These days, strong mobile network coverage isn’t just about city streets and high-rises. The real test lies underground, in tunnels, deep mountains, and hard-to-reach spots. That’s where reliable signal solutions make all the difference.

 

One recent major project stands out: the 2.8-kilometer Airport East Line of Shenzhen Metro Line 20. It’s a key part of the expansion for Shenzhen Airport’s T4 terminal, handling passenger transfers and local commuter traffic. The requirements were extremely high: rock-solid stability, large-capacity data transmission, and seamless signal coverage with zero dead zones.

Metro tunnels are one of the hardest environments for cellular signals. They’re fully enclosed, so signals fade extremely fast and dead zones are common. Construction has to align with civil engineering work, with no room for mistakes or rework. On top of that, high-voltage power lines create strong electromagnetic interference. It’s a top-tier communication challenge.

To tackle this, we relied on 14 years of technical experience and our self-developed fiber-based signal repeater system. It’s built with smart adaptation, high-power anti-interference, and stable energy efficiency—three core strengths that directly solve tunnel communication pain points.
 
 
For this metro project, we used a phased deployment strategy with custom panel antennas, delivering seamless coverage along the entire 2.8km tunnel. After on-site testing, calls were crystal clear, and data connections stayed smooth. The system not only met communication needs during construction but also laid a stable foundation for long-term daily operations.

Our work didn’t stop at designing the tech. From initial site surveys and custom solution design, to equipment installation, tuning, and optimization, our team stayed fully involved. We proactively avoided complex electromagnetic interference around the airport, delivering efficient, professional service that earned the client’s trust.
