Problem:
(a) Compare the different MAC schemes, namely FDMA, SDMA, TDMA and CDMA.
(b) Describe with help of diagrams the different phenomena involved in multipath propagation.
(c) Draw and explain the functions of the main components in a cellular network.
(d) What is difference between a control channel and a data channel. Describe how the control channel can be more effective for communications at time of natural disaster.
(e)
i. Describe how channel re-use and frequency re-use will increase the number of users in a cellular network.
ii. State another solution that may increase the number of users in a cell, is it cheaper than the 2 previous solutions mentioned in i?
