Developing an embedded electronic solution in a matter of weeks rather than years: that's the challenge taken up by Renardo, a young start-up incubated at IMT Atlantique. Born out of the industrial and educational experience of its two founders, the start-up offers a modular ecosystem combining hardware and software. The aim is to increase responsiveness and democratize electronic innovation, while meeting industry requirements.

In a context of constantly growing needs for data transmission, 5G and 6G networks must comply with increasingly strict technical obligations in terms of flexibility, miniaturization, and energy optimization. Solutions explored by researchers include optimal management of radiation patterns and the development of concrete applications for millimeter wave frequencies. Two projects, YACARI and PIIEC ME/CT, are tackling the technical obstacles to these approaches by combining different antenna technologies.

Faced with the expansion of 5G and the challenges of 6G, energy restraint and exposure to electromagnetic fields are becoming major issues for the networks of tomorrow. Between optimizing infrastructures, mobile sensors and prediction models, scientists are striving to reconcile performance, lower consumption and quality of service. Just Enough Network, a project co-led by Télécom Paris, is therefore trying to build networks that are ‘just enough’ to meet our needs, without surplus or wastage.
