What Is a 4G Network?

4G communication technology is the fourth-generation mobile information system. It is a better improvement on 3G technology. Compared with 3G communication technology, it has a greater advantage. A good combination makes the transmission speed of the image faster, and makes the quality of the transmitted image and the image look sharper. The application of 4G communication technology in intelligent communication equipment allows users to access the Internet more quickly, and the speed can reach 100M. ^[1]

4G communication technology

On the whole, the service data provided by 4G networks are mostly all-IP networks, so they can meet the development needs of mobile communication services to a certain extent. However, with the rapid development of economic society and the Internet of Things technology, new types of mobile communication services such as cloud computing, social networks, and Internet of Vehicles have been continuously generated, which have put forward higher-level requirements for communication technologies. In the future, mobile communication networks will completely cover our office, entertainment, rest areas, and residential areas, and the demand for communication networks in each scenario is completely different. For example, some scenarios have high requirements for high mobility, and some scenarios require high traffic density. However, these requirements are difficult to meet with 4G networks. Therefore, in response to the new needs of future users, we should focus on exploring higher speed and more advanced mobile. Network communication technology. ^[7]

The fourth-generation mobile communication technology has high bandwidth, so it displays high-definition pictures and videos to meet people's needs. 5G was born for the Internet of Things. Compared with other network technologies, the 5G communication network has a larger capacity and ensures a faster Internet access rate. Generally, it is connected to the Internet device through a smart terminal for network transmission. 5G technology provides a larger network platform for the Internet of Things, so it meets larger operational needs. 4G networks can provide certain services to smart users, but cannot be optimized in a timely manner based on the changes and needs generated by the Internet of Things. The 5G communication network supports several times more terminal devices than the 4G communication network supports, while ensuring lower energy consumption. The 5G communication network solves the situation where the 4G network cannot continuously play games in real time. As a communication network system with high efficiency and low energy consumption, under the premise of continuous updating and transformation of Internet technology, 5G communication networks have undergone certain changes, resulting in changes in the service targets of related industries. ^[8]
