A hexagonal cell within a 4cell system has a radius of 1.387 km. A total of 60 channels are used within the entire system. If the load per user is 0.029 Erlang, and =1 call/hour, compute the following for an Erlang C system that has an MSBMITID % probability of a delayed call:

a) How many users per square kilometre will this system support?

b) What is the probability that a delayed call which have to wait for more than 10 seconds?

c) What is the probability that a call will be delayed for more than 10 seconds?

d) Discuss the impact of trunking in respect to the cost vs benefit analysis. Why should you take care of the grade of service (GoS) in any network?

e) Discuss why the queuing theory is important in cellular communication? Draw the birthdeath process of Markov's theory in the context of the above example for anyone system.

Note: MSBMITID is the MSB of your MITID. For example, MITID is 182832 then this number is 1 and you would need to use it as a 1% blocking probability.
