Ms Katherine Licken:

I might just add to that. We mentioned working on barriers to deployment. One of the work streams the Department has is working with the NRA on access to infrastructure along the motorway - the ability to erect masts and antennae along or adjacent to motorways. The motorways were built through areas that were previously not built-up areas and would not have had high mobile usage. That is one of the areas where we believe there is a particular problem and we are working to address it. Some of the operators are saying - this is where it might be helpful to have them in - that if a person is on a 4G call and moves from a 4G cell to a 2G cell, quite often that call will drop. It is back to handsets and also the band in which the person is making the call.

Operators are saying sometimes there are temporary outages as they start to upgrade areas from 2G or 3G to 4G. It is correct to say that something has happened all right. We are aware of some - possibly not all - of it. It is an issue that would be good to take up with industry also.
