Introduction: LoRaWAN , renowned for its low-power, long-range wireless communication capabilities, is a cornerstone in IoT connectivity . However, real-world applications often encounter interference issues that can impede communication quality and stability. This article offers practical suggestions to tackle interference problems within LoRaWAN networks . I. Choose Appropriate Frequency Bands: LoRaWAN operates in various frequency bands, each with distinct channel numbers and bandwidths. Selecting a suitable frequency band during device deployment is crucial to avoid conflicts with other wireless devices . For instance, in Europe, the 868 MHz band is common for LoRaWAN , while in the United States, the widely used band is 915 MHz. In China, LoRaWAN typically utilizes the 470MHz to 510MHz SRD band and the 779MHz to 787MHz ISM band. Choosing the right frequency band based on regional considerations is vital. II.
