1. 2.4 GHz: The 2.4 GHz ISM band covers the frequency range from 2.400 GHz to 2.4835 GHz. It is widely used for various wireless technologies, including Wi-Fi, Bluetooth, cordless phones, ZigBee, and more.
2. 5.8 GHz: The 5.8 GHz ISM band covers the frequency range from 5.725 GHz to 5.875 GHz. It is commonly used for devices such as wireless routers, cordless phones, microwave ovens, and other industrial applications.
3. 902-928 MHz: The 902-928 MHz ISM band is commonly allocated in the United States, Canada, and some other countries. It is used for applications like wireless alarm systems, remote control systems, medical devices, and wireless sensors.
4. 2.45 GHz: Some regions allocate the 2.45 GHz ISM band, covering the frequency range from 2.45 GHz to 2.497 GHz. It is used in countries such as Europe and Japan for wireless applications, including low-power devices and sensor networks.
5. 5.15-5.35 GHz: The 5.15-5.35 GHz ISM band is reserved for indoor use and is often referred to as the U-NII (Unlicensed National Information Infrastructure) band. It is used for applications such as wireless communication systems, vehicle-to-vehicle (V2V) communication, and point-to-point links.
6. 5.47-5.725 GHz: The 5.47-5.725 GHz ISM band is another U-NII band allocated in some countries. It is used for various wireless technologies, including high-speed data communication and multimedia applications.
7. 5.725-5.850 GHz: The 5.725-5.850 GHz ISM band is commonly allocated in Europe and some other regions. It is used for applications such as automotive radar, wireless communication, and outdoor sensor networks.
It is essential to note that the specific usage and regulations for ISM bands can vary by location, and it is always recommended to consult local regulations and standards to ensure compliance when using devices within the ISM frequency ranges.
