Bringing high-speed internet access to sparsely-populated rural areas can be a challenge when you only have access to non-contiguous frequency bands—unless you have Leti’s BF-OFDM technology, that is*! Leti just rolled out the technology in Scotland’s Orkney Islands on a test basis, where it was a success. Compared to the OFDM waveforms used in 4G […] >>

Leti showed off its anti-collision-system prototype for drones at CES 2018. The system is the world’s first to provide 360-degree protection from stationary and moving obstacles. Infrared laser sensors detect obstacles, while an algorithm implemented on a commercially-available microcontroller fuses the data and corrects the drone’s trajectory. The complete system weighs in at less than […] >>

A team of researchers from INAC and Institut Néel developed UV and IR photodetectors offering unrivalled performance. The devices are based on a single gallium nitride nanowire. The first, which detects UV B rays, is three times more responsive than the current state of the art. The second can detect IR rays in 100 femtoseconds […] >>

The indicators used to diagnose sleep apnea—heart and respiratory rates, stress, blood oxygen level—can now be measured at home with a simple wristband. Leti showcased the innovative device at CES 2018 and is working with manufacturing partners to get the product out to medical professionals. The complete solution includes the wristband (with optical and electrical […] >>

Researchers at INAC doped sheets of graphene with nitrogen in an ECR-CVD reactor,* obtaining a record atomic concentration of 17% nitrogen. The graphene sheets were then used to make a button-battery-format ultracapacitor. The ultracapacitor offers state-of-the-art power and energy levels, is very stable, and can power a LED for seven minutes on just a twenty-second […] >>
