Supporting facilities refer to the auxiliary infrastructure that ensures the smooth operation of towers and related systems. These facilities include power supplies, cooling systems, backup generators, and equipment shelters. Unlike the towers themselves, which are visible and often iconic, supporting facilities operate behind the scenes to maintain functionality and reliability. They are essential for both transmission and telecommunication towers, providing the necessary resources to keep systems running 24/7. Supporting facilities are designed with redundancy and efficiency in mind, ensuring that any disruptions are minimized. Their role is critical in maintaining the integrity and performance of the entire network, making them an indispensable part of modern infrastructure.
