Assume that the data rate on a link if a user is using the “full bandwidth” is 100 Mbps. Assume that the bandwidth is 200 MHz. That is, each Hz of bandwidth can support 0.5 bits/s. The data rate supported by one unit of bandwidth is called the spectral efficiency and this is 0.5 bps/Hz for this link. 

Show in a figure how four users may share this bandwidth (a)in frequency and (b) in time.
