Access to sensor data and communication is critical for success in combat environments. The battlefield poses challenges such as information overload, non-integrated data, rapidly changing circumstances, and uncertainty caused by missing information. Overcoming these challenges is a key objective for defence organisations. Our network concept goes beyond formal military air traffic management and command centres, enabling secure tactical data exchange between operators and diverse military units. Network-enabled capabilities are essential for modern military operations, supporting coordinated decision-making based on fast, reliable information and communication systems.

Strengthening air defence through connected intelligence

To counter increasingly complex airborne threats – from unmanned aerial systems to hypersonic missiles – defence organisations rely on a wide range of surveillance sensors and command systems. The challenge lies not only in collecting data, but in securely sharing, fusing, and distributing relevant information across national boundaries, domains, and coalition partners. Frequentis enables holistic air defence networks that connect heterogeneous sensor landscapes into a coherent, resilient information environment. By decoupling sensors from proprietary technologies and supporting standardised as well as proprietary interfaces, our solutions give defence forces flexibility, interoperability, and long-term investment protection. 

Multi-sensor data fusion for a trusted air picture 

At the core of an effective air defence network is intelligent multi-sensor data fusion. Information from diverse sources – including stationary and mobile radar systems, next-generation sensor technologies, air situation calculations, and tactical data links – is combined into a consistent, high-quality air picture. Advanced processing and automation support higher-level functions such as classification, correlation, and user-specific information delivery. This enables faster, better-informed decisions while reducing operator workload and information overload. 

Secure information exchange across domains and partners

 Air defence operations demand strict control over who receives what information, at what level of detail, and under what security conditions. Frequentis network concepts implement security gradients and controlled data exchange, ensuring that information is shared strictly according to operational role, mission context, and national or multinational agreements. Data sanitisation, filtering, and policy-based distribution enable secure cross-border and cross-domain cooperation – while protecting sensitive and classified information at all times. 

Resilient, application-aware defence networks

 Modern air defence networks must operate reliably across heterogeneous infrastructures, combining stationary and deployable assets, multiple transport technologies, and varying bandwidth conditions. Frequentis solutions apply application-aware routing and intelligent traffic prioritisation to ensure mission-critical data is delivered with predictable performance. Even under degraded network conditions, the system adapts dynamically – prioritising relevant information, minimising latency, and maintaining operational continuity. 

Built for evolution and operational control

Frequentis air defence networks are designed to evolve alongside changing threat environments and technology landscapes. Centralised, system-wide management supports efficient configuration, monitoring, and maintenance across distributed sites and user groups. By harmonising diverse sensors and command systems into a single managed network, defence organisations can concentrate expertise where it matters most – while maintaining full visibility and control across the entire operational environment. 

Proven capabilities for national and multinational defence

Frequentis brings decades of experience in military communication and surveillance networks. Deployments such as MilRADNET, the nationwide sensor network for the German Armed Forces, demonstrate the ability to deliver resilient, interoperable solutions that enhance safety, situational awareness, and collective defence across national and allied airspace.
