However, when receiving the base station signal, the product is easily affected by external factors, and the quality of the coverage effect is directly determined by the quality of the external information source. Therefore, during specific construction and installation, construction personnel are required to carefully and carefully select the position of the receiving antenna to ensure that the receiving antenna receives signals as good as possible, the process is time-consuming and labor-consuming, the position and the direction of the antenna are basically fixed and unchanged after the position of the receiving antenna is determined, and if an external information source is changed, the receiving antenna cannot be adjusted, so that the covering effect is greatly reduced. Similarly, the position of the coverage antenna in the coverage area is also fixed, if the usage of the coverage area changes, the traffic volume also changes, the coverage antenna cannot move, and the phenomena that the coverage effect of the area requiring coverage effect is not good and the area equipment without coverage requirement normally operates are easily caused. The customer complaint amount is increased, the maintenance cost is increased, and the original characteristics and advantages of the repeater can not be embodied.

and S3, the MCU disconnects the coverage antennas without uplink signals according to the uplink signal strength of all the coverage antennas.
The specific method of S2 is as follows:
the radio frequency switches of the receiving antennas are IN the initial states of RF IN 1 and RF IN3, and receive the two paths of signals, and RF IN2 and RF IN4 are IN the disconnection state;
starting to search the network, and acquiring and recording multiple sets of RSRP and SINR of signals received by RF IN 1 and RF IN3 by the MCU;

The stability of equipment is improved, and the maintenance cost is reduced.
The method of the invention leads the signal received by one receiving antenna to be transmitted into the equipment, and the MCU starts to read and store the intensity and the signal-to-noise ratio of the received signal. After the recording is finished, the radio frequency switch is switched to the other side, the other receiving antenna starts to receive signals and transmits the signals to the equipment, and the MCU reads and ensures the strength and the signal-to-noise ratio of the signals received at this time. The MCU compares the data obtained twice, and takes the antenna to which the group of data with better average value belongs as a receiving antenna, so as to ensure that the received signal is relatively best when the MCU works. The coverage area also adopts two groups of coverage antennas which are respectively placed in the areas needing to be covered, the radio frequency switch is continuously switched by the MCU before the uplink signal is detected, when the uplink signal is detected at any port, the switch is switched to the corresponding port, the smooth path is kept, and the problem of poor coverage in the application process of the repeater equipment is solved.
