ME601 Telecommunication Modelling and Simulation
Assignment 1 :
Due: Week 7, Friday 30 August 2019 at 11:55PM
Total Marks = 75 (10% weight of total assessments)
1- Purpose of the Task:
The purpose of this assignment is to motivate students to seek to understand the fundamental principles in
the design and analysis of mobile cellular communications systems
2- Description of the assessment:
Answer all 3 questions below
QUESTION 1 (5X5 = 25 MARKS)
The mobile user equipment (UE) and the evolved Node B (eNB) specified in Table 1 are used in LTE cellular
network operating in a large city at 2.6GHz (i.e. LTE band 7: 2500 MHz–2570 MHz (UL) & 2620 – 2690
MHz (DL)]. Using the Hata’s model, calculate the following:
a) The maximum cell radius for forward link (eNB-UE) and zero fade margin (i.e. RX threshold = –
110 dBm).
b) The maximum cell radius for the reverse link (UE-eNB) for a zero fade margin (i.e. RX threshold
= -114 dBm).
c) Having calculated the forward and reverse links, is the link balanced? (justify yes or no)
d) A fade margin must be allowed for proper operation of the cellular system. State the reason for
that.
e) What is the maximum cell radius of the forward and reverse link if a fade margin of 8 dB is used?

QUESTION 2 (5X5 = 25 MARKS)
Figure 1 shows a cellular mobile telecommunication network. The cell radius is 5 km and the numbering of
one cluster only is shown.
a) Number the remainder of the cell sites for this configuration to keep the co-channel interference to
the barest minimum.
b) What is the frequency reuse distance for this configuration?
c) The eNB at a cell site can use either directional or omnidirectional antennas or both. Give reasons
for the choice of any of antenna configuration. On what basis did you make your choice?
d) How would you increase the radio coverage of a cell? List and briefly explain three methods.
Discuss the pros and cons of each choice.
e) If increasing the radio coverage of one cell resulted in an unacceptable level of co-channel
interference. How would you go about reducing the interference to achieve an acceptable network
operation?

QUESTION 3 (25 MARKS)
Assume that you have been hired to design a mobile cellular network based on LTE-Advanced (aka LTE-A)
to serve Melbourne CBD. You are expected to use CelPlanner software for your design and analysis. The
system operates in the LTE FDD Band 14 [i.e. 788 MHz – 798 MHz (uplink) and 758 MHz – 768 MHz
(downlink)]. Use carrier bandwidth of 1.4 MHz. Do some research and describe the effect of the topology
and morphology of the coverage area and state how LTE-A models the terrain using CelPlanner. Your report
should include images from CelPlanner screen and explanation of the various choices that you have made.

Comment Excellent Average Unsatisfactory
Marking
scale
80% + 50% – 80% < 50%
Students demonstrates an
excellent understanding of the
problem, and solution steps are
excellently made with reflection
on system’s design. Student also
demonstrates critical thinking
skill. Writing style is also great
looking (no typos, no
grammatical issues). There is no
copy-and-pasting in the presented
work. There are no unnecessary
digressions. Resources have been
used to demonstrate research and
initiation and are properly
referenced using IEEE
referencing style.
Students demonstrates
an average
understanding of the
problem, and solution
steps are averagely
good. Work has been
written well, but with a
few glitches.
Student demonstrates
no understanding of
the problem or/and
weak design, solution
steps are not very
correct. Work has been
written poorly or in a
rash.
