Re: As always...
Sharon White/Ofcom "Where is the all this (dark) fibre to support all this new mobile spectrum?"
Oh dear... how is Sharon White (or anyone else) to know where the fibre needs to run to, and in what quantity until the MNOs draw up their plans and place orders?
And if she (or anyone else) said to fibre installers "JFDI" their response would - quite reasonably - be "who is going to pay for this?"
It is, or will be, the MNOs problem to decide what network connections they require, and then to order and pay for them, either up front or via a negotiated long term lease.
Or are you expecting the taxpayer to fund a semi - speculative network in the hope that the MNOs will eventually pay enough to cover the costs?
And rural locations are generally short of street lights anyway.
