Ericsson and Qualcomm, in collaboration with leading mobile operators recently showcased a 3GPP-compliant 5G NR multi-vendor interoperability based on standard that was completed this week by the 3GPP..

AT&T, NTT DOCOMO, Orange, SK Telecom, Sprint, Telstra, T-Mobile US, Verizon, and Vodafone, also participated in the live demonstration which showcased both sub-6 GHz and mmWave end-to-end 5G NR systems, using Ericsson’s 5G NR pre-commercial base stations and Qualcomm Technologies’ 5G NR UE prototypes.

The demonstration took place in both the Ericsson Lab in Kista, Sweden and the Qualcomm Research lab in New Jersey, USA.

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.  

Fredrik Jejdling, EVP and HEad of Business Area Networks, Ericsson
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.

Cristiano Amon, EVP, Qualcomm Technologies 
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.
