Network Planning Solutions for Public Safety
June 2, 2022

Network planning solutions for public safety, government and security agencies

Response times are critical when responding to emergencies and large events. Public safety agencies face growing pressure to maintain robust networks focussing on connectivity, capacity and capability.

ATDI has been supporting the critical communications industry for over three decades. Our products have adapted and evolved to meet the growing needs of industry. We support every aspect of the radio network lifecycle including design, planning and network optimisation. These networks are often used to provide temporary capacity and coverage to support recovery strategies for emergency operations.

RF Planning capabilities
HTZ Communications (HTZ) is ATDI’s flagship RF planning software. Its advanced radio network planning features support for coverage and capacity planning, the management of site parameters and neighbour planning for all the wireless technologies from a few kHz until 1 THz, including TETRA/PMR/DMR/P25, PS-LTE, GSM-R/LTE-R, UAV/UAS/Drones/Anti-drones, MW, satellites and IoT for indoor and outdoor operations. This unique software solution makes it a must-have for any public safety network operator.

HTZ supports the full radio network implementation across the entire planning stages. It provides high levels of reliability, availability and resilience for critical communication systems. It allows operators to migrate smoothly to broadband connectivity, while supporting new and emerging technologies.

Key HTZ features include:

  • Coverage & capacity planning
  • Interference calculations
  • Prospective planning with automatic site searching and route planning
  • Automated handover, neighbour list planning and analysis
  • Monte Carlo simulations
  • Delay spread and simulcast performance analysis (P25)
  • Automatic site planning and optimisation
  • Automatic frequency planning
  • Traffic & mobility profile editor (for end devices).

HTZ features unparalleled capabilities for modelling and simulating radio systems. It features fully deterministic propagation models, including the advanced “Deygout 94”. This diffraction model guarantees fast and accurate coverage predictions, providing a high correlation percentage between predictions and measurements compared to other RF planning tools. 

Cartographic data

To support successful network planning, ATDI supplies full cartographic datasets for every corner of the globe. Planners can choose from medium-resolution and high-resolution datasets or a hybrid of the two. The ATDI library includes LiDAR data, which provides data sets sub-1m resolution which benefit from surface and terrain elevation points. ATDI currently offers high-resolution map data with a 3D building layer for 70% of North America.

Drones
With a growing need to protect no-fly zones, drones are now deployed to safeguard areas like airports, critical infrastructure and large public spaces. Counter-drones can be managed in HTZ to jam the signal between the unauthorised drone and the drone pilot.

HTZ Communications offers dedicated features for drone management, enabling operators to:

  • Plan flight missions and optimise a mission path to avoid interference or jamming
  • Share the flight path information with a drone-controller localization feature. This identifies areas where the controller can potentially share information.
  • Identify areas where jamming can be effective to manage unauthorised drone users in no-fly zones around airports and other security sensitive sites
  • Analyse the drone communication range by importing and analysing flight paths for RF simulation
  • Analyse the reception at different flight heights in a 3D environment for different elevations.

Satellites
The adoption of satellite broadband services for the public safety market is growing. Satellite provides improved connection speeds and bandwidth not just for rural and remote areas and emergencies, but to meet the unprecedented demand for data. HTZ enables network operators to plan and model the satellite footprint for coverage, as well as analyse link budgets to guarantee capacity. It identifies and manages constellation interference, as well as evaluating interference between the satellites and earth stations.  Its advanced satellite network planning functions for GSO/non-GSO satellite operators, include:

  • GSO/non-GSO satellite coverage planning and link budgets
  • Wide-beam and HTS-beam planning across all satellite frequency bands
  • Connection and import of ITU SRS database and TLE files
  • Automated site planning, optimisation, and frequency planning
  • GSO vs GSO and GSO vs non-GSO interference analysis
  • Satellite vs terrestrial co-existence analysis
  • Earth station coordination
  • DTH network planning
  • VSAT network planning and optimization

HTZ covers all satellite services including FSS, BSS, MSS, Earth-exploration and meteorological.

Network Automation
Emerging technologies like LTE and 5G have driven the uptake of data-reliant services. To ensure networks are robust and resilient, HTZ builds networks that self-heal.  This means that every network node can intelligently sense and discover other nearby nodes, and dynamically determine the optimal path for forwarding data packets through the network to another node. This results in improved performance, network reliability and reduced disruption.

Using automation features in HTZ, transmission paths can be planned over different terrain and environmental conditions, and when nodes break down or lose connectivity paths can be re-routed.

These highly functioning self-healing networks provide end-to-end connectivity, which far exceed that of traditional point-to-point networks.

HTZ Publisher
This cloud-based solution shares coverage outputs flexibly and securely. HTZ Publisher is compatible with HTZ, publishing coverage calculations for internal and external users on high-resolution maps.

The browser-based app can be accessed on a PC, tablet or phone and features automated workflows to simplify user interactions. The intuitive user interface requires no training and pre-rendered maps remove overhead delays allowing large data sets to be published quickly and easily.

HTZ Publisher is well suited to Control Centres who need to provide network coverage reports to support operations. The tool can turn stations on and off to simulate their impact on network coverage which is particularly useful during an emergency when stations maybe lost. It also supports regular network maintenance, allowing the network operation centres to switch off stations during the field operations without the risk of significantly impacting the overall network coverage.

HTZ Publisher supports external stakeholders by providing access to real-time network coverage reports. These can be made available via a public web service or as a bolt-on service for various emergency service users accessing the network.

Webinars
Our next event looks at how 4G/5G and non-terrestrial networks (NTNs) can support innovative new applications using spaceborne or airborne assets to provide connectivity in areas previously with no coverage or during an emergency. The webinar will include an overview of the challenges facing LEO satellites and how coverage can be achieved to support data-driven applications. We will look at two use cases which have application in the critical communications sector including:

  • Operating drones in a swarm using ground and satellite gNB. This will focus on beamforming antennas to combat jamming threats, inter-connections between drones and 5G stations and mission preparations, and
  • Simulating communications to support autonomous vehicles. This will focus on managing remote sensing, real-time positioning and the management of unmanned vehicles and other autonomous hardware in the field.
