The RASUM 8.33 project, undertaken by DFS, the German air navigation service provider, has reached a successful conclusion. Initiated in 2010, this nationwide modernization effort focused on upgrading radio technology across nearly 100 radio sites, encompassing approximately 4,000 radios. These sites are interconnected with the four DFS control centers and 15 designated international German airports under DFS jurisdiction.
The final phase of the project was marked by the activation of the last radio station in Auderath, located in Rhineland-Palatinate, thereby completing the comprehensive modernization initiative. DFS has significantly enhanced aeronautical radio coverage throughout Germany through the installation of independent and redundant telecommunications connections, along with the implementation of new antenna systems. Additionally, the project involved the renewal and standardization of buildings and infrastructure at the various radio sites.
Commenting on the project, Friedrich-Wilhelm Menge, Chief Technology Officer on the DFS Executive Board, said: « The modernised sites will enable DFS to meet new challenges, such as voice transmission via Voice-over-IP (VoIP). »
VoIP, or Voice over Internet Protocol, is a technology facilitating the transmission of voice communication over IP networks. Differing from traditional analog systems, VoIP provides superior voice quality and enhanced scalability.
DFS is aligning with Commission Implementing Regulation (EU) No 1079/2012 by converting radio sites to the new 8.33-kilohertz channel spacing. The objective is to address the frequency shortage in Europe by minimizing channel spacing.
The radio technology for this initiative was provided by the Rohde & Schwarz technology group.
