Answer:
The wider channel bandwidth is efficient and good as it help in increasing the speed of the transmission. Due to the wider channel of the bandwidth it also lead to consuming less energy of the battery and make cost effective.
Due to the wider bandwidth, the number of clients can easily share and transfer the data in the channel and also make the transmission complete.
If the channel of the bandwidth is double then, the single transmission can easily carry more data. Hence, it also lead to double the speed of the transmission.
