Samsung Electronics America and Verizon announced that they have
completed the deployment of 5G systems in five U.S. cities in
preparation for beginning customer trials of 5G technology.
The customer trials will deliver fixed wireless access
to customers through 5G connectivity to gauge user experiences, evaluate
the performance of 5G technologies, and help streamline the delivery of
millimeter wave (mm-wave) 5G across various environments. The 5G trials
involve innovative network systems, including the use of 28-GHz mm-wave
spectrum and advanced beamforming antenna technology.
Samsung’s 5G access units, installed throughout
a city’s business and residential neighborhoods, will link radio
signals to a virtualized core network that is set up within
Verizon’s data centers. Samsung’s next-generation core
solution is software driven and designed on a scalable platform to
accommodate operator needs.
In pre-commercial testing, which began in December
2016, the 5G system demonstrated multi-Gb/s throughputs at radio
distances of up to nearly 500 m across each of the different environments
selected for the customer trials. The Samsung 5G system is designed to be
upgradable to support 3GPP standards for NR and Next-Generation Core,
once available.
Samsung and Verizon 5G customer trials have begun in
New Jersey, Massachusetts, Texas, and Washington, D.C., with a fifth
location in Michigan having started trials as of the second quarter of
2017. Joint trials will incorporate Samsung’s pre-commercial 5G
solution featuring: customer premise equipment, a window antenna, and
its 5G radio and core solutions. Verizon will include a fixed wireless
network service that provides wireless Internet access and
voice-over-Internet-Protocol calling.
Nokia announced the development of a solution that
will allow operators to rapidly address the huge demands of connected
people and industries. Nokia 5G FIRST includes its radio access network
(RAN), packet core, and mobile transport solutions as well as a
full-service offer starting in 2017 using Intel architecture and the
Intel 5G modem for initial deployments. The RAN components of 5G FIRST
comprise new Nokia massive MIMO adaptive antennas for 3.5-, 4.5-, 28-,
and 39-GHz frequency bands, the AirScale system module, AirScale cloud
RAN technology, and software.
Nokia has upgraded its AirScale and AirFrame platforms
to 5G based on specifications developed by the KT Special Interests Group
and Verizon 5GTF. Leveraging Nokia’s end-to-end (E2E) network
capabilities, 5G FIRST also incorporates the multiaccess Nokia Cloud
Packet Core and the Nokia Shared Data Layer as part of a cloud-native
core architecture to deliver the flexibility, massive scalability, and
performance that operators need to rapidly and cost-effectively deliver
5G services.
A comprehensive array of mobile transport offerings
from Nokia addresses the critical capacity, reliability, and latency
requirements of the 5G era. With the introduction of 5G FIRST, operators
will gain a first-to-market advantage based on early specifications.
As a next step in a new technology collaboration with
Intel, Nokia will leverage the Intel 5G modem for initial deployments of
5G FIRST to deliver ultrabroadband to the home using fixed wireless
access as an alternative to existing fiber deployments. To meet
early-adopter demands, Nokia will make its commercial 5G FIRST E2E
solution available in the second half of 2017.
Qualcomm Technologies announced that it is expanding
the Qualcomm Snapdragon X50 5G modem family to include 5G NR multimode
chip set solutions compliant with the 3GPP-based 5G NR global system. The
new members of the Snapdragon X50 5G modem family are designed to support
multimode second-generation (2G), 3G, fourth-generation (4G), and 5G
functionality in a single chip, providing simultaneous connectivity
across both 4G and 5G networks for robust mobility performance.
The single-chip solution also supports integrated
gigabit LTE capability, pioneered by Qualcomm Technologies, and is an
essential pillar for the 5G mobile experience as the high-speed coverage
layer that coexists and interworks with nascent 5G networks. The expanded
Snapdragon X50 5G modem family builds on Qualcomm Technologies’
technology leadership with 5G NR prototype systems as well as joint tests
and trials with leading network operators and network equipment vendors.
Qualcomm’s leadership is exemplified by the
recent announcement of its first 3GPP-based 5G NR Connection using
Qualcomm Technologies’ sub-6 GHz 5G NR prototype. The prototype
demonstrated some of the key technologies and system design principles
expected to be part of the 5G NR system and specification, such as
- Scalable OFDM-based waveforms to support wider bandwidths
- Reciprocity-based multiuser (MU) MIMO
- Advanced low-density paritycheck channel coding
- Adaptive selfcontained TDD subframes
- A new flexible, low-latency slot structure.
