy our broadcast bands while they last. They'll last for some time, but the direction of travel of RF usage is now pretty obvious. There's nothing much we can do about it other than watch. Is your pantry well-provisioned?

While this makes the future seem glum, we can exist pretty much as we are because most people wanting to demonstrate period receivers now have to source their own demonstration signals if they want anything decent to listen to or view.

Relevant to this forum, the COM7 DTT multiplex which carries BBC News HD and several other channels, is closing next week to make room for the mobile people who swallowed up COM8 last year. The future of Freeview looks decidedly bleak.
