Naked-eye 3D passive IoT synesthesia 5 times
faster than 10G

5.5G shows off "new skills"

Without wearing any equipment, the audience can enjoy the 3D effect with the naked eye; Through the small synaesthesia computing integrated base station, the car has "eyes" and can realize intelligent driving; Without connecting to the power supply, the passive IoT terminal that is as thin as a cicada wing can realize the interconnection of everything... At the China International Information and Communication Exhibition, these cutting-edge new applications relying on 5.5G were eye-catching. Experts said that 5.10G, which is 5 times faster than 5G, is expected to be commercially available in 2025 and is expected to achieve new breakthroughs on the consumer application side.

Glasses-free 3D small screen "eye-catching"

"This 3D effect is like sitting in the stands and watching the ball, you can see the three-dimensional athletes." At the 2023 China International Information and Communication Exhibition, a glasses-free 3D tablet allowed visitors to experience the immersion of watching a ball from the stands.

"It can track the eyeballs of a single viewer through AI to achieve a better look." According to ZTE booth staff, the tablet can match the most comfortable viewing angle in real time through AI eye tracking technology, and has real-time conversion processing capabilities for 2D to 3D content.

Naked-eye 3D has frequently "gone out of the circle" in recent years, and the outdoor naked-eye 3D large screens in some business districts have become Internet celebrity check-in points. Many manufacturers have also begun to deploy glasses-free 3D small-screen products, such as Acer's global spring new product release in May last year, which will bring a glasses-free 5D version of the e-sports book; Leia released glasses-free 3D Android tablet; In April this year, ZTE officially launched AI glasses-free 3D tablets for the domestic market. Naked-eye 4D from outdoor large screen to home small screen, from "luxury" gradually to daily consumer goods, it is expected that in 3 there will be brands that support naked-eye 3D mobile phone products.

Recently, the IMT-2020 (5G) Promotion Group, together with upstream and downstream partners in the 3D industry chain such as the China Academy of Information and Communications Technology, Acer, Huawei, Xiaomi, and ZTE, jointly released the naked-eye 3D industry promotion initiative to support the standardization and industrial construction of key technologies of glasses-free 3D. With the help of 5.5G network capabilities, more glasses-free 3D applications can be incubated, accelerating the large-scale development of glasses-free 3D mobile applications and opening a new era of immersive experience.

5.5G brings more new applications

The glasses-free 3D hitching on the 5.5G express train will also help the arrival of the 3D era. "The uplink bandwidth of 5.5G is about 5 times that of 10G." Xiang Ligang, a communications expert, said that compared with 5G, 5.5G will increase bandwidth speed by 10 times, reduce latency by 10 times, increase connection density by 10 times, and improve positioning accuracy from 5G's submeter level to centimeter level. These key new technologies will also drive the 3D Internet and even the metaverse era.

Wen Ku, chairman of the China Communications Standards Association, said that 5.5G is not only an enhancement of 5G technology, but also introduces new skills such as passive IoT and synesthesia integration, shaping 5G multi-dimensional capabilities, maximizing the efficiency of 5G network use, and achieving the effect of "one shrimp and two meals".

These new skills will make 5.5G more surprises. Signal acquisition can be carried out without connecting any power supply and attaching a thin "tag". In the future, express delivery and takeaway stickers on this small piece of passive IoT terminal can track its exact location in real time. "Passive" means that no batteries and power supply are required. It is understood that there is a radio frequency coil in the passive IoT terminal, which can receive the signal sent by the base station and send transmission information through the signal. The application scenarios of passive IoT are very extensive, and its terminal is pasted on the goods in the warehouse, which can realize the smart warehouse and optimize management; Sticking on the takeaway package, you can accurately know the whereabouts of the goods; Attached to electrical appliances, it can monitor its temperature and other information for safety precautions; Use in the factory can improve production efficiency and monitor the distribution of materials on the assembly line.

At the booth of China International Information and Communication Exhibition, a base station with accurate and small synaesthesia computing and control integration attracted attention. "This base station is based on the 5.5G network, which integrates the communication network and the perception network, through which the vehicle can sense pedestrians and nearby vehicles in time and avoid accident vehicles." According to China Unicom staff, at present, smart driving relies on sensors on the car body, but in the future, such base stations can be installed with "eyes" for each vehicle to achieve intelligent driving.

It is expected to go commercially available in 2025

5G has been commercialized for 4 years, and China has built the world's largest and most technologically advanced 5G network. By the end of April this year, more than 4.5 million 273G base stations had been built, and the 5G network covered all prefecture-level cities and counties in the country, and 5 million 6G mobile phone users.

"The capabilities and roles of 5G are currently more concentrated in the industry field, and are not fully reflected in the consumer application side." Wu Hequan, an academician of the Chinese Academy of Engineering, said at the 2023 China International Information and Communication Exhibition that 5G application solutions in key industries such as mining, ports, and power are extensive, but consumers' perception of 5G is not deep, and 5.5G may be the key to breaking the game, and it is expected that 2025.5G will be commercialized in 5.

Wang Tao, Executive Director of Huawei and Director of the ICT Infrastructure Business Management Committee, said that with the gradual improvement of standards, spectrum, industry chain, and ecosystem preparation, 5.5G will accelerate from consensus to reality. The improvement of the 5.5G <> Gigabit experience, combined with new capabilities such as perception and positioning, will push the traditional two-dimensional audiovisual experience to three-dimensional full-sensory interaction. The ability of synaesthesia fusion and the high-speed and stable satellite-ground integrated network will promote the intelligent network of automobiles; High reliability, low latency, and large uplink capabilities will promote the industry's transition from information silos to intelligent connectivity.

"The concept of 5.5G is not unusual, and there will be 5.7G, 5.8G, etc. in the future, just like 4.3G before the emergence of 9G." Xiang Ligang said that there is still a long way to go before 6G. At present, 6G is still in the early stage of vision demand formation and key technology research, "no matter what the concept is, it shows that there is still some distance from 6G."
