HTZ Communications offers advanced radio network planning and optimisation capabilities for almost every technology from a few kHz to 1 THz. This integrated solution manages the entire radio planning lifecycle.

For over three decades, it has been the choice of spectrum regulators, critical communications and telecom operators, providing an unmatched degree of precision and quality for users.

HTZ  features a comprehensive propagation engine which supports the design of outdoor, indoor, and outdoor-indoor networks. It supports a library of over 50 empirical, deterministic and hybrid propagation models, including all ITU-R models, Okumura-Hata, Cost-Hata, Irregular Terrain Model-Longley Rice, ITU and 3GPP models.

HTZ Communications replaces ICS Telecom. ATDI offers an upgrade to any perpetual license users of ICS telecom to the latest version of HTZ communications.

What are the sources for ATDI map data?

Reliable map data is essential to support radio network planning. ATDI offers high-quality royalty-free digital maps to customers with a valid maintenance contract. This data is sourced from various resources, including LiDAR data, Corine land cover, and Open Street Map, …

Can I use my customised propagation model in HTZ?

HTZ allows users to integrate their custom propagation models into the software. For more information, please contact

Can I model indoor propagation with HTZ?

Our software supports the complete network lifecycle including network design, planning and optimization. It allows engineers to model coverage from outdoor into indoor spaces and indoor to indoor, providing seamless coverage for end users.

Do you offer academic or research licenses?

ATDI offers Universities access to HTZ Communications licenses at a competitive price. Licenses can be hired for the academic year according to the numbers required. For the price of the packs available, please contact your local office.

U-Pack 5: for 5 simultaneous users

U-Pack 10: for 10 simultaneous users

U-Pack 25: for 25 simultaneous users

The educational packs include access to a dedicated server license, which allows a maximum of simultaneous users depending on the pack purchased.

HTZ Warfare licenses are available for military research agencies and training schools for students wishing to complete their thesis, providing this thesis offers contributes to developing a subject or theory for the telecom market.

What's the difference between ICS telecom and HTZ?

Contributing over three decades of research and development to our software solutions, we can't be accused of standing still. Over 90% of our customers have now migrated to HTZ and are reaping the benefits from the improved user interface and user experience. Most importantly, the biggest advantage is the reassurance and support they get from their maintenance contract. This allows users to access all the latest HTZ releases including beta versions, get help from the technical support desk and access our comprehensive map data library. Contact your local office to discuss your upgrade today.

Can I still use my old dongle?

As part of the upgrade from ICST to HTZ, we now use soft key activation codes. These are installed in the software directory for standalone licenses or on the server. The license options for these are listed below:

Standalone licence/s: This licence is attached to one standalone PC or laptop. Once the licence has been activated, it remains attached to the computer where the activation is initiated. No other application or software tool is required for set-up. A standalone licence allows each user to operate up to three instances of the software (CALs) at any one time.

Server licence: A Licence Server Management Tool needs installing and the server licence must be activated on that Server. The Client computer will then connect to the server to activate their local license. Any computer connected to the LAN can use HTZ, with the number of concurrent users or sessions equal to the number of licences available. A server licence allows each user to activate one instance of the software (CAL) per licence at any one time.

What propagation models are available in HTZ?

Our software supports a plethora of propagation models. For the latest released version, contact our support helpdesk.

What choices do you offer for hosting your software?

ATDI offers a choice of software hosting options. Our users adopt a desktop solution (standalone) or through LAN-server license or VPN (server) or via the end-user Virtual Machine (VM) or cloud-based server options (cloud).

We’ve simplified our product version numbers for HTZ: version xxxx.yy.z with xxxx = year and y or yy = month. z denotes when more than one release is made in the same month. For example, 2024.1 was released this month and 2024.1.1 = second release in the same month.
