Mobile towers, also known as cell towers, are an essential part of the modern communication network infrastructure. They are used for the transmission and receive wireless signals for mobile phones, internet services, and other wireless devices. The construction and placement of mobile towers fall under the purview of civil engineering, as it involves the design, construction, and maintenance of the physical infrastructure. Civil engineers are responsible for the selection of the site, foundation design, and structural design of the tower. They supervise the construction process to ensure the tower is built according to the specifications and meet up the safety standards. In addition to civil engineering, other areas of expertise are required for the installation of mobile towers. These include electrical engineering, telecommunications engineering, and environmental engineering. Electrical engineers are responsible for designing and installing the electrical systems, including the power supply and backup systems.
