1.      If a total of 33MHz of bandwidth is allocated to a particular FDD cellular telephone system which uses two 25 kHz simplex channels to provide full duplex voice and control channels, compute the number of channels available per cell if a system uses (a) four-cell reuse, (b) seven-cell reuse and (c) 12-cell reuse. If 1 MHz of the allocated spectrum is dedicated to control channels, determine an equitable distribution of control channels and voice channels in each cell for the three systems.

2.      Compare fixed and dynamic channel assignment strategies in mobile wireless cellular systems.

3.      Explain the system-generated cellular interference in cellular systems.

4.      Define handover. What are the types of handover in cellular networks.

5.      How bluetooth piconet and scatternets are formed?

6.      Elaborate similarities and differences between wifi and bluetooth.

7.      Draw and explain the layers in Bluetooth protocol.

8.      What are the different baseband states of a Bluetooth device?

9.      List the components of GSM architecture. What is the role of BSC and BTS?

10.   A mobile phone user has travelled from Chennai to Nanded for 3 days, which handover will take place and how? How mobile user gets authenticated in Nanded?

11.  Give the comparison between 2G, 3G and 4G systems.

12.  Define MIMO. What are the advantages of MIMO in wireless networks?

13.  Enlist the components and their functions of LTE.

14.  Which are the additional components in LTE architecture not present in 3G? Why
