Frequency Hopping

Frequency hopping is a method of transmitting radio signals by rapidly switching the carrier frequency among many different channels according to a predetermined pattern. This technique enhances communication security and resistance to interference because eavesdroppers or jammers must know the specific hopping sequence to intercept the message effectively. Commonly used in secure military communications and Bluetooth devices, frequency hopping ensures reliable and private data transfer by regularly changing the frequency, making it harder for unauthorized parties to detect, jam, or disrupt the signals.
