Smart move calling what is effectively an entirely new standard "DECT" to get free use of DECT's old frequency bands that are barely used by their original use for cordless phones anymore...

DECT is still used a lot in factorys even today. It's way faster to type a short number, usually between 100 .. 999. The often used contacts you know anyway and you don't have to search in contacts. If the phone drops, nobody does care. DECT phones on work are great.

Ask HN: Why no mobile phone can also be used as a DECT phone? https://news.ycombinator.com/item?id=20909535

The bands themselves are unlicensed; anyone can use them. You don't have to be specifically called "DECT" to use them.

You do in some countries...

What countries require licensing for ISM bands?

DECT uses 1880–1900 MHz in Europe, other countries use similar frequencies, that's not an ISM band.

Fair enough, but that doesn't change the question significantly - what countries require licensing on DECT bands?

Most countries do require the equipent to be licesed, even the folks who operate and deploy then don't need to be.

And equipment for 1890MHz is not approved if it is not DECT.
