How does the spread spectrum technique of frequency hopping work?

  1. If interference is detected by the receiver it will signal the transmitter to change frequencies
  2. If interference is detected by the receiver it will signal the transmitter to wait until the frequency is clear
  3. A pseudo-random binary bit stream is used to shift the phase of an RF carrier very rapidly in a particular sequence
  4. The frequency of the transmitted signal is changed very rapidly according to a particular sequence also used by the receiving station
