The advent of the 5g era
The advent of the 5g era, the 5G era we have a smart way, will change our life, business and the way we work, 5G is not only the ordinary sense of the network speed increase, but also a major significance of human progress, so together to see the advent of the 5g era.
The advent of the 5G era 1The current communication network is focused on cell phones, PCs and other terminals, the future of the chip with the device, more and more devices will be networked, and 5G as if the water pipe will be interconnected resources, if there is not a thick enough and far enough to enrich the water pipe, any more devices will be lifeless, the Internet of Things can not be talked about. At that time, 5G is like today's water, electricity, such as now hot and heavy cloud computing, big data, the same as the real meaning of infrastructure.
The 5G era will be the era of true realization of intelligence, where everything can be discovered and perceived through the network. Qualcomm is not a network mover, but will continue to play that "connector" role. In addition to the familiar smart phones, tablet PCs and other consumer electronics, Qualcomm will 5G tentacles to have connected to the cellular network needs of many industry sectors, such as automotive, wearable devices, cloud computing, smart homes, remote health care and other "massive Internet of Things", which is what we have been talking about This is what we have been calling the "Internet of Everything".
In fact, there is no need to be upset because of the high cost or to question, think about a decade ago, the home with a telephone dial-up Internet access, the monthly phone bill of more than 100, but we are still excited about the humble web page, who would have thought that today's network world is so colorful? When Bill Gates predicted in 1981 that 640KB of memory would be enough for any user, he would never have imagined that there would be more than 10G of memory at any one time. 5G is the same, but 5G is very special because it is different from the upgrade from 3G to 4G, and it carries the mission of revolutionizing more industries.
A new communications paradigm
As a result, there is a need for a complete overhaul of the network architecture from a cloud-based system to a distributed edge network architecture, or "edge computing".
5G will enable edge computing, which will be at the heart of the Internet of Things.
In its annual mobility report, Ericsson noted that by 2020, 5G mobile network subscribers will account for 15 percent of the global population, and 5G will connect everything from smart appliances to smart city solutions.
U.S. communications operators have keenly captured this opportunity and have increased their investments in 5G edge computing. Last year, AT&T joined forces with Ericsson, Intel, and conducted the first professional 5G trial. Last month, the three companies carried out a second test, through the 5G network for live pay TV programs, its network speed reached 1 gigabit per second!
It is reported that China will launch the second phase of 5G testing in 2017, and is expected to be completed by the end of that year. China Mobile and China Telecom revealed that after completing the second phase of testing, they will conduct large-scale test networks in 2018. After the relevant international organizations announce the official 5G standard, it will enter the network construction stage, and the 5G network will be officially commercialized in 2020 at the earliest. If the work progresses smoothly, the three major operators are expected to start 5G network construction in 2019, the total scale of network construction will be comparable to the scale of the existing 4G network, and the overall investment is expected to exceed 500 billion yuan.
By the time the 5G network is developed to a sufficiently mature stage, the "smart city" such as the dream of the city, will certainly be able to realize, and wait and see!
The advent of the 5G era2
We are now in a 4G into the 5G era, a transition period, in fact, after the launch of the 5G industry has begun to adjust their own strategic development, 5G era should be more rapid development of high-tech society.
Previously, there are many people have raised questions, 5G has long been introduced, when will it be popularized? It is all verbalized that 5G smart life, but the reality is still 4G operation. Huawei founder Ren Zhengfei once said: 5G popularization of the full implementation will take about 7 years to fully implement, just like the 4G era, is the need for time to precipitate and transition. If you imagine, in most of the industry above have not yet been able to realize the development of 5G, the general public of commercial 5G is also rhetoric.
So the era of 5G has not matured, in the digitalization of the present, 5G led only part of the industry and enterprises at the forefront, as the Internet under the high-speed operation of the enterprise is even more indispensable to the technology of 5G, then this group of enterprises will be the vanguard of the course of the 5G digitization of the enterprise mode and work will undoubtedly bring only more efficient work and more advanced
5G digitalization of business models and work will undoubtedly bring only more efficient work and more advanced technology.
The biggest carrier of 5G is the communication network, these will come from the mobile, Unicom, telecom network full 5G in order to full coverage. Mobile communications as to meet the needs of people's daily lives, but also in the work of the additional embodiment. Then as people can not be separated from the operator, in the process of changing times and fierce competition, more and more into a pro-people and people-friendly mode of operation. Network operation network speed increase, package selection preferential multiple constantly to create any kind of group package as the operating guidelines, from the mobile smart life.
5G also spawned more artificial intelligence industry, in the 5G Internet so that people's lives can be more and more intelligent, enhance the sense of happiness. Just like the full popularity of whole-house intelligence, from enterprise companies to the family from the outside to the inside, whether it is artificial intelligence or Ai, are bringing convenience to the public`s life, 5G is also bound to move towards the era of full popularization of artificial intelligence.
The advent of the 5G era3
Literally, 5G means "fifth-generation mobile communications technology".
With each generation of mobile communications, there is a big leap in technology. In the 1980s and 1990s, the brick-like "big brother" used the first generation of mobile communications technology, which can only transmit voice, that is, only call, not the Internet and texting, and voice quality is low, the signal is unstable, the coverage is not wide enough, and it is easy to be serialized and number theft.
From the second generation, that is, 2G, mobile communications began to enter the digital era, the quality of communication, security and speed have been greatly improved, the phone can be relatively low speed Internet access. 3G after the arrival of the Internet, due to the substantial increase in Internet access speed, mobile communications into the era of multimedia, we can send and receive cell phone images, music, smaller video, etc., but also can browse the web, hold teleconferences.
At the same time, we can use our phones to send and receive images, music, and smaller videos, as well as to browse the web and hold conference calls.
And with 4G, watching movies, sending videos, and playing games whenever we want is no longer a luxury. In the 4G era, we often use the software of jittery, fast hand, watermelon video, and the number of people playing games with cell phones connected to the Internet has exceeded the number of computers for the first time, and mobile payment has begun to replace cash, so that we can enjoy great convenience.
If the first four generations of mobile communication technology is relying on cell phone applications in the promotion, then the fifth generation is combined with the current trend of the Internet of Everything, to meet the needs of the Internet of Things, the Internet of Cars, intelligent health care, virtual reality, industry 4.0 and other applications. Therefore, 5G is not simply to improve Internet speed compared to 4G, but to take into account a number of technical indicators: network speed, mobility, latency, connection density and so on.
What does this mean? Network speed is easy to understand, so let's talk about the meaning of the other indicators.
Mobility:This refers to the ability to maintain transmission quality while in rapid motion. For example, high-speed trains now run at a maximum speed of 350 kilometers per hour, and will continue to do so. 5G mobility should address both the need to not be disconnected while watching HD movies on a high-speed train, but also the need to support speeds of up to 500 companies moving per hour.
Latency: is the time difference from one end to the other when transmitting data. 5G can provide latency as low as 1 millisecond, or one-thousandth of a second, which is 1/10th of that of 4G, and is perfectly suited to meet the needs of industries such as Telematics, Industrial Controls, and Remote Healthcare.
Connection density: refers to the number of various terminal devices that can be connected to the same area, while also meeting the requirements of low cost and low power consumption, which is mainly oriented to the Internet of Things and smart city type of applications. Therefore, 5G should not only focus on people's demand for network connectivity, but also promote a variety of sensory devices as well as vehicles of the Internet of Everything.
The popularization and continuous upgrading of 5G will greatly expand the scope of applications of mobile communications, making our production and life more beautiful and convenient.
How fast can 5G download a high-definition movie
As we know, it usually takes more than ten minutes for an ordinary home broadband network to download a high-definition movie, such as Harry Potter and the Sorcerer's Stone, at present. Even at the fastest speeds claimed by the telcos, it takes 2 minutes to download successfully. What if you use a 4G network? The fastest download speed also takes 4 minutes. But in the 5G era, it takes only 2 seconds to download the same movie, which can be said to be a "blink of an eye".
The reason 5G is so fast is that it uses higher-frequency radio waves, and the higher the frequency, the greater the bandwidth available and the greater the amount of data that can be transmitted. To draw an analogy, if 4G is a four-lane ordinary highway, 5G is a forty-lane three-dimensional highway, which can transmit dozens of times faster than the former.
If we are careful, we will find an interesting phenomenon: the previous "big brother" will have a very long antenna, and even the early cell phones have a small antenna protruding out, why is there no antenna on the phone now? In fact, the phone is not no antenna, but it is stuffed into the phone. 5G is the reason why the speed of its another big "killer app" is also related to this problem: the higher the frequency of the radio wave, the need to send and receive waves of the antenna will be the shorter. 5G network antenna, short enough to be measured in "millimeters". "The 5G network antennas are so short that they can be measured in millimeters, so a device can put in many antennas, which can form directional beams and send and receive many signals at the same time, which is of course much faster.
