Shenzhen.
Jia Xingdong, director of the Shenzhen Municipal Bureau of Industry and Information Technology, said that as of August 14, 2020, Shenzhen had built 46,480 5G base stations, completing Shenzhen’s previous goal of completing the construction of 45,000 5G base stations by the end of August ahead of schedule. . Currently, Shenzhen ranks first in the world in terms of scale of 5G industry and shipments of 5G base stations and terminals.
Five features of 5g
1. High speed
This is the biggest feature of 5G. Compared with 4G network, 5G network has higher Speed, and the peak requirement for 5G base stations is no less than 20Gb/s. Of course, this speed is the peak speed and is not the experience of every user. With the use of new technologies, there is room for improvement in this speed.
It only takes 33 seconds to complete under the 5G network, and the rate per second reaches 726Mbps, while the download rate of the 4G LTE Cat.12 network is only 62.2Mbps, which takes 6 minutes and 25 seconds;

2. Ubiquitous Network
With the development of business, network services need to be all-encompassing and widespread. Only in this way can we support richer services and be used in complex scenarios;
3. Low power consumption
To support large-scale IoT applications, 5G must have powerful consumption requirements. 5G can reduce power consumption and allow most IoT products to be charged once a week, or even once a month, which can greatly improve user experience and promote the rapid popularization of IoT products;
4. Low latency
1. A new scenario of 5G is high-reliability connection for driverless and industrial automation. For information exchange between people, a delay of 140 milliseconds is acceptable, but if this delay is used for driverless driving and industrial automation, it is unacceptable. The minimum requirement for 5G latency is 1 millisecond, or even lower. This places stringent requirements on the network. 5G is an inevitable requirement for applications in these new fields;
2. Driverless cars require interconnection between the central control center and the car, and there should also be interconnection between cars. In high-speed operations, When braking, information needs to be sent to the car instantly to react. In about 100 milliseconds, the car will rush dozens of meters. This requires information to be sent to the car in the shortest delay for braking. Movement and car control response;
5. Internet of Everything
In the era of intelligence, in addition to mobile phones and computers and other Internet devices that need to use the Internet, more and more smart home appliances, wearable devices More different types of equipment such as equipment and private cars, as well as public facilities such as lights, need to be connected to the Internet. After being connected to the Internet, real-time management and intelligent related functions can be achieved, and the interconnectivity of 5G also allows these devices to be connected to the Internet. The possibility of becoming a smart device;
