REsurrecting a zombie
I hadn't realised that smart meters rely on their own data signal (via mobile phone masts or radio). Seems that only one company, Craptiva, run this. Complete monopoly of shite, by all reports.
My brain did a 'wtf' over this. Security is cited as the reason, but since comms such as WhatsApp, that use end-to-end encryption, are secure, really can't see a reason why a dedicated network has had to be created.
Oh, wait. Craptiva and outsourcing. There is the reason. I wonder how much the contract is worth.
