1) What are the various ways to improve coverage and capacity? Compare them.
2) Write Short notes on Frequency reuse, Handoff , Trunking Theory etc.
3) What happens to the D/R ratio in cell splitting technique?
4) Why D/R ratio in cell sectoring and microcell zone concept decreases ?
5) A person moves from cell A to B and then to C with a 1G mobile phone which is not currently in use. How many time will Hand off occur?
6) If a person moves along a irregular terrain (hilly region and plateaus) which are part of the same cell, are there any chances of Hand offs?
7) The minimum detectable signal level for a mobile station is -90 dBm to -100 dBm. Specify these levels in mWs.
8) Specify a coverage capacity improvement technique in which the increase in capacity is more than double.
9) What will happen if the margin between minimum detectable signal and handoff threshold is large.
10) What will happen if the margin between minimum detectable signal and handoff threshold is small.
11) Assuming that the size of the cells and the total number of available channels are fixed.Increasing the cluster size improves the C/I and at the same time, increases Erlang capacity. This statement is true or false?
12) In an equitable distributed cell, there are 10 channels. The total traffic carried by the cell currently is 5 Erlangs. What is the load carried by one channel ?
