With the coming of the 5G era, major operators are also accelerating the pace of 5G. The follow-up 2G retreat rumors continue, many people are thinking that 5G will soon replace 4, 3, 2G networks.
As operators have already put 5G trial commercial and official commercial time on the agenda, the news about 2G withdrawal has been continuous, but at the World Internet Conference yesterday, he said that when talking about the communication changes in the future 5G era, 5G Will not replace 4, 3, 2G networks soon.
Operators in Japan, South Korea, Singapore, Australia, Canada, and the United States have begun to abandon 2G networks. China Taiwan is also terminating 2G service systems on June 30 this year, even after the retro model 3310 launched by Nokia is on the market soon. It is necessary to upgrade and launch the 3G model to meet the needs of users who have terminated the 2G service area.
China Mobile also announced in August that the "Announcement on the Shutdown of 2G Networks in Some Countries and Regions" announced that some overseas regions will close 2G networks.
Previously, China Unicom's 2G/3G retreat route map showed that China Unicom will start to retreat 2G network in urban area in 2018 and 2G/3G to retreat in 2019. Actively deploying the layout on VoLTE and focusing on the development of 4G services.
5G will not replace 4, 3, 2G soonHowever, at the World Internet Conference on December 4, the Chinese Academy of Engineering and the Director of the China Internet Association, He Hezhen, said that when the communication changes in the future 5G era, a heterogeneous network will be formed, and 5G will not be very fast. In place of 4, 3, and 2G networks, 2G, WLAN, 5G, LTE, and 3G will coexist. Cloud computing is needed to coordinate and optimize resources in a heterogeneous network environment. Clouds are implemented by controlling the cloud, forwarding the cloud, and accessing the cloud. 5G network.
In the future, 1G-4G will be geared towards personal communication, 5G will expand to industrial Internet and smart city applications, enhance mobile broadband for hot-spot high-capacity applications; provide ultra-reliable low-latency for high-speed rail, car networking, and smart factories; Smart cities offer wide coverage and large connections.
According to the national “13th Five-Year Plan†requirements, 5G will be commercialized by 2020. Lu Yimin, general manager of China Unicom, once again confirmed during the World Internet Conference that 5G technology will be trial-commercial in 2019 and is expected to be officially commercialized by 2020. In September this year, China Mobile Chairman Shang Bing also said at the 2017 World Mobile Conference that China Mobile is striving to achieve 5G pre-commercial use in 2019.
Motion Control Sensor is an original part that converts the change of non-electricity (such as speed, pressure) into electric quantity. According to the converted non-electricity, it can be divided into pressure sensor, speed sensor, temperature sensor, etc. It is a measurement, control instrument and Parts and accessories of equipment.
