NTT Docomo is showcasing 31 new technologies for 5G Evolution, 6G, Generative AI and more including some “world-firsts” at its Open House ’24 event in Japan. This includes solutions around mobile backhaul, network slicing orchestration and new AI applications including Feel Tech, which Docomo said is the world’s first technology for sharing taste sensations between individuals via the operator’s “human-augmentation mobile platform”. It also showed its gen AI solution to create non-player characters in the metaverse.

Mobile backhaul

Applications for ‘Beyond 5G’ and 6G are currently under development around the world for mobile backhaul but they require a high-capacity transmission that exceeds 50 Gbps, which is difficult to achieve using conventional wireless communication systems. Docomo is working on orbital angular momentum (OAM) mode-multiplexing radio transmission, which is one of the spatial multiplexing transmission techniques that can meet the demand for high-capacity transmission. Using OAM for transmission, plus high-precision real-time propagation characteristic analysis and channel bonding for bundling and transmitting multiple channels, the operator believes it can work as an ultra-high-speed transmission system using the 100 GHz band.

Network slicing

Docomo has also demonstrated an end-to-end orchestration 5G standalone network slice, using a 5G core network constructed in a hybrid cloud and a commercial 5G wireless base station at its Open House ’24 event in Japan. Working also with NEC, the operator utilised Sandvine’s Active Logic hyperscale data plane and Maestro Policy Engine in its 5G core, providing KPI and KQI visualisation of the QoS/QoE delivered for each slice. 

The ability to provide dedicated slices and to visualize for enterprises that they received the level of service they paid for will be increasingly important in sectors that have low-latency and high-bandwidth demands. The operator also demonstrated a 5G core running on AWS.

To foster 5G adoption in industrial applications, Docomo has also developed an advanced yet portable simulator that makes it easy to visualise 5G wireless transmission characteristics and electromagnetic interference effects in each customer’s unique industrial setting. By making it possible to easily investigate electromagnetic interference, it promotes safe and secure use of radio waves even in medical settings and other places where delicate equipment is handled.

In air and under water

In addition, the operator showcased its latest technologies for non-terrestrial network (NTN) HAPS and underwater drones for mobile coverage beyond the reach of conventional terrestrial network areas, from remote seas to low-orbit space.
