- To reduce Mulitpath Fading effect which is dependent in carrier frequency
- To randomize Co-Channel Interference (CCI)
The hopping algorithm is continuously broadcast on BCCH and MS/BTS transmits TDMA frames on different hopping carriers during a call on hopping TRX. Hopping is used on TCH, SDCCH and all Packet Data channels while BCCH and common control channels are not allowed to hop. Frequency hopping types are:
- Baseband Hopping (BBH)
- Synthesizer Hopping (SFH)
- Discrete Hopping
