Mobile Industry Leaders Achieve Multi-band 5G NR Interoperability

Mobile Industry Leaders Achieve Multi-band 5G NR Interoperability

An important technology milestone based on the newly-approved NSA 5G NR standard has been achieved by a group of leading mobile communications companies.

Ericsson  and Qualcomm, in collaboration with AT&T, NTT DOCOMO, Orange, SK Telecom, Sprint, Telstra, T-Mobile US, Verizon, and Vodafone, showcased 3GPP-compliant 5G NR multi-vendor interoperability during live demonstrations held in both the Ericsson Lab in Kista, Sweden and the Qualcomm Research lab in New Jersey, USA.

The successful demonstrations show the companies’ combined strength in carrying out timely trials that pave the way for commercial launches of 5G standard-compliant infrastructure and devices. Ericsson’s 5G NR pre-commercial base stations and Qualcomms’ 5G NR UE prototypes will enable operators to conduct live tests in their own networks.

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.
