915 MHz refers to a frequency within the unlicensed Industrial, Scientific, and Medical (ISM) radio bands, specifically in the range of 902–928 MHz. This band is widely used in North America for wireless communications, including IoT devices, RFID systems, and some Wi-Fi and cordless phone applications. Because it is unlicensed, it does not require special government permission to operate, making it popular for both consumer and industrial uses. In cybersecurity, devices operating on 915 MHz can be targets for wireless attacks, such as eavesdropping or jamming, so securing communications over this frequency is important.
