W8: 5G evolution to 6G – technologies and circuits


14:00 - 17:30

room 4-5


Florinel Balteanu, Skyworks Solutions, USA


The widespread adoption of global 5G smartphones has been made possible, in part, by increased computational capabilities of CMOS technology in lower feature nodes. This has been allowed for significant improvements in RF CMOS through the use of digital signal processing (DSP) and digital calibration. Research efforts to enhance the performance, reduce costs and decrease size of 5G solutions, are highly active and serve as driving force for the semiconductor industry. MmWave frequencies up to 300GHz will play a critical role in future 6G networks. The workshop will address current 5G semiconductor technologies and architectures used in cellular applications, explore challenges facing the deployment of 5G, and discuss prospects for future developments towards 6G.
