I have a couple of these in hand. What they don't tell you there is you need to sign an NDA to get the most modern DECT versions of the software, because "it is still in development". I'm waiting for that signature now.

Also you have to dig through the data sheet to find out that the GNSS only works with LTE. If you want to use DECT GNSS can't be used, because it is part of LTE. Can't do both DECT and LTE at the same time.
