Use case · 5G WAN

One managed network in every vehicle.

Service trucks, buses, mobile clinics and command vehicles need tablets, cameras and onboard systems online on the road. A rugged 5G router and roof antenna connect everything onboard as one network.

Sound familiar?

What it looks like day to day.

A typical scenario based on the environments we work in, not a specific customer.

  • Each device tethers to a phone or has its own plan
  • Connections drop in fringe coverage
  • No visibility into what's working across the fleet
  • Onboard cameras or systems can't upload reliably

Why it happens

Vehicles move between towers, carriers and dead zones.

A rugged in-vehicle router with an outside roof antenna holds a connection far better than a phone inside a metal cab, can use more than one carrier, and is managed centrally like any other site.

What we do

How we fix it.

5G WAN connects a location to the internet over the cellular network, as its main connection, its backup, or a separate path for emergency access.

  1. Understand routes and devices

    Where vehicles go and what's onboard.

  2. Pick hardware and carriers

    Rugged router, roof antenna and the right carriers for the routes.

  3. Standardize the install

    One build for each vehicle type.

  4. Manage the fleet

    Central monitoring, updates and support.

Every site starts with a coverage check for each carrier, so the right carrier and antenna are picked before anything ships.

What changes

What's different after.

Everything online

Tablets, cameras and systems connected on the move.

Better coverage

Roof antennas and more than one carrier.

Fleet visibility

Know what's working, vehicle by vehicle.

Is it a fit?

Where this works, and where something else fits better.

We recommend what solves the problem, even when it's a different solution.

A good fit for

  • Service and utility fleets
  • Transit and shuttles
  • Mobile clinics and public safety vehicles

Something else may fit better

  • A single phone per driver with no onboard systems may not need a vehicle router

Technical detail

The design decisions, the end-to-end path and how the result is tested.

Show

The gateway must survive physical conditions while policy manages changing carrier paths and application priorities.

Design decisions

Design decisionWhat we need to understandHow we engineer it
RF systemMap routes, carriers, bands, roof location, antenna isolation, and cable loss.Use purpose-built external antennas and measured carrier combinations.
Vehicle integrationDefine voltage, ignition, shutdown, battery protection, temperature, vibration, and mounting.Install the gateway as vehicle equipment, not desktop hardware.
Traffic policyClassify dispatch, voice, video, telemetry, users, updates, and guest access.Prioritize operational traffic and control high-volume uploads.

The end-to-end path

  1. MOBILE NETWORKSCarrier A · carrier BChanging towers and bands
  2. VEHICLE RADIORoof antennas · modemsRugged mobile access
  3. ONBOARD EDGESD-WAN · VPN · Wi-FiPolicy and local network
  4. FIELD SYSTEMSDispatch · video · usersThe mobile workflow

Multi-carrier hardware is not enough. Policy must define when to switch, bond, steer, limit, or recover each application session.

How the result is tested

  • Route test Drive representative urban, highway, rural, depot, and garage routes.
  • Carrier test Measure path changes, weak zones, recovery, and multi-carrier policy.
  • Power test Exercise ignition, crank, sleep, battery protection, and restart behavior.
  • Application test Run dispatch, voice, video, telemetry, and user traffic together.
  • Environmental test Verify temperature, vibration, mounting, cable, and antenna integrity.
  • Operations test Confirm remote visibility, alerts, data usage, and support evidence.
