Keysight and Ericsson Showcase Pre-6G Network Technology

A groundbreaking prototype for an early 6G network has been unveiled, showcasing the innovative collaboration between Ericsson and Keysight Technologies. This pioneering project utilizes Ericsson's pre-standard protocol stack, specifically designed for new spectrum bands, in conjunction with a test system from Keysight. The successful demonstration establishes a crucial link between an Ericsson basestation testbed and emulated user equipment from Keysight, marking a significant milestone in the development of 6G technology.

The primary objective of this demonstration is to evaluate the feasibility of utilizing new frequency ranges for 6G wireless communication systems. By harnessing these untapped spectrum resources, the network aims to maximize bandwidth and optimize available spectrum for enhanced connectivity. However, the transition to higher spectrum bands presents a unique set of challenges, particularly in overcoming obstacles related to radio frequency (RF) propagation within these bands.

One of the key highlights of this project is the necessity to modify the existing 5G protocol stack to accommodate the larger bandwidths and higher carrier frequencies essential for 6G applications. These modifications are crucial for ensuring seamless integration of advanced technologies into the evolving landscape of wireless communication. Despite not yet being tested or deployed in real-world scenarios, the adapted protocol stack represents a significant step towards validating the foundation of 6G networks.

The demonstration is based on Ericsson's cutting-edge pre-standard 6G concept, tailored to exploit new spectrum bands and pave the way for future innovations in wireless communication. By leveraging real-world hardware, the teams have successfully established a connection between a base station and an emulated UE, showcasing the potential effectiveness of the modified 5G stack. Through collaborative efforts and rigorous testing, the project has provided valuable insights into the performance of the protocol stack within the context of wider bandwidths.

Freddie Södergren, Vice President, Head of Technology & Strategy for Business Area Networks at Ericsson, emphasized the collaborative nature of exploring new frequency bands, stating, "Such initiatives create a collaborative environment where diverse stakeholders can shape the future of connectivity and technological innovation. It is essential to ensure that these advanced technologies are seamlessly integrated into our connected world." Giampaolo Tardioli, Vice President of 6G and Next Generation Technology at Keysight, echoed this sentiment, highlighting the rapid progress achieved through close collaboration with Ericsson and the importance of readiness for the 6G era.
