(a) increases linearly to infinity
(b) increases logarithmically to infinity
(c) Increases, and then approaches to a constant (d) decreases, and then approaches to a constant
4. (Slide 11) Sketch the channel capacity C (bits/sec) vs bandwidth W (Hz) plot when other parameters are fixed.
5. What is the key wireless technology used for the 4G wireless mobile net- works?
6. What does MIMO stand for? What is a key difference between MIMO and Massive MIMO implementations?
