The speed can reach 10,000 times that of 5G, and the official interpretation of 6G is here

In the era of mobile Internet, whoever has more advanced mobile communication technology means that he or she has more "strategic resources". As we enter 2020, I believe that the most concerned topic during this period is the degree of popularization of 5G networks. Because it not only determines the user experience when the 5G wave comes, but also affects the purchasing decisions of many consumers.

I believe that many users who have not yet purchased a 5G phone are in an urgent wait-and-see state, hoping that the 5G network coverage can be improved, and at the same time expecting that the price of 5G phones and 5G packages can be reduced to a more civilian price. But do you know? When you have not yet chosen to purchase a 5G phone, the research and development of 6G network is already on the way.

Just a few days ago, the 3GPP organization officially announced the freezing of the 5G R16 standard at its 88th meeting, which means the completion of the first evolution version standard in the 5G era. This version gives 5G networks more new performance and new functions, including higher performance and lower latency communication capabilities, more sensitive delay-sensitive network service capabilities (for the industrial Internet), more efficient V2V and V21 communication capabilities (for the Internet of Vehicles), and more accurate air interface positioning capabilities.

It can be said that the freezing of the R16 standard means that the current 5G capabilities have begun to become comprehensive. At the same time, many countries have announced that they have entered the 6G research and development stage. So what is 6G? What changes will the 6G network bring to our lives? I believe that many people, like me, are still in a state of confusion. Here comes the official interpretation.

Recently, Dr. Liu Guangyi, chief expert of China Mobile Research Institute and head of the 6G project, answered questions about the parameter indicators of 6G networks. Next, we will explain this series of values ​​one by one.

Gigabit Internet Speed

It is understood that the peak network speed of 6G network can reach 1000Gbps, and the actual user experience is also 1Gbps. What does this mean? We can think of signal transmission as a highway. Under normal circumstances, a highway has three lanes and can accommodate three cars at the same time. But if we widen this road to 1000 lanes, it means that 1000 cars can pass through at the same time. This is the difference between 6G Gigabit network and traditional network. By then, the cloud era will no longer be a paper talk.

The 5G network we are currently talking about can theoretically reach a peak speed of 10Gbps, but in reality it is only 0.1 to 1Gbps.

Sub-second latency

In addition to the gigabit network level under 66G network, in terms of latency, 6G can also process massive amounts of data in real time, with latency reaching sub-second levels. Currently, the network latency on wide area networks and the Internet is basically at the millisecond level, and the latency of 5G networks is also at the millisecond level, while the sub-second latency is much lower than the millisecond level (I haven't found relevant information, and those who know can explain it)

Reliability ≈ Wired Network

In terms of reliability, wired networks rely on Ethernet, hubs and switches to exchange data, and have more obvious reliability than wireless networks. Wireless networks are easily affected by home appliances, microwave ovens or other devices running at the same frequency. However, according to Dr. Liu Guangyi, 6G networks will be very close to wired networks in terms of network reliability.

High-speed mobile communications

In a high-speed mobile environment, the radio communication system often produces a very obvious Doppler frequency shift, which causes the channel to change rapidly. Therefore, the performance of the mobile communication system is not stable in such an environment. This is also one of the weaknesses of the current 5G network. However, the speed of the 6G network can reach 1,000 kilometers per hour, which means that in a high-speed mobile environment, the 6G network can also maintain higher stability. Not only on the high-speed rail, but also on the plane in the future, you can also surf the Internet.

Better spectral efficiency

In addition to the above points, 6G network has another more prominent advantage than 5G network, that is, utilization rate. It is understood that the utilization rate of 6G network can reach 2~3 times that of 5G, which is particularly important for operators, as it can not only reduce costs, but also reduce daily expenses.

In general, although 5G technology is still in the popularization stage, it has to be said that many countries and companies have already started the technical research and development of 6G networks. Perhaps many people do not understand that it is too early to develop 6G now, but you have to understand that the application of 5G networks has played a key role in the industrial field in addition to the civilian field. Once 6G appears, it will have extraordinary significance for some high-tech fields.
