Telefonica showcases 5G network slicing technology at MWC

Telefonica said it’s taking advantage of its appearance at MWC to demonstrate the concept of end-to-end network slicing, which the operator said is one of the great assets of 5G technology, as part of its ongoing cloud-based Unica virtualisation project. The tests conducted at MWC served to showcase the possibility of delivering simultaneously distinct network capabilities adapted to different types of service using a common infrastructure, said Telefonica, adding that the demos included one for connectivity, one for critical communications and one showing the use of augmented reality for remote assistance in the digital industry sector.

The operator used 5G spectrum in the 3.7 GHz band for the demos, which presented advanced use cases working on different network slices built on Telefonica’s virtualised network. In collaboration with Huawei, Ericsson and Netsia, the use cases include a virtual reality experience based on the “Digital Twins” concept, where objects from the physical world are reproduced virtually in real time, and an augmented reality demo where a real image is produced on the screen using virtual images.

The third demo uses RAN slicing technology to create a private LTE network with the ability to be sub-divided into multiple slices which, at RAN level, can offer different performances, latencies and radio resources to different sets of customers, said Telefonica.

Huawei added that the VR demo it conducted with Telefonica showed how 5G network slicing can enable on-demand diversified services and ensure large bandwidth and low latency. The test used 5G end-to-end (E2E) network slicing technology, including the access network, core network, transport network and terminals, as well as the world's first 5G commercial CPE.
