5G commercial has been 4 years, many people bought 5G mobile phones, paid 5G tariffs, seems not to find any interesting 5G new applications, is 5G just a continuation of 4G?
These people are also too anxious, and according to historical experience, network construction and the development of new applications usually promote each other. The 5G license was released in June 2019, and it has only been under construction for four years, and it is in the middle of construction, and many new businesses are being incubated.
Today, China has built 2.73 million 5G base stations, initially forming a scale effect, and a new wave of 5G applications led by leading enterprises such as China Mobile, BOE, Douyin, iQiyi, Cloud Vision Technology, and Zhenxiang Technology is finally coming!
1. 5G new calls
5G new call is a new mobile phone application that operators are vigorously promoting, which will become a built-in function of smart phones, no need to download APP and add friends, boot can be used, more intelligent, convenient and powerful than WeChat voice.
There are more than 27 million deaf and mute people on the mainland, who can use mobile phones to access the Internet, but they cannot make calls, and when they need to call 110 and 120 in an emergency, they will encounter great obstacles.
5G new calls have a "smart translation" function, after the call is connected, the hearing impaired's mobile phone will play an opening statement to the other party, introduce their situation, ask the other party to slow down when speaking, and wait patiently for a reply.
After the other party finishes speaking, the hearing impaired's mobile phone automatically converts the voice into text and displays it, and after replying with text, the other party's mobile phone is converted into voice and played.
Simply put, the hearing-impaired side is text communication, and the other side is voice communication, which solves the long-standing problem of telephone communication for hearing-impaired people.
It is more convenient to talk to foreigners, foreigners speak foreign languages, you hear Chinese, you respond with Chinese, the other party hears foreign languages, "chicken and duck speak" without obstacles.
I called my parents, and if they didn't answer, I would be very worried, afraid of an accident, rushed to visit, only to find that I just didn't hear it.
5G new call has a "multi-terminal call" function, parents do not answer the phone, I will call my parents' smart doorbell, smart door lock, smart camera, smart speaker, the TV will show my big face.
Once my mother told me that the screen of my phone became very dark and I couldn't see clearly. I called her to instruct her to adjust the brightness, and my mother was over 80 years old, and the more she listened, the more confused she became. I had to drop what I was doing, drive for half an hour, and adjust the brightness in 5 seconds.
The "remote assistance" function of 5G new calls perfectly solves this problem. When my mother's mobile phone encounters problems again, I will take over it remotely, and the screen of my mother's mobile phone is displayed on the mobile phone, and any of my operation settings will take effect on my mother's mobile phone.
Call the service agency, the most annoying thing is the cold voice prompt, A business please press 1, B business please press 2, after selecting manual customer service, a light music will be played, a minute later told "the artificial agent is all busy", continue to wait please press 1, cancel the service please hang up.
5G new call has the "intelligent customer service" function, artificial intelligence customer service answers the phone in seconds, she can fully understand your needs, provide the most intimate service.
Is artificial intelligence really so powerful? There is a reason for this, the scope of questions and answers for special services is very narrow, and the answer is also very clear, through big data training, the robot has long been familiar with all situations, and is more proficient than the real customer service who knows the business best.
2. Cloud mobile phone
Did you find out? In recent years, the pace of mobile phone replacement has slowed down. This is because the size, weight, and heat generation of mobile phones are strictly limited, and the improvement of chip capabilities is not endless, and the performance of mobile phones has reached the platform period.
Another new application of 5G, "cloud phone", opens up a new track to improve the performance of mobile phones.
The working principle of cloud mobile phone is to create a "new mobile phone" in the cloud, and put the storage, computing, rendering and various applications of the mobile phone in the cloud.
Every click or operation you click or operate on your mobile phone will be used as a control command, uploaded to the cloud in real time through the low-latency 5G network, and the cloud will transmit the calculation results back to your mobile phone through the 5G network after processing.
The performance of cloud mobile phones is no longer limited by the volume and weight of the mobile phone. If you want to improve performance, add more equipment, add a few more fans when the heat is large, and provide more performance if you want more performance.
Because the core processor is partitioned, the cloud phone will be lighter and cheaper, and the performance will be greatly improved, because it calls the capabilities of the cloud.
Why hasn't such a good idea been realized before? This is because the network delay before 4G is relatively high, you click on the mobile phone, the data is transmitted to the cloud, and then transmitted back after the calculation requires a large delay, the mobile phone will show a very lag, and the low latency of 5G ensures the agility of human-computer interaction.
A cloud mobile phone can set multiple numbers, work number, social account, shopping account, game number, and multiple accounts are online at the same time to avoid frequent switching. More importantly, cloud phones can achieve data isolation, and various social identities are independent of each other.
Mobile games are very demanding on mobile phone performance, and players have to spend more money on high-end machines. In the future, you can buy a cheap cloud mobile phone, computing and rendering are done in the cloud, and the problem of mobile phone heating and battery life is also solved at the same time.
In the future, when comparing mobile phones, it will not mention which chip is used, but which cloud is used, even the worst cloud, the ability is millions of times stronger than mobile phones.
Just like many people are used to cloud storage and give up active hard disks, once you use a cloud phone, you can never go back.
3. HD video and naked-eye 3D
There will also be a new application for 5G phones this year, that is, high-definition video, which will increase the resolution from 540p and 720p to 4k.
The phone screen is so small, do you really need 4K resolution? Many people underestimate the infinite pursuit of detail of the human eye. You may wish to recall that when the first version of "Journey to the West" and "Romance of the Three Kingdoms" first came out, the emotional picture was really clear at that time, can you still watch it now?
4K HD video will be available this year, and another new application, glasses-free 3D, is expected to be launched next year, eliminating the need to wear 3D glasses and forming a stereoscopic picture in front of the naked eye.
The technical level of naked-eye 3D has not yet reached the conditions for large-scale promotion, the picture quality is slightly rough, and the sense of light and shadow is too strong, this is just because the computing power is not strong enough, please do not doubt the speed of technological progress, it will be solved soon.
4. Holograms
At this year's International Information and Communication Exhibition, there were three large goldfish tanks at the entrance of Huawei's exhibition hall, and two dancers were dancing inside.
At first glance, I thought it was a real person, the green tendons on the back of the dancer's hands, the folds of his clothes, and the shadow of his dancing shoes on the ground, it couldn't be more real. This is a hologram based on 5G's ultra-large bandwidth, ultra-low latency and large computing power.
The technical route of holograms has been opened, and the reason why they have not yet been promoted is nothing more than cost-benefit considerations, and experts expect to be commercialized in 2025.
Now the first row of VIP tickets for the star concert is sky-high, and even money can't be grabbed, and when holograms enter ordinary homes, everyone can enjoy the audio-visual feast of VIP boxes, which is exciting to think about.
Some people always question what is the use of 5G's high speed and low latency? This is a consideration of 4G applications, and does not take into account the new 5G applications that consume more resources.
For glasses-free 3D and holograms, the existing 5G network resources are still insufficient, and operators are working hard to improve the capabilities of 5G networks and prepare network resources for the landing of new 5G applications.
These four new 5G applications are basic capabilities, on the basis of which there are countless new business opportunities, and the time has come for 5G to change society.
