Solutions — Smart Traffic
A bus is a moving asset. A tunnel has no duct. A roadside camera cabinet sits in the sun and the rain for ten years. Traffic projects fail on connectivity long before they fail on application software — so we build the part that carries the data: cellular routers with GNSS, long-range bridges that replace a trench, and switches that hold up inside a cabinet.
Vehicles need cellular plus position reporting, and they need to stay connected while crossing between cells and between coverage areas.
Tunnels, viaducts, cross-sea crossings and live carriageways make fibre impractical. Wireless backhaul is often the only option, and it has to survive multi-hop.
Roadside enclosures see direct sun, condensation, dust and a wide supply range. Wide-temperature, DIN-rail hardware with a proper DC input range is not optional.
With hundreds of stops or cabinets, a truck roll costs more than the device. Remote configuration, monitoring and reboot are what keep operating cost down.
Most traffic projects use the same three layers. We supply the middle one and hand the data to whatever platform you already run.
4G or 5G depending on the variant, GNSS for vehicle position reporting, serial ports for legacy sign controllers, and remote management so a firmware change does not mean a site visit. This is the part that goes inside the bus or the stop.
For tunnel portals, cuttings and cross-water links where trenching is not viable. Deployed as a pair. Lets you place a camera or an AP where there is power but no network.
When one cabinet holds several cameras, a controller and a router, a managed switch keeps the broadcast domains sane and lets you see which port went down.
Station and platform coverage where passenger Wi-Fi or staff handhelds need to roam between APs without dropping session.
A municipal transit operator runs LED and e-paper arrival boards at stops across the city. Each board needs a backhaul for the passenger-information feed, and the fleet position data has to reach the depot system continuously.
Used: a 4G industrial router with GNSS per stop and per vehicle — network connection plus position upload, with peripheral expansion for the sign controller.
On a metro line, coverage has to run the length of the tunnel and hand over between radios as trains pass. On a subsea crossing, engineers needed to reach terminal equipment from a surface vessel and read live charts without running cable.
Used: wireless bridges and APs in multi-hop for the tunnel bore; a 5G router at both ends of the crossing for remote data access.
Traffic authorities place video and plate-recognition cameras at key sections. The link has to carry video without dropping frames, and the cabinet has to be installed and forgotten.
Used: 4G industrial routers providing the link layer, chosen for stable throughput, low latency and simple setup.
Announcements have to reach every platform, including during incidents when passenger guidance matters most. Latency and switchover behaviour are the whole requirement.
Used: ring-network switches for the PA backbone, giving fast response and a path that survives a single link failure.
Traffic projects differ mostly in site count and in what sits in the cabinet. These seven answers are usually enough for a first price and a delivery date.
