In line with its procurement guidelines, the Peruvian Ministry of Transportation and Communications – Ministerio des Transportes y Comunicaciones (MTC) – commissioned Rohde & Schwarz to deliver and install a country-wide system for monitoring the frequency spectrum. A total of 30 stationary and mobile units are interconnected and used for frequency management throughout Peru.

In 2015 and 2016, Rohde & Schwarz put one stationary and one mobile measurement and direction finding system into operation at each of 15 different cities throughout Peru. The MTC uses the equipment to regulate and monitor the frequency spectrum, specifically to ensure interference-free reception of radiocommunications services. The system is suitable for use in Peru's different climate zones. It is used in areas ranging from the desert regions on the Pacific to the Andean highlands.

The core of the new system is the compact R&S UMS300 monitoring and radiolocation system from the R&S UMS family of universal monitoring systems. The system features rugged housing for outdoor installation on the antenna mast, greatly increasing the sensitivity of the system. Installation on masts or roofs also reduces infrastructure requirements. The stations are controlled using the R&S ARGUS spectrum monitoring software, which supports various operating modes. The system offers interactive operation or fully automatic test sequences and can be run in local mode or via remote control.
