As part of the Implementation, the mast is probably going to get a fibre connection from our local Exchange
A cellular mast won't use consumer internet connections that go through the exchange, but will use a corporate "leased line" type connection from the mast directly to the network operator(s) whom are on the mast. Not directly to the internet.
Whilst they will use fibre optic cabling, it won't be consumer broadband "fibre".
