Guard Band :
It is frequency range which separates the two frequency range.
It is used to avoid interference which decreases loss of information content.
It is generally used in Frequency Division Multiplexing Access (FDMA).
Due to guard band channel bandwidth increases which is undesirable.
It is used for both wired and wireless communication.
Guard Time:
It is used to prevent overlapping transmissions or other types of interference between different transmissions.in TDMA
Frequency Hopping:
It is a technique for sending radio signals that involves quickly switching the carrier frequency among a wide range of unique frequencies. FHSS is used to avoid interference, to prevent eavesdropping, and to enable (CDMA) communications.
Onboard Switching:
SDMA provides onboard switching techniques, which, in turn, enhance channel capacity.
