So far, 5G network imaginary scenarios, most can be achieved through 4G, 5G yet to find their own scenarios.
However, perhaps there is one exception: mobile phone, computer and other local terminal transformed into a "cloud computer" screen, all operations and stored procedures are done in the cloud, thus eliminating the need to constantly upgrade equipment trouble. To get low enough latency, so that "cloud computer" and local computer as fast, perhaps only 5G can help us do it.
5G is envisaged scenarios of embarrassment
5G already on the way. With the laying of the metropolitan network expansion, and increase the number of terminals compatible, next year or two there will be a lot of people are said to spend the 4G 10 times faster than the technology. In fact, do not say how much faster times, just really in place to ensure that the signal, just like fixed-line broadband mobile Internet as fast as stable, even as long as no longer even micro-channel video "card", which is already a huge leap .
Depending on the configuration of your home computer, it is possible to download a large movie full grid with broadband speed, almost collected from mobile hard disk or U disk copy. The home router configuration is uneven, and sometimes let the two terminals connected LAN at home, do not speed, respectively, as the external network and then connected to each other.
From this we have to understand such a basic fact: the network speed to reach the final in front of you, in addition to the factors affecting the source of the transmission network, etc., of your own home gateways, terminals will affect. To the residential building water towers are output surging water, but tap your home is thin small pipe, and that there is no way.
For popular 5G will begin, there are a lot of people to carry out the fanciful to imagine scenarios, such as the most popular is the VR / AR, a variety of terminal performance but wearing glasses or helmet are unsatisfactory, the various R's "first year "I cried for a long time and have not seen really caught on.
Another popular argument is that 4K / 8K ultra high definition video to be popular, but think about it a little know the phone screen is not so much the point of consumption required ultra high-definition video on the move; As was quite improved from a production point of view. If the speed is fast enough, really easy after cell phone camera without compression, uploading video files from the original size. This is the future of local storage and cloud storage capacity of mobile phones need to purchase have raised new challenges.
There is a saying that due to the low latency, can be remotely operated robot, truly remote surgery. Unfortunately, this is not the first 5G era. As early as the summer of 2016, Mobile Asia Congress held in Shanghai on, I saw the booth Ericsson, Huawei and other manufacturers, has been playing table tennis robot drawing of what the.
Nokia Bell Labs senior researcher Professor Cai Yi Gang said that the number of public "cloud pond Academy", now these scenarios propaganda, most can be achieved through 4G, 5G only higher technical indicators have yet to find application scenarios. He is directed at "reports of domestic 5G of the vast majority are false."
International Telecommunication Union put forward a vision of 5G three major scenarios: Enhanced mobile broadband, large-scale machine-type communications and ultra-reliable low-latency communications. Professor Cai believes that the current 5G are enhanced mobile broadband, has not not do before 4G, 5G thing to suddenly be able to do.
Google Stadia heralded "cloud computer" vision
- maybe, with one exception. This is to make computing unit mobile phones, computers and other equipment to move to the cloud, so that they become a "cloud computer" a screen, thus eliminating the need to constantly upgrade the renewal of trouble. This is also true of the previous network conditions can not be done.
According to Lei Feng carded web, cloud gaming industry recognized the birth of the earliest in 2009, but could not widespread. Cloud games no 5G is not no, but there 5G mobile terminal to achieve greater bandwidth, lower latency. 4G era mainly by optical fiber to cloud the game, but as a parallel rapid development of Chinese mobile games and end the tour as hand travel is a much broader market.
Google chose to launch this cloud gaming platform Stadia, more radical solutions than the previous Microsoft Xbox streaming service. The company said, Stadia on the basis of network infrastructure, hardware, compression and coding, and transmission from the data center to the players the way home, etc., carried out about 100 kinds of innovation, so streaming speed is not a problem, more than the reaction of the human body and processing speed information.
Maybe Google a few years ago with the technical conditions within the stream of well-LAN environment, but everyone can get the same rate through external network links, is really only 5G network can do.
Since even the streaming game speeds are available, so just do productive work, or video clips, render 3D scenes, and so, naturally mention. Install the operating system in a cloud environment, you may have to pay with cloud storage space, you do not need a backpack, wherever your "computer" where you can talk to.
Moreover, since the local terminal only uses a keyboard, mouse and other input devices such as displays and output devices, then regardless of their original computing power, feel the connection is as fast; or, even office computers or Internet cafes , the connection can ensure that their desktop and file, when some of the information security risks can be solved.
In fact, such a scenario as early as the end of the 1990s, there is Microsoft, Apple, AT & T and other companies with a sci-fi first to predict the video mentioned. At that time I predicted the movie did not think VR / AR and huge, ubiquitous screen, just think of the desktop if you go to school or stay at the hotel, you can log in to your home out on the monitor, keyboard and mouse combination.
As the younger generation, we can only be ashamed to admit that at best can only do now access documents in the cloud network disk, watch movies or something. We still need a local machine, operating system and with local storage space, but also hesitant to log personal account on a public computer.
Does someone with such tools Team Viewer directly connected to the home in the remote desktop, but this requires home computer always on, but also need to have enough outside the home and high-speed networks while the terrible delay has become a nightmare for the operator. In addition, you can also access the large software within the browser, such as by Uzer.me and BrowserStack like this, really close to what I call "cloud desktop" mode, but its low efficiency and frequent dropped it quite touching.
If 5G can really achieve, and even surpass local operations and local area network connections, display rate, delayed or dropped completely solve the problem, then the emergence of a completely cloud Remote Desktop, you then to use it as a local computer, chances are you really not a fantasy.
Bitter farewell upgrade, with the "Configuration" to say goodbye
Counting from the birth of the first generation iPhone, the smart phone era has been 12 years, during which there was a tablet, Combo and other new styles, and traditional notebook form together comprise multiple mobile terminals that they had to distinguish between screen size and shape but limit each other more and more blurred.
Today, the mobile phone industry has undergone many changes, Apple's long-term dominance challenged, new manufacturers more choices. But did not change is that people are constantly replaced with new terminal, a larger storage space and longer battery life, faster processor and the periodic payment of tradition.
Accordingly, the price of the device after a short few years ago has fallen sharply, rose again to a relatively high level. Because mobile applications and features continue devouring the full potential of the hardware configuration, the new phones a year or two it will "change cards" laptop is difficult to obtain "frivolous" and "performance" of co-existence, even among some industrial design boutique, but also because of outdated and had to reluctantly part.
If possible, I would like to pick up the ThinkPad 701c IBM era of "butterfly machine", the Toshiba Libretto, Sony VAIOP such "pockets of this," but they can only run when the operating system Windows 95 and XP These are stumbling, and there is nothing headroom.
Others even contemporary products, but also because of software problems and reduced availability. For example, I have been dreaming of iPadPro smooth as a mirror can run macOS or other desktop systems, iOS a great waste of high-speed chip AI on a good touch screen and embedded piece. - not just one person I think so.
Imagine that you can dig out from a storage room that stage yet how used "lamp" computer iMacG4, open Windows10 on her petite 15-inch screen; or may accept only sell hundreds of dollars in free fish. " Village board "to make it back to life. Imagine that mobile phone manufacturers can no longer do differential pricing with storage space 32G-256G will not allow you to put in other configuration without changing the picture dig money wasted - and so on, then there are "Configuration" With that said it?
Even more exciting than all of this is, do not worry because the configuration obsolete and had to throw away old mobile computer, the future is likely to avoid a large number of e-waste, protect our fragile environment.
The latest United Nations report said in 2018, e-waste worldwide total of 48.5 million tons, the equivalent of all commercial aircraft manufacturing human so far the weight of aggregate. Now according to this rate, by 2050, the total amount of e-waste per year worldwide will reach 120 million tons.
By measuring the value of these discarded electronic products, an amount equal to the value of annual gross domestic product of Croatia, Costa Rica or Tanzania. These e-waste into the recycling of only 20%.
Whether it should retain the local computing and storage?
Of course, things are not so perfect as described above. Experienced the painful memories are not reliable network brings, it is difficult to relax and give up local storage space and computing power, everything that contains the operating system, including the hand over all cloud service providers.
On the other hand, as noted above, the longer the chain of transmission, in which data may be attenuated and the greater the chance of problems arising, micro-channel video even if the city perhaps better, not necessarily cross-Shun Liu, once the other side into the subway or elevator that would be a high probability break.
So, even the most aggressive promoter of the cloud system is probably also want some of the alternatives. As sales decline, in turn, carry the banner of privacy apples, then further relies on the internal computing power of the machine, but also on mobile phones, tablet inside the most precious A-series chips make the best use.
The introduction of news, movies and other subscription services on Apple's spring conference at the same time, Apple's emphasis on personalized recommendations for content is carried out by the machine operator, user preferences will not be uploaded to the Apple server, then caused a lot of viewers a surprise call.
In 2014, during my interview with the fixed point Science and Technology co-founder of the US semiconductor company happy (Marvell) of Dai Weili. Because the operating environment in the cloud hosting is a long time since I have an idea, when I asked her such a future will appear: "...... capability will not be local computing and storage is no longer important, slowly ? will disappear, "she replied:
"I agree that there will be more and more functions will be moved to the cloud, but not rely on a cloud, or remote-called data processing center will be able to solve all the problems. In fact, the cloud can be divided into many many layers, such as mobile cloud , enterprise cloud, in a small business can have the same virtual computing center. there are car cloud, all kinds of files to be backed up in the car, but it can get real-time information to ensure safe driving. All of these are relative. cloud more and more important, but the whole process of calculating and collecting data, will be assigned to different so-called cloud go inside. "
It now appears, wearing remarks, happens to be on the "edge computing" concept formed a year is not too popular explanation.
March 8 this year, I attended an event organized by the olfactory tiger, it was invited Ali cloud computing technical director Yang Jingyu edge to edge computing concept simply speaking. Wherein he talked about different types of data collection, calculation of how reasonably assigned to the cloud, to the end and edge processing.
He mentioned that "brain city" is the use of cameras, sensors, networking equipment improvement projects of urban governance. Hangzhou to the transportation system, for example, when a large number of camera access networks, each with real time live images of high bit rate, is not suitable for all incoming instant center cloud. Preferably at a location on the street, the machine arrangement, to complete some pre-structure calculation on the raw data.
He believes that when the delay is reduced to a certain extent in the future, count on the power of cloud will become possible. But if everything on the cloud center, might be slightly slower pace, even until 6G 7G, that the same effect is calculated by matching the edges, it is possible to be able to achieve the 5G environment. For example, a school room without having to purchase a large number of desktops without replacement, can demand the opening of the machine in the cloud - which happens to have been conceived with my "cloud computer" coincide.
I think that with the arrival of the times 5G edge computing concept, does give've seen clouds add a valid count on help force dawn. Allows hands no CPU, no screen computing power, can be close anchored in place to light up the edge server, start your job, just like holding a cell phone to find WiFi almost.
It may help us know sometime in the future, to achieve an earlier prophecy. I first saw in 1998, referred to at the time of futurology best-selling book "Learning Revolution" in:
"World Wide Web founder Tim Berners-Lee (TimBemers-Lee) said the new 'information application device' even appear in cereal boxes, he said: 'My child will be as usual in the box where to find prizes, pulled out a tube of the stuff, it will be rolled out to a flat, flexible and there is something magnetic, posted on the refrigerator and began to roam the World Wide web. ' "
