Nippon Telegraph and Telephone Corporation (NTT)
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.
This is the first time OAM multiplexing has been used for wirelessly transmitting such a high data rate. The eventual aim of this project is to achieve terabit-class wireless transmission to support the demand for wireless communications in the 2030s.
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 WiFi, 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 23-25. Although the concept is still relatively new, the successful experiment paves the way for a host of exceptional possibilities.
