Just pay the bloody money
In the grand scheme of things five hundred quid extra per handset isn't obscene, if it works.
Remember the Lancaster power cut : http://www.lancaster.ac.uk/media/lancaster-university/content-assets/documents/engineering/RAEngLivingwithoutelectricity.pdf
'Mobile phone systems did not hold up. On most networks, the base station (the transmitter that provides the radio signal to communicate with phones in that area) is powered from the local 230V electricity supply. Some have a battery back-up that continues to provide a service for an hour or two but few, if any, cope with the 30-hour loss or supply experienced over much of Lancaster'
Airwave key sites have a seven day power supply and a deployable mobile base station according to their website.
4G is still a joke, I wouldn't rely on it for anything. Too many areas where it's slow or unavailable, even in major cities. Not to mention places in the countryside where there is no mobile signal, at all.
