The Mässtunneln tunnel in Stockholm is a tunnel project in which TrollKom is supplying wireless communication infrastructure in collaboration with Veidekke.
The solution includes WiFi, RTLS, and Kinetic Mesh technology to ensure stable and robust communication in a demanding tunnel environment.
Tunnel construction places special demands on network solutions. The environment is characterized by rock, concrete, moving machinery, moisture, and dust, all of which affect radio signals and operational reliability.
Achieving reliable communication requires technology that is adapted to dynamic and changing working conditions.
Challenges in tunnel construction
In a tunnel project such as the Mässtunneln, communication is a key part of both safety and efficiency.
Some of the technical challenges in this type of environment are:
Elongated and curved tunnels
Changing topology as the project develops
Reflections and shadow areas in rock and concrete
Machines and vehicles that are constantly moving within the network
The need for stable roaming without interruptions
Requirements for real-time information about personnel and equipment
A traditional wireless solution is rarely sufficient in such environments.
A self-healing and redundant network is required that can adapt when conditions change.
WiFi and Kinetic Mesh in tunnels
Kinetic Mesh technology is used as the basis for the wireless infrastructure in the Mässtunnel.
The mesh architecture enables the network to continuously optimize connections between nodes and find alternative routes in the event of disruptions.
This provides:
Robust communication even in the event of temporary obstacles
Stable coverage in complex tunnel environments
Improved operational reliability
The ability to move and adapt the network during the project
The WiFi infrastructure serves as a foundation for several types of services, including data transfer, communication systems, and real-time positioning.
RTLS for personnel and resources
As part of the delivery, RTLS (Real-Time Location Services) is implemented to enable the positioning of personnel and equipment in the tunnel environment.
RTLS in tunnel construction contributes to:
Increased safety through improved situational awareness
More efficient coordination between work teams
Improved evacuation management
Documentation of presence in different parts of the project
By combining RTLS with a stable WiFi and mesh infrastructure, a platform for real-time data is established in an otherwise demanding and complex environment.
Communication in demanding environments
TrollKom’s solution in Mässtunneln is adapted to working environments with high demands on availability and robustness.
The combination of Kinetic Mesh, WiFi, and RTLS enables a flexible and scalable infrastructure that can grow in line with the project’s needs.
In tunnel environments, it is crucial that communication works without interruption.
A stable connection between personnel, vehicles, and management is a prerequisite for both safety and operational efficiency
Wireless infrastructure in Swedish tunnel construction
Projects such as Mässtunneln show how modern wireless technology can be integrated into Swedish tunnel construction to create better working conditions.
By using mesh-based networks and RTLS, tunnel projects can benefit from:
A digitized work environment
Improved safety monitoring
Efficient information sharing
Better decision-making in real time
Mässtunneln is an example of how robust WiFi and RTLS can be implemented in a tunnel environment in Stockholm and contribute to more connected and structured production.
