it was decided to add five additional channels, ( 6 f , 7 f , 8 f , 9 f , 10 f ) while keeping the frequency hopping sequence to five bands. Is it advisable to maintain frequency hopping within each of the channels ( 1 f , 2 f , 3 f , 4 f , 5 f ) and ( 6 f , 7 f , 8 f , 9 f , 10 f ), or it is better to select five channels among the bands ( 1 f , 2 f , 3 f , 4 f , 5 f , 6 f , 7 f , 8 f , 9 f , 10 f )? Explain your answer with some quantitative measures.
