And the 5G network we're talking about today is theoretically 40 times faster than a 4G network.
Concretely speaking, we will use it to download a movie in a matter of seconds, maybe just pointing to save the download, and then the download will be completed with a "thud".
However, 5G is fast, but it's "awesome" in more ways than one, and low-latency and broadband are 5G's strengths, as well as the most essential difference between it and 4G.
The latency standard in the 4G era was 10 milliseconds, while 5G achieved 1 millisecond, or 0.001 seconds, not to mention that this subsecond gap is hard to detect in our daily lives.
But for our future technology outlook for artificial intelligence, drones, telemedicine and other areas of technology, it is the most important basic link, without which it may be "difficult to move".

For example, in the case of unmanned vehicles, given the fast-changing nature of the vehicle's travel time, if the traveling car is not able to provide timely feedback to the network processor, and the processor is not able to send the instructions back to the car in a timely manner, then the direct result is often a car crash.
It may also be for this reason that many companies have developed unmanned cars, but do not dare to commercialize them easily.
At speeds of up to 100 kilometers per hour, a subtle delay is often a human tragedy.

It can be seen that in the near future, because of the successful use of 5G, the global science and technology will once again embark on the rapid development of the highway, artificial intelligence, unmanned driving, remote medical science and technology scenarios, is no longer far away from our days.
And more fortunately, standing on the wind of 5G network, often satirized by the foreign media no happy technology of China miraculously ahead, breaking the U.S. monopoly on the rules of communication networks.
At 0:45 a.m. U.S. time on Nov. 17, 2016, in the discussion of 5G short code scheme in the 87th meeting of 3GPP RAN1, after a lot of painstaking efforts, China's Huawei's Polar Code (Polarization Code) scheme, finally overcame the powers that be, and became the final scheme of coding for the eMBB scenario of the 5G control channel.
Meanwhile, China does not dare to lag behind in 5G hardware, for example, in February 2017, ZTE released a full series of pre-commercial base stations for 5G and debuted Flexhual, a 5G bearer solution based on IP+Optical.
For the technological rise of Chinese companies, the country put forward the network rollout in 2019 and commercialization in 2020... ...timeline, which is far faster than the EU's 2020-2025 timeframe.
So based on the theory that whoever controls the network will control the future, the U.S. government is starting to get alarmed, the Committee on Foreign Investment in the United States (CFIUS) wrote bluntly in a letter to local companies.
"...... Considering the well-known national security concerns related to Huawei and other Chinese companies in the communications industry, China's dominance in the 5G space, if achieved, would have a significant negative impact on U.S. national security."
On April 16, the U.S. Department of Commerce announced that it was banning U.S. companies from selling electronic technology or communications components to ZTE for a period of seven years. Inferences based on the content of the previous letter.
Some media outlets now see this as the first shot in the arm for the US to take control of 5G networks in the future.
