SoftBank and Huawei Technologies Japan have jointly demonstrated various potential use cases for a 5G network, which provides ultra-high throughput, ultra-low latency transmission, and edge computing, to SoftBank's business partners.
The demonstration included real-time UHD video transmission using ultra-high throughput, remote control of a robotic arm using ultra-low latency transmission and remote rendering via a GPU server using edge computing. The real-time UHD video transmission demonstrated throughput of over 800 Mbps. Also, the remote control of the robotic arm demonstrated an ultra-low latency one-way transmission of less than 2ms.
SoftBank is planning various experiments to study 5G technologies and is endeavoring to launch 5G commercial services around 2020.
In edge computing, servers are located near by base stations, i.e. at the edge of an mobile network, with a distributed way. This architecture allows us to realize ultra low latency transmission between the servers and mobile terminals. Also, it is possible to process a huge amount of data gathered by IoT devices to decrease the load of the mobile network.
