SIMs for traffic management.
Temporary signals, variable message signs and counters report their status and take updates from wherever the job is today. ThingSIM keeps them connected as they move.
What the kit needs
Coverage wherever the job is
Roadworks are often in poor signal. Each SIM uses whichever UK network is strongest on that stretch of road.
Switched on per job
Keep SIMs in the kit between jobs. Activate one when a unit is first deployed, and pause it from the portal when it is parked up.
Remote control, privately
Change a message or check a fault from the office over a Private APN or IPSec VPN, without exposing the unit to the internet.
How it connects
Recommended setup
250 MB, UK 4-network, one SIM per unit.
Status reporting uses little data; units that stream images need a larger plan.
