Techopedia explains Industrial, Scientific and Medical Radio Band (ISM Band)
In spite of the real purpose of ISM bands, there has been rapid growth in its use in low-power, short-range communications platforms. Bluetooth devices, cordless phones, Wi-Fi computer networks, and NFC devices all make use of ISM bands. In 1985, the U.S. Federal Communications Commission opened the ISM bands for use in mobile communications and wireless LANs. In 1997, it incorporated supplementary bands in the 5 GHz range, referred to as the Unlicensed National Information Infrastructure (U-NII). The HIPERLAN wireless LANs of Europe make use of the same 5 GHz bands known as the Broadband Radio Access Network.
