5G network allows for telemedicine in China’s countryside

The first ambulance equipped with 5G telecommunications was put into operation to supply villages that were difficult to reach. China Mobile, together with the University Hospital of Tongji University and Huazhong University of Science and Technology, has developed an ambulance equipped with a 5G mobile network and augmented reality modules for remote diagnosis. In the vehicle there is a small team of doctors operating the diagnostic equipment. The data is transmitted via the cloud to a specialist in a municipal hospital, who makes the diagnoses and decides whether the patient has to go to the hospital or can be treated on site. In a first village, dozens of people have already been examined for eye diseases, and doctors from Tongji University Hospital diagnosed patients 400 km away live via a 5G network. The project is part of the Precise Poverty Reduction Strategy of Hubei Province. Xinhua news, July 30, 2019

91% of China’s cities communicate on optical fiber systems, and 4G penetration rate of households is 77.6%

According to a review at a national telecommunication symposium held on August 1 in Dunhuang, Jiuquan, Gansu Province, the optical fiber network penetration in Chinese cities has reached 91%, with 100 MB/sec as the main choice for broadband users. In administrational villages, penetration rate exceeded 98%. The number of 4G base stations reached 44.4 million, and the 4G penetration rate 77.6%. In recent years, China’s fixed broadband household and mobile broadband user penetration rate have significantly improved, the former to 89%, the latter to 96%.

“Solar farming” in Fujian province

Modern solar farming has been established in Dongping Town, Fujian province. The area of the project is approximately 133.3 hectares, integrating photovoltaic electricity generation, agricultural production and touristic services. The annual power generation is about 90 million kWh, and the power is incorporated into the national grid. Farmers in mountainous areas thus develop new means of prosperity.

Tsinghua University develops novel chip architecture for general artificial intelligence

The chip is based on a hybrid architecture combining a many-core architecture, reconfigurable building blocks and a streamlined dataflow with hybrid coding schemes. It can not only accommodate computer-science-based machine-learning algorithms, but also easily implement brain-inspired circuits and several coding schemes. Using just one chip, the team around Luping SHI demonstrated the simultaneous processing of versatile algorithms and models in an unmanned bicycle system, realizing real-time object detection, tracking, voice control, obstacle avoidance and balance control.  Nature 572, pages106–111 (2019) 

China promotes the development of fuel cell cars

After a visit of China’s Prime Minister LI Keqiang to Japan, the development of hydrogen-based fuel cell cars in China gains momentum. The official development plan now provides for 50,000 vehicles by 2025, and car manufacturers such as BAIC, SAIC, Great Wall Motors and Dongfeng are now involved in the development of hydrogen-powered passenger cars, partially based on free licenses from Toyota, which put this development on the road in 2014 with the Toyota Mirai. The necessary infrastructure for hydrogen production and refuelling is to be created within the framework of a China Hydrogen Fuel Cell Alliance 中国氢燃料电池联盟, and between 2019 and 2021 more than 40 hydrogen refuelling stations are to be set up in the Yangtze Delta around Shanghai alone. Two excellent reviews by JETRO (in Japanese) and by Elektroauto News (in German) cover the outlook for the coming years.
