5G New Radio (NR) data calls in new 3.7GHz and 28GHz spectrum bands are compliant with 3GPP release 15 specifications
Fujitsu Limited and Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, have achieved non-standalone (NSA) 5G New Radio (NR) data calls on sub-6 GHz and mmWave spectrum bands1. The two parties successfully conducted Network-Device Vendor Interoperability Testing (NV-IOT) for NTT DOCOMO, INC., leveraging Fujitsu's commercial 5G base station (gNB) products together with a mobile smartphone form-factor test device, powered by the Qualcomm Snapdragon X50 5G modem and antenna modules with integrated RF transceiver, RF front-end and antenna elements.
These latest NV-IOT testing bi-directional data calls, compliant with the 3GPP release 15 specifications, were completed in mid-July at Fujitsu in Japan.
This achievement marks a significant milestone to build a successful 5G end-to-end ecosystem in Japan, composed of 5G network infrastructure from Fujitsu and a broad range of 5G user devices using Qualcomm Technologies' modems and RF Front-end solutions.
"These data calls bring 5G technology one step closer to commercial rollout," said Durga Malladi, Senior Vice President and General Manager, 4G/5G, Qualcomm Technologies, Inc. "These live tests deliver on the commitment of Qualcomm Technologies and Fujitsu to make 5G a commercial reality in 2019 and are major milestone in driving 5G network launches around the world. We look forward to continuing our collaboration with Fujitsu, enabling 5G networks and providing consumers with transformative 5G experiences starting this year."
"5G networks will accelerate Fujitsu's human centric innovations through co-creation with our customers," said Masayuki Seno, Senior Vice President, Head of Network Products Business Unit, Fujitsu Limited. "We have been developing gNB products (O-CU, O-DU and O-RU) compliant with global specifications and O-RAN fronthaul interfaces2. Going forward, Fujitsu will perform further interoperability tests together with Qualcomm Technologies to make significant strides in developing 5G commercial network products."
Fujitsu and Qualcomm Technologies look to continue to strengthen relationships with companies that aim to provide 5G commercial services. Accordingly, the two companies are committed to support customers worldwide - encouraging the development of digital technologies and new innovative services utilizing the fast speeds, large capacity and ultra-low latency supported by 5G.
