This month’s update brings together key product developments, project highlights, and company news.
We start with the latest HTZ and map data updates, including new features and improvements. A wargaming demo from Statalignment shows how a 5G Tactical Edge network can restore coverage when the communications infrastructure is compromised. In the scenario, a fixed base station destroyed by a drone strike is replaced with a Tactical Edge 5G base station deployed alongside the unit. This approach requires spectrum coordination with the local MNO. Once activated, the node rapidly restores critical connectivity in the area.
We also highlight WSP’s use of HTZ Communications to deliver robust railway comms systems. In corporate news, ATDI Inc. has opened a new office in Washington to support growth across North America.
Our 'News in Brief' section features recent work with DSTL and continued support for the Red Cross. We also share highlights from recent events and a look ahead.
Thank you for reading — and as always, get in touch with any questions or feedback.
HTZ V2025-11 and above – Feature Enhancements Now AvailableHTZ continues to evolve, with new features and modifications designed to enhance the user experience, improve RF analysis capabilities, and support critical spectrum management tasks.
Interface:
Import Stations – ITU Emission Code: Now supports the “ITU emission” field when importing generic stations or subscribers. Automatically updates Tx/Rx bandwidths based on ITU emission codes.
Object Labels – Microwave Channel Name: Microwave channel names are now included in the label options under Object Properties (F5).
Area File – Extended Postcode Support: CSV import now accepts postcode values up to 9,999,999,999.
Multimap – Multi-Threaded Performance: Multimap operations are now multi-threaded, offering faster execution for large-scale views.
Coverage Export – Limit Distance: New “Limit distance” option lets users control matrix export size by defining a custom radius, regardless of coverage area.
Cartography – India Projection Added: EPSG:7755 (WGS 84 / India NSF LCC) has been added to the cartographic projection library.
Polyline Tools – Distance Display: <b>/<e> short keys now show cumulative distance along each polyline segment; up to 50 vertices per polyline.

Object Labels – Smart Colour Selection: Labels in transparent mode now automatically select black or white text based on the background brightness for improved readability.
Spectrum Management:
Spectrum Availability Map Export: Each frequency now exports a binary coverage map (.RFL) showing used vs. unused channels. Useful for quick visualisation of spectrum occupancy.
Wind Turbine Footprint Mode: A New option has been added to define building footprint radius as either mast diameter or the greater of mast/ blade size, improving DTM/Building conversion accuracy.
Visibility Maps – Negative DTM Support: Visibility calculations now support DTMs with negative elevations. AGL reference is recommended for result interpretation.
Aeronautical Threshold Parameter: A New “Threshold (m)” field has been added to the station site tab to support accurate BRA/BRA 3D runway threshold settings for aeronautical stations.
ICS Manager noDB – New Version: The latest version (v2025.10.02) is now bundled with the installation package.
Calculations:
Interference Mode – 2nd Best Server: New option in C/I interference mode considers interference on the second-best server, even if the best server is not affected.
Visibility Maps – Negative DTM Support: Visibility calculations now support DTMs with negative elevations. AGL reference is recommended for result interpretation.
Clutter Model – Reciprocal dB/km Losses: The “dB/km” model now provides reciprocal losses for downlink and uplink, improving accuracy between base station and subscriber.
Propagation – ITU-R P.530-19 Update: ITU-R P.530-19 has replaced P.530-18 in reliability calculations for more current propagation modelling.
Variable Height Coverage – Export CFDm: Exports variable-antenna-height coverage to CFDm format for height-based network analysis.
Propagation – ITU-R P.1812-8 Update: ITU-R P.1812-8 replaces P.1812-7 for more accurate propagation predictions in complex terrains.
Variable Height Coverage – Polygon Limitation: Coverage calculations can now be restricted to defined vector polygons using a new toggle option.
Ground Reflections – Angle Error Setting: Reflection modelling now allows users to define an angle error range for enhanced multipath simulation.
Multipath C/I Map: A New feature creates C/I maps that account for interference from reflected (multipath) signals using a specular 3D model.
CCTV Coverage – D.R.I Support: D.R.I (Detection, Recognition, Identification) mapping is now available for CCTV coverage, with new map display and legend.
Radiocoms:
Antenna Patterns – ITU-R M.1851-2 Support: Cosecant squared antenna pattern added for mobile and radar systems. Available under “Patterns” with preset ThetaStart.
Radar Sensitivity – User Defined: Radar receiver sensitivity (dBm) is now user configurable, automatically updating R/R0 and threshold values via the Radar equation.
New High-Resolution Map Data Available for DownloadAs part of your maintenance contract, you have exclusive access to ATDI’s continually updated map data library, an essential resource for accurate and efficient network planning.
Our latest release features royalty-free cartographic datasets, now accessible through the customer portal. These high-quality datasets enhance your planning accuracy and eliminate the cost and effort of sourcing third-party data.
What’s new this month?
Here’s a summary of newly added or updated datasets, including resolutions and coverage areas:
Population data: Hong Kong. Japan.
We regularly expand and refine our library to ensure you have the best tools at your fingertips. Keep an eye out for future updates; your planning accuracy depends on it.
Stratalignment OY has developed a live concept demonstrator using HTZ Warfare to explore the role of 5G Edge Tactical Networks in defence operations. Centred on a harbour scenario, it shows how mobile coverage, categorised by indoor, outdoor, and in-vehicle use, can be disrupted by a drone strike and rapidly restored using deployable 5G base stations.
The scenario also includes counter-UAV activation, where jamming is applied selectively to preserve friendly C2. Google Maps integration provides intuitive terrain-based visualisation, and while the current scenario is manual, HTZ Warfare’s automation tools can streamline and expand the simulation process, supporting faster, more informed tactical planning.

WSP is one of the world’s leading professional services firms, uniting engineering, advisory, and science-based expertise to shape communities to advance humanity. With over 10,000 experts in the UK and 73,000 globally, WSP pioneers solutions and delivers innovative projects across sectors: Transportation & Infrastructure, Property & Buildings, Earth & Environment, Water, Power & Energy, and Resources & Industry. Empowered by HTZ, WSP continues to deliver next-generation radio network design and assurance across major UK rail programmes.
For one key client, WSP used HTZ to model GSM-R, FRMCS, and Private 5G coverage, assess electromagnetic compatibility near sensitive sites such as the Mullard Radio Astronomy Observatory (MRAO), and evaluate the effects of design changes on radio performance.
By integrating high-resolution terrain data and multi-scenario analysis, WSP achieved greater accuracy, cost savings, and stakeholder confidence. HTZ enabled compliance validation, FRMCS migration planning, and network optimisation, delivering measurable project value across major rail programmes.
