Frequency Hopping Spread Spectrum

Frequency Hopping Spread Spectrum (FHSS) is a method of transmitting radio signals by rapidly switching the carrier frequency among many different channels within a broad frequency band during communication. This technique makes the signal more secure and less susceptible to interference, as unauthorized listeners or jammers cannot easily follow or disrupt the communication because they would need to know the hopping pattern. FHSS is commonly used in wireless technologies like Bluetooth and military communications to improve reliability, security, and resistance to interference in crowded or hostile radio environments.
