5g three characteristics

If you think that 5G only brings faster video downloading and smoother Internet access, you are wrong. 5G can bring us much more than this.

In the 5G era, everything in front of you can be connected together. Water bottles, cars, air conditioners, TVs, crops...all things are truly interconnected.

5G has three major characteristics: ultra-high speed, ultra-large connection, and ultra-low latency. The communication rate will be 10-100 times higher than that of 4G. Cloud computing, AI, drones, VR and big video in the 5G ecosystem will develop simultaneously. (Recommended learning: PHP video tutorial)

5G network has three major performances and two major unique capabilities, exploring new services, new applications, and new business models for all walks of life, cultivating new market and laid a solid foundation.

The three major performances are ultra-high speed, ultra-large connection, and ultra-low latency.

Business traffic has grown rapidly since 4G, and major industries are constantly exploring new network applications. Communication networks are facing great pressure to expand capacity, and these three major properties of 5G networks can enable existing networks to break through capacity bottlenecks. Conducive to cultivating new businesses in all walks of life.

The two unique capabilities are network slicing and edge computing.

If the network is compared to a transportation system, then vehicles are users and roads are the network. As the number of vehicles increases, the roads become congested. In order to alleviate congestion, the transportation department will conduct diversion management of vehicles according to type and operation mode, such as setting up rapid bus lanes, dedicated lanes for non-motor vehicles, etc.

The same goes for the Internet.

From the mobile Internet between people to the Internet of Everything, the network will become more and more complex and congested. We need to carry out offload management of the network, that is, network slicing.

Network slicing is to divide the operator's physical network into multiple virtual networks based on different service requirements, such as latency, bandwidth, security and reliability, etc., to flexibly respond to different network applications. Scenes.

Specifically, 5G networks can be divided into three types of application scenarios:

1. Enhanced mobile broadband (eMBB);

2. Ultra Highly reliable, low-latency communication (uRLLC);

3. Massive machine type communication (mMTC).

Different application scenarios correspond to different 5G network performance. It is expected that domestic operators including China Mobile will focus on eMBB services to achieve large-scale commercial trials in 2019, and will gradually commercialize uRLLC and mMTC services after 2020.

On the other hand, we can use the living habits of octopus to understand what edge computing is.

Octopus has the highest IQ among invertebrates. When hunting, they move very dexterously and quickly. Their arms and legs are highly coordinated and never get entangled or knotted. This is because the octopus has a huge number of neurons of 60 % is distributed on the eight legs of the octopus, and only 40% of the brain is a structure of "multiple cerebellums and one brain", similar to distributed computing.

Edge computing is also a kind of distributed computing, which transfers the processing of data, the running of applications and even the implementation of some functional services from the network center to nodes at the edge of the network.

In the 5G era, the number of devices will increase significantly, and a huge amount of data will be generated at the edge of the network. If these data are processed by the core management platform, there will be problems in agility, real-time, security and privacy, etc. However, edge computing can process massive amounts of data nearby, and a large number of devices can work together efficiently, so many problems can be easily solved.

The three major performances of 5G network can meet the continuous expansion of the scale and scope of the traffic market and the industry’s rigid requirements for low latency, and develop new applications and services; the two unique capabilities can bring lower network costs, achieve efficient operations, and cultivate new business models.
