SK Telecom and Samsung announced that they have successfully completed the network device interoperability test applying Dual Connectivity technology using both 4G and 5G networks provided by Samsung’s Networks Business. It is also known as ‘E-UTRAN New Radio Dual Connectivity (EN-DC)’ based on the 3GPP 5G New Radio (NR) standard.
During the test, both companies have successfully achieved 2.65Gbps in data speeds on the 5G smartphone, combining both 1.5Gbps in 5G using 3.5GHz frequency (100MHz bandwidth) with 1.15Gbps in LTE using 1.8GHz, 2.1GHz, and 2.6GHz frequencies (65MHz bandwidth) all of which are for commercial use by SK Telecom.
The test in Suwon, Korea, used Samsung’s commercial 4G and 5G NR end-to-end networks solutions which have been provided to the operator’s current service. In addition, companies used Samsung’s virtual core (vCore) that supports simultaneous 4G and 5G as well as its Galaxy S10 5G, Samsung’s first 5G smartphone which was unveiled last month.
SK Telecom, in particular, will be able to boost the overall transmission data speed by 80% by leveraging the 4G and 5G dual connectivity. It will allow users who are staying in the 5G service coverage to download UHD videos of 2GB in just 6 seconds, and large video content such as 4K VR video of 10GB in less than 30 seconds. The success of the demonstration by SK Telecom and Samsung signifies a blueprint of early 5G deployment, spotlighting a rapid, stable and effective path to 5G service using a dual 4G and 5G approach.
Nokia and SURF, the organization for IT in Dutch education and research, have successfully reached a single carrier 800Gb/s optical transmission over SURF’s existing cross-border, multi-vendor research and education network infrastructure.
Nokia and Vodafone are collaborating to test the viability of L4S technology over passive optical networks (PON).
The GSMA believes that critical reform of European laws is necessary to position the region as a technology frontrunner by 2030.
