Start-up company Energysquare has created a wireless charging device for tablets and cellphones. Using a simple mechanism combining a sticker and a metal plate, devices can be charged by conduction. Energysquare, which is incubated at Télécom ParisTech, will soon see its technology tested in hotels. The company now also aims to export and adapt its product to other smart objects. …

With the phenomenal growth connected objects are experiencing, networks to support them have become a crucial underlying issue. Networks called “LPWAN” provide long-range communication and energy efficiency, making them perfectly suited to the Internet of Things, and are set to become standards. But first, they must be successfully integrated within traditional internet networks. This is precisely the mission of the …

Hervé Debar, Télécom SudParis – Institut Mines-Télécom WannaCry was the first case of a cyberattack that had a major effect on hospitals. The increasing digitization of hospitals (like all areas of society) offers significant opportunities for reducing the cost of health care while making the care provided more effective. However, with digitization comes cybersecurity challenges and these threats must be …

For four years now, researchers from EURECOM and the startup Data-Moove have worked together to radically improve the tourist experience in various regions. With help from technological innovations from laboratories, they have succeeded in aggregating the information available on the web and social networks to create a local and comprehensive picture of what a geographical area has to offer.   …

Hervé Debar, Télécom SudParis – Institut Mines-Télécom, Université Paris-Saclay “Athird of the internet is under attack. Millions of network addresses were subjected to distributed denial-of-service (DDoS) attacks over two-year period,” reports Warren Froelich on the UC San Diego News Center website. A DDoS is a type of denial-of-service (DoS) attack in which the attacker carries out an attack using many …

5G will inevitably involve opening new frequency bands allowing operators to increase their data flows. Millimeter waves are among the favorites, as they have many advantages: large bandwidth, adequate range, and small antennas. Whether or not they are opened will depend on whether they live up to expectations. The European project H2020 TWEETHER is trying to demonstrate precisely this point. …

New uses for 5G imply a new way of managing telecommunications networks. To open the way for new actors, we will have to divide and virtualize network slices, and find a dynamic way of allocating them to new services. This organization is made possible thanks to SDN: a technique which redesigns network architecture to make it as flexible as possible. …

The storage of green energy is an issue which concerns many sectors, whether for energy transition or for supplying power to connected objects using batteries. Thierry Djenizian, a researcher at Mines Saint-Étienne, explains the main problems to us, focusing in particular on how electrochemical storage systems work.   Why is the storage of renewable sources of energy (RSE) important today? …

At the IMT “Energy in the Digital Revolution” conference held on April 28, Bruno Lacarrière, an energetics researcher with IMT Atlantique, presented modeling approaches for improving the management of heating networks. Combined with digital technology, these approaches support heating distribution networks in the transition towards smart management solutions. The building sector accounts for 40% of European energy consumption. As a …

It is now widely accepted that algorithms can have a transformative effect on a particular sector. In the field of telecommunications, they may indeed greatly impact how energy is produced and consumed. Between reducing the energy consumption of network facilities and making better use of renewable energy, operators have embarked on a number of large-scale projects. And each time, algorithms …
