The mobile phone era has brought great convenience to our communication and got rid of the period of using letters for communication. Before, our understanding of the network remained at the level of 3G and 4G. With the unremitting efforts of scientific and technological personnel, we have reached a new height, that is, 5g network. What different experiences and technologies will 5g bring us?
The technical features of 5g can be described as "fast", "stable" and "dense", and these three features' catalyze 'three types of application scenarios respectively.
First, 5g 'fast' - under the coverage of 5g network, downloading a movie with a resolution of 4K theoretically takes no more than 18 seconds, but the speed brings not only quantitative changes.
At the exhibition, the New York Times announced the establishment of a 5g news laboratory. Future news stories will provide interactive and immersive 3D streaming media images according to time and readers' location, so that readers can watch the news immersively.
People in the industry believe that 5g will bring new life to the 'augmented reality / hybrid reality' (AR / MR) technology of 'only listening to thunder and no rain' in recent years. Nick middot, CEO of American start-ups' third eye '; Cherukuri can't wait for the full deployment of 5g. He said that only 5g speed can make this technology go out of the experience area and form an industrial scale.
Second, 5g is' stable '- if it is only the increase of speed, it is not a qualitative change. The most remarkable feature of 5g is low delay and high reliability, that is, it is stable in any environment.
Chris middot, CEO of mepis in the medical technology industry; Molly said at the exhibition that 5g network allows doctors to complete accurate craniotomy with the help of 'mixed reality' tools, which is more accurate than 'surgical accuracy'. This sci-fi technology can only be realized in the 5g era, because 5g signal is' continuous chip '. One second Caton is a little unpleasant for watching movies at most, but it will be life-threatening in the field of medicine.
One of the technical requirements of 5g is to support equipment with a speed of up to 500 kilometers per hour. Therefore, the industries promoted by 5g technology also include driverless vehicles. For example, the average person's reaction speed when stepping on the brake is about 0. 4 seconds, and the reaction speed of unmanned vehicle in 5g scenario is expected to be less than 1 millisecond, which is undoubtedly one of the foundations for unmanned driving to win the trust of users.
Driverless is closer to reality because of 5g, and this huge cake has also attracted many enterprises. On the CES booth, whether chip giants such as Intel and NVIDIA, or start-ups such as Chinese artificial intelligence enterprise horizon, people feel that they make 'unmanned cars'.
Third, 5g 'dense' -- 5g network can support 1 million devices per square kilometer, which is very helpful to the development of the Internet of things.
At this year's exhibition, smart city has become a new product category, and its underlying technology is the Internet of things. Steve & middot, exhibition organizer and head of market research business of American consumer Technology Association; Konig quoted a common saying in the industry that people will be connected in the past 30 years and things will be connected in the next 30 years.
The international standards organization's' third generation partnership program '(3GPP) defines three 5g scenarios, namely, enhanced mobile broadband, low delay, high reliability and large-scale Internet of things services, which exactly correspond to the three characteristics of' fast ',' stable 'and' dense '.
At present, most 5g application scenarios are just a prospect, some may progress slower than expected, or even be eliminated, and some unexpected scenarios may emerge to form subversive innovation. But it is certain that 5g will trigger a revolution that will greatly change the way of life, which is also an important driving force for countries to promote the deployment of 5g.
