4G LTE antenna direction, gain and power

　　4G LTE antenna direction, gain and power

　　1. What are the important factors affecting the performance of 4G LTE antenna?

　　In radio communication, 4G LTE antenna is the interface of external medium, and 4G LTE antenna can radiate and receive radio waves.

　　When 4G LTE antenna transmits, it can convert high-frequency current into electromagnetic waves and convert received electromagnetic waves into high-frequency current. The direction, gain and power of 4G LTE antenna are important factors affecting the performance of 4G LTE antenna.

　　4G LTE antenna gain is an important parameter of 4G LTE antenna. The definition of 4G LTE antenna gain is related to omnidirectional 4G LTE antenna and half-wave dipole 4G LTE antenna.

　　Omnidirectional radiator is a radiator with the same power in all directions, and there is a 4G LTE antenna gain in one direction.

　　DBi represents the reference value of 4G LTE antenna relative to omnidirectional radiator, and dBd is the reference value relative to half-wave dipole 4G LTE antenna.

　　Polarization is a radiation characteristic that describes the spatial direction of electromagnetic field. Generally speaking, the spatial direction of the electromagnetic field vector is the polarization direction of the electromagnetic wave.

　　At a certain moment, the electromagnetic wave with unchanged spatial orientation is called a linearly polarized wave. The wave with the electric field vector direction parallel to the ground is called a horizontally polarized wave on the ground, and the wave perpendicular to the ground is called a vertically polarized wave.

　　4g GSM antennas can be divided into directional 4G and omnidirectional 4g lte antennas according to direction. 4g GSM antennas can be divided into monopolar and bipolar according to polarization mode. They can be used for 4g lte antennas in different occasions and for different purposes.

　　4g lte antennas have different types and installation environments, and there are different requirements for the design of 4g lte antenna brackets, so further research is needed.

　　With the development of global communication services, wireless mobile communications, as the main means of personal communication in the future, are highly valued by people. The elimination of co-channel interference and fading is an issue worthy of attention and research.

　　2. Five-step method for troubleshooting and rectification of 4G LTE antennas

　　1. Maintenance personnel go to the site to confirm/install the electric adjustment line, record the RRU connected to the electric adjustment line, and provide it to the background for verification;

　　2. The background network manager turns on the electric adjustment detection switch and scans and reports the electric adjustment equipment information;

　　3. According to the scanned and reported electric adjustment information, add the corresponding cell electric adjustment equipment data;

　　4. The network manager issues a correction command to confirm whether the correction is successful. For some 4G LTE antennas, the electronic downtilt scale can be observed on site during the calibration process. If the correction fails, try again;

　　5. Set and maintain the electronic downtilt degree. The scale number can be confirmed on site to see if it is consistent with the background.
