Solutions · Highways and tunnels
In a tunnel, the signal drops. Our job is to make sure it doesn’t.
We design, install, and maintain the radio coverage and monitoring systems for Autostrade per l’Italia, SITMB, SAV, RAV, Asti-Cuneo, and many other concessionaires. Over more than twenty years we have equipped more than 500 km of routes and over 100 tunnels.
The three challenges highway operators face.
What a concessionaire must guarantee every day, on the open road and in the tunnel.
Service continuity
The operational radio networks, along with those of the Polizia Stradale and the 118 emergency service, must stay live in every tunnel bore. A short circuit caused by a fire, or an open line from a faulty connector, leaves the tunnel without communications exactly when they are needed.
Safety for road users
Anyone driving through the tunnel must be able to call 112 and receive emergency instructions without installing any app. That takes cellular coverage verified around the clock and alert messages broadcast straight to the car radio.
Longevity of the investment
The system has to last for years and be maintained without closing the route. What counts is component quality, technical documentation, and scheduled work carried out overnight.
What happens when there’s an accident in the tunnel.
A real case: a rear-end collision in a tunnel bore, from the emergency call to the return to normal.
The emergency call goes through
A driver involved in the collision calls 112 from their phone. The call connects because the DAS carries the mobile operators’ signal into every tunnel, and TP-CELLX checks that it is available around the clock, day and night.
The control room coordinates the response
The operator manages the incident from the Respondr console: calling the road-maintenance crew on the route’s radio network and talking to the Polizia Stradale and the 118 service, whose radio networks reach the tunnel over the same radiating cable.
Drivers in the tunnel are warned
TP-DAB interrupts FM and DAB+ programming and broadcasts the emergency message straight to the car radios of passing vehicles, all along the tunnel: slow down, stay in your lane, do not turn around.
The incident stays documented
Once the emergency is over, the operator can reconstruct how the incident was handled: the radio communications are retained by Respondr’s built-in recording system, with the date, time, and channel of every call.
The systems we put in the field.
Each solution has its own in-depth page: here you will find only what it does for a highway route.
- Control room
Control rooms and dispatch
We build concessionaires’ radio centers with Funktronic consoles and the Respondr platform: managing the route’s radio networks, GPS location of crews, and man-down alerts from a single operator position.
- Operational radio
DMR and TETRA radio networks
We design and build the route’s operational radio networks: DMR Tier II systems in simulcast (same-frequency) configuration, TETRA trunking, and VHF/UHF links, from design to maintenance.
- In-tunnel coverage
DAS and radiating cable
We design and install multiband DAS and radiating cable systems, carrying TETRA, DMR, VHF/UHF, and cellular on the same line: it is the solution we have used to equip over 100 tunnels.
- Radiating cable continuity
TP-CCV2
A patented Teleproject system that flags short circuits and open lines on the radiating cable in real time, before the tunnel loses radio coverage.
- Cellular coverage
TP-CELLX
Continuously checks cellular coverage in the tunnel and alerts the control room when 112 and 118 can no longer be reached.
- Spectrum monitoring
TP-RFX
An outdoor spectrum analyzer that watches the TETRA, DMR, FM, and DAB carriers in the tunnel: it detects radio signal degradation before it becomes a service outage.
- Alerts on car radios
TP-DAB
It rebroadcasts FM and DAB+ signals in the tunnel and, in an emergency, interrupts the programming to send the alert message straight to car radios, all along the tunnel.
- Traceability
Communications recording
Audio recording systems for operational and emergency radio communications: every call stays documented and available to reconstruct events.
- Sensors and monitoring
LoRaWAN solutions
LoRaWAN networks and sensors for monitoring environmental and infrastructure parameters along the route, with the data collected on the Track-TP platform.
- Site-to-site links
Microwave radio links
Point-to-point and point-to-multipoint microwave links to connect the route’s radio sites and control rooms where fiber does not reach.
- Radio terminals
Radio fleet supply
Supply, programming, and maintenance of the crews’ radio terminals: we are authorized resellers for Motorola Solutions, Hytera, and Kenwood, and the exclusive Funktronic distributor for Italy.
- Before the tender
Radio coverage study
Propagation models, link budgets, and system sizing: the technical documentation you need to design the coverage and present the project in a public tender.
Our systems integrate with the equipment you already have.
No closed systems: we use open protocols, let different technologies coexist on the same infrastructure, and hold the certifications that public tenders require.
Multi-protocol on the same cable
TETRA, DMR, and VHF/UHF coexist on the same radiating cable: existing investments stay valid even when the radio technology changes.
Integration with the tunnel SCADA
The monitoring systems interface with the tunnel SCADA and with the operator’s platforms through SNMP, relay contacts, and APIs.
Certifications and qualifications
Teleproject is an ISO 9001:2015 certified and SOA OS 19 qualified company. The Respondr and Track-TP platforms are designed in compliance with the NIS2 directive and the ISA/IEC 62443-3-3 standard.
