Verizon and Samsung complete fully virtualized 5G data session on C-band spectrum
27 Julio 2021 - 8:30AM
Verizon and Samsung Electronics Co.c, Ltd. recently completed an
end-to-end fully virtualized 5G data session over C-band spectrum
in a live network environment. The new milestone was reached in
preparation for its upcoming 5G Ultra Wideband expansion using its
newly acquired C Band spectrum.
“We have been driving the industry to large scale virtualization
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,” said
Adam Koeppe, Senior Vice President of Technology Planning at
Verizon. “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.”
Why Virtualization is important for 5G performance
optimization
The trials, conducted over Verizon’s network (using C-band
Special Temporary Authority granted to Verizon by the FCC) in
Texas, Connecticut and Massachusetts, 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.
Virtualization is critical to delivering the services promised
by advanced 5G networks. Key 5G use cases such as massive scale IOT
solutions, more robust consumer devices and solutions, AR/VR,
remote healthcare, autonomous robotics in manufacturing
environments, and ubiquitous smart city solutions, will heavily
rely on the programmability of virtualized networks.
Cloud native virtualized architecture leads to greater
flexibility, faster delivery of services, greater scalability, and
improved cost efficiency in networks, paving the way for wide-scale
mobile edge computing and network slicing. This technology enables
Verizon to rapidly respond to customers’ varied latency and
computing needs. Virtualization will also lower the barrier to
entry for new vendors in the ecosystem. New entrants will
accelerate innovation, reduce operating costs, and lay the
groundwork for flexible network and cloud infrastructure closer to
the customer, eventually leading to single digit millisecond
latency.
“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,”
said Junehee Lee, Executive Vice President and Head of R&D,
Networks Business at Samsung Electronics. “This achievement
represents our dedicated efforts in leading the transition to
virtualization, and helping Verizon realize greater efficiency,
scalability and flexibility. vRAN is a powerful enabler for network
transformation, and we aim to continue leading this journey.”
Why Massive MIMO is important for 5G performance
optimization
Massive MIMO is an evolution in antenna arrays that uses a high
number of transmitters which enables more possible signal paths
between a device and a cell tower. It also reduces interference
through beamforming, which directs the beam from the cell site
directly to where the customer is resulting in higher and more
consistent speeds for customers using apps and uploading and
downloading files. This trial used Samsung’s C-band 64T64R Massive
MIMO radios that support digital/dynamic beamforming, SU-MIMO,
MU-MIMO and dual connectivity and carrier aggregation.
“Incorporating full, cloud-native virtualization, Massive MIMO
and beamforming into our network design and deployment will result
in so much more than our customers merely seeing a 5G icon on their
devices. This is 5G service optimized for peak performance,” said
Koeppe.
Today’s milestone follows Samsung’s recent announcement on
expanding its vRAN capability to support mid-band Massive MIMO
radios—a first for the industry. Samsung’s C-band Massive MIMO
radio is part of a complete C-band solutions portfolio.
Verizon on track to deliver 5G over C-band
This virtualization work comes on the heels of other work to
speed the expansion of 5G Ultra Wideband service using C-band
spectrum including:
- successful trials integrating C-band with mmWave licensed
spectrum,
- securing new agreements with Verizon’s tower partners, Crown
and SBA Communications, which provide for process improvements
including standardizing and reducing forms and minimizing legal
reviews, and
- installation of C-band equipment from Ericsson and Samsung
Electronics Co.
These combined efforts, along with ongoing lab and field trials
to optimize 5G technology on C-band spectrum will allow Verizon to
offer expanded mobility and broadband services to millions more
consumers and businesses as soon as the spectrum is cleared.
In the first quarter of 2022, Verizon expects to put into
service the new 5G C-band spectrum in the initial 46 markets and to
provide 5G Ultra Wideband service to 100 million people. Over 2022
and 2023, coverage is expected to increase to more than 175 million
people and by 2024 and beyond, when the remaining C-band spectrum
is cleared, more than 250 million people are expected to have
access to Verizon’s 5G Ultra Wideband service on C-band
spectrum.
