Kenya Relies On Frequency Management Solutions From Rohde & Schwarz

The Communications Authority of Kenya (CAK) has commissioned Rohde & Schwarz to implement a spectrum management and monitoring system (SMMS). The solution, which consists of mobile and stationary components, will help the CAK regulate the radio spectrum to ensure interference-free reception of services such as radio, TV and wireless communications.

The CAK has awarded Rohde & Schwarz a contract to upgrade and expand the country's spectrum management infrastructure. Rohde & Schwarz will also provide training and maintenance services. The nationwide system will be delivered and implemented by the beginning of 2016. In the future, the HF/ VHF and UHF frequency spectrum will be monitored from eleven stationary monitoring and direction finding (DF) stations. Four all-road vehicles will also be equipped in order to extend the range of the DF base and fix the position of radio interferers while moving. The system is centrally controlled from Nairobi; an additional regional operation center is located in Mombasa.

Through effective frequency management, the CAK can detect and prevent interference in radiocommunications services. This is achieved by monitoring the electromagnetic spectrum and locating the position of suspect signals. The R&S UMS300, from the R&S UMS family of universal monitoring systems, accomplishes these tasks quickly and reliably. It is the core of the new Rohde & Schwarz installation in Kenya. The R&S UMS300 system is enclosed in a compact weatherproof housing and can be mounted directly on top of the antenna mast. The resulting high system sensitivity makes it possible to precisely locate even weak signals and expands the detection range. Installation on masts or roofs also reduces infrastructure requirements. Mounting the hardware at a certain height makes it harder to reach, reducing the risk of damage and theft.

The Kenyan regulatory authority acquired their first Rohde & Schwarz system in 1986, and it is still operational today. The system solutions from Rohde & Schwarz meet all the relevant requirements and recommendations of the International Telecommunication Union (ITU), a United Nations (UN) body that regulates the use of frequencies. Rohde & Schwarz has been globally successful in the field of spectrum monitoring for decades.
