[srslte-users] TDD / NB-IoT / 5G?

Hi,

Interesting. So choosing a TDD ARFCN is enough to activate it? B40 is interesting, as it is a ham band.

OK, like I had expected.

The carriers can be seen nicely in the spectrum, in Germany we have Vodafone and Telekom transmitting in the 800 and 900 MHz bands.

So at least smth. to play with :) TNX!!
