Technology milestone: Showcasing 5G NR interoperability
Ericsson together with Qualcomm and in collaboration with 9 leading telecom operators from different parts of the world conducted a multivendor 5G interoperability test compliant with the approved global 3GPP standard for 5G New Radio (NR) Non-standalone (NSA). The operators include AT&T, NTT DOCOMO, Orange, SK Telecom, Sprint, Telstra, T-Mobile US, Verizon, and Vodafone.
The interoperability demonstrations mark an important technology milestone toward standard-compliant trials. It is also a proof point of the ongoing industry collaboration to accelerate 5G NR for commercial network launches starting 2019.
The live over the air multiband demonstrations 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 demos were conducted for the lower layer data connections. These just standardized layers are fundamental building blocks of 5G NR.
The success of this interoperability test paves the way for commercial launches of 5G standard-compliant infrastructure and devices. Going forward our 5G NR pre-commercial base stations and Qualcomm UE prototypes will enable operators to conduct live tests in their own networks.
The newly approved 3GPP standard for 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.
