The power level of a system or a signal chain is one of the main indicators to guarantee a reliably signal integrity with a sufficient signal-to noise-ratio. Despite effects like a standing wave, were the voltage and current varies along a cable, the power stays always constant and is therefore a much useful quantity for judging high frequencies transmission lines.

Utilizing DEV Systemtechnik’s advanced optical and coaxial RF systems Qvest Media has planned and integrated WELT’s state of the art satellite infrastructure in the new WELT HQ in Berlin.

Ever increasing demand for more bandwidth in the terrestrial wireline and wireless domain on a global scale and the requirement for ubiquitous broadband network access pose significant challenges as well as chances for satellite network operators.

Whether in a cable headend, earth station or teleport, reliable signal transmission and distribution is the backbone of a facility’s successful operation. From signal reception at the satellite dish, to processing and distribution within a facility, and final distribution, signal quality availability must be properly engineered and managed. Redundancies play a key role in order to guarantee maximum reliability and uptime.

Etisalat, one of the largest telecommunications companies in the world and the leading operator in the Middle East and Africa, wished to expand an existing CATV head-end in UAE by adding a 700-channel IPTV system. The order to supply the system went to the Chinese telecommunications group Huawei. For the critical system segment from the antenna to the receiver, Huawei relies on products and services of DEV Systemtechnik.
