Most of the streetlights in Surrey use a radio control system using something called a Leafnut.
There are central nodes which communicate via GSM to the council and 868MHz to leafs (streetlights connected to the node). They take a SIM card but does anyone know which operator?
And yes, they have problems where the nodes can't pick up a mobile signal! This is despite many being mounted at 9M+ (so higher than your average mobile user!)
