Method to Improve the Transmission Distance of 433MHz Wireless Module
433MHz wireless modules are commonly used in our country, and are generally used in security systems, access control systems and other fields. After many customers bought the module, the transmission distance of the wireless module was unsatisfactory due to the use environment, weather and other factors. So, how should the transmission distance of the 433MHz wireless module be improved?
The transmission distance of the wireless module is related to factors such as the frequency and amplitude of the modulation signal, antenna, receiving sensitivity, wireless voltage and battery capacity, and the receiving and sending environment. Shenzhen Siwei Wireless Recommendation: In general, the following four methods can be used to increase the transmission distance of the wireless module.
1. Use matching high gain directional antennas.
2. Adjust the appropriate transmission frequency.
3. Increase the transmission power.
4. Improve the receiving sensitivity of the module.
Shenzhen G-NiceRF Wireless Technology Co., Ltd. specializes in the research and development and production of high-power, industrial-grade, long-distance wireless modules. The wireless modules produced by our company have a variety of frequency options, 433MHz, 490MHz, 868MHz, 915MHz, and the modules have long-distance and small size. , Good quality, affordable price and other characteristics, the transmission distance ranges from 100 meters to 5000 meters. The user does not need to write a setting program in use, which can reduce the development difficulty and shorten the product development cycle.
