Next-generation wireless communication technologies will no longer be limited to connecting people with objects but will expand to include cooperation amongst intelligent vehicles or robots that will not involve human intervention. Current communication systems are relatively expensive, have limited bandwidth or feature power-hungry hardware that is not compatible with autonomous systems. The EU-funded HERMES project proposes fusing artificial intelligence and deep sub-micron CMOS technology to develop a new generation of wireless transceivers. Focusing on sub-terahertz frequencies between 140 and 160 GHz, the project will break new ground in data conversion in the sub-terahertz spectrum for applications far-beyond 5G.
