Rating:

ME503 - Telecommunication System Engineering

Assignment Description

The purpose of this assignment is to motivate students to seek to understand the fundamental systems engineering principles and their applications in telecommunication systems. The assignment has two parts: Part A and Part B.

Part A                                                                                                                                    (40 marks)

# Telecommunications Problems

Question 1: Reliability of a Parallel System                                               (5x2 marks = 10 marks)

Consider the system shown in Figure 1, which is a model of an active redundant generator at a main exchange of Telecommunication Company.

a)      Assume that the reliability of each subsystem (or component) i has the reliability of Ri.

Calculate the reliability of the overall system RS as a function of Ri.

b)      If the reliability of component i at time t is Ri(t)=e-λit, what is the reliability function of the overall system at time t?

c)      Evaluate the mean time to failure (MTTF) of the overall system as a function of λi using the reliability function in part (b).

d)      Calculate the failure rate of the overall system with exponential reliability. Hint use binomial distribution.

e)      What is the mean time before failure (MTBF) of the above system?

Question 2 Digital Microwave Radio System                                   (4x2.5 Marks = 10 marks)

A point-to-point digital microwave radio system is required by a bank to link the LANs of two of its branches at 2.048 Mbps transmission speed. The handbook delivered by the manufacturer has dimensioned the entire radio terminal with the reliability:

MTBF (mean time between failures): 100,000 hours

MTTR (mean time to repair): 2 hours (equipment only)

The radio path availability was calculated for 𝐵𝐸𝑅=10-8 and found to be 99.999% for the average worst case. The system configuration is shown in Figure 1.

a)                  Calculate the overall system availability

b)                  Draw the reliability diagram of the system

c)                  How would you increase the availability of the system required by the bank?

d)                  The useful life of the equipment shown in Figure 2 is 15 years. Calculate the reliability of the one radio terminal at the end of it life.

Question 3 High Seed Connectivity                                                                        (10 marks)

Access to the Internet has arguably become an essential service. However, the quality of the service varies widely in Australia. Multiple governments had promised (and begun to deliver) a high-speed connectivity throughout Australia via the NBN. Discuss and briefly explain the NBN technology. The discussion must be based on research findings, e.g. reference must be made of at least two journals.

Question 4 Functions of a Telecommunication Network                       (5 + 5 = 10 marks)

The functions of a telecommunication network, whether it is wired or wireless, are specified by the size of its coverage area and traffic carrying capacity. On the other hand, the performance of the network is specified by its quality of service.

a)  What limits the size of the coverage area of a telephone exchange?

b)  What limits the traffic carrying capacity of a telephone exchange?
