OFSO- you are indeed right about terrain suiting the medium used- hilly and dry is great so long as they are the right kind of hills and don't cast 'shadows' over large population areas.
For most places tho ' and urban areas fibre optic remains king
On the Telefonica point you are so right, they are the very worst company to deal with in any respect and I hope they leave your local service provider in place for many years to come
