W1: Technologies and Circuits for 5G evolution to 6G





10:00 - 12:30



Room 1.06


The research area of improving the performance, cost and size of 5G RF solutions and evolution to 6G is very active with many developments and it is one of the driving factors for semiconductor industry. Mobile cellular subscribers reached more than 6 billion in 2022 and 5G LTE brings high data capacity as low latency using sub-6GHz and mm-Wave spectrum. Mm-Wave up to 300GHz will play a major role in future 6G networks. The proliferation of worldwide smartphones has been in part possible due to increased computational power of CMOS technology in lower feature nodes as 3nm/7nm. This has made also possible to essentially enhance RF CMOS through digital signal processing (DSP) and digital calibration. The workshop will cover 5G semiconductor technologies and architectures currently used in RF applications and the challenges for the 5G deployment as well the evolution to 6G.
