\Q2. What is the purpose of frequency re-use in the context of cellular networks?

Q3. List five ways of increasing the capacity of cellular system.

Q4. Explain the paging function of cellular system.

Q5. List and briefly define the different performance matrix that may be used to make the hand-off decisions.

Q6. Explain the difference b/w the open loop & close loop power control.

Q7. What is the difference b/w the traffic intensity and the mean rate of calls in a system?

Q8. What are the key differences b/w the 1G and 2G systems?

Q9. What are the advantages and disadvantages of using the CDMA for the cellular networks?

Q10. Explain the difference b/w hard and soft hand-off.

Q11. What are some key characteristics that distinguish 3G cellular systems from 2G cellular systems?

Ex. Assume a system of 32 cells with a cell radius of 1.6km  the total of 32 cells a total frequency bandwidth that supports 336 traffic channels and a re-use factor of N=7. If there are 32 total cells what geographic area is covered, how many channels are there per cell and what is the total no: of concurrent cells that can be handled? Repeat for a cell radius of 0.8 km and number of cells=128.
