Railway / Tunnel Coverage

People nowadays require an uninterrupted and high capacity wireless experience when commuting on trains and subways. The seamless performance requirement poses a big challenge to operator especially on high speed railway. For instance, poor design at handover points may cause dropped calls or disconnection from the internet. Additionally, equipment installed in underground tunnels are subjected to high temperature conditions. Hence, good system design with high specification equipment is the only option.


Comba DAS solutions are specifically designed for tunnel environments to ensure a robust and optimal wireless network. Other features include smaller footprints and specialized chassis designs to help ease of maintenance and hassle-free implementation.

Comflex DAS is the main component of Comba’s railway/tunnel coverage solution.
