WebFHSS - Frequency Hopping Spread Spectrum. In 802.11 standards, three different modulation/transmission methods are used to transmit wireless signals: 1) Frequency … WebIn a FHSS systems the data is sent using a transmission frequency that moves from one frequency to another in a "hop" sequence. Hence, a hopping pattern can be observed in the spectrum. FHSS is for instance used by Bluetooth. Bluetooth hoppes 1600 times per second between the 79 available channels.

WebFHSS is a wireless technology that spreads signals over rapidly changing frequencies. Each available frequency band is divided into subfrequencies, and signals rapidly change, or “hop,” among these subfrequency bands in a pre-determined order. This not only makes it highly resistant to interference, but difficult to intercept. WebThe transmission scheme (FHSS) provides another level of security in itself. Instead of transmitting over one frequency within the 2.4 GHz band, Bluetooth radios use a fast frequency-hopping spread spectrum (FHSS) technique, allowing only synchronized receivers to access the transmitted data.
