Frequency hopping meaning

In frequency hopping systems, the transmitter changes the carrier frequency. A wireless modulation method that rapidly changes the center frequency of a transmission. See spread spectrum and 802.

THIS DEFINITION IS FOR. However, for compact applications, this means inconvenient hardware. FHSS is a wireless technology that spreads signals over rapidly changing frequencies.
