Verizon, Samsung complete 5G data session on C-band spectrum

Verizon and Samsung’s 5G data session, completed over the C-band spectrum, used cloud-native, end-to-end virtualisation to optimise network performance

U.S telecom Verizon, in partnership with Samsung Electronics, has completed a trial of a 5G data session over the C-band spectrum. The test was conducted in a live network environment using cloud-native, end-to-end virtualisation in preparation for Verizon’s 5G Ultra Wideband expansion. 

Adam Koeppe, Senior Vice President of Technology Planning at Verizon, said: “We have been driving the industry to large-scale virtualisation using the advanced architecture we have built into our network from the core to the far edge. This recent accomplishment paves the way for a more programmable, efficient, and scalable 5G network. “Customers deserve more than mere access to 5G. They deserve 5G built with the highest, gold-standard engineering practices that have positioned Verizon as the most reliable industry leader for years.”

The importance of virtualisation in optimising 5G network performance 

According to Samsung, Virtualisation plays a vital role in delivering advanced 5G network services. This is due to 5G use cases such as IoT solutions, more robust consumer devices and solutions, AR/VR, remote healthcare, autonomous robotics in manufacturing environments, and ubiquitous smart city solutions, becoming more dependant on the programmability of virtualised networks. 

Pleased with the result of the trial, Junehee Lee, Executive Vice President and Head of R&D, Networks Business at Samsung Electronics, said: “We’re proud to mark another milestone following our first large-scale commercial 5G vRAN deployment for Verizon, which is currently servicing millions of users. This trial reinforces our commitment to helping operators evolve their advanced 5G networks.”

The trials used Samsung’s fully virtualized RAN (vRAN) solution built on its own software stack and C-band 64T64R Massive MIMO radio in coordination with Verizon’s virtualized core. “The trials achieved speeds commensurate with traditional hardware-based equipment,” the companies said.

Verizon claims that cloud-native, virtualised architecture provides greater flexibility aster delivery of services, greater scalability, and improved cost efficiency in networks”, allowing it to lead the way in network slicing and wide-scale mobile edge computing. 

The technology also enables Verizon to respond quickly to customer’s latency and computing needs. Virtualisation aims to lower the entry barrier for new vendors in the ecosystem while entrants will be able to accelerate innovation and reduce operating costs, the companies said. 

Verizon is planning to make the 5G C-band spectrum initially available to 46 markets by the first quarter of 2022, and provide the Ultra-Wideband service to 100mn people. Throughout the next two years, the company expects coverage to increase to 175mn people before reaching 250mn by the end of 2024.
