What Is 4G Technology?

4G technology, short for the fourth generation of mobile communication and its technology, is a technology that integrates 3G and WLAN and can transmit high-quality video images, and the image transmission quality is comparable to high-definition television. 4G mobile communication technology can find the fastest and most efficient communication path between multiple different network systems, platforms, and wireless communication interfaces to perform the most immediate transmission, reception, and positioning actions ^[1] .

4G

4G technology is superior to the previous generation in all respects. Specifically, its advantages are reflected in the following four aspects. ^[3]

In order to meet the increasing demand of mobile communication users for high-speed multimedia data services, and specifically realize the advantages of 4G systems over 3G, 4G mobile communication systems will mainly adopt the following key technologies. ^[4]

1.More standards

Although in theory,

The main technical indicators of 4G technology are as follows: ^[5]

4G technology has been widely used in the field of communications, shortening the distance between people, and it is also widely used in live TV or smart phones. ^[6]

4G technology live TV

The use of 4G networks for TV signal transmission can reduce the cost of transmission on the one hand, improve the quality and speed of TV signals on the other, and even achieve ultra-long distance transmission. Because the operator has set up many signal transmission stations, and the transmission equipment is affordable, the operator has the ability to plan and place equipment in large, medium-sized cities, towns, and rural areas. In this way, there is basically no blind spot in the transmission of TV signals. , Can achieve the purpose that every household can watch TV. 4G communication technology can break through the constraints of mountainous complex terrain and is less affected by natural disasters. Therefore, 4G communication technology is a good choice for live broadcasts in areas with complex terrain conditions and poor climatic conditions. ^[6]

4G Technology Mobile Healthcare

In large and medium-sized hospitals, in order to establish a relatively complete communication system between medical staff and patients, the hospital has set up a comprehensive information-based solution system that relies on mobile medical services, that is, mobile medical care. Utilizing the mobile medical care system, medical staff can carry out the diagnosis and treatment of patients more accurately and effectively with the help of handheld intelligent terminal equipment. If the patient has a demand or has an emergency, he can call the doctor directly through the handheld device. All this is It is realized based on the wireless communication signals and special information transmission lines set up inside the hospital. Through 4G technology, the communication between medical staff and patients is more convenient. On the one hand, it can improve the work efficiency and quality of medical staff. On the other hand, it can avoid delaying the disease and radically reduce the phenomenon of doctor-patient disputes in the hospital. Becoming a life-saving body will not lead to accidents for patients due to untimely treatment. ^[6]

4G technology smartphone

With the continuous development of the economy, science and technology are also changing with each passing day. In China, smartphones have basically become popular in the hands of people in large, medium and small cities. By using a smartphone, people can understand the outside world, and at the same time, they can recognize the difference between the environment in which they live and the environment outside. Most smartphones use 4G communication technology. By using this technology, the call quality of mobile phones can be improved. In addition to the great progress in conversation, the transmission quality and speed of other data have also been greatly improved. For example, 4G smartphones can purchase tickets on the Internet, intelligently arrange more reasonable travel routes for users based on their travel information, and remind users of the weather conditions of their destinations. With 4G smartphones, users can check information and materials that are useful to them through the Internet, and download these materials to their phones, so they can read and learn anytime, anywhere. ^[6]

In summary, with the increasing popularity of smart devices and the continuous advancement of Internet technology, information technology has also ushered in a very important development opportunity. By using 4G communication technology, people's living standards can be upgraded to a new level. With the continuous development and application of new technologies, people will also enjoy more high-quality services. ^[6]
