Three-Legged Communication Tower: A Model of Technological Innovation and Engineering Practice

As a core component of modern communication infrastructure, the three-legged communication tower plays a pivotal role in 5G network deployment due to its structural stability, material durability, and environmental adaptability. Its design integrates mechanical optimization with aesthetic considerations, making it the preferred solution for urban and mountainous communication coverage.

Featuring an equilateral triangular configuration, the tripod tower exhibits a low wind load coefficient and withstands winds up to Category 11, making it particularly suitable for windy and sandy regions. The tower sections connect via external flanges, with tension-loaded bolts reducing maintenance costs. The innovative three-leaf foundation further minimizes land use and construction expenses. Additionally, the tower surface undergoes anti-rust and anti-corrosion spraying, with customizable colors to blend into the surrounding environment.
In complex mountainous terrain, the tripod tower resolves site leveling challenges through stepped or anchored foundations. For instance, a mountainous project requiring 35 tower installations on slopes ranging from 20° to 45% effectively addressed transportation constraints and elevated work risks with its tripod design. Along high-speed rail lines, their high stability proves invaluable. For instance, in the Xi'an-Chengdu High-Speed Railway communication tower renovation project, three-legged tubular towers enhanced flood season safety through the “boot replacement” initiative (replacing corroded tower boots).
In the transition from “communication towers” to “digital towers,” three-legged tubular towers support smart city and emergency communication scenarios. Fujian Tower deployed 97% of its 5G base stations on such towers through shared infrastructure, significantly reducing industry investment. Looking ahead, as 6G technology evolves, their modular design may further adapt to higher frequency band requirements.
