Due: Monday, 8 September 2014, 9:40 AM

A city has a population of 3 million people that are evenly distributed over an area of 1000 km2. We know that a percentage of the population is subscribed to a cellular system. Assume that the cellular system is an  Erlang B system with a total band of 14 MHz and full duplex channel bandwidth of 40 kHz and covers the city using hexagonal cells with radius 2 km and a cluster size of 7 cells. Assume that each user makes 1 call each 2 hours with average call duration of 1 minute and the desired probability of call blocking is 0.005. Find:

1)    The total number of cells in the system

2)    The number of channels per cell

3)    The total number of channels in the system

4)    Traffic intensity per cell

5)    Maximum carried traffic for the whole system

6)    The total number of users who can use the system

7)    Percentage of Population of the city who can subscribe to the cellular service

8)    The theoretical maximum number of users who can be served at any time.
