China’s “New Four Great Inventions”: mobile payment, high-speed rail, shared bicycles, and online shopping have already become hot topics of international interest, making many foreign netizens envious and eager to bring these “New Four Great Inventions” back home.
Recently, a piece of news about high-speed rail has made many netizens ecstatic!
China is about to achieve this technology: free high-speed Wi-Fi on high-speed trains!
Yoyo forgot to bring a wallet? No problem with mobile payment!
Don’t want to squeeze into the subway? I’ll ride a shared bicycle!
On a business trip by train? High-speed rail has replaced slow trains!
No time to shop? Online shopping is the secret!
Recently, a freestyle about China’s “New Four Great Inventions” has gone viral across the country, receiving likes from netizens worldwide.
High-speed rail has always been known for its speed, safety, and smoothness, even offering food delivery services, but the network speed on high-speed trains has always been an area passengers wanted to improve.
On August 4, ultra-high-speed wireless communication (EUHT) technology was demonstrated for the first time on the Beijing-Tianjin intercity high-speed rail. At a speed of 300 kilometers per hour, passengers can enjoy very smooth real-time video through wireless Wi-Fi, with an average transmission rate about ten times that of existing 4G.
The issues troubling high-speed rail passengers have been resolved!

At the testing site of the ultra-high-speed wireless communication system (EUHT), passengers connected their phones to designated Wi-Fi, allowing stable and smooth internet access and video streaming, with an experience almost indistinguishable from home Wi-Fi.
How should we understand the application of ultra-high-speed wireless communication (EUHT) technology on high-speed trains?
The application of ultra-high-speed wireless communication (EUHT) technology on high-speed trains means that under high-speed movement at 300 kilometers per hour:
Communication handover reliability reaches 100%,
Average communication delay is 5ms,
Air interface delay is less than 1ms,
Average transmission bandwidth reaches 150Mbps.
If these numbers are unclear, the author tells you that these technical indicators exceed the current world’s most advanced 4G mobile communication technology by more than ten times and meet the performance requirements proposed for 5G technology.
This means you can do this on high-speed trains
And you can do this
Even this is possible
It is reported that this high-speed, free, and stable high-speed rail Wi-Fi is expected to be promoted first on the Beijing-Tianjin intercity high-speed rail by the end of this year, with plans to expand to other high-speed rail lines in the future.
We have finally waited for this day!~
