Method of increasing the communication transmission distance of the module

Method of increasing the communication transmission distance of the module:

　　 The communication transmission distance of the module is related to the following factors: antenna, receiving sensitivity, air speed, receiving and sending environment, wireless voltage and battery capacity, etc.

　　 1. Use a high-gain directional antenna. The antenna gain is one of the most important parameters of the antenna, which is very important to the operating quality of the wireless communication system. The use of high-gain antennas can increase the signal coverage or increase the strength of models within a certain range. The higher the antenna gain, the better, and the smaller the standing wave ratio, the better.

　　2. Obstacle removal. Obstacles have a relatively large impact on the transmission distance of the module. If there are metal obstacles in the use environment, such as building walls, mountains, woods, etc., the signal transmission of wireless transmission is not ideal. Therefore, we can adjust the position of the wireless module, such as offset and elevation, so that the transmission distance of the wireless module will be longer.

　　3. Increase the transmission power. Generally, the greater the power, the longer the communication distance.

　　 4. Adjust the appropriate air speed. The higher the air speed, the closer the communication distance, and the higher the packet loss rate.

　　 In addition, if you want to achieve ultra-long transmission distance, we recommend using LoRa modulation mode modules. This kind of module has strong anti-interference ability and has a strong ability to suppress the same frequency interference; secondly, it has low power consumption and can be used for a longer time in projects that require battery power. Finally, the confidentiality is high, and the possibility of being intercepted is extremely low. Typical products are like the LoRa module independently developed by Sixin. Its transmission distance is as long as 11.5km. The lora wireless transmission application can be realized only through the serial port.
