The work of the Ministry of Industry and Information Technology, China's IMT-2020 (5G) promotion group and the 5G commercial plans of the three major operators show that China will launch the second phase of the 5G network test in 2017, the large-scale trial network in 2018, and the 5G network in 2019. , the fastest commercial 2020 5G.
Recall that more than a decade ago, GPRS mobile phones became popular, and the first batch of MMS mobile phones such as the Nokia 7650 were listed. It is incredible that mobile phones can take photos and send pictures. Of course, the mobile phone can also start to access the Internet. GPRS does not need dialing, WAP, and no delay in calling the phone, but the speed is still very slow. It takes a long time to open a tens of KB of photos.
Then 3G is coming, the speed of the mobile phone can already watch 720P video; now, my 4G mobile phone speed can reach 7.7MB/s download speed, sometimes the traffic is enough, I will even use 4G to download several GB games. It is more stable than the fake 100M broadband in the home.
and then? Nature is 5G. So, how fast will 5G be, what changes will it bring to our lives? Take a look.
How fast is 5G? What is the use?
At present, the maximum speed of 4G/LTE can reach 1000Mbps. Of course, this is 4G/LTE Advanced. At present, it is still at the laboratory level, and there are basically no operators in the world that can be commercialized. So what about 5G? The answer is 10000Mbps, which means that the download speed per second can reach 1GB per second, and the love action movie is finished in 1-2 seconds.
In addition, this is just the most intuitive feeling of our ordinary consumers. After all, the download speed is fast and no one likes it. There are still many hidden benefits. It is important to know that with the development of Internet of Things technology, more and more devices need to access the network, such as self-driving cars, drones, wearable devices, outdoor live broadcasts, etc., compared to public Wi-Fi. -FI, these devices are obviously more suitable for digital cellular networks, and 5G's powerful data carrying capacity is quite advantageous.
At the same time, 5G networks will have more flexible and intelligent connectivity. For example, some devices need to transmit data quickly, others require less delay and more stable connections. 5G can automatically determine the usage scenarios and provide the best user experience.
When will 5G be launched?The 5G deployment is being implemented step by step among operators in various countries. According to the latest news, China Mobile's 5G network is expected to be commercialized by 2020, basically in line with other developed countries.
In the US, Verizon has announced joint development with Samsung and is expected to go live in 2020. In South Korea, it is expected to provide standard 5G services during the 2018 Winter Olympics, but it may be limited to Olympics and regional services; Japan may implement commercial 5G networks during the 2020 Summer Olympics.
summaryOf course, just like the beginning of 4G commercial, don't expect the 5G network to reach the theoretical maximum speed just on the line. It should be noted that 4G/LTE Advanced is currently not commercially available on a global scale ( Qualcomm Shen Lei Interpretation: Gigabit LTE is paving the way for 5G ). But just like every mobile network update, consumers will only use mobile phones to access the Internet faster and faster.
