ISM band facts for kids
The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical (ISM) purposes other than telecommunications.
The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency, so these devices are limited to certain bands of frequencies.
Even though they are supposed to be reserved for ISM purposes in recent years the fastest-growing use of these bands has been for short-range, low power wireless communications systems.
Cordless phones, Bluetooth devices, near field communication (NFC) devices, garage door openers, baby monitors and wireless computer networks (Wi-Fi) may all use the ISM frequencies, although these low power transmitters are not considered to be ISM devices.
