Ericsson has completed the first commercial deployment of its new Elastic RAN for Japan's SoftBank, and entered an agreement to build a 5G trial network in parts of Tokyo with NTT DoCoMo and Intel.
SoftBank has implemented Ericsson's Elastic RAN at Tokyo station, one of the biggest train stations in the world.
The deployment allows for an unlimited number of cells to be co-ordinated across a network to improve flexibility in the aggregation of different network carriers.
Ericsson said tests indicate that downlink throughput has increased by up to 40% during peak hours for commuters using three-carrier aggregation compatible smartphones.
“The Japanese market is highly developed, and our customers enjoy using the latest mobile broadband technologies with their smartphones and applications,” SoftBank SVP and deputy head of technology Hideyuki Tsukuda said.
“We are excited to partner with Ericsson in the first introduction of the Elastic RAN solution to enable peak performance of the most advanced smartphones in the world, in the densest and most challenging areas of our network.”
He said SoftBank plans to continue deploying the RAN across these dense urban areas.
Ericsson separately announced an agreement with DoCoMo and Intel to build a 5G trial network in parts of the city from 2017.
Ericsson will provide 5G radio, baseband, virtualized RAN and core networks, while Intel will contribute its chipset in user devices. The trial will use the 28-GHz spectrum band that the Japanese government is considering designating for 5G use.
