Five characteristics of 5G: 1. High speed; Compared with 4G network, 5G network has higher speed. 2. Ubiquitous network; Ubiquitous network has two levels of meaning, one is broad coverage, and the other is deep coverage. 3. Low power consumption. 4. Low latency; 5G’s minimum latency requirement is 1 millisecond, or even lower. 5. Everything is interconnected.

Fifth generation mobile communication technology (English: 5th generation mobile networks or 5th generation wireless systems, 5th-Generation, referred to as 5G or 5G technology) is the latest generation of cellular mobile communication technology, following 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems extend. The performance goals of 5G are high data rates, reduced latency, energy savings, cost reduction, increased system capacity and large-scale device connectivity.
Five characteristics of 5G
1. High speed
This is the biggest feature of 5G One feature is that compared to 4G networks, 5G networks have higher speeds, 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;
The ubiquitous network has two levels of meaning. One is broad coverage and the other is deep coverage.
Widely refers to the need for wide coverage in all places where our society lives. In the past, high mountains and valleys did not necessarily need network coverage because there were very few people living there. However, if 5G can be covered, a large number of sensors can be deployed to conduct environmental monitoring. , air quality and even landform changes, earthquake monitoring, which is very valuable. 5G can provide networks for more such applications;
Depth refers to the fact that in our lives, although there are already network deployments, higher quality in-depth coverage is needed. We already have a 4G network at home today, but the network quality in the bathroom at home may not be very good, and there is basically no signal in the underground parking garage. It is now acceptable. With the arrival of 5G, bathrooms, underground parking garages, etc. that used to have poor network quality can be widely covered with good 5G networks;
3. Low power consumption
5G must have power consumption requirements to support large-scale IoT applications. 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
A new scenario of 5G is the highly reliable connection of 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;
Unmanned vehicles require interconnection between the central control center and the vehicle, and between vehicles. In high-speed operations, a brake , 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 and car braking. Control response;
5. Internet of Everything
Entering the intelligent era, in addition to mobile phones and computers and other Internet devices that need to use the Internet, more and more smart home appliances and devices can More different types of devices such as wearable devices, shared cars, and 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 makes it possible for these devices to become smart devices. ;
