DAS & Repeater Solutions

Discover our end-to-end coverage systems for train and street tunnels, in-train communication, and in-house projects.

Pioneering Radio Frequency Technology Since 1971

Our experts at Kontron Transportation Schweiz AG (formerly COMLAB) have led the radio frequency technology field for over 50 years. Combining Swiss engineering excellence with decades of hands-on experience, we design and deliver highly reliable, tailor-made DAS and repeater solutions precisely aligned with customer requirements.

Perfect Coverage with Distributed Antenna Systems

Our Distributed Antenna Systems (DAS) are networks of spatially separated antennas connected to a common source, designed to enhance wireless service within specific areas. By distributing the signal, DAS improve coverage and capacity in locations with high user density or areas where traditional antennas struggle to provide adequate service, such as large buildings and tunnels.

MENURA

MENURA is a next-generation repeater and DAS platform designed for mission-critical communication infrastructures.

RUD-5

The RUD-5 is a versatile radio repeater designed to enhance radio coverage across various networks.

COSweb

COSweb is a Network Management System that provides real-time visibility, remote control, and lifecycle management.
