NTT first to demo 100 Gbps wireless transmission

TOKYO - Nippon Telegraph and Telephone Corporation (NTT) said that it can demonstrate 100 Gbps wireless transmission using a new principle, Orbital Angular Momentum (OAM) multiplexing, with the aim of achieving terabit-class wireless transmission to support demand for wireless communications in the 2030s.The company said Wednesday that the dramatic leaps in transmission capacity were achieved by an NTT-devised system that mounts data signals on electromagnetic waves generated by this new principle of OAM multiplexing in combination with widely used Multiple-Input Multiple-Output (MIMO) technology.NTT conducted transmission experiments at a distance of 10 meters in the laboratory using the devised system operating...
