ISM Bands

ISM bands (Industrial, Scientific, and Medical bands) are specific radio frequencies reserved internationally for wireless devices that don’t require a license to operate. These unlicensed bands enable various technologies like Wi-Fi, Bluetooth, cordless phones, and medical equipment to communicate wirelessly without interfering with licensed communications. They are shared spaces, meaning multiple devices can operate within these frequencies simultaneously, often using different methods to avoid interference. ISM bands are essential for many contemporary wireless applications, providing accessible, cost-effective means for short-range data transmission and wireless connectivity.
