Currently, Chinese operators have deployed 5G-A test networks in 31 provinces across the country. It is expected to support 50 million users. Meanwhile, it has also been verified in multiple regions such as Europe, Latin America and the Middle East.
Compared with 5G, the most intuitive experience of 5G-A is its "speed", which is 10 times faster all at once. The maximum data download rate of 5G-A will be increased from the initial gigabit speed of 5G to 10 gigabits, which can support the needs of large bandwidth, low latency and high reliability required by innovative services such as extended reality and naked-eye 3D. And the maximum data upload rate will also be increased from 100 megabits to 1 gigabit, which can support the comprehensive uploading of massive data to the cloud, the popularization of live streaming, and the symmetrical experience of holographic interaction, etc.
The team from the University of Science and Technology of China has, by "taking images" of light-emitting diodes (LEDs), identified the cause of the performance bottleneck of pure red perovskite LEDs, and successfully prepared high-performance pure red perovskite LEDs. The relevant research results were published online on the same day in the international academic journal Nature.
Metal halide perovskite is a new generation of star semiconductor materials. As a material for the light-emitting layer in LEDs, it has the advantages of high carrier mobility, high color purity, wide color gamut, etc.
Rockchip officially announced the launch of its new - generation AI vision chip RV1126B today. The chip has passed mass - production tests and will start mass - supply this month. RV1126B is equipped with a 4 - core A53 CPU and a 3TOPS NPU. It supports complex - scene recognition and cross - modal fusion. The AI - ISP technology enables ultra - high - definition image quality. The standby power consumption is as low as 1mW. It also features 8 - megapixel 45FPS encoding and a national - level security solution.
At the 2025 European Battery Energy Storage Exhibition held on May 7th, CATL launched the world's first 9MWh ultra large capacity energy storage system, TENER Stack.
According to CATL, TENER Stack adopts high - energy - density batteries and five - year - zero - decay technology. Compared with the traditional 20 - foot energy storage system, its volume utilization rate is increased by 45%, and the energy density is increased by 50%. It can charge 150 electric vehicles. In April last year, CATL launched the 20 - foot energy storage system TENER with a capacity of 6MWh, which can achieve zero decay of capacity and power in the first five years of the operation period.
The "YK - A2" drone countermeasure system developed by the Guangdong Academy of Aerospace Sciences has successfully passed the test. This test included subjects such as the interceptor hitting the hovering target and the net - capture of the moving target, comprehensively verifying and assessing key technologies such as the seeker's small target recognition, kinetic - energy - interception guidance law, flexible net - capture technology, and intelligent command and control system. During the test, the independently - developed "YK - A2" drone countermeasure system performed outstandingly, successfully achieving the precise recognition, real - time tracking, and hard - kill interception of moving drones. This marks a key breakthrough for the Guangdong Academy of Aerospace Sciences in the application of key technologies for the collision and net - capture of "low - slow - small" drones, laying a solid foundation for the industrialization of the "YK - A2" drone countermeasure system.
