The 2.4 GHz ISM band is a portion of the radio spectrum, defined by the International Telecommunication Union's (ITU) Radio Regulations, for Industrial, Scientific and Medical (ISM) purposes. This band, specifically ranging from 2400 to 2500 MHz, is globally available for unlicensed use, making it a popular choice for short-range wireless communications such as Wi-Fi, Bluetooth, and cordless telephones. However, due to its unlicensed nature, devices operating in this band must tolerate potential interference from other devices sharing the same frequency range.
