This month’s developments highlight a shift towards more intelligent, data-driven spectrum engineering.
The April 2026 update to HTZ Communications enhances interference analysis and coverage modelling, enabling engineers to better manage complex RF environments and improve decision-making across the network lifecycle.
Updated map data delivers higher-resolution terrain and clutter datasets, increasing ATDI’s partnership with the Florida Division of Emergency Management, which demonstrates this in practice, using HTZ Communications to strengthen resilient emergency response networks.
Discover how ATDI enables defence organisations to move from reactive spectrum management to real-time operational control. To learn more or arrange a discussion, contact our team or book a meeting at one of our upcoming defence events.
Alongside this, upcoming industry events continue to address the growing challenges of spectrum congestion, interference, and operational performance.

Florida Division of Emergency Management selects HTZ CommunicationsThe Florida Division of Emergency Management (FDEM) has selected HTZ Communications to support statewide public safety network planning and frequency optimisation. The decision was driven by the need to strengthen interoperability and provide public safety stakeholders with a comprehensive radio planning capability.
Florida presents a complex operating environment, combining densely populated urban areas with wide rural and coastal regions. Ensuring consistent radio coverage across these different environments requires careful engineering and effective spectrum coordination.
HTZ Communications enables engineers to model and manage multiple radio technologies within a single project environment. This capability allows FDEM to evaluate coverage, optimise frequency assignments, and assess potential interference between systems across the state, helping to ensure reliable communications for emergency responders and public safety agencies.

Witness how ATDI combines HTZ Warfare and ICS Monitoring to create a continuous loop between modelling and real-time operations, enabling engineers to simulate complex environments, validate assumptions using live spectrum data, detect hostile emitters, and assess the impact of jamming before execution. The result is faster, more coordinated decision-making when it matters most, reducing risk and improving confidence in operational outcomes.
ATDI will demonstrate this capability live at Eurosatory and AOC Europe, where attendees can see how spectrum intelligence is embedded directly into operational workflows to minimise the risk of interference and protect mission-critical communications.

As wind energy projects expand, so does the need to understand their impact on airport radar systems. Wind turbines can introduce clutter, false targets, and tracking instability, affecting both primary and secondary surveillance radars.
Delivered in collaboration with CANSO, this recorded webinar provides a technical overview of wind turbine interference, its impact on PSR and SSR systems, and the operational challenges it creates. It compares screening approaches, including the EUROCONTROL framework, with detailed modelling techniques for accurate impact assessment.
The session concludes with practical mitigation strategies to help balance renewable energy development with airspace safety and radar integrity.
