Originally GSM had a hard distance limit of 35km, which some providers
pushed to 70km with some tweaking. That was due to the TDMA nature of
GSM:

HSPA OTOH is a very different animal, I don't think it has a distance
limit due to protocol, but I'm not sure.

In any case, I measure about 15km to the tower, so I'm well within the
old GSM limit.
