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, to prevent eavesdropping, and to enable code-division multiple access (CDMA) communic… WebbWhat is frequency hopping: The change of RF carrier frequency during the transmission of information is known as frequency hopping. In GSM RF carrier is changed every 4.615ms. This gives 217 hopes per second. This means in GSM, RF carrier frequency is changed in each of the bursts transmission. smart card avanti west coast
