Let's talk about 5G that you still can't see
As an IOT novice, I will talk about the hottest topic of the Internet of Things in the past two years, and that is the 5G era!
At the 2019-2020 Shenzhen Internet of Things Exhibition, everyone is looking for 5G-related information and equipment, and everyone seems to want to unveil the mystery of the 5G era. The word "5G" is introduced in Baidu Baike,
Here is the quote
The fifth generation of mobile communication technology (English: 5th generation mobile networks or 5th generation wireless systems, 5th-Generation, referred to as 5G or 5G technology) is the latest generation of cellular mobile communication technology, also following 4G (LTE-A, WiMax), 3G ( Extension after UMTS, LTE) and 2G (GSM) systems. The performance goals of 5G are high data rates, reduced latency, energy savings, cost reduction, increased system capacity and large-scale device connections. The first phase of the 5G specification in Release-15 is to accommodate early commercial deployment. The second phase of Release-16 will be completed in April 2020 and will be submitted to the International Telecommunication Union (ITU) as a candidate for IMT-2020 technology [1]. The ITU IMT-2020 specification requires speeds of up to 20 Gbit/s, which can achieve wide channel bandwidth and large capacity MIMO.
On Baidu Encyclopedia, we can see several main keywords "high data rate", "low latency", and "wide link". The high rate is easier to understand. It is faster than the current 4G transmission speed, such as 4G per second. Download 20-50M and now 5G can be 250M or higher, the next movie, game will only take a few seconds! A low-latency, more vivid case is live TV broadcast, real-time transmission of live images, simple understanding means what you see is what you see, wide link means that there are more connected devices, and in the 4G era, you will find mobile phones in a place with many people Internet speed will be very slow, 5G will be relatively much better. This is just my little white understanding, welcome all the big guys to give me advice!
We have been in touch with the topic of 5G for several years, but there are very few devices around us that can see 5G landing. The only thing we can see in 2020 is 5G mobile phones, but when we get 5G mobile phones, we will What can be done? 5G content is almost blank. But if you only know that 5G is watching movies and playing games on mobile phones, it would be too one-sided. 5G is the cornerstone of changing the times and the veins of the Internet of Everything. Wu Hequan, academician of the Chinese Academy of Engineering, Tan Jianrong, academician of the Chinese Academy of Engineering, Li Zhengmao, general manager of China Telecom, and Yu Xiaohui, vice president of China Academy of Information and Communications Technology, all shared their views on the new 5G infrastructure. New infrastructure is the three major aspects of innovative infrastructure, integrated infrastructure and information infrastructure. It forms a mutually integrated relationship with the Internet of Things (IoT), greatly strengthening the capabilities of the sensing end, network layer, and platform layer. The integration of 5G and new infrastructure will greatly promote the interconnection of everything.
What other 5G is closely related to us?
1. Smart city, when your city is equipped with the Internet of Things brain, you will find that the traffic is not so congested and the resources are more conserved!
2. Telemedicine
3. Artificial intelligence. You can’t see a lot of manual labor on the production line.
4. Unmanned driving, smoother traffic and fewer traffic accidents.
5. Smart finance
6. Smart agriculture.
7. Smart education, entertainment and intelligence. Home, remote monitoring, etc.
But the potential of 5G is by no means limited to this, as time goes by, there will be more brand-new application scenarios appearing unknowingly. But for the future, no one of us can predict it. Just like when 4G LTE was conceived in 2004, no one could have imagined that smart phones would bring such a big change to the world. Therefore, if you feel that the above 5G application scenarios are not sci-fi enough, you may wish to leave some room for imagination and look forward to more surprises from 5G. In addition, the deployment of 5G also takes a long time. Although the earliest commercial deployment can start in 2019, the real widespread adoption of 5G is expected to wait until 2025.
