SoftBank increases data speeds by 40% with Ericsson Elastic RAN

Results from deployment of Ericsson Elastic RAN deployed in Tokyo station area showed downlink user data throughput increased by up to 40% during peak hours

SoftBank increases data speeds by 40% with Ericsson Elastic RAN

Ericsson successfully completed the first commercial implementation of its Elastic Radio Access Network (RAN) for SoftBank's mobile network in Japan. Elastic RAN is included within the Ericsson Cloud RAN solution and was developed specifically to improve users' mobile broadband experience through elastic co-ordination of users and cells.

With Ericsson Elastic RAN, an unlimited number of cells can be co-ordinated across the entire network providing great flexibility in the aggregation of the different network cell carriers independent of user location. Co-ordinating and aggregating cell carriers improves user data speeds and overall network performance.

The results of the Tokyo train station commercial implementation show that downlink throughput increased by up to 40% during peak hours for commuters with three carrier aggregation enabled smartphones.

Mikael Eriksson, Head of Ericsson Japan, said: “Tokyo presents a challenging network environment with very high mobile data usage with short distances between cell sites. This makes inter-cell co-ordination complex, which is critical to the aggregation of cell carriers required to achieve high performance. Elastic RAN introduces a new paradigm with respect to the way we achieve inter-cell co-ordination by creating borderless co-ordination areas."

Hideyuki Tsukuda, Senior Vice President and Deputy Head of Technology Unit, SoftBank Corp., said: "The Japanese market is highly developed, and our customers enjoy using the latest mobile broadband technologies with their smartphones and applications.

“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. We are now expanding Elastic RAN deployment to further deliver high performance throughout our network."
