About COMLAB

The Swiss company COMLAB has been a specialist in high-frequency technology in the railways sector for 40 years, and develops, manufactures, sells and installs ready-to-use communication systems for tunnel and in-train use.

Due to its longstanding experience as a single point of contact, COMLAB is able to guarantee unique standards of quality and know-how in every process stage.

Innovative, reliable and durable, our systems represent a cost-effective, long-term investment for our customers. At the same time, our highly qualified engineers attribute the utmost importance to individual consultations, customer-specific solutions and support.

Our key customers include international rail and train building companies, as well as mobile operators and emergency services organisations.
With branches in Germany and China and its global co-operation with a wide range of partners, COMLAB is able to respond effectively to the requirements of its customers all over the world.

Wireless coverage solutions for railways

COMLAB provides a comprehensive range of wireless coverage solutions. COMLAB’s repeater systems are suitable for various applications such as railway and metro line tunnels, road tunnels, buildings and in-train coverage. Thanks to many international contracts, we are one of the market leaders in the railways sector.

The system ensures that radio signals can be received inside their areas of use. Radio signals are not able to penetrate rock strata and certain strongly insulated areas, for instance. Therefore, the external antennas pick up the provider signals and the system amplifies and distributes them via leaky feeder cables or internal antennas.

Modular radio systems for the rail industry

COMLAB’s systems consist of modular components that can be easily integrated and perfectly adapted to the client’s requirements. This modularity also facilitates subsequent expansion and retrofitting.

Mobile radio services and digital audio broadcasting

COMLAB supplies mobile radio services, intercom facilities for the police, DAB, VHF and GSM-R technologies, analogue and digital radio for the emergency services, as well as in-tunnel GSM services for passenger mobile communications. Various technologies can be combined in a single system.

Engineering consultations for rail radio solutions

COMLAB overlooks every stage of the development, production and implementation processes of its radio systems. Qualified and experienced graduate engineers guarantee innovative engineering, and are available to advise clients, design systems and develop new components.

COMLAB’s specialists provide clients with comprehensive solutions that are specifically designed for their needs.

InTrain Repeater Solution

The COMLAB InTrain repeater solution perfectly compensates for the high signal loss caused by modern train vehicles, which are very well-insulated with special thermally-insulated glass. It was specifically designed for extremely challenging use on high-speed trains.

Remote Unit Digital: RUD-5

The RUD-5 has been designed in order to extend radio coverage in various radio networks. Available as a fibre-optic repeater or an off-air repeater, it is suited to numerous areas of use.

Railway and Metro Tunnel Repeater Solution

The COMLAB repeater system is a multi-operator and multi-band radio coverage system which is able to combine radio distress and safety systems (TETRA, TETRAPOL), global systems for mobile communications on railways (GSM-R) and public mobile telecommunications systems (GSM, UMTS, LTE) with one another, and to simultaneously protect them against mutual sources of interference.

Metro and Railway Systems

For over thirty years, we at COMLAB have focused on radio frequency (RF) technology. Our involvement includes design, development, production and installation of turnkey high-frequency radio systems.
