With The Arrival Of 5G, What New Opportunities Will It Bring To The Development Of The Internet Of Things?
- Jul 21, 2018 -

When it comes to 5G networks, I believe that many people do not have a clear understanding. Because the current 5G network has not been applied in the Chinese market, what is the difference between it and 4G and 2/3G networks? The most obvious difference is the speed. When the 4G network begins to occupy the market around 2010, we will feel that the speed is very fast. Download a movie, send a video, file or photo, etc., and finally do not need to be like a 2/3G network. I waited so hard, but these are not in front of the 5G network, so how fast is the upcoming 5G network? It is reported that its peak theoretical transmission speed can reach 10Gb per second. It can be said that an ultra high definition movie can be downloaded within 1 second. 5G as the fifth generation mobile communication technology will push the mobile market to a brand new one. the height of.

When will 5G really come? At present, Japan, South Korea, the United States and China and Europe are actively studying 5G technology to find breakthroughs in key technologies. There are up to six key technologies for 5G technology, including large-scale antenna array technology or new multi-antenna technology, ultra-dense networking technology, new multiple access technology, D2D communication technology, more flat new network architecture and C-RAN research. Research on potential candidate bands for high frequency bands. Such a daunting task has brought challenges to all countries, and some 5G technologies have begun testing, such as AT&T and Verizon are testing home and enterprise 5G broadband fixed networks.


According to foreign media reports, Huawei is paying close attention to the development of 5G networks. Currently, it is bidding in South Korea and is striving to provide 5G network equipment to three representative mobile operators in Korea. The competitors include Samsung, Nokia and Ericsson, among which LG Uplus operators It has indicated that it is willing to cooperate with Huawei, and Huawei also has a very big advantage in this bidding. This shows how 5G technology is a key and important technology. In fact, China's Ministry of Industry and Information Technology actively deployed and promoted 5G single-point testing technology as early as the end of 2015, and strived to realize the commercialization of 5G networks by 2020.


According to industry insiders, 2020 will be the first year of the 5G commercial network. The breakthrough of 5G technology, the most influential is the Internet of Things industry. It can also be said that the 5G network serves the Internet of Things era. The transmission rate of the future 5G network can reach 10Gbps, and the 4G network we are currently using can be completed in one second. The amount of work done in about 2 minutes, such a high-speed network, then what new opportunities can it bring to the development of the Internet of Things?


5G network will promote the development of intelligent transportation


The 5G network will promote the development of intelligent transportation. From the development stage of intelligent transportation, most vehicles are currently only in the navigation stage, using isolated positioning systems, and the network speed is not up to the requirement. When we use navigation Even if we go wrong, the navigation will not tell us in time, we will remind us after a minute or two, and some of the more remote places, navigation can not guide, sometimes the map is not updated in time, so we are often very Difficult to reach the destination, which greatly affects the user experience. The main reason is that the transmission efficiency is not enough, because the information cannot be transmitted in real time, so the information cannot be updated in real time. When the 5G network arrives, we believe that these problems can be solved very well.


Unmanned technology is also the lively direction that the world is currently studying. This technology requires millisecond delay. According to a survey by the National Highway Traffic Safety Administration, 80% of road traffic accidents are caused by the driver 3 seconds before the accident is discovered. Caused by the general idea. An experiment by Daimler-Benz also showed that if the driver is alerted 0.5 seconds ahead, 60% of the rear-end collision accident can be avoided; if the driver can get the warning and take measures 1.5 seconds in advance, 90% of the rear-end collision can be avoided. ACCIDENT. The 4G network we are currently using has a rate delay of 50 milliseconds, which basically does not realize real-time control. If the 5G network arrives, the end-to-end delay takes only 1 millisecond, which can fully meet the demanding requirements of automatic driving.




While 5G networks have the characteristics of high speed and low power consumption, we can imagine using relevant technologies to combine data such as road conditions, vehicle conditions, traffic lights, and congestion levels into an intelligent transportation network. Any vehicle driver can truly 360 degrees. Understand the surrounding car conditions, clearly know the traffic conditions in front of the road section, the degree of blockage, and then choose the right speed or route. This will fully realize the vision of unmanned driving. People sitting in the car can be completely assured.
