ATDI has over three decades of operating in the radiocommunications industry. During that time, our software solutions have developed and continue to evolve. These comprehensive software solutions allow users to manage any radio technology. They even allow users to model multiple radio technologies across one project.
Railway networks connect communities and support economic growth. But these complex networks require advanced solutions to ensure they meet the growing demand for services. ATDI provides cost-effective and sustainable telecom network solutions to meet those demands.
Railway operators rely on different technologies to support rail operations.
Today’s railways present a new set of challenges for telecom networks including international border-crossing interoperability and increased rail track capacity.
GSM-R and other radio technologies are essential to the efficient running of railway operations. They offer a variety of voice and data communications services and manage a large number of radio frequencies used by different radio applications, systems and users. Using a spectrum management solution ensures adequate spectrum is available for network coverage and capacity, without causing undue interference to other radio users.
With the increase in spectrum scarcity, the rail industry continues to look for new and innovative approaches to spectrum management. Initiatives like spectrum sharing, hardware improvements (receivers), using frequencies in higher bandwidths and the use of more spectrum-efficient technologies are now being witnessed.
In addition, railway network operators have seen an increase in demands for services such as:

5G networks offer increased capacity, lower latency and faster speeds. They can operate in the higher frequency bands between 28GHz and 60GHz. This range is known as the millimetre wave (mmWave) spectrum. In addition to greater bandwidth, 5G networks have a dense, distributed network of base stations or small cells. 5G networks offer ultra-reliable, low latency as a result of increased processing, which supports emerging trends like mobile gaming, industry robotics, automated vehicles and technology advances in healthcare.
Small cells in 5G networks support the increased data capacity and can reduce network rollout costs by eliminating expensive rooftop installations. 5G networks need built-in flexibility to coexist with other standards like LTE & Wi-Fi and, where feasible, to support spectrum sharing.
Signal loss can be modelled in a real-world environment using high-resolution mapping, which characterises the geo-spatial environment and identifies features that will impact mmWave propagation.
The key functions require a radio planning solution that includes:

Air travel is predicted to grow over the coming decades. Airports use an abundance of wireless technologies to connect passengers, devices, safety-critical systems, and aircraft.
Operationally, airports use three types of communication systems: ground communications for controlling operations, ground to air communications for managing airspace and radars for monitoring enroute operations.
Ground communications frequently rely on emerging technologies like LTE and 5G which feature increased data rates. But airports continue to use other radio technologies like VHF/UHF, Wi-Fi, telemetry, and TETRA. These networks must work seamlessly to ensure the airport operates safely and securely.
Equally, air traffic controllers need to ensure that ground-to-ground communications are compatible with their ground-to-air services and do not interfere with other service users. Ground to air communications use a variety of technologies including radar, UHF/VHF and HF. Common functions of ATC radars include enroute radar systems, air surveillance, surface movement and weather radars. ATDI supports leading ATC operators around the world.
HTZ offers dedicated functions for the aviation sector including:

As the use of drones or unmanned aircraft (UAV) grow, businesses and Governments are seeing significant demand and growth in areas like transport, military, logistics and commercial sectors.
Drones are controlled by a ground control system (GSC) which operates remotely or autonomously. Wireless connectivity lets pilots view the drone and its surroundings from a birds-eye perspective. Users can also leverage apps to pre-program specific GPS coordinates and create an automated flight path for the drone.
The data links use a radio-frequency (RF) transmission to transmit and receive information to and from the UAV. These transmissions share information like location, distance and location to target, distance to the pilot, payload information, airspeed, altitude and more. An autonomous drone can conduct a safe flight without the intervention of a pilot.
HTZ Communications offers dedicated features for drone management including:
In the defence and security sector, UAVs are used as target decoys, for combat missions, research and development. Their growing use has reduced losses in the field and enables the execution of high profile and time-sensitive missions.
Anti-drone systems are used to detect or intercept unwanted unmanned aerial vehicles. More often, anti-drone technology is deployed to protect areas like airports, critical infrastructure, large public spaces and military installations and battlefield sites.
Counter-drones are used to jam the signal between the drone and drone pilot.

Often technology advancements and deep pockets win wars. However, good communication networks in the battlespace can be the difference between military success or failure. Nowadays, ministries of defence are compelled to assess their radio spectrum use to ensure their spectrum management practices reap maximum benefits.
Defence & security communications have been an integral part of ATDI since its outset. The scope of this work ranges from auditing the use of military spectrum to advising and supporting studies on coexistence, releasing spectrum for commercial use and the reallocation of spectrum for reuse with other technologies.
HTZ Warfare offers dedicated features for the defence and security markets including:

For over a decade radio broadcast has been responsible for distributing and publishing news. During that time, we’ve seen the introduction of new technologies and the transition from analogue to digital broadcast. It wasn’t till the 1950s that television broadcasting made an entrance. During that time, broadcasters have adapted to viewing trends by focussing on emerging technologies to drive the sector. While the broadcasting environment has changed with the introduction of the internet, traditional broadcasters still retain a large market share of viewers and listeners.
ATDI has a long affiliation with many of the World’s leading broadcasters. Our flagship tool, HTZ Communications enables broadcast network operators to serve a maximum number of users at a minimum cost. We have supplied software and services to assist with key areas such as network planning and modelling for every broadcast technology. During the project life cycle, we help dimension the network using correlation analysis and propagation optimisation.
HTZ Communications was integral to broadcasters when migrating from analogue to digital radio (DVB-T and DAB+), and supports network maintenance and subsequent upgrades to DVB-T. With a wealth of functions featured, ATDI guarantees efficiency and cost-effectiveness at all stages of the network lifecycle ranging from:
The technologies covered by HTZ include:

Electromagnetic Spectrum (EMS) is widely used for military operations. Competing demands for radio spectrum means it must be strictly coordinated and controlled. Battlespace spectrum management is the planning, coordination and management of EMS, to enable military systems to perform their functions without causing or suffering from harmful interference.
Significant importance is placed on the performance of radio intercept receivers, direction finders and communications jamming equipment. Key features that determine the success of a mission is the ability to intercept or jam enemy communications. And similarly, to share information with the command structure without undue interference.
With over three decades of development, HTZ Warfare is a leading military network planning and EW modelling tool. This feature-specific software supports military units around the World. Key functions include:

Technology is an integral part of our lives, along with our growing dependency on it. The Internet of Things (IoT) covers everything connected to the internet. The overarching feature of IOT is the wireless data transfer and its application supports smart home devices, eHealth applications or driver-less trucks. With connectivity driving technology innovations, the design and roll-out of wireless networks has to be managed effectively.
HTZ supports every aspects of IOT radio network planning, including coverage and capacity planning and interference analysis. Other key functions include:
From a planning perspective, IoT networks differ from classic radiocommunication networks. To support this, HTZ offers interactive 3D city models and urban information for high-resolution network planning. It supports a variety of IoT application platforms and other cloud-based solutions. The software features accurate propagation models specific for IoT including LPWAN, IEEE 802.15.4, 3GPP.
HTZ features dedicated functions including:

The mining industry is rapidly modernising with smart mining operations projected to increase threefold by 2025. Automation plays a key function in this transformation and has the potential to increase productivity and improve safety and working conditions. For example, transportation in mines is a repetitive task that is well suited to autonomous vehicles which operate around the clock. Private cellular networks connect those vehicles to coordinate paths and exchange mission-critical information.
Due to constant changing environment in the mine, the transmitters and receivers move which can cause reflections, scattering and other diffraction phenomena. Modelling the impact of these changes on network coverage needs to be managed regularly, otherwise, operators run the risk of communication failures.
ATDI works with many of the world’s largest mine operators providing network planning and modelling expertise in the form of software solutions, consultancy services and custom training. These solutions reduce the risk associated with the changing terrain and allow operators to automate their coverage plans frequently. ATDI’s flagship radio planning software, HTZ Communications features key functions that are well suited to managing the issues facing open-mine operators.
Prospective planning: Understanding the impact of terrain changes is essential to network planning. HTZ Communications features a prospective planning function to allow operators to model these challenges over time. These plans can include the best location for fixed transmitters and coverage achieved. Operators can manage their activities more efficiently and remove the risk of communication failures. Identifying communication not-spots allows operators to use gap fillers or trailers to fill areas without coverage.
Automation: Mine operators use scanners or sensors to monitor terrain changes within the mine. Using HTZ Communications, operators can import the updated maps into the software which triggers their conversion into ATDI’s format. Once imported, the software automatically calculates coverage and produces a composite coverage based on the terrain changes. Functions like identifying the best servers, composite coverage and coverage overlapping are also supported.
In addition, SINR throughputs for LTE and 5G networks can also be automated. The results from these calculations are exported in KMZ and TIF/TFW files and are published via a display engine in the Operation Centre. By automating workflows, users can make time and resource efficiencies and reduce the risk of errors in repetitive manual processes.
Accuracy: ATDI’s propagation engine defies laws of physics. The tool has proven to deliver highly accurate predictions, outperforming other planning tools that have evolved from the classic mobile telco needs in urban and suburban environments. ATDI’s propagation engine is well suited to open-cut mines and deep pits. The latest measurements in open-cut mines show a correlation exceeding 95% with less than 1.5 dB margin of error.

Safety at sea depends on good communications between ships and from ship to shore. But radio waves traversing water behave differently to those moving above dry land. This means a new set of variables must be modelled to achieve reliable maritime communication networks. Considerable research has been undertaken into propagation modelling in a maritime environment.
HTZ is used for maritime transport critical communications, as well as cross-border surveillance and emergency response communications. Key features include:

Offshore gas and oil operators use mobile technologies like LTE for monitoring components on rigs and communications with the shore. Establishing and maintaining communication links in the face of extreme weather conditions can be a challenge. Commonly, satellite or fibre optic links are used, but more often mobile technologies are replacing rig to shore communication links.
In an environment where safety is critical, any restrictions with bandwidth, or delays often characteristic with satellite services, are not viable. LTE enable rigs, shore bases and support vessels to share information in real-time. Similarly, demands for data on the platforms is growing, with the need for indoor coverage like WiFi and a robust network to manage monitoring and telemetry systems.
HTZ Communications offers dedicated features to manage offshore communications, including:
Response times are critical when managing emergencies, disasters or crises. Both government and public safety agencies face growing pressure to improve event management with the spotlight on connectivity, capacity and capability. Access to mobile broadband is the key to effecting this change.
Public safety networks have three main roles, to support real-time situational awareness and intelligence-driven solutions:
Traditionally, public safety networks used TETRA, TETRAPOL and Project 25. The introduction of 4G (LTE) and specifically PS-LTE, has driven the uptake of data-reliant services. Aside from national public safety networks, there has been significant growth in private LTE networks, providing temporary coverage for pop-up test centres and field hospitals in the fight against COVID-19.
These secure and resilient mission-critical networks must guarantee connectivity for everyone, anywhere and anytime. ATDI has been supporting public safety network operators for over three decades. The key functions of HTZ Communications include:
HTZ features a traffic and mobility profile editor to limit access for low-priority users to free up resources for higher priority users during an emergency. Its propagation models perform coverage calculations to a high level of accuracy without the use of the automatic model tuning module. And, the automatic model tuning module, which can be used at the calibration stage to improve the final AFP result, can be used when drive test measurements are available.
Satellites provide vital communications to any part of the World. However, the technology is associated with problems that can be mitigated through network planning and modelling techniques.
Propagation delays from one VSAT to another can exceed 0.5 seconds, that can impair voice communications resulting in echo and talker overlap. These delays can be resolved by applying special protocols. Satellites are also susceptible to the effects of rain and atmospheric disturbances, commonly known as noise. To support this, ATDI’s software features rain maps and other significant atmospheric data to support network planning.
HTZ is a comprehensive radio network planning tool that enables network operators to plan and model the satellite footprint. It also models and manages constellation interference and evaluates interference between the satellite and earth stations.
HTZ features advanced satellite network planning functions for GSO/non-GSO satellite operators, including:
Radio spectrum is the lifeblood of the radiocommunications industry. It’s the allotted frequencies or spectrum which supports all wireless communications. Spectrum regulation, also known as spectrum management, is the regulation of those frequencies to promote its efficient use and to maximise the net social benefit. Radio spectrum typically refers to the range of frequencies from 3 kHz to 300 GHz.
ATDI has been at the forefront of developing automated spectrum management solutions for national and regional spectrum regulators for over three decades.
Their solutions allow regulators to:
Key features include:
Integral to spectrum management is the ability to monitor spectrum use to ensure frequencies don’t interfere with each other. Radio spectrum licenses are allocated by band or technology with spectrum monitoring tools scanning the bands to ensure users have access to the spectrum without interruption or undue interference.
For spectrum regulators, a monitoring system needs to gather both spectrum management and spectrum monitoring data. The monitoring system needs to create reports about license conditions and relevant monitoring data. These reports allow the regulator to monitor spectrum use and trends, in real time. Regulators use this information to manage complaints and ensure compliance.
For other wireless network operators, measurement campaigns use a spectrum analyzer. The spectrum analyzer captures measurements from the network in real-time and allows network operators to validate network performance indicators (KPIs).
HTZ is compatible with leading equipment suppliers and is used to:
The HTZ user interfaces easily imports large amounts of data for processing.
A mesh network is a local network topology where the infrastructure nodes connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate to efficiently route data from/to clients. The lack of dependency on one node allows every node to take part in relaying information. This makes mesh networks extremely resilient, as they constantly look for new paths, rerouting links to ensure that any network failure is resolved without impacting the overall network efficiency. Mesh networks are highly scalable, allowing for both traffic and area covered to change in response to network growth.
As the result of a single point of access, mesh networks benefit from better coverage and minimal dead zones or not-spots. Network set up is easy to configure as nodes automatically reconfigure connections. The downside to mesh networks is the slower speeds achievable as every ‘hop’ can increase delays.
Radio planning mesh networks can be divided into three main tasks: dimensioning the mesh node distribution to achieve the required coverage; analysing the links of the mesh nodes to optimise the dynamic routing and ensure demand throughput; backhauling the gateways (microwave links).
Successful network planning relies on the cartography used. Planners need to decide whether to use medium-resolution and high-resolution datasets or a hybrid of the two. Costs need to be balanced against the overall value of the different map resolutions and planners must make choices about how they impact the project.
ATDI has a library of map data from around the globe, which is available to all customers with a valid maintenance contract. This includes LiDAR data, which provides data sets sub-1m resolution and benefits from both surface and terrain elevation points. These high-resolution datasets provide precise modelling with sharp blockages.
The days of a man with a torch peering into your understairs cupboard to read your electricity meter have gone the same way as faxes and video cassettes. With utility networks moving towards smart metering, consumers are benefitting from cost efficiencies and accurate billing. Mitigating interference in smart networks is a challenge, particularly as broadcasting frequencies become more crowded. And achieving maximum coverage at the lowest possible cost is essential in today’s financial climate.
ATDI has been supporting utility companies and their communications infrastructure for their transmission networks for the past three decades. The main technologies used by utilities include:
HTZ Communications offers dedicated features to utility companies including:

While the growth of onshore windfarms may have slowed, offshore developments are rising – and each one has the potential to interfere with radar systems used by air traffic controllers. National civil aviation authorities are responsible for the safe transit of aircraft through their airspace and require all wind farm developers to determine whether their turbines’ will impact radio communications before they are built.
Wind farm developers need to manage the impact of turbines on civil and military aviation infrastructure. This includes evaluating the impact on radars and surrounding telecommunication services. With accurate planning and modelling, the impact on air traffic control systems in the proximity of a wind farm can be mitigated.
HTZ Communications offers dedicated features for windfarm mitigation studies including:
