OT deep packet inspection lets a router read Modbus, DNP3 and S7 commands, not just ports. Few cellular routers do it natively: Moxa’s OnCell G4308 does, rugged 5G firewalls do on subscription, Teltonika doesn’t, and IoT SIM networks can’t see inside your OT traffic.
Attackers hijacked Danfoss refrigeration controllers in hundreds of French supermarkets and forced them into defrost. What happened, what it cost, who is responsible and what UK operators should check this week.
The history of IoT started long before the internet. Shop door beams, the Teasmade, X10, the TV clicker, The Clapper, light guns and a Cambridge coffee pot all solved the same need, and ran into problems we still fight today.
Underground coverage never happens by accident: someone builds it and someone pays for it. Boldyn’s neutral-host Tube network shows the model, and the same questions about voice, VoLTE, repeaters and single-operator SIMs apply to every car park, basement, tunnel and mine.
