China has recently launched a national initiative titled “Signal Upgrade”, aimed at significantly enhancing mobile network coverage in key public service sectors. The policy prioritizes deep coverage in critical infrastructure including office buildings, power substations, transportation hubs, schools, hospitals, and water utilities.
Key aspects of the campaign include:
· Targeting signal blind zones in vital industries and public service facilities
· Expanding 5G signal deep coverage into underground, indoor, and remote rural areas
· Strengthening telecom infrastructure in sectors like electricity and emergency response
Power substations, as the lifeblood of urban energy systems, are central to this effort. Reliable mobile signal coverage is essential not only for real-time monitoring and operational efficiency, but also for the safety and stability of city infrastructure.
Lintratek: A Trusted Force in Communication Infrastructure
With over 13 years of experience in mobile signal technology, Lintratek is a national high-tech enterprise specializing in commercial mobile signal boosters, fiber optic repeaters, and DAS (Distributed Antenna Systems). From equipment manufacturing and solution design to on-site implementation, Lintratek provides end-to-end services for complex signal coverage projects.
Long before the Signal Upgrade initiative, Lintratek had been actively involved in public infrastructure signal enhancement—particularly in power substations. The company has completed multiple successful deployments, setting a benchmark for scalable, high-performance signal coverage.
Case Studies: Lintratek’s Commercial Signal Booster Solutions for Substations
Case 1: Wind-Resistant Signal Coverage in Inner Mongolia Substation
Site Size: 2,000 m²
Challenge: Strong winds and reinforced concrete walls with metal cladding blocked indoor signals.
kw37 commercial mobile signal booster
Solution:
· Installed 5W dual-band commercial mobile signal booster for stable signal source
· Deployed wind-resistant outdoor log-periodic antennas to receive base station signals
· Used 20 indoor ceiling antennas for full signal coverage
· Result: All three major mobile operators achieved full bars; voice and data signals became stable and clear.

Case 2: Multi-Site Urban Substation Coverage
Challenge: Communication disruption due to reinforced concrete and high-voltage electromagnetic interference across 8 urban substations
Solution:
Customized High Power Gain Mobile Signal Booster configuration based on station size:
· 1 × 5W tri-band fiber optic repeater (large site)
· 4 × 3W tri-band boosters (medium sites)
· 3 × 500mW amplifiers (small sites)
· Combined ceiling antennas and panel antennas for wall-penetrating coverage
Result: 7 sites completed within 2 weeks; three-network coverage stabilized, ensuring uninterrupted emergency communications.
Case 3: Full 5G Signal Coverage in Suburban Office Building
Site: 2,000 m² office building at a suburban substation
Challenge: Long distance from base station and interior walls caused 4G/5G dead zones
KW35A 4G 5G commercial Mobile Signal Booster
Solution:
· Deployed KW35 enterprise-grade commercial mobile signal booster (35dBm, dual 5G band support)
· DAS layout with hidden ceiling antennas in corridors and directional antennas in partitioned areas
· Result: Installation completed in 1 day; full 4G/5G signal coverage across the office building, passing performance tests the next day.
Each project illustrates Lintratek’s strategy of pinpointing challenges, customizing technical solutions, and delivering fast, scalable deployment—all powered by reliable commercial mobile signal booster technology.
