What s the use of 5G so fast? Why are 5G networks so fast?

Because in the future, it will be the era of the Internet, and the Internet can solve many problems quickly.

5G is so fast that it can meet people's pursuit of network speed and allow people to better enjoy the convenience brought by the network.

He is particularly fast in the processing of big data, as well as artificial intelligence.

Because people are using the web a lot these days, it's definitely useful to be fast.

There are certainly a lot of uses, which can minimize latency, which is excellent for security systems.

The read and write speed of the hard drive will affect the speed of your use, so use the SSD first. In order for 5G transmission to achieve higher transmission speeds, it is first necessary to achieve a breakthrough in frequency use.

The transfer of information has become faster and the amount that can be transferred is much larger.

It has many uses, which can make technology develop faster and make life better.

It has many uses, first of all, it can save people a lot of time, and it can also drive many industries.

Invited to the industry issue.

5G network. The increase in network speed is mainly due to the multiplication of bandwidth and multi-stream, followed by the enhancement of new algorithms such as beamforming and coding.

The most critical aspect of the increase in 5G speed is the increase in bandwidth.

The bandwidths that 4G (LTE) can support include a maximum bandwidth of 20MHz, while the sub-6G supported by 5GNR has a maximum bandwidth of 100MHz, mmWave.

Some support 400MHz bandwidth.

The higher the bandwidth, the faster the network.

However, due to the increase in bandwidth, 5GNR must go to a higher frequency to find continuous 100MHz bandwidth, which also leads to 5G base stations.

The density of construction needs to be greater than that of the current 4G base stations.

The minimum requirement for 5G terminals is 2T4R, while the requirements for 4G terminals are 1T2R. Another major reason for improving network speed in 5G is to support multi-streaming.

LTE phones can only reach a speed of 150Mbps, which is due to the fact that 4G phones only have 2 receiving antennas and can only reach a speed of 150Mbps under 2*2MIMO.

5G has higher requirements for the antenna configuration of the terminal, and it needs to support at least 2T4R, the current 5G mobile phone.

This is the configuration of the .

For 5G terminals, 8*8 MIMO can increase the speed by 4 times compared to 2*2 MIMO, while 8*4 MIMO can increase the speed by 2 times.

Some other technologies that ensure the high speed of 5G.

5G has also introduced Massive MIMO technology, a large-scale antenna array technology based on beamforming, which can effectively control interference, realize multi-user space division multiplexing, and also provide multi-stream, currently 64T6R can support 16-32 streams, achieving a capacity gain greater than 5 times that of 2T2R.

Then there is 5GNR, some interference cancellation technology, refined carrier utilization, and PLOAR LDPC coding, which also makes 5G faster.

All in all, 5G is much faster than 4G, mainly because 5G uses higher bandwidth, multi-stream antenna technology, and new coding, high-order modulation and other technologies.

"5G network" means fifth-generation mobile communication network. 5G is characterized by fast transmission rates, more connections to smart devices, improved network connectivity, and increased cell phone and battery life.

It has been confirmed from the three major operators that the relevant departments of the state have approved the pilot construction of 5G networks in some cities such as China Unicom, China Telecom and China Mobile. China Unicom disclosed that it will carry out 5G pilots in 16 cities including Beijing, Tianjin, Qingdao, Hangzhou, Nanjing, Wuhan, Guiyang, Chengdu, Shenzhen, Fuzhou, Zhengzhou and Shenyang.

China Mobile said it will carry out 5G field tests in five cities: Hangzhou, Shanghai, Guangzhou, Suzhou and Wuhan, with more than 100 5G base stations built in each city, and 5G service application demonstrations in 12 cities including Beijing, Chengdu and Shenzhen.

China Telecom's 5G pilot cities are currently tentatively designated as "6+6", including the six previously identified cities of Xiong'an, Shenzhen, Shanghai, Suzhou, Chengdu and Lanzhou. In addition, the scope of the pilot will continue to be expanded according to the requirements of relevant national ministries and commissions, and six more cities will be added.

Recently, Shandong Unicom announced that in the communication room of Shandong Unicom Qingdao Branch, technical experts have successfully achieved high-speed data transmission on the 5G test network built by technical experts. This means that Shandong Unicom's first 5G call has been successfully realized, and 5G is one step closer to the lives of ordinary people.
