innovation for industry
GRENOBLE, France – May 7, 2020 – As countries around the world begin rolling out 5G wireless networks, CEA-Leti is looking ahead to sixth-generation technologies that will surpass the data-transfer capability of 5G.

Severe constraints on antenna directivity and alignment
Challenges to using D-band wireless communication include free-space wave-propagation losses that increase with the square of the frequency and have to be compensated for using high-gain antennas. That entails severe constraints on antenna directivity and alignment," said Jean-Baptiste Doré, a CEA-Leti scientist and one of the authors of the paper.
For device-to-device communication, we have demonstrated that is possible to reach multi-Gbps throughput using spatial multiplexing and a simple RF architecture," Doré said. "The main outcome is that with the proposed mixed-signal, analog & digital, the required power delivered by transistors is limited to microwatts (10^-6 Watts) which makes CMOS technologies possible.
