NTT demos 100-Gbps wireless transmission

It was shown in a laboratory environment that dramatic leaps in transmission capacity could be 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 in the 28 GHz frequency band. Eleven data signals each at a bit rate of 7.2 to 10.8 Gbps were simultaneously generated and carried by multiple OAM-multiplexed electromagnetic waves, thereby achieving large-capacity wireless transmission at a world-first total bit rate of 100 Gbps.

The results of this experiment revealed the possibility of applying this principle to large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G scheduled for launch. They are expected to contribute to the development of innovative wireless communications technologies for next generation of 5G systems such as connected cars, virtual-reality/augmented-reality (VR/AR), high-definition video transmission, and remote medicine.
