TETRA isn't interoperable?

Its introduction has been an unmitigated disaster in Germany (as apparently and unfortunately is wont in Germany), see https://de.wikipedia.org/wiki/BOS-Funk#Einf%C3%BChrung_in_De... (German-only, sorry).

It's still not universally implemented and hospitals aren't part of the network either.

That's funny. UK is now switching off TETRA to a new ESN network; based on LTE. Quite a few issues with it, so it will be a while yet, but most of the masts are built. It will also allow coverage in rural areas to improve (as operators can share the masts built for the emergency network).
