Getting frequency band in use

[Markus Gothe]

Is it Telenor or / and other companies? TDD/FDD?

When Telia went on 850MHz here in Sweden some years ago they a pretty awesome got a boost in coverage.
We’ve also had 800MHz TDD for years now and compared to 2600MHz FDD it is to be considered slow, but not bad.
