ATDI announces a significant upgrade to AI Mask Prediction, its intelligent tool for refining cartographic data. This new release marks a leap forward in map automation, driven by a state-of-the-art deep learning architecture that delivers over 93% accuracy across continental regions.
AI Mask Prediction now directly detects, from satellite imagery, trees and buildings likely to cause radio signal diffraction, enabling RF planners to build more accurate models from the outset. The enhanced model improves on the original by offering faster and more precise data extraction, thereby boosting the quality of coverage predictions, interference analysis, and network optimisation.
A key benefit is that it runs efficiently on both CPUs and GPUs, making it accessible even with low-spec hardware. Combined with the ability to generate high-resolution maps in-house, this tool helps reduce manual workload and provides precise, current inputs for RF planning and optimisation.
This powerful update is now available in the latest version of HTZ, helping engineers enhance accuracy and model with confidence.

Wind turbines can interfere with radar systems, posing challenges for aviation and defence operations. This video outlines a structured, EUROCONTROL-based methodology for assessing such impacts. The two-phase process begins with a quick screening to determine potential interference based on turbine height, distance, and line of sight. If needed, a detailed technical evaluation follows, including propagation modelling and radar performance analysis. This phased approach enables stakeholders, including regulators, radar operators, and wind farm operators, to identify risks early and implement effective mitigation strategies. It ensures radar integrity while supporting the safe expansion of renewable energy infrastructure.

As one of the UK’s busiest waterways, the Port of London depends on reliable AIS coverage to manage vessel traffic. With riverside developments on the rise, the Port of London Authority (PLA) commissioned ATDI to assess the potential impact on AIS performance.
Using HTZ Communications, ATDI modelled signal obstructions and proposed mitigation strategies such as optimised site placement and antenna adjustments. The study compared modelled results with known performance baselines to validate coverage resilience under real-world conditions.
The final report provides technical assurance to the PLA and supports informed discussions with planners. The complete project file was delivered to the Authority, enabling future updates using their licensed HTZ software.

Artificial Intelligence is transforming how we design and manage radio communications. From predicting coverage to automating interference analysis, AI is helping network operators, regulators, and researchers optimise performance and speed up decision-making.
A great example comes from Stellenbosch University in South Africa, where a postgraduate researcher is using HTZ Communications to generate thousands of RF coverage maps for training a machine learning model. The study explores how simplified radio zone maps, analysed with generative adversarial networks (GANs), can predict radio coverage without relying on complex base map data. The project utilises advanced propagation models, such as ITU-R P.526, and high-resolution terrain data to simulate realistic conditions across various environments.
This academic study shows how HTZ can support innovative applications beyond traditional planning, reinforcing its flexibility and value in AI-driven research.
ATDI continues to invest in AI to enhance RF planning. Our AI-powered radio signal identification model accelerates real-time spectrum analysis by automatically classifying signals, eliminating the need for human input. Meanwhile, the AI Mask Prediction feature extracts detailed cartographic data from satellite imagery and terrain maps, ensuring better accuracy in network simulations.
As the sector shifts toward more innovative, more adaptive systems, integrating AI into tools like HTZ will play a critical role in shaping the next generation of connected, mission-critical communications.

ATDI recently returned from Middle East Rail in Dubai, where we connected with infrastructure operators, regulators, and technology providers from across the region. As rail networks expand and modernise, the industry faces increasing complexity, particularly in managing mission-critical communications that are both reliable and future-proof.
A key topic of discussion was the transition from legacy technologies, such as GSM-R and TETRA, to next-generation platforms, including LTE-R and FRMCS. This shift presents challenges related to interoperability, spectrum coexistence, and the performance of hybrid networks operating across diverse environments—from open countryside to tunnels, bridges, and densely populated urban areas.
At the event, ATDI showcased how our flagship tool, HTZ Communications, enables rail operators to manage the full lifecycle of radio network planning and optimisation. Its versatility allows engineers to work across multiple technologies—DMR, TETRA, P25, LTE-R, FRMCS within a single project, streamlining planning, reducing coverage gaps, and ensuring systems meet both operational and regulatory demands.
