Recently, Lintratek Technology successfully completed a commercial mobile signal booster project in the underground levels of a wastewater treatment plant in Beijing. This facility features three underground floors and required strong mobile signal coverage across approximately 2,000 square meters, including offices, corridors, and staircases.
This isn’t Lintratek’s first venture into underground infrastructure—our team has already delivered stable mobile signal coverage for similar wastewater facilities in multiple Chinese cities. But why do wastewater plants need to be built so deep underground?
The answer lies in urban sustainability. Building downward helps cities preserve valuable surface land, contain gas and noise pollution, and minimize the impact on surrounding residents. In fact, some cities have transformed the surface area above these plants into public parks, showing how advanced engineering can coexist with urban living.
High-Performance Signal Solution for Deep Urban Infrastructure
After reviewing the architectural blueprints sent by the client, Lintratek’s technical team swiftly developed a comprehensive DAS (Distributed Antenna System) plan centered on a high-power commercial mobile signal booster. The solution featured a 35dBm (3W) dual-5G + 4G booster, equipped with AGC (Automatic Gain Control) and MGC (Manual Gain Control) to ensure a stable, high-speed 5G experience—crucial for a public service facility like a wastewater treatment plant.
Commercial 4G 5G Mobile Signal Booster
To capture and transmit outdoor signals, we deployed log-periodic antennas externally. Inside, we installed 15 high-gain ceiling antennas strategically in stairwells and corridors, ensuring signal penetration into every office space.
Two Days to Complete, Eight Days from Start to Finish
Lintratek’s experienced installation team completed the entire deployment and tuning process in just two days. On the very day of project completion, the system passed the final acceptance test. From the first client meeting to full signal deployment, the entire process took only 8 working days—a testament to Lintratek’s engineering expertise, agile team coordination, and reliable product quality.
