NEC contributes to 5G test by NTT Communications, NTT DOCOMO and TOBU RAILWAY

4K and 8K high-definition videos were transmitted from a 5G base station installed along the railroad,

corresponding to the 4.5 GHz band and 28 GHz band, to a 5G mobile station located inside a train running at approximately 90 km/h and projected on a large display in real time.

In addition, the videos were transmitted to 40 smartphones on the train via wireless LAN.

The NEC 5G base station was equipped with a Massive MIMO antenna, which forms beams (directivity) that concentrate power on the location and direction of the 5G mobile station.

Since the antenna always forms optimal beams for a mobile station by making the beams track the mobile station in motion, it is capable of realizing a high-data transmission rate and high-quality wireless data communication, even for a mobile station installed inside a moving train, as in this demonstration.

This demonstration of 5G enables the transmission of high-presence and high-definition video content, even on a train or a bus in motion, providing a service that allows the distribution of large-capacity content in a variety of media, regardless of the location or situation.
