Qualcomm Technologies and NTT DOCOMO on Monday announced they have together enabled the world's first commercialization of 5G sub-6 GHz carrier aggregation (sub6-CA) in Japan, effective immediately.
Deployment of 5G carrier aggregation, a critical capability in 5G specifications, 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 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.
