Global Mobile Industry Leaders Achieve Multi-Band 5G NR Interoperability

By Ken Briodagh December 21, 2017

An important technology milestone based on the newly-approved NSA 5G NR standard has been achieved by a group of mobile communications companies, according to a recent announcement. Ericsson and Qualcomm, in collaboration with AT&T, NTT DOCOMO, Orange, SK Telecom, Sprint, Telstra, T-Mobile (News - Alert) US, Verizon, and Vodafone, recently showcased 3GPP-compliant 5G NR multi-vendor interoperability during live demonstrations in both the Ericsson Lab in Kista, Sweden and the Qualcomm Research lab in New Jersey, USA.

“This milestone builds on years of researching and developing 5G technology as well as on leading and contributing to the standardization work,” said Fredrik Jejdling, EVP and Head of Business Area Networks, Ericsson (News - Alert). “By working closely with our key partners in early trials and fine-tuning our global portfolio, we ensure that we can bring the standard-compliant technology to the benefits of our customers and their customers.”

The successful demonstrations pave the way for commercial launches of 5G standard-compliant infrastructure and devices. Ericsson’s 5G NR pre-commercial base stations and Qualcomm Technologies’ 5G NR UE prototypes are designed to enable operators to conduct live tests in their own networks.

“Achieving multi-vendor interoperability based on the global 5G NR standard is a true testament to our continued 5G leadership, delivering fundamental contributions to the 3GPP standard and driving toward the launch of standard-compliant commercial networks and devices starting in 2019,” said Cristiano Amon, EVP, Qualcomm Technologies, and president, QCT. “As we did in both 3G and 4G, we are excited to collaborate with Ericsson as an industry leader to accelerate the path to 5G globally.”

The over-the-air Interoperability Development Testing (IODT) was conducted for lower layer data connections operating at both 3.5 GHz and 28 GHz bands. These just standardized layers are the fundamental building blocks of 5G NR. NSA 5G NR will use the existing LTE radio and evolved packet core network as an anchor for mobility management and coverage while adding a new 5G NR radio access carrier to enable certain 5G use cases starting in 2019.

“The network of the future is being built – and it’s happening fast. We’re proud to be one of the top North American wireless carrier contributors into 3GPP’s work on 5G standards and to be part of the group of companies that advocated for standards acceleration earlier this year,” said Marachel Knight, SVP Wireless Network Architecture Design, AT&T (News - Alert). ”We’re excited to be a part of standards-based interoperability testing as this helps speed up development of 5G devices and hardware and helps pave the way to launch standards based 5G NR service as soon as the end of 2018.”

“Tremendous progress is being made in the development of 5G NR for our sub-6 GHz spectrum, the largest such block available for wide-scale use in the United States,” says Dr. John Saw, Sprint CTO. “We see great opportunity in mobile 5G, massive machine type communications, and ultra-reliable and low-latency communications. Cloud robotics, connected cars and drones, augmented and virtual reality – these are just the start of the applications that will drive new levels of innovation and progress around the world.”

“This achievement is a major step forward toward our commitment to build a nationwide 5G network by 2020 and bring 5G to our customers,” says Neville Ray (News - Alert), Chief Technology Officer for T-Mobile. “The demonstration used both millimeter wave and spectrum below 6GHz – proving the Un-carrier vision that spectrum across all bands will be used for 5G.”

Verizon (News - Alert) was pleased to participate in the successful 5G NR multi-vendor interoperability demonstrations," says Ed Chan, Chief Technology Architect and Network Planning. He added, "These demonstrations represent a key milestone in moving us another step closer towards commercial availability of 5G mobile services for customers."

Luke Ibbetson, Vodafone’s Head of Group R&D, says: “This first multi-vendor interoperability test of 5G within days of the completion of the 3GPP standard paves the way for Vodafone to trial commercial grade equipment in the coming year. 5G has the potential to provide up to a ten-fold improvement in cost efficiency to help us meet the growing demand for mobile data from Vodafone customers. The capabilities delivered by 5G will also help create the Gigabit societies of the future.”

The IODT test complies with the following key characteristics of the 3GPP 5G NR specifications:
