Correct, at least so far as the BTS equipment used by Orange is concerned.

As does Orange. As, I should imagine, do all the incumbent networks.

Certainly not the case with Orange (and neither would I be certain of that
being the case with Voda either) - each of the 3 combinations are perfectly
possible and examples of such can be found amongst the 15-odd thousand sites

Orange "streetworks" (in common with every other type of installtion) are
perfectly capable of being 2G, 3G or dual.

I won't bother adding much to harrogate's reply here, because it says much
of what I was thinking. All I would say is, the microcell (which is the
correct term for these lamppost sites - "streetworks" is merely one type of
microcell site, along with "wall mounted", for example) equipment -
depending on its location - could be serving anything from particular floors
of a building (very low-powered ceiling mounted antennae), to a particular
block of buildings (using directional antennae), to a street or housing
estate (using a low-powered omni-directional antennae).
