ATDI announces an innovative method to build digital terrain dedicated to propagation of electromagnetic waves.

How to improve the quality of radio planning:

Actual medium resolution clutter data dedicated to radio planning are based on classification (Dense urban, Suburban, Village, Building blocks, forest, hydro…). With this type of datasets, deterministic propagation models give acceptable results compared to measurements, however, a lot of measurement points cannot be correlated (even with tuning), due to the lack of accurate digital terrain and clutter information (heights and locations of the obstacles, open areas…).

This is why we have developed an innovative method to build more accurate DTM and clutter layers that can be used to create Medium Resolution (10m-20m) and High Resolution datasets (1m-5m).

Different free and commercial sources are combined to create more accurate layers at reduced costs compared to standard datasets.

 

In our example below, on a Medium Resolution dataset (20m)we extracted uncorrelated points from mobile measurement survey, then we performed fixed measurements on these points and built an innovative DTM/Clutter/Building dataset from open data to get better measures/predictions correlation results.

We have used Deygout 1994 / Fine-E propagation model in ICS telecom EV.

Dataset resolution: 20 m.

Test transmitter: 50 W / 138 MHz.

 

Standard Clutter (landcover) model (urban and vegetation contours):

New clutter layer built from Clutter/Building extraction model (Dataset made with ICS telecom EV and ICS map server):

Above, we can see a more realistic urban repartition (in red) than Standard Clutter model.

Building elevations are extracted and medium and high vegetation areas are classified.

Linear (roads, railways, waterways) are added to delineate urban blocks.

Processing time:

< 2 minutes (22 000 km²)

 

Coverage calculation result comparison

Above: Coverage calculation performed on New Clutter model. We can see a more realistic impact of urban blocks (West), and vegetation (East)

 

Correlation results (originally uncorrelated points only @20 m):

Clutter method Standard deviation Average error Correlation factor
Standard classification 6.78 dB -1.54 dB 0.72
Building extraction 3.81 dB 1.62 dB 0.92
Building extraction + Linear 3.79 dB 1.73 dB 0.92
Buildings transformed to 5 Clutter classes 3.83 dB 1.73 dB 0.92

 

This new method improves significantly the quality of simulations, especially in urban areas. It’s free for Medium resolution datasets and at very affordable price for High Resolution datasets.

We, at ATDI, continue to improve this method. Objectives:

  • Reduce radio planning costs
  • Get always more accurate results
  • Produce data faster

 

Cost:

Resolution Price in Euro
2 m 150 €/km²
5 m 40 €/km²
10 m 5 €/km²
Medium Resolution 0 €/km²

ATDI joins NATO Communication and Information Agency  Basic Ordering Agreement, an IT solutions and services supplier who support NATO operations and missions.

This successful application allows ATDI to sell its state-of-the-art solutions and services in spectrum management and communications electronic warfare to NATO members.

Membership of the NCIA BOA reflects ATDI’s commitment to meeting challenging operational requirements in the field of spectrum dominance for the Alliance and its members. Given ATDI’s lead in spectrum dominance they are also engaged in the discussions of the Spectrum Tools Configuration Control Team of the NATO Consultation, Command and Control Staff, regarding spectrum data exchanges between NATO nations and the NATO command structure.

SSE has extended its relationship with utility businesses through the purchase by SSE (Scottish and Southern Energy) of an enhanced and expanded suite of radio planning and modelling software.

Two arms of SSE now use ATDI’s flagship radio planning tool. One of them, Scottish and Southern Electricity Networks (SSEN), provides real-time system delivery for SSE through its SCADA network. This includes RF and propagation modelling, as part of overseeing the company’s control systems across the UK. The other division is SSE Enterprise which works with SSE’s renewables, network and generation operations. The latest purchase will be used by SSE’s telecoms network design team to carry out detailed surveys for near line-of-sight radio connectivity to substations, wind farms and other company infrastructure. The radio links enable SSE to manage its electricity distribution network.

SSE’s extended relationship with ATDI adds to ATDI’s existing customers in the utilities industry: Western Power, sector radio regulator JRC, and ESB in the Republic of Ireland.

ATDI lead engineer Simon Parsons, who was a manager at JRC for 20 years, comments: “It is gratifying that this vital industry relies on ATDI to this degree. There are now a number of UK energy utilities using ATDI tools and one of the attractions to those companies is that ATDI software delivers a consistency of output for all of them. The ability to share spectrum management data seamlessly with JRC is the most efficient way to manage spectrum resources.”
