工业和信息化部负责人在上海举行的中国5G发展大会上透露,我国已提前完成“十四五”5G建设发展目标。


张云明表示,5G网络已全面覆盖政务中心、文旅景区、交通干线等重点热点场所,并不断向农村边远地区拓展深化。我国5G技术产业已构筑起涵盖通信芯片、终端、基站设备、设施仪表的完整产业链,共有近2000款5G终端产品上市商用。

工业和信息化部已举办七届5G应用征集大赛,应用案例超过10万个,5G应用已经融入97个国民经济大类中的80个。全球移动通信系统协会(GSMA)报告显示,2023年中国以5G为代表的移动生态系统创造了约800万个就业岗位。


工业和信息化部负责人在会上还表示要有序推进5G向5G-A升级,加强核心技术攻关,持续开展5G-A技术研究、标准研制和产品研发。

5G-A又称5.5G,是5G向6G发展的演进技术。相对于5G,具备更高速率、更大连接、更低时延等特点。通过引入通感一体、人工智能等技术,能更好地匹配车联网、高端制造、全场景感知等应用。目前,我国5G应用发展已取得阶段性成效, 5G正在向5G-A升级演进。工业和信息化部等部门近期联合发布的《5G规模化应用“扬帆”行动升级方案》中多次提到5G-A。5G推进组负责人表示目前正在推进5G-A 与人工智能、低空经济以及节能减排等领域的融合应用测试。


目前,电信运营商已经在全国范围内开始布局5G-A网络。中国移动的5G-A商用城市已超过300个;中国电信已在上海、广东深圳发布了5G-A套餐;中国联通已在广东佛山建成空域连续覆盖的5G-A试点网络。

Converting "gutter oil" to aviation biofuel:

using technology developed by Hangzhou Energy & Engineering Technology Co., Ltd. to clean contaminants from waste oils and convert it into jet fuel at a rate of 650 liters (160 gallons) per day, according to a statement from Boeing.

The two companies estimate that 1.8 billion liters of biofuel could be made annually from used cooking oil in China.

1.8 billion liters of aviation biofuel is equivalent to about 1.4 million tons. The initial annual production rate will be 50,000 tons.
The raw material for the project will be waste cooking oil. In China it is called gutter oil, and more than 9 million metric tons of it is discarded annually, said Zhu Cuihan, chairman of Hangzhou Energy and Engineering Technology Co Ltd, which is responsible for the technology research and development for the project.

"About 7 million tons of the waste oil has the potential to be converted into aviation biofuel," Zhu said. The company has forecast annual production of 50,000 tons, after technological improvements are made.

I still can't believe this is real. I would have never guessed that this would come out of it.

They should reward individual households for used cooking oil like a return recycling fee.

latest phone activation figures out of China including the past week.

Nuawei has now soared to top spot with 25% share since the M70 introduction. Up to 17.56% in Q4 now.
Behind just Xiaomi at 17.69% for Q4.

Apple was down to 12.2% this week and 17.39% in Q4.

Q4 is normally Apple's top quarter, so this is a disastrous trend for them in China.

Yet Apple stock price hits all time high…
