HTZ : the first commercial software dedicated to wireless radio network planning was created in 1988 in Paris, as an answer to a challenge proposed by the Technical Director of M6, Marc Roussel. However, the purchase of the product was not planned and it was necessary to find a buyer.

Once the benefits of the software were acknowledged, it was easy to find the distributors – two French companies. Software benefits even gave one of the distributors the idea to sell without authorization the HTZ source code to two another companies: German and Spanish.

Energy of the source
Tensions with distributors gave an idea to the software creator to establish its own company. ATDI was launched in April 1991 in Paris. Company is developing software solutions HTZ (radio planning, technical spectrum management, communication electronic warfare) and ICS (radio planning, spectrum management, digital cartography). The co-authors of ICS join ATDI between 1992 and 1993.

Power of the signal
Being in constant development allows ATDI to create rapidly its innovative and even futuristic vision. In 1991 ATDI participates together with Thomson-CSF in the concept creation and realization of the first Radio Frequency Spectrum Management and Control System. In 1992 ATDI participates in the development of the first French drone system created for STAT. At the end of 1994, in collaboration with Jacques Deygout, ATDI integrates in HTZ new version of the diffraction model which gives unrivaled precision to the calculations, no matter what is the quality of DTM, frequencies used (V/U/SHF), number of obstacles or the eclipse of the Fresnel ellipsoid. Those concepts would have to wait until CRC-Predict and the ITU-R 1812-2 model (2012) to be found.
In 1997, the Monte-Carlo module of ICS telecom offers a variety of more than 30 parameters. It will be used for the prospective analysis of compatibility of Teledesic and Skybridge systems.

ICS telecom is also the first software to integrate the following innovative functions :

  • Automatic network planning from « subscribers » database (1999)

  • Direct interface with the systems of preparation and restitution for the low altitude flights mission (2002)

  • Integration of the radio planning software for the deployment of HF systems on Mars – NASA (2004)

  • « On The Move » concept (connections, jammers, interferences in real time between the mobile devices and protection of convoy – MoD USA (2007)

  • Online radio planning with Spectrum-E (2011)

  • Implementation via « Cloud » of digital maps (2012) and network and equipment data bases (2013)

  • Automated planning of AMR and GSM-R networks (2013)

Speed of propagation
Originally focused mainly on the broadcast (with Thomson-LGT, CLT), PMR and radiotelephony (Matra, Sofrecom), activity of ATDI was extended to electronic warfare and tactical communications (Thomson-CSF, ERGE), spectrum management (Tadiran, Bakom) and microwave networks (Marine nationale française). Today, ATDI offers its software solutions to all sectors of radio communications both civilian and military (CEW, UAV, SAT, LTE, UMTS, TETRA, DMR, MW, PAGING, AMR, MLAT, DME, ILS, VOR, FM, TVA, TVD, DAB, PMRA, BWA, WIFI, WIMAX, GSM, GSM-R, HF…).

In 1996, taking advantage of the discussions about acquiring of Thomson-CSF by Lagardère group, ATDI buys SM/EW division of Thomson-MEL in Crawley (UK). This will become ATDI’s first foreign office. Afterwards ATDI opens offices in USA, Spain, Russia, Australia, Ukraine, Poland, India and Singapore.
In 2012, ATDI chooses a new form of products and services distribution – implementation of direct and indirect network of sales in Europe, Asia and Africa by agents, distributors and Certified Partners.

Signal of reception
Today ATDI counts 2013 companies among its customers since the creation of the company and more than 18 new versions of ATDI software solutions has been released all over the world since that time. ATDI stays among the leaders of the world market of all-in-one solutions for radio network planning and spectrum management and is an undisputed leader in electronic warfare and tactical communications field.
