FHSS, or Frequency Hopping Spread Spectrum, is a wireless communication technique that rapidly switches the carrier frequency among many different frequency channels. This method helps to minimize interference and improve security by making it difficult for unauthorized users to intercept the signal. FHSS is commonly used in technologies like Bluetooth and some Wi-Fi systems. The primary advantage of FHSS is its resilience against jamming and eavesdropping. By hopping between frequencies, the transmission can avoid interference from other signals and maintain a stable connection. This technique is particularly useful in environments with a lot of electronic noise or when multiple devices are operating simultaneously.
