Leti’s telecommunications projects leverage our competencies in micro- and nanotechnologies, component design, and system design to support innovation in the development of wireless communications. These projects help us to anticipate future needs in telecommunications.
We are focused on the lower layers and protocols of telecommunications systems and optimizing their use: antenna systems, RF front-ends, digital baseband, sophisticated signal-processing algorithms, medium-access control protocols and radio resource-management techniques.
Partnering with global leaders
Recent projects include a new radio technology for high-speed and short-range wireless data transfer with Nokia, sensor networks for Fujitsu and cellular equipment.
We also collaborate with, among others, Alcatel-Lucent, Ericsson, EADS, Sagemcom, Thales, Orange, Telefónica, Vodafone, and British Telecom.
Specific telecommunications projects include:
- “4G and beyond” wideband and cellular systems
- low-data rate and short-range (a few meters) communication systems, such as wireless-sensor and actuator networks
- high-data rate, short-range communication systems for multimedia and other applications
- cognitive radio technologies that automatically select the “best” available radio access
Energy efficiency is a continuing focus of our work in all research. Moreover, we are strongly involved in security and defense programs related to the telecommunication technologies

GreenTouch Initiative : collaborating to radically lower power use of communications networks
Leti is a founding member of the GreenTouchTM Initiative, a consortium of industry, government labs, and academia working on technologies dedicated to making communications networks 1,000 times more energy efficient by 2020.
Benefits for society, industry, and members include:
- Dramatic reductions in energy consumption, carbon footprint and operating costs
- Reinvention of today’s communications networks
- Unprecedented collaboration between leading global experts
- New application of fundamental research
- Opportunities to bring innovative new ideas, products and solutions to market
