Communication site maintenance services maintain remote communication sites and client-owned (CO) infrastructure and equipment. They perform preventive maintenance and/or corrective maintenance and differ in terms of capabilities. Some communication site maintenance services manage antenna sites for wireless communications providers. These communication site maintenance services specialize in technologies such as high definition television (HDTV), local multi-point distribution service (LMDS), wireless fidelity (WiFi), broadband, and point-to-point or point-to-multipoint networks. Wireless systems consist of integrated radio frequency (RF) components such as transmitters, receivers, transceivers, converters, antennas, and antenna positioners. Adherence to WiFi compatibility standards ensures that all wireless devices comply with IEEE 802.11, a specification for wireless communications from the Institute of Electrical and Electronics Engineers (IEEE).
Communication site maintenance services test, maintain and repair copper cables and fiber optic cables, wireless networks and bridges, and lighting protection and grounding systems. Communication site maintenance services may also repair lighting controllers, microwave antennas, and very small aperture terminal (VSAT) systems. Companies that take field strength readings and perform wave propagation modeling are also available. Cable testing services test existing lengths of copper cable for insertion loss, fault loss and return loss. They may also replace damaged cables and test standing wave ratio (SWR) antennas. Tower inspection services audit and inspect cell phone towers, very high frequency (VHF) towers, and other types of communication towers. In the United States, these companies can help clients comply with regulations from the Occupational Safety and Health Administration (OSHA), the Federal Aviation Administration (FAA), and the Federal Communications Commission (FCC).
Communication site maintenance services who advise clients about site acquisition specialize in network expansion or network deployment projects. They develop detailed site surveys with photographs, blueprints, and models for cell phone companies and other communications providers. Communication site maintenance services that can recommend the selection of additional networking equipment and communications towers are also available. Network equipment includes devices such as wireless hubs, routers, gateways, and repeaters. Communications towers are support structures that provide a line of sight for viewing and facilitate the transmission and reception of signals. They are usually made of aluminum, copper, steel, stainless steel, plastic or wood.
