Keysight, Ericsson demonstrate pre-6G network

A prototype for early 6G network uses Ericsson’s pre-standard protocol stack tailored for new spectrum bands linked to a test system from Keysight Technologies.

The demonstration establishes a link between an Ericsson basestation testbed and emulated user equipment from Keysight, which is involved in multiple 6G projects across Europe.

The network allows new frequency ranges for 6G wireless communication systems to be evaluated to make use of bandwidth and available spectrum. Using higher spectrum involves overcoming several development challenges, including the well-understood hurdles related to radio frequency (RF) propagation in these bands.

In addition, the current 5G protocol stack will require modifications to support the larger bandwidths and higher carrier frequencies necessary for 6G applications, which have not been tested or deployed in the real world. 

The demonstration is based on Ericsson’s pre-standard 6G concept and tailored for new spectrum bands and represents an initial step toward validating a 6G protocol stack. The modified 5G stack has been created using real-world hardware to establish a connection between a base station and an emulated UE. Starting with a simple digital interface, the teams collaborated to test various aspects of the protocol within the context of wider bandwidths, demonstrating the stack’s potential effectiveness.

“Exploring new frequency bands creates a collaborative environment where diverse players can come together to shape the future contours of connectivity and technological innovation, ensuring that such advanced technologies are integrated seamlessly and sustainably into our connected world,” said Freddie Södergren, Vice President, Head of Technology & Strategy for Business Area Networks at Ericsson.

 Giampaolo Tardioli, Vice President, 6G and Next Generation Technology at Keysight, said: “By working closely with Ericsson throughout the development process, our two teams have been able to rapidly create a working link and show the feasibility of this technology.  The learnings from the project are helping us to ensure that our solutions are 6G capable and ready in time to enable our customers to be first to market.”;
