Ternwaves, the nugget that enhances the capabilities of the Internet of Things

This is crazy technology that we have. We really have the potential to be unicorns. It is not for nothing that we have all left our positions, and important positions, to devote ourselves fully to this project.“, confides Julie Duclercq, the president of Ternwaves. Former director of business development for the European and Middle East markets in the automotive industry for semiconductors manufacturer NXP, the entrepreneur directed this startup created in December 2018 included Jean-Xavier Canonici and Bruno Jechoux.

Our startup developed this technology in-house until it reached an industrial level of performance and quality before starting to show it to customers.. Today, it is patented worldwide and ready to sell. We have already signed our first contract and the others will come very soon ”, continued the manager.

The trio’s work led to a software solution focused on creating a global network for the Internet of Things (IoT), thus posing as a competitor to LoRa and Sigfox technologies. Today, there will be approximately 10 billion connected objects in the world, which is far from initial manifestations, but no one doubts that their number will take on a new dimension soon.

“What is blocking the massive IoT right now, and for all the technologies offered in this market today, is their ability to deliver multiple connected objects simultaneously across their networks. Things, more collisions of messages sent and therefore missing associated objects. data and by this domino effect can lead to network collapse. We remove this lock on the number of objects connected at the same time “, announcement by Julie Duclercq.

The connectivity capabilities are 300 times greater than SpaceX’s capabilities

To develop its technology, Ternwaves approached the subject through looking for a stable modulation vis-à-vis these famous collisionslethal for data contained in sent messages.

We didgreatly increases the exploitation in the time frequency space and the results of our exceptional technology have been validated by tests in a CNRS laboratory“, confirms the president of Ternwaves. The latter even claims to be able to offer IoT connectivity capabilities”much significantly higher“among those offered by SpaceX, which uses LoRa technology with its entity Swarm Technologies. In the space segment, it is specifically working with Kineis on a radiofrequency laboratory that will be sent into orbit next fall aboard a satellite from the Toulouse nugget Loft Orbital.

Opportunities in the space sector

Able to connect to both terrestrial and satellite base stations, the Ternwaves solution also promises to go far beyond current IoT connectivity solutions in terms of sensitivity, in other words the possibility for a small object to speak in very long range. “We are working with the European Space Agency to show that we can achieve geostationary satellites in addition to those in low orbit“said Julie Duclercq. Ternwaves claims to be able to communicate with satellites in low orbit with transmission powers significantly lower than a mobile phone.

Also less energy intensive, the Toulouse technology startup could offer some particularly connected things that are capable of autonomy ”10 to 15 years oldAt the same time, the company is working with semiconductor manufacturers to optimize the battery life of these connected objects and make them energy efficient for life.

Turnover is ready to take off

Ternwaves first plans to focus on the terrestrial and space IoT connectivity markets, but also on defense. “For this last market, we have created a variant by adding a layer of cybersecurity. But our solution is largely covert because our signals are mixed with ambient noise and show better resistance to jamming.“said Julie Duclercq.

With these commercial targets, the young shoot aims for the rapid ramp-up of its activities. It expects turnover to exceed one million euros by the end of 2023.We must go far beyond these forecasts.“, assured the leader.

Beyond the fundraising that seems essential to continue to grow, Ternwaves does not close any doors for the future: either one or more partnerships with powerful industrial players, or the creation of joint ventures depending on contracts signed, which will guide the future dimension of Ternwaves.


The “10,000 startups to change the world” prize is the largest startup competition in France. It was organized by La Tribune in collaboration with BNP Paribas, the French Tech Mission, Bpifrance, Business France, the Overseas Ministry, Dalika and the National Order of Chartered Accountants.

The “10,000 startups to change the world” rewards the most promising French startups over 10 years in six categories containing the challenges of tomorrow: Environment and Energy, Industry of the future, Data and IA, Smart tech -use innovations-, Health and Start -nuggets in the seed phase. On a tour of France between January and March in 8 French cities (Lyon, Marseille, Toulouse, Bordeaux, Nantes, Paris, Strasbourg and Lille), the jury of its experts and journalists awarded 6 startups in each region, by category, ie 48 wins in the region.

These winners competed in the final on March 14 in Paris, to assign them 9 national grand prizes: one in each category, as well as a Coup de Coeur prize, an Impact prize and an International prize. . The 10th prize was also awarded to a startup from the Overseas Territories, along with three award-winning finalists in Reunion, the Caribbean zone (Guadeloupe, Martinique, French Guiana) and the Polynesia zone (Tahiti, New Caledonia). The 10 prizes were awarded on March 28, 2022 at the Grand Rex in Paris. After his success in the Toulouse regional selection, Ternwaves was the national winner in the Data and IA category.
