Frequency-hopping spread spectrum (FHSS) transmission is the repeated switching of the carrier frequency during radio transmission to reduce interference and avoid interception. FHSS is useful to counter eavesdropping, as well as to obstruct the frequency jamming of telecommunications and to enable code-division multiple access communications.

- Dispelling The IIoT Myths Around FHSS
Frequency-hopping spread spectrum ( FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver.
El espectro ensanchado por salto de frecuencia (del inglés Frequency Hopping Spread Spectrum o FHSS) es una técnica de modulación en espectro ensanchado en el que la señal se emite sobre una serie de radiofrecuencias aparentemente aleatorias, saltando de frecuencia en frecuencia sincrónicamente con el transmisor.

Introduction/purpose: e frequency hopping spread spectrum (FH-SS) technique assumes the carrier generated by the syntesizer to hop from frequency to frequency over a wide bandwidth, according to a pseudonoise code sequence defined by the code sequence generator. e article presents the history, principles and applications of the FH-SS technique.
Learn how frequency hopping works and how it can improve the performance of communications in jammed, multiple-access, or fading channels. See examples, diagrams, and equations for different scenarios and modulation schemes.
