Qualcomm Technologies and NTT DOCOMO have commercialized the use of sub-6 GHz 5G carrier aggregation (sub6-CA) in Japan, effective immediately, to bring multi-gigabit mobile experiences to DOCOMO customers. Deployment of 5G carrier aggregation, a critical capability in the 5G specification, is enabling customers to now enjoy improved performance on DOCOMO’s rapidly expanding 5G network.
Using DOCOMO’s new 5G network and select devices powered by the Qualcomm® Snapdragon™ 865 Mobile Platform with the Snapdragon X55 5G Modem-RF System, customers can now enjoy mobile download speeds of up to 4.2 Gbps – the fastest speeds available in Japan. This level of service is achieved through 5G sub-6 GHz carrier aggregation, which combines a 100 MHz carrier in band n78 and a 100 MHz carrier in band n79 to boost 5G performance and network capacity using DOCOMO’s diverse spectrum assets.
The deployment of 5G Sub6-CA, along with the 5G mmWave 28 GHz band that DOCOMO began operating commercially in September, will unleash the full potential of 5G and enable accelerated deployment of DOCOMO’s 5G service areas.
“It is a pleasure to continue our work with DOCOMO to advance and accelerate 5G technology throughout Japan,” said Durga Malladi, senior vice president and general manager, 4G/5G, Qualcomm Technologies, Inc. “By providing access to breakthrough technologies like 5G carrier aggregation, we are enabling consumers and companies throughout Japan to access faster connectivity, enhanced capacity and better reliability.”
“In collaboration with Qualcomm Technologies, we are pleased to begin delivering this advanced and groundbreaking mobile technology to our customers nationwide,” said Naoki Tani, executive vice president and chief technology officer, NTT DOCOMO. “DOCOMO subscribers can now enjoy superior 5G service together with exciting mobile experiences. Moreover, by establishing a new standard of possibility for the industry, we are proud to help initiate a new era of connectivity in Japan.”
