Recently, the Ministry of Industry and Information Technology announced that it will issue 5G commercial licenses in the near future. The Ministry of Industry and Information Technology has publicly stated that 5G in China already has a commercial basis. In the near future, the Ministry of Industry and Information Technology will issue 5G commercial licenses, and China will officially enter the first year of 5G commercial. With the continuous improvement of commercialization, it will quickly penetrate into all industries and even the lives of the general public. The doubling of data transmission speed will directly bring more innovative possibilities to the AI field. In China, excellent AI start-ups such as Ignorance Technology, Shangtang Technology, Video++ and Ito Technology were born. In the era of 1G cellular data, 2G information, 3G picture and 4G video, what will 5G bring to me?



The 5G Age is Coming


As the fifth generation mobile communication network, the peak theoretical transmission speed of 5G network can reach 1GB per 8 seconds, which is hundreds of times faster than that of 4G network. For example, a 1G movie can be downloaded in 8 seconds. Comparing the FDMAT DMA CDMA technology applied by the three major suppliers of 2G/3G/4G, we call 5G technology as new radio for the time being. In terms of coverage of 5G base stations, in order to guarantee user services, Massive-MIMO multi-input and multi-output technology has brought abundant spatial freedom, signal reliability improvement and regional information throughput enhancement. The number of traditional TDD antennas is 2, 4 and 8, while Massive-MIMO will reach 64/128/256. Like the storage and transmission of information, multi-channel means that the path of data arrival is faster. 5G base station is the same as WIFI in our home, using the way of coverage.



Compared with 4G network, 5G utilizes high frequency band, which makes great difference in speed, delay, number of connections and mobility. In terms of delay, 5G's delay time is greatly reduced, which has a great impact on many real-time applications, such as games, videos, autopilot, etc. The maximum number of connections per square kilometer of 5G is hundreds of times that of 4G. In addition, another change of 5G is the change of transmission path. In the past, we used to make telephone calls or transmit photos, and the signals were transferred through the base station. But after 5G, the transmission between the equipment and the equipment can be carried out directly, without any need to pass through the base station.
