Recently, it was said on the Internet that 5g network can download 30 movies in one second, which makes everyone think it's amazing. What is 5g network like? What's the difference between 5g and the 4G network we currently use?
Once 5g network is put into commercial use, it will not only bring the communication industry into a new round of development, but also drive a number of trillion scale emerging industries.
At present, many countries and regions attach great importance to 5g business, and the United States, the European Union, South Korea, Japan and China all plan to launch 5g network business deployment in the second half of 2019, and official business in 2020. With the release of 5g international standard, the global 5g industry competition will become increasingly fierce.
Many market institutions predict that the typical Internet of things industry segments, such as the Internet of vehicles, big data, cloud computing, smart home, UAV, are quite mature in terms of technology and application, but the communication capacity of the existing 4G network greatly limits the development of the industry. With 5g's official commercial use, the network problems will be solved, the above services will be applied smoothly, and the relevant industries will usher in a period of rapid development.
It is worth noting that the 5g standard planned to be launched will no longer have multiple technical versions, but the only standard forming a unified integration.
If 5g network comes, 5g network can only be used by 5g network supporting mobile phones, and 4G / 3G / 2G is also supported by 5g network supporting mobile phones.
But 4G mobile phones only support 4G / 3G / 2G. 4G / 3G / 2G will not be cancelled after 5g network is launched, that is to say, 4G / 3G / 2G of operators is still running, so as long as 4G / 3G / 2G mobile phones are still available, but these mobile phones can not use 5g network.
What's the difference between 5g and 4G
1. First and foremost, the 4G network based on LTE is undergoing a rapid deployment, while the 5g network is still in the stage of Research Report and implementation project, and the large-scale deployment of the latter is expected to wait until 2020.
2.4G and previous mobile networks mainly focus on the provision of original bandwidth, while 5g aims to provide ubiquitous connectivity, laying the foundation for fast and flexible network connectivity, whether users are in skyscrapers or subway stations.
3.5G network will not exist independently, it will be a combination of multiple technologies, including 2G, 3G, LTE, LTE-A, Wi Fi, M2M, etc. In other words, 5g is designed to support a variety of different applications, such as the Internet of things, Internet wearable devices, augmented reality and immersive games.
Unlike 4G, 5g networks are capable of handling a large number of networking devices and traffic types. For example, 5g can provide ultra-high speed links when dealing with HD video online playback tasks. In the face of sensor network, it can only provide low data transmission rate.
4.5g network will take the lead in using new architectures such as cloud ran and virtual ran to promote the establishment of a more centralized network, and maximize the use of server farms through localized data centers on the edge of the network.
5. Finally, 5g will take the lead in using cognitive radio technology to let the network infrastructure automatically determine the type of frequency band provided, distinguish mobile and fixed equipment, and adapt to the current situation in a specific time. In other words, 5g can serve both industrial networks and Facebook applications.
