Samsung Electronics today announced the company will deploy its cloud-native fully virtualised Radio Access Network (vRAN) solutions for the mid-band spectrum in KDDI’s 5G network. Samsung and KDDI have been collaborating on advanced research on vRAN to drive 5G innovation for KDDI’s network. Most recently, the companies successfully completed the first 5G Standalone (SA) call using Samsung’s vRAN and another vendor’s 5G Massive MIMO radios, which are O-RAN compliant.

Powered by Samsung’s vRAN, KDDI’s 5G network is said to deliver exceptional performance, enabling KDDI users to experience the full potential of 5G.

“We are delighted to extend our collaboration with Samsung and to become the first operator in Japan to use their 5G vRAN solutions, which are currently delivering superior performance in commercial networks,” said Kazuyuki Yoshimura, Chief Technology Officer of KDDI.

With its latest 5G vRAN technology, Samsung brings a range of improvements to KDDI’s network. By replacing dedicated baseband hardware with software elements, vRAN offers more deployment flexibility, greater scalability and improved resource efficiency in network operation. With its cloud-native, container-based architecture, Samsung’s vRAN also simplifies end-to-end network management through automation, allowing operators to quickly introduce new services with minimal impact on deployment.

Virtualized networks will play a key role in supporting KDDI’s pursuit of new 5G use cases and next-generation capabilities. Last year, for instance, Samsung and KDDI demonstrated how 5G end-to-end network slicing could play a key role for mobile operators by enabling the creation of multiple virtual networks within a single physical network infrastructure, the company said in a release.

Samsung and KDDI will begin trials in Q1 of 2022, and start commercial deployment in the second half of 2022.
