I would imagine towers from different companies is part of it.

Also, there are going to be areas on the edge of coverage where your  
phone can detect the signal, but reception would be very poor  
(frequent drop outs &c). So the distribution of cell towers will  
reflects that - enough so there's always one you get good coverage  
from, and incidentally there will always be some more distant ones  
your phone can recognise.

If I'm understanding this right, the phone may be registering with  
these more distant towers, which might beg the "why" question. But  
it's likely the cell companies have lots of towers with overlapping  
coverage, so it's surely not a problem.
