Padus Lab: Bolstering the Energy Efficiency of the Networks of the Future

As network virtualization is rolled out, buildings that have traditionally housed telecoms equipment will also host the servers needed to run these new infrastructures. In particular, these new facilities will need to address the challenge of energy efficiency, at a time when Orange is increasingly committed to reducing its carbon footprint. The Padus Lab aims […]

A machine that lends an ear

  The embedded sound recognition models are designed to respect privacy as much as possible, shorten processing times, limit connectivity requirements and improve the energy efficiency of the system. Distributed learning is used to ensure that the service is increasingly efficient, while respecting data confidentiality. Sound source detection technology makes it possible to recognise sounds […]

When teleworking, the IoT, and AI reduce our carbon emissions

Can ecological transition and digital transformation go hand in hand? The carbon footprint of the digital sector is far from insignificant: 4 % of greenhouses gases at the beginning of 2021 and twice that by 2025 according to the ADEME, the French agency for ecological transition. However, although digital may be a burden on the habitability […]

Towards a less data and energy intensive AI

“It’s not who has the best algorithm that wins, it’s who has the most data.” This aphorism from artificial intelligence (AI) researcher Jean-Claude Heudin shows just how essential data is in machine learning. Deep learning algorithms in particular require a huge amount of annotated data (for supervised learning mode). However, data production is a long […]

Inside the data centre of tomorrow

In order to reduce a data centre’s carbon footprint, one of the first steps is to supply it with renewable energies that provide a more carbon-free source of electricity. Many internet giants, operators and hosts already power all or part of their data centres with hydro, wind, and/or solar energy. In parallel, it is necessary […]

When the Vendée Globe innovations are exported

On November 8th, 2020, the 33 competitors of the Vendée Globe set sail from the Sables d’Olonne once again to sail round the world, solo, non-stop and without assistance. This unparalleled competition may be boosted by technological innovation, but another phenomenon has also been at work over the past few years: the increasingly sophisticated technology […]

How can the environmental impact of websites be assessed and reduced?

Every website has an impact on the environment. In order to access a web page and display it in a browser, data must be carried and processed, therefore energy and CPU (Central Processing Unit) power are consumed; it is necessary to use a computer, servers and a network, whose production and use contribute to resource […]

Smart street lighting thanks to the LoRa® network

When astronomical clocks are synchronised with the LoRa® network BH Technologies, an innovative company from Grenoble partnered with Datavenue Ready and established in 1998, is one of the high-tech players in France directly involved in the Smart City movement. When it was still known as BHL Électronique, this company sold astronomical clock systems for street […]

Selective data sorting against dark data

According to a study by Veritas, 52 % of company data stored on servers is never used. This inert data is what is known as dark data. This can be data collected within the frame of an abandoned project or data that complies with regulatory compliance requirements and that has not been deleted within the legal […]

Energy efficiency: AI for mobile networks

Each generation of mobile telephony networks coincides with a leap forward in energy efficiency per bit transported, the gains of which are estimated at a factor of 10 during the transition from one generation to the other. 5G is no exception to this rule and, from the infrastructure design stage, introduces new levers for technical […]

5G : energy efficiency “by design”

The progress made by mobile networks over the years is not measured only by their operational performance and the service delivered to the end customer. They are also judged on their ability to take into account societal and environmental issues, particularly those related to energy consumption. On this subject, the progress made is substantial and […]
