What does dual channel actually mean?

It means that you could run a BTS with two completely independent ARFCNs.

Can you use 2 different frequencies at the same time like 900 and 1800 or is it same band but different arfcn?

Theoretically you should be able use different bands with the only limitation that in this case you can't benefit from receive diversity.

Note, that dual-TRX support is implemented in UHD, but is not yet implemented in OpenBTS. The code is almost there, but need some more work.
