What is Frequency-Hopping Spread Spectrum (FHSS) primarily used for?

• A. Improving data storage efficiency
• B. Transmitting radio signals over multiple frequencies
• C. Encrypting data during transmission
• D. Boosting bandwidth in Wi-Fi networks

Answer: (B)

Frequency-Hopping Spread Spectrum (FHSS) is primarily utilized for transmitting radio signals over multiple frequencies. This technique involves rapidly switching the carrier frequency among different frequency channels, which enhances the robustness of the transmission against interference and eavesdropping. By hopping between different frequencies, FHSS makes it difficult for unauthorized users to intercept the signal and reduces the likelihood of signal degradation from competing signals and noise. This method also improves the overall reliability and security of the communication, making it suitable for environments with a lot of wireless activity. Its application can be seen in various technologies, including Bluetooth and some forms of military communications, where secure and reliable transmission is paramount.
