5G standard released, what is the difference with 4G? Or download 1G movie in 1 second

[[233400]]

Key Points

1. China Telecom conducted a 5G pilot field test in Xiongan New Area at the end of last year. Compared with the current peak experience of 4G users, 5G can improve it by about 20 times.
2. Since the latency of 5G networks has also been reduced from 30-50 milliseconds in 4G to 1 millisecond, the response speed has been increased and driverless cars will be safer.
3. The Ministry of Industry and Information Technology has repeatedly stated that 5G is expected to be pre-commercialized in China in 2019 and officially commercialized in 2020.

What is 5G?

"My mobile phone has 64G, what's the big deal about 5G?" said one netizen.

This 5G is not that 5G.

According to technical experts, 5G is the fifth generation of mobile phone communication standard, also known as the fifth generation mobile communication technology.

On June 14th, Beijing time, 3GPP (3rd Generation Partnership Project) held a plenary meeting in the United States and approved the freezing of the independent networking function of the fifth-generation mobile communication technology standard (5GNR, NewRadio).

Together with the completion of the non-independent networking NR standard in December last year, 5G has completed the first phase of full-function standardization, which means that 5G has entered a new stage of full industry sprint and mobile communications will usher in a new era of full connectivity.

"It sounds so profound, but I have no idea what you are talking about. Can you explain it in more simple terms?" said a netizen.

Let’s first take a look at what 5G can do?

The first is high speed.

According to the operator, it takes an estimated 30 seconds to download a 1G movie on a 4G network. If a 5G network is used, the calculation unit may not be seconds.

A professional interviewed by Chinese media said that the speed of 5G is 100 times that of 4G, and foreign media reported that the speed of 5G will be tens of thousands times that of 4G. By then, watching videos and playing games on mobile phones will no longer experience "stuck" problems.

At present, the actual data that can be seen is that China Telecom conducted a 5G pilot field test in Xiongan New Area at the end of last year. Compared with the current peak experience of 4G users, 5G can improve by about 20 times.

Another feature of 5G is low latency.

Many applications will have substantial breakthroughs due to 5G. Taking the currently popular autonomous driving as an example, many teams told Chinanews.com that the speed during testing will basically not exceed 60km/h.

"Why? If the speed is too fast, the self-driving car may have 'kissed' other cars during the time from issuing the command to the time the car receives the command." said a member of the self-driving team.

But with 5G, these problems may all disappear. Since the latency of 5G network is also reduced from 30-50 milliseconds of 4G to 1 millisecond, the response speed is faster, and driverless cars will be safer.

"5G can be used not only to improve the quality of voice and video communications, but also to enhance a variety of new services such as IoT (Internet of Things) and autonomous driving, which fundamentally contribute to solving social problems," said Yoshiyuki Miyabe, senior executive officer and CTO of Panasonic Corporation.

The applications of 5G are far more than these, such as 8K applications.

"By using the 5G standard, Sharp will accelerate technological innovations such as '8K' (ultra-high definition images)," said the senior vice president of Sharp's mobile communications division.

It is understood that the resolution of 8K is 7680 × 4320 pixels, but in fact, 4K (resolution 4096 × 2160 pixels) is less used at present, and many so-called 4K TVs are "pseudo 4K". In addition, if you buy a 4K TV, you must have 4K resources. Sorry, there are none or very few.

Take online video platforms such as Youku Tudou and iQiyi as an example. 720P resources are one level higher than "HD". 1080P (1920×1080) requires paying for membership. If 8K technology really breaks through and film and television resources are truly available to the public, it would be so exciting.

So for 8K, hehe, just wait with a "normal mind".

In addition to these applications, 5G has some new labels. The reporter noticed that compared with previous generations of mobile communication technologies, "flexible" is the first new label attached to 5G.

Arnaud Vamparys, SVP of Orange Wireless Networks, said: "The success of the new 5G standard provides more flexibility for future 5G applications and enables automatic deployment of 5G in accordance with national policies, regulations and national conditions."

Masahiro Inagaki, senior executive officer and general manager of Kyocera's R&D division, said: "Kyocera believes that this new technology will fundamentally improve network resource utilization efficiency and deployment flexibility to support a wide range of applications with different QoS requirements, including IoT, V2X and other applications that require high efficiency, high reliability and low latency."

IoT refers to the Internet of Things, and V2X refers to vehicle-to-vehicle information exchange.

In addition, Neil J. McRae, chief architect of British Telecom (BT), said, "This step (the release of 5G standards) lays a solid foundation for 5G to achieve low latency, large connections and high reliability."

Did you see that? High reliability, massive connectivity. Junichi Miyakawa, legal representative and chief technology officer of SoftBank, said: By 2020, everything will be connected to the Internet.

"Wow! 5G is so powerful. According to what you said, I feel that 5G is coming soon. Should I save money to buy a 5G mobile phone?" asked a netizen.

Saving money is right, but if you want to buy a 5G phone, you have to have one. According to Shi Yujian, senior vice president and chief technology officer of vivo, vivo is stepping up the research and development of 5G phones and strives to launch a 5G phone that supports independent networking in 2019.

This means that 5G mobile phones are expected to be available next year. In addition to vivo, OPPO, Huawei, etc., have all said they will launch 5G mobile phones in 2019.

Mobile phone chip manufacturers have begun to prepare. MediaTek senior vice president Zhuang Chengde said: "With the full completion of 5G independent networking and non-independent networking standards, our 5G commercial chip development is gradually maturing."

But even if you buy a 5G phone as soon as possible, you may not be able to use the 5G network immediately because you still have to wait for the government to issue a 5G commercial license.

So, for those who are eager to change to 5G mobile phones, I would like to give you two words: "hold on." This sentence will still be valid until the end of next year.

Because, the Ministry of Industry and Information Technology has repeatedly stated that 5G is expected to be pre-commercialized in China in 2019 and officially commercialized in 2020. The three major operators have also stated that they will carry out 5G pilot tests in 2018, plan to carry out trial commercial deployment in 2019, and realize large-scale commercial use around 2020.

"When 5G comes, will my 4G phone still work?"

It must be usable. At present, although more and more users are using 4G, 4G, 3G and even 2G networks coexist; similarly, after 5G is commercially available, 4G networks will not be shut down all at once.

"Then I'd better not use it. I think 5G phones will be very expensive at the beginning."

From historical experience, it is definitely expensive, but if you don’t use 5G, you will miss a lot of exciting things. Just as in the 4G era, new things such as mobile live broadcast, online car-hailing, and shared bicycles were born and thrived, the 5G era will also give birth to many things you can’t imagine, affecting the current business landscape and people’s lives.

Lenovo Group Senior Vice President and Chief Technology Officer Rui Yong may also be right when he said: "5G will change the rules of the game."
