The world of air traffic management relies heavily on seamless and high-quality voice communication to ensure safety and efficiency. Rohde & Schwarz has successfully deployed its cutting-edge R&S AVQA advanced voice quality assurance system, now operational with ANS Czech Republic. This innovative solution is set to revolutionize VoIP quality monitoring, providing unmatched reliability and precision for Czech air traffic control. With R&S AVQA, the skies over the Czech Republic just became clearer and safer.
A New Era in Voice Communication Monitoring
In the fast-paced and high-stakes world of air traffic management, every word counts. Clear, uninterrupted voice communication can make the difference between smooth operations and critical delays. That’s why the recent deployment of the R&S AVQA advanced voice quality assurance system by Rohde & Schwarz for Air Navigation Services of the Czech Republic (ANS CR) marks a significant leap forward. With this cutting-edge technology, the Czech Republic’s air traffic control is ushering in a new era of reliability, precision, and safety.
Why Voice Quality Matters More Than Ever
Voice over IP (VoIP) has revolutionized communication in air traffic management. However, its reliability is only as strong as the systems that monitor it. Traditional network monitoring tools often fall short, focusing narrowly on general IP parameters and missing critical insights into the actual voice experience.
For air navigation service providers like ANS CR, maintaining top-tier voice quality isn’t just a technical goal—it’s a safety imperative. The introduction of R&S AVQA ensures that every spoken instruction, alert, and update is transmitted clearly and reliably.
What Makes R&S AVQA Different?
Unlike conventional tools, R&S AVQA was designed specifically with the aviation sector in mind. It delivers real-time insights into the parameters that directly affect voice quality, based on the ED137 standard—the benchmark for VoIP in air traffic control.
This means users can quickly detect and resolve impairments, especially during the testing and implementation phases of new VoIP systems. No more time-consuming guesswork or combing through generic IP stream data. Instead, ANS CR’s team gets a precise, comprehensive view of their network’s voice performance at any given moment.
A Smooth and Timely Deployment
The path to this deployment was as efficient as the system itself. It began with a contract signed on January 31, 2024, and concluded with final acceptance just nine months later, on October 31, 2024.
Pavel Salanda, Managing Director of Rohde & Schwarz Czechia, emphasized the significance of this achievement. “This project not only underscores Rohde & Schwarz’ commitment to delivering innovative solutions but also highlights our dedication to meeting the evolving needs of the aviation industry.”
Indeed, the speed and precision of the deployment reflect the very values the AVQA system is built upon.
A Game-Changer for ANS CR
For ANS CR, the implementation of R&S AVQA is more than just a technical upgrade—it’s a strategic enhancement. As CEO Jan Klas explains, “I cannot imagine rolling out new Voice over IP systems without such a diagnostic system. With R&S AVQA, we will be able to maintain optimal voice quality effortlessly.”
This new capability empowers ANS CR to stay ahead of communication issues, ensuring that air traffic controllers can do their jobs with maximum confidence and efficiency.
Part of a Broader Vision
R&S AVQA isn’t a standalone tool—it’s part of the CERTIUM® Analysis portfolio from Rohde & Schwarz, a suite of solutions tailored to modernize and optimize air navigation services. Within this context, AVQA emerges as an almost indispensable asset.
Its integration into ANS CR’s infrastructure reflects a broader industry shift toward more intelligent, automated monitoring systems that can adapt to increasing traffic volumes and complex operational demands.
Designed with You in Mind
As a reader, you might be wondering what this all means for you. If you’re an aviation professional, it means a more reliable communication environment that helps safeguard your operations. If you’re a traveler, it translates to safer skies and smoother journeys.
At its core, the deployment of R&S AVQA signals a commitment—not just to innovation, but to the people who rely on aviation systems every day. Whether you’re behind the controls or on board a flight, clear communication is a shared concern, and technologies like AVQA are making it more robust than ever.
A Promising Future for Air Traffic Communication
With R&S AVQA now fully operational, ANS CR is better equipped to face the challenges of modern air traffic management. The system’s intelligent diagnostics, real-time monitoring, and seamless integration offer a template for future-ready communication infrastructure.
More than a technical achievement, this deployment represents a commitment to excellence—from Rohde & Schwarz, from ANS CR, and from an industry that understands the value of every word spoken across the airwaves.
As airspace becomes more crowded and operations more complex, one thing is certain: systems like AVQA will be central to keeping the skies safe, secure, and connected.
