Course it must a country of that size I'm sure they don't bother to
cover all of it do they?.

No they don't, but because of the digital cliff seen
with GSM you either have coverage or you don't.

Wrong.

Nope.

The data is still tranmitted using RF.

You quite sure you aint one of those rocket scientist fellas ?

The fact that the underlying data is encoded digitally is irrelevant.

Wrong, as always.

The GSM digital cliff happens because with the GSM system, even
when the base can hear the handset fine, if its too far away as
determined by the round trip delay, it ignores it completely.

Thats not quite a same thing as was implied there are areas within the
otherwise usable service area of a base station that are difficult owing
to topography..

Do you have any hilly areas like say the Welsh valley's?..
