Reliable communication for transport and tunnel infrastructure

Norphonic provides rugged VoIP communication solutions for road tunnels, highways, bridges and other transport environments where reliable emergency communication is critical.

Industry context

Communication where safety matters

Reliable emergency communication is an essential part of modern transport infrastructure. In tunnels, on highways and across bridges, communication systems must remain available when conventional mobile reception may be limited or unavailable.

Kay challenges

Limited Connectivity

Underground tunnels and remote road sections can have limited or no mobile coverage, making dedicated emergency communication essential.

Harsh environments

Roadside and tunnel equipment is exposed to dust, water, temperature changes, vibration and potential vandalism.

Reliable Emergency Communication

Emergency telephones must remain operational and immediately available when an incident occurs, while distributed systems need to be monitored and maintained efficiently.

how it works

Emergency communication across the network

Emergency roadside telephones can be distributed throughout tunnels and along road infrastructure and connected to a central control facility over an IP network.
