5g has arrived the night before, an unprecedented wave of technology hit! If the long-standing 2G era opened the door of mobile Internet, then every upgrading of mobile communication technology has brought earth shaking changes to our lives. So how will 5g change our lives 2019? 5g's impact on life is overwhelming!
Written on the eve of 5g: what will interconnection bring us?
Recalling that wild 2G era, there is such a painting that I will never forget. A great God in the editorial department connected to GPRS mobile network through Nokia mobile phone, and opened the home page of ZOL, which instantly attracted the attention of colleagues.
When they stare directly at the page on the mobile screen, they look like the picture of children expecting mysterious gifts, which makes me most impressed by the 2G era.
2G era is of great significance for mobile Internet, but the memories are not all beautiful: GSM network dominates the world and the operator is the only one, which leads to high cost, weak network speed and poor signal & hellip & hellip; and the root of all this is the lack of full competition in the industry.
Until one day, Qualcomm with CDMA technology appeared in front of people, permanently changing the global wireless communication pattern.
In 1989, Qualcomm CDMA team rewrites the world communication pattern for the first time
I still vaguely remember that China Unicom, which operated CDMA network in those days, publicized it as follows: military technology, low radiation and no dropping words.
Perhaps these three key words can improve the pain point of mobile communication field at that time, but the GSM network pattern has been formed, and the CDMA technology dominant finally can only rely on the low tariff to capture part of the share.
In the 2G era, Qualcomm, with its CDMA technology, has entered the blue ocean of mobile communication, and laid the groundwork for the coming technological innovation.
When the "g" or "e" network logo on the top of the mobile phone becomes the past, and everyone is talking about the new term "3G", a revolution of the mobile Internet begins.
Due to the evolution of 3G network based on CDMA technology, Qualcomm, the leader of CDMA technology, has occupied the commanding height of the global mobile communication field in an instant, which verifies the strategic wisdom of Qualcomm in pushing CDMA Technology in that year, and also enables China Unicom, which embraces CDMA, to achieve a successful counter attack.
In the 3G era, the network speed of mobile phone has soared from tens of kilobytes to hundreds of kilobytes, instantly opening up the two channels of the mobile Internet.
Mobile phone is no longer a single communication tool, people use mobile phone to send wechat, microblog, and navigation, sharing, shopping applications based on location-based services are born, and mobile games are also in the boom stage.
3G network has completely changed the way of communication and leisure, but the explosive growth of mobile Internet application demand has exposed a new problem - the lack of experience.
Experience oriented Qualcomm snapdragon brings new inflection point for mobile Internet
The development of mobile phone chip has lagged far behind the outbreak of demand. The performance is low and it can't run large-scale 3D games, the power consumption is extremely high and the endurance is extremely worrying, and mobile phone warming hand treasure has become a helpless embarrassment.
At that time, people's cognition of chip brand still remained in the field of "lights, waiting lights, waiting lights", and the field of mobile phones was relatively vague.
Until the lovely "Xiaolong" image appeared frequently in front of the world, the high-performance and low-power famous gaotongxiaolong mobile platform solved the pain point of user experience, and brought a new turning point for the development of the entire mobile Internet application ecology.
3G era makes us embrace mobile Internet for the first time, while 4G ushers in a better era.
4G network speed has been greatly increased to the level of MB again. The high-performance and low-power mobile phone chip complements the short board at the experience level. The double leap of network and hardware has injected stronger entertainment attributes into the mobile Internet.
Whenever and wherever possible, a live broadcast of the tiktok and headlines on the subway will start with a chicken meal, which has become a portrayal of modern mobile internet life.
Looking back on the 30-year development of mobile field, we have completed the first transformation from mobile communication to mobile Internet, and the industrial pattern has also returned to the origin of paying attention to user experience from the struggle of building barriers.
Today, 4G is about to turn over in the history of human mobile Internet, 5g network will open a new chapter of the Internet of everything & hellip;
Along the way from 2G to 4G, calling and texting gradually evolved into wechat, microblog, live broadcast, small video and other diversified social ways. The Games in mobile phones have changed from greedy snake to 'pesticide' and 'chicken eating'.
With the continuous iteration from 2G to 4G, the way of people's communication and entertainment has been completely changed. In the next coming 5g era, a revolution in the interconnection of all things is about to start. Are you ready?
Oppo completes 5g signaling and data link connection test
On August 28, oppo completed the connection test of 5g signaling and data link. The oppo R15 mobile phone completed the test also uses the industry-leading Qualcomm snapdragon X50 5g modem solution.
As an important node of communication technology update, 5g will comprehensively improve the speed, stability, reliability and low latency of the network, and realize new experiences including 3D communication, 4K + Ultra HD video viewing, online AR / VR, cloud office, cloud game, etc.
Oppo realizes 5g connection based on LTE band 5 and 5g NR N78
The successful connection of the signaling and data link of oppo is based on 3GPP release 15 NSA standard, and adopts 10MHz bandwidth of 4G LTE band 5 and 20MHz bandwidth of 5g NR N78 band.
Among them, N78 band is one of the most widely used 5g NR bands in the world, and is also considered to be the most likely band to be deployed preferentially in the world, which is of great significance to the commercial use of the first batch of 5g products. The industrialization of 5g will usher in a comprehensive stage.
With the support of high bandwidth and low latency of 5g network, the traditional mobile phone performance may not be the key, because there are billions of computing supercomputers in the cloud at any time;
The super GPU in the cloud can provide us with PC level excellent image quality; the storage space in TB will completely solve the embarrassment of mobile phone capacity.
Mobile phones will interact with everything, houses, cars, or intelligent robots, all of which will be the same as local operations.
So it seems that the emergence of 5g network may be an important transformation of mobile phones. The trend change of application ecology also brings a positive change to the research and development direction of mobile phone chips. Simply improving the so-called performance can no longer adapt to the changes of 5g era in the future.
Therefore, we can see that several giants with the R & D strength of mobile phone chips, without exception, are extending the mobile phone chips in the direction of more intelligent and energy-saving.
7 nm Qualcomm snapdragon
On the evening of August 22, Qualcomm first announced that the Qualcomm snapdragon mobile platform with 7Nm process technology has begun to produce samples. In addition to the previously released Qualcomm X50 5g baseband, the industry believes that Qualcomm may build the world's first 5g mobile platform.
Due to the fact that this 7Nm process chip has not been officially released and the detailed parameters are not known, many conjectures are aroused.
The progress of semiconductor technology will be directly reflected in the improvement of performance and power consumption, and the smaller chip size can carry more functional modules.
At present, the active Qualcomm snapdragon 845 mobile platform has taken the first step of AI Artificial Intelligence and immersive experience. The new 7Nm Qualcomm snapdragon mobile platform may continue to strengthen in new fields. With the Dongfeng of 5g network, it is expected to become an important node to change the historical mission of mobile phones.
Mobile phones have the ability of local Ai Ai Ai computing, thus becoming a new smart entrance. 5g + cloud further expands the experience scene and application space of mobile phones.
The "two swords" Qualcomm mobile platform has successfully paved the runway for 5g network, and the new pattern of 5g era of "everything intelligent, everything connected" is launched.
AI technology is regarded as a great technological innovation. In short, its technological charm lies in its ability to give machines the ability to think like human beings.
The two technology bases of AI are computing and communication.
The world's leading technology companies are engaged in the research and development of artificial intelligence processors, so another "communication" bottom technology breakthrough will rely on 5g network.
Xiaolong 845 platform introduces a new architecture of AI and immersion experience
Just recently, at Chongqing smart Expo, Qualcomm once again showed us the broad application prospect of 5g network overlay artificial intelligence.
In the field of mobile phones, the Qualcomm snapdragon 845 mobile platform, which integrates the AI engine of Qualcomm's artificial intelligence engine, has been applied in many flagship mobile phones.
Artificial intelligence behind the dance
For example, the QQ high-energy dance room mobile phone application, which makes the whole people 'embarrassed to dance', seems to be a very happy game on the surface, but there are many innovations on the technical level.
In this application, the mobile phone completes the recognition and tracking of human movements, as well as the most difficult dance analysis.
With the help of the snapdragon neural processing engine (snpe) SDK, the mobile phone can handle AI computing locally.
Under the dual catalysis of artificial intelligence and 5g network, the Internet of things and robots will be the most direct beneficiaries.
The so-called Internet of things is to access 5g network under the premise of intelligent everything, so as to realize a broader application scenario.
In the subdivision of the Internet of things, the smart home is the one that has a more positive impact on our lives.
Qualcomm smart gateway technology layout smart home
The pain point of smart home lies in the wiring. Qualcomm smart gateway technology can realize wireless high-speed and intelligent connection, making it easier to build smart home system.
In the future 5g era of smart home application scenarios, all kinds of smart home appliances connect to the cloud through 5g network, not only free from wiring problems, but also based on users' habits, to create your own smart personal butler.
From point to area, 5g network connects every smart home again, so as to build a smart city in the future.
Robots will become killer applications in 5g Era
The future development path of robots may be very similar to that of mobile phones. Local hardware is responsible for Ai Ai Ai computing, and big data applications are connected to the cloud through 5g network.
It is reported that Qualcomm has a number of robot solutions, such as snapdragon cargo, snapdragon rover, etc.
If the existing robot scheme is given artificial intelligence technology and 5g network communication support, maybe the scene in the American drama "the western world" will appear in front of us.
Maybe one day you will find that the weather forecast is more and more accurate, the mobile navigation planning route is more and more intelligent, the urban traffic signal light will automatically adjust according to the traffic flow, more and more intelligent terminals appear on the street, and the little brother who delivers meals and express to you has become a robot, so maybe these changes are based on 5g Network + cloud + artificial intelligence.
The Internet of vehicles has become the development direction of global attention, and in this subdivision field of Internet of vehicles, 'intelligence' and 'security' will become two important main lines of development.
When it comes to the concept of the Internet of vehicles, we have to mention the c-v2x technology. V2x is vehicle to everything, that is, the interconnection of vehicles and everything. It aims to improve vehicle safety, automatic driving and traffic efficiency.
But without the support of 5g network, everything would be empty talk.
C-v2x technology passes 5g
