    It functions even when the device is in airplane mode, and can only be avoided by disabling Bluetooth from the device's Settings app. [1] [2] [3] The attack can cause the device to crash. [2] It also affects iOS 17.1. [4] The release of iOS 17.2 made devices more resistant to the attack, reducing the flood of popup messages. [5]

  5. 2.4 GHz radio use - Wikipedia

    en.wikipedia.org/wiki/2.4_GHz_radio_use

    Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.

  6. Frequency-hopping spread spectrum - Wikipedia

    en.wikipedia.org/wiki/Frequency-hopping_spread...

    FHSS signals are highly resistant to narrowband interference because the signal hops to a different frequency band. Signals are difficult to intercept if the frequency-hopping pattern is not known. Jamming is also difficult if the pattern is unknown; the signal can be jammed only for a single hopping period if the spreading sequence is unknown.
