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 Standard Clutter model

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 is now building a new China dataset. Will be available soon: www.atdi.com/cartography

Communiqué de presse

 

RADIOCOMMUNICATION : L’Agence Nationale des Fréquences confirme son choix de continuer à travailler avec ATDI

 

Le groupe ATDI se félicite que l’ANFR, l’Agence Nationale des Fréquences, (chargée par l’Etat des missions de planification, de gestion de l’implantation des émetteurs, de contrôle et de délivrance des autorisations et certificats radio) ait renouvelé le 13 juillet 2017 la maintenance et les supports des licences des logiciels d’ATDI.

 

L’Agence Nationale des Fréquences a confirmé son choix de continuer à utiliser les logiciels de calcul et d’ingénierie conçus par les équipes d’ATDI permettant toute la gestion du spectre électromagnétique en France : renouvellement de 36 licences du logiciel ICS telecom et package pour un nombre illimité de licences du logiciel ICS Manager.

 

Ces dernières années ont été marquées par une croissance spectaculaire des usages en matière de radiocommunication et la gestion du spectre hertzien (l’ensemble des fréquences sur lesquelles peuvent opérer tous les systèmes de radiocommunication) est un enjeu majeur pour l’Etat.
Depuis plus de 20 ans, ATDI demeure un partenaire historique des autorités françaises pour aider à la régulation de ce secteur sensible, tant dans le domaine civil que militaire.

 

A propos d’ATDI : Créée en France il y a près de 30 ans, ATDI (Advanced Topographic Development et Images), désormais groupe international, conçoit, développe et publie des logiciels spécialement conçus pour répondre aux exigences de la radiocommunication et de la guerre électronique, la gestion du spectre, la surveillance, la cartographie numérique, la conception et l’optimisation des réseaux.

ATDI est le leader sur le marché mondial en termes de planification et de modélisation des réseaux radio, de gestion du spectre, de spectre dynamique et d’optimisation des réseaux.
Le groupe ATDI soutient actuellement 2000 clients dans le monde, dont plus de 90 autorités nationales de régulation du spectre.

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.
