Frequency hopping mode
WebFHSS technology synchronizes the changing frequency of both the transmitter and receiver (using a narrowband carrier) to, in effect, produce a single transmission … 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. FHSS is used to avoid interference, … See more Military Spread-spectrum signals are highly resistant to deliberate jamming unless the adversary has knowledge of the frequency-hopping pattern. Military radios generate the … See more The overall bandwidth required for frequency hopping is much wider than that required to transmit the same information using only one carrier frequency. But because transmission occurs only on a small portion of this bandwidth at any given time, the … See more • Dynamic frequency hopping • List of multiple discoveries • Maximum length sequence • Orthogonal frequency-division multiplexing See more In 1899 Guglielmo Marconi experimented with frequency-selective reception in an attempt to minimise interference.
