Radio access is a pretty broad high level concept. It's one of those black boxes you draw somewhere near the bottom of a phone architecture diagram, so in that sense it is low-level but that comes with the territory. BandSelection in my mind implies frequency band selection, which is a narrow aspect of radio access. The 2G/3G selection covered with this patch is about radio access _technology_, which is distinct from the actual frequency bands used by those technologies. I think RadioAccess is a fairly good name for an interface that has the potential to cover various radio related settings.

Use case for 2G/3G selection:
