What are the channels of Zigbee?
Last Updated on：2025-09-10 09:21:52
16 channels, channel spacing 5MHz, numbered CH11-CH26, channel center frequency list: 2405MHz, 2410MHz, 2415MHz, ......, 2475MHz, 2480MHz, etc., with an actual 99% occupied bandwidth of about 3MHz. There is an overlap with Wi-Fi channel distribution, and after overlapping, there will be significant interference with each other. In China, the commonly used Wi-Fi channels are 1, 6, 11, so the preferred Zigbee channels are 11, 15, 20, 25, 26. The module will automatically select the optimal channel based on the environment.
