Record-breaking 100Gbps wireless transmission is a world first

Nippon Telegraph and Telephone Corporation (NTT) has successfully demonstrated the world’s first 100Gbps wireless transmission, using a new technology that already surpasses the upcoming 5G standard.

But this new tech, called Orbital Angular Momentum (OAM) multiplexing, isn’t likely to roll out on a large scale before 2030.

The technical feat was part of NTT’s laboratory experiments. NTT conducted transmission experiments at a distance of 10 meters using a system operating in the 28GHz frequency band.

In total, NTT simultaneously generated 11 data signals, each at a bitrate of 7.2 to 10.8Gbps, achieving large-capacity wireless transmission at 100Gbps, a world first.

This level of wireless capacity reaches a level around 100 times that of LTE and Wi-Fi, and about five times that of 5G, launching in 2020.

In the short-to-medium term, this technology could be used to help boost 5G performances for new domestic uses requiring higher transmission capacities (autonomous and connected vehicles, VR, high-definition video transmission, etc.).

NTT will present the results at Wireless Technology Park 2018 in Tokyo, Japan, May 23 to 25. Although the concept is still relatively new, the successful experiment paves the way for a host of exceptional possibilities. JB
