Rohde & Schwarz, a global leader in TV & radio terrestrial transmission has announced a strategic contract win with the Egyptian National Media Authority (ENMA). In what represents the second phase of a major DVB-T2 network expansion in one of Africa’s largest and most populous countries, Rohde & Schwarz will equip multiple transmission sites with its state-of-art R&S TMU9evo DVB-T2 transmitters.
Working with local partner, Cairo-based Integrated Communication Systems, Rohde & Schwarz is supplying, installing, and commissioning a comprehensive multi-vendor technology solution across seven sites throughout Egypt. Operating in Doherty mode, the TMU9evo transmitters achieve up to 40% energy efficiency and offer market-leading on-air time. At three sites, the transmitters will be fitted with 1Kw dual exciters and at the remaining four the transmitters are fitted with 500W exciters in 1+1 configuration. Also, Rohde & Schwarz will supply R&S ETL DTV Analysers and R&S PRISMON Multiviewer systems to monitor and analyse video signals throughout the distribution workflow.
Other equipment includes Spinner Bandpass Filter & Dummy Load, Com-Tech Indoor Coaxial Equipment such as Ulink Patch panels, Power Meters and Rigid Lines; Program Input Equipment from various suppliers, Moller Preussler, Automatic Voltage Regulator & Low Power Distribution Boards, Jampro DTV Antenna Systems and RFS Main Feeder & Dehydrator equipment.
“ENMA selected Rohde & Schwarz for this demanding project after careful evaluation of several tech vendors’ proposals. The success of this project is critical for us and we have been satisfied with the reliability of R&S systems delivered as part of the first phase as well as the high quality of the services they have provided us,” commented Engineer Maysa Kamel, Chairman of Broadcasting Engineering Sector at ENMA.
“A key factor influencing our decision is the advanced design of the TMU9evo transmitter. It provides high energy efficiency combined with advanced wideband amplifier architecture and superior thermal design for very long-term stable operation at 45°C. The transmitter is proven to offer best in class signal quality, more than – 37dB MER and this remains constant over many year’s operation. The transmitter employs market leading adaptive pre-correction technology within a system architecture that is focused on long product lifetime. It utilizes high quality RF components and features an innovative thermal design, which avoids hot spots and thermal stress,” commented Engineer Ahmed Abdelmohsen, Head of Transmission Projects Department at ENMA.
