The old rules requiring 2-3 days of battery power backed up by diesel
generators should be applied to the mobile phone networks. It is
understandable that the mobiles were exempted when they were new, and we
could fall back to POTS in an emergency, but now that POTS landlines are
disappearing that will not work anymore. But I am fairly sure that the
industry will see to it that that cannot happen.
