Telecommunications has evolved from a coper network carrying predominantly voice traffic, to include radio based equipment handling voice but dominated by data traffic. The sheer number of users and the advent of smart phones require the network to continually evolve, equipment that was once housed indoors in forced air cooled racks is now packaged in RRUs (remote radio units) mounted outdoors and cooled by natural convection.
This outdoor equipment has increased power amplifiers in smaller enclosures. Discrete platforms, such as Telecom, TV, and IP networks are converging into a single connected infrastructure. The reliability of equipment deployed as part of this infrastructure is critical and temperature control has a direct relationship to this reliability.
Columbia-Staver has been involved in providing Thermal solutions throughout this entire transition and can offer bespoke solutions for indoor and outdoor applications, including compliance and survival of salt/fog and freeze-thaw conditions.
Columbia-Staver have technologies that can be applied to individual components, multiple components at a board level and even entire systems. Solutions for Telecommunications are currently deployed in base stations, micro base stations, repeaters, amplifiers, enclosures, optical equipment, central office equipment and consumer premises equipment such as TVs, set-top boxes and Internet gateway devices.
