Which band is designated for use by the industrial, scientific, and medical communities?

The Industrial, Scientific, and Medical (ISM) band is specifically set aside by regulatory authorities for non-communication purposes, allowing devices used in these sectors to operate without needing a specific license. This includes applications like microwave ovens, medical equipment, and various industrial sensors. The frequencies allocated for the ISM band are generally in the range of 900 MHz to 2.4 GHz, which are useful for both short-range and wide-ranging applications.

Choosing this band allows various technologies to coexist without interfering with licensed communication services, while also enabling innovation across different fields. The regulations ensure that devices operate within specific power limits to minimize interference with communication systems, further validating the purpose of the ISM band as a designated space for unlicensed use by the industrial, scientific, and medical communities.
