The short answer
I would fit a vehicle-rated router with ignition sensing and GPS, a roof-mounted combination antenna for cellular, GPS and Wi-Fi, and dual SIMs on different networks so the vehicle keeps a connection as it moves between masts.
The problem
A moving vehicle hands over between masts constantly, passes through coverage gaps and runs off a battery that must not be flattened overnight.
Roof steel blocks signal, so a router with antennas inside the cab performs badly.
Here is what I would do
- Use a vehicle-rated router Look for wide voltage input, ignition sense and a delayed shutdown so it does not drain the battery.
- Fit one roof antenna for everything A combination antenna with 4×4 MIMO cellular, GPS and Wi-Fi keeps the roof tidy and the cabling simple.
- Two networks, not one Dual SIM on different networks fills coverage gaps along a route.
- Use GPS properly Feed location into tracking or telematics so the router earns its keep beyond internet access.
- Manage it remotely Vehicles are hard to get back to the depot. Update and diagnose them over the air.
The kit I would use
- RouterVehicle 4G or 5G router
Ignition sense, GPS, wide voltage input and vibration-tolerant connectors.
- AntennaRoof-mount combination antenna
Cellular MIMO plus GPS and Wi-Fi in one housing.
- SIMTwo business SIMs on different networks
Or a multi-network IoT SIM.

Questions people ask
Will the router flatten the vehicle battery?
Not if it supports ignition sensing and is wired to shut down after the engine stops.
Can passengers use the Wi-Fi?
Yes. Put them on a separate network from any vehicle systems, with sensible limits.
Do I need 5G in a vehicle?
Not always. 4G covers most fleet telemetry. 5G helps for live video, heavy passenger Wi-Fi, or where 5G has better coverage on the route.
