5G communication tower, also known as the fifth generation wireless mobile communication tower, is an advanced millimeter wave transmitting frequency range of 30-300GHz to provide people with high-speed spread spectrum communication, but even if Guangxin Communication 5G communication is the transmission speed in millimeter wave At ultra-high speeds, as the transmission distance increases, it will appear that these millimeter waves cannot pass through buildings and walls, so during the propagation process, smaller transmission signals are required. This technology evolved from contactless radio frequency identification (RFID) and was jointly developed by Philips and Sony. Its technology is based on RFID and interconnect technology. Near field communication is a short-range high-frequency radio technology that operates at a distance of 20 cm at a frequency of 13.56 MHz. Its transmission speed is 106 Kbit / s, 212 Kbit / s or 424 Kbit / s.

5G communication tower is the fifth generation of wireless mobile communication technology, and its speed is 10 times faster than the current 4G technology. However, there is currently no standardized 5G technology, just like when 4G networks first emerged, the development of 5G networks is also underway. It was expected that by 2020, 5G networks would be fully popularized. As a Chinese mobile company, ZTE previously launched the first 5G smartphone, which can provide 1Gpbs network speed. There are currently four factors determining 5G networks. The first is millimeter wave. Based on the 4G network, it is equipped with spectrum in the range of 2-6GHz. At present, more and more equipment is added to the spectrum. This is like an increasing number of vehicles on a road, making the network Congestion is also increasing, eventually reducing the transmission speed. To increase speed, the previous spectrum had to be expanded.

Short-range high-frequency wireless communication technology allows non-contact point-to-point data transmission and exchange of data between electronic devices. At present, people use millimeter waves with smaller wavelengths in 5G propagation, so people use multiple smaller base stations instead of a large base station with high power. This method reduces the possibility of attenuation through some physical components. It even eliminates the disadvantage that millimeter waves cannot transmit signals to longer distances. When we use this smaller radio wave, it is very easy to achieve frequency reusability.

In a 4G network, there are usually more than a dozen MIMO ports used to transmit signals, but with the popularity of 5G networks, this number will increase by 4 times, so that the signal travels faster in all directions. However, with the increase of network complexity, it is necessary to make great technical improvements in transmission. In addition, beamforming is also an important technology, which can eliminate some signal interference during the 5G network transmission process, instead of letting all ports transmit signals in all directions, by making a single port send in a specified direction Higher beam signals to reduce signal interference and even signal attenuation.

For 5G, the latest network technology, it will also greatly improve people's daily lives and work methods. Researchers predict that by 2020, the traffic will reach 1,000 times that of the current time. With the rise of the electronics industry, the Internet of Things and virtual reality have begun to enter people's daily lives. As a result, the number of Internet-connected devices will increase with each passing day, which will also cause more and more traffic. In addition, low latency is also a great advantage of 5G networks. Network latency is basically the delay that occurs when data is communicated through the network. This is the time it takes for the network to transmit data packets from one destination to another. Self-driving cars and self-driving cars are moving, and people need shorter delays in network transmission.

In addition, there are some requirements, such as the peak speed of Gbps and the bandwidth requirements of applications, etc., 5G networks can effectively use the spectrum. In the mobile spectrum, the number of users is quite high, but in some other spectrums, there are very few users. This is the current status of wireless networks. Therefore, researchers are working on the development of unknown spectrums. They play different roles. For example, mobile communication has its own spectrum, TV signals have its own dedicated spectrum, and radios have their own independent spectrum. Earlier, at the beginning of 5G network research and development, some people suggested that why we cannot allocate some free spectrum to users of crowded spectrum. Therefore, knowledge and better use of spectrum are the key to the success of 5G networks. Of course, with the continuous development of the Internet, people's exploration of unknown fields has never stopped. I believe that in the future, people's lives will become more and more convenient with the change of technology.
