What type of frequencies does the ISM band serve?

The ISM band serves primarily the industrial, scientific, and medical communities. This frequency band is designated by the International Telecommunication Union for the purpose of allowing devices from these fields to operate without the need for a license. It was created to facilitate research and development in areas that benefit society, such as medical equipment and various scientific applications.

The ISM band typically operates on frequencies that are used for short-range communication and does not have restrictions on the types of devices that can use it, provided they follow specific technical standards to avoid interference. This aspect makes it an ideal choice for devices that require unlicensed access for various applications, such as RFID systems in industrial settings or wireless medical monitoring devices.

While telecommunication companies, government surveillance, and consumer electronics may utilize other frequency bands, they do not specifically pertain to the primary purpose of the ISM band, which is focused on fostering innovation and efficiency in industrial, scientific, and medical domains. This distinction is key to understanding why the ISM band is tailored specifically to support those sectors.
