SoftBank boosts data speeds by 40 percent in Tokyo station implementing Elastic RAN

Japan –

Ericsson has successfully completed the first commercial implementation of Ericsson Elastic RAN for SoftBank’s mobile network in Tokyo station area, one of the busiest train stations in the world.

As a result, SoftBank witnessed downlink user data throughput increasing by up to 40 percent during peak hours for commuters with three carrier aggregation enabled smartphones. To further enhance the user’s mobile broadband experience, SoftBank has planned similar deployments throughout dense urban areas across SoftBank’s 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 coordination of users and cells.

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

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.”

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 coordination 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 coordination by creating borderless coordination areas. We are pleased to work with SoftBank to meet their customers’ evolving and ever-expanding needs.”
