China has several ISM (Industrial, Scientific, and Medical) bands available for low-power, short-range devices. The primary bands are:

• 470-510 MHz: This is the main band designated for LoRaWAN and other LPWAN technologies in China.
• 779-787 MHz: Another band available for short-range devices.
• 920-925 MHz: This band is also used, though it's narrower than in other regions.
• 433.05-434.79 MHz: The standard 433 MHz ISM band.
• 2.4 GHz: The global 2.4 GHz band is available.
• 5.8 GHz: The global 5.8 GHz band is also available.

For LoRaWAN applications, the 470-510 MHz band is the most significant and widely deployed in China.
