Frequency Hopping Spread Spectrum (FHSS) is a wireless communication technique that rapidly changes the carrier frequency among many frequency channels. This method helps to minimize interference and improve security by making it difficult for eavesdroppers to intercept the signal. By hopping between frequencies, the system can maintain a stable connection even in crowded environments. FHSS is commonly used in various applications, including Bluetooth technology and some military communications. The technique allows multiple users to share the same frequency band without causing significant interference, making it an efficient choice for wireless networks and devices.
