blocker Jamming Signal Attack

Jamming attacks are more serious than thought, allowing hackers to locate, intercept or overwrite data via radio. To resist wireless interference attacks, the carrier can be quickly switched between different frequencies. This is a common frequency hopping technology. The faster the frequency switching, the safer it is.

The transmitter and receiver use a pre-determined shared sequence, the signal jammer transmits data on different channels, and the packet-level frequency hopping technology hops between 80 channels, sending one data packet at a time. The frequency switching speed is not fast enough to be vulnerable to attack. It takes about 612 microseconds for the Bluetooth low energy transmitter to transmit a data packet.
