submission.
Question 1:
(a) Discuss the reasons why multiple antennas are sometimes
mounted at the same height on the same antenna tower.
(b) Assume that an eNodeB uses two sets of antennas which are
mounted one set above the other on the same antenna tower.
Discuss what should be the minimum vertical separation
between the two sets of antennas for proper system functioning.

Question 2
The size of Melbourne city in the Victorian State of Australia is
about 9,990 square kilometers. Assume that a
telecommunications operator called Telstra has 100% mobile
cellular coverage of entire Melbourne. Compute the maximum
number of cell sites that Telstra needs to cover the entire area if
it uses:
(a) micro-cells, each of radius 500 m.
(b) macro-cells, each of radius 20 km.
(c) Use CelPlanner® software to illustrate your design.
Assume that each cell has a hexagonal shape.
[5+5 + 10 = 20 marks]
Question 3 (40 marks)

5. A cellular system which uses microcells of radius 500 m and the
cluster size of 3 requires the minimum signal-to-interference
ratio (SIR) of 24 dB.
(a) Compute the average reuse distance D for the path loss
exponent of (i) 2 and (ii) 4.
(b) Compute the worst-case reuse distance D for path loss
exponents of (i) 2 and (ii) 4.
Assume in all cases that the CCI far outweighs all other types of
noise in the system.
[10 + 10 = 20 marks]
Question 4
Assume an operator has acquired a 20-MHz bandwidth from a
local radio frequency spectrum regulator to roll out a mobile
cellular network based on LTE-Advanced technology using a
cluster size of C=4. In LTE, the smallest unit of frequency
resource which can be allocated to one user is called a physical
resource block (RB). One RB occupies 180 kHz of frequency,
lasts 0.5 ms in time, and it is made of either twelve 15-kHz
OFDM subcarriers or twenty-four 7.5-kHz OFDM subcarriers.
The operator divides the 20 MHz into 100 RBs occupying 18
MHz. The remaining 2-MHz bandwidth is used as guard bands.
Place the traffic channels in the cells such that both the ACI
within a cluster and CCI (co-channel interference) between
clusters are minimized. Explain your cellular system design
(i.e., cell planning and frequency planning) using appropriate
diagrams.

Question 5
A cell in a mobile cellular network serves a number of users,
each of which on the average generates a single call of duration
3 minutes during the busy hour. Each blocked call is not queued
but cleared. The grade of service of the network is 2%. The
number of duplex traffic channels assigned to the cell is 21.
(a) Compute the maximum number of users that the cell can
serve at the same time if no sectoring is used.
(b) How many users can the cell serve simultaneously if the cell
is divided into:
(i) 3 sectors each covering 120o?
(ii) 6 sectors each covering 60o?
Assume that channels are shared equally among the sectors of a
given cell.
(c) Compare the trunking efficiencies of the three cases studied
above.
[5+10+5 = 20 marks]
Question 6
A mobile system serving a large city has the following
parameters:

7. Compute the largest radius that a cell in the mobile system can
be in order to keep the total link path loss within 70 dB.
Assume that as the cellular system designer, the only path loss
model available to you is the Okumura-Hata path loss model.
[20 marks]
Question 7
(a) Explain the purpose of multiple access schemes in cellular
mobile networks.
(b) Differentiate between multiplexing and multiple access
schemes as used in cellular mobile networks.
(c) Explain in detail how the multiple access schemes (MACs)
CP-OFDMA, OFDMA, SCMA, NOMA and DFT-spread OFDM
differ from each other. These are potential MACs for 5G
mobile.

Marking Criteria
The following shall be used to grade your submission.
Content Knowledge (Marks: 60% )
Ability to Communicate (Marks: 20%)

8. Academic Discourse Skills (Marks: 10%)
Basic Language Skills (Marks: 10%)
5
Student demonstrates outstanding understanding and content
knowledge beyond the scope required by the assignment task.
The system design methodology is technically sound.
The Lecturer understands the content completely; if there are
any mistakes they do not interfere with the meaning.
Referencing style is 100% in accordance with the IEEE
standards.
There is a clear logical argument, with the points well ordered
and fully supported. It responds appropriately to the question
asked. Enough relevant literature is cited to support work.
Pleasingly broad range of sentence structure and vocabulary is
used. Telecommunication terminology is used correctly.
4
Student demonstrates sound basic knowledge and understanding
of the relevant subject matter. The system design methodology
is technically fairly sound.
Lecturer understands the content, although some sections need
to be read more than once.
The answer responds more or less to the question asked. The use
of supporting evidence, illustration and argument is relevant but
not necessarily sufficient.

9. There is a good range of sentence structure and terminology
with a number of minor errors in word formation or spelling.
3
Student exhibits adequate basic knowledge of the topic area.
Lecturer mostly understands the content, despite occasional
difficulty.
A point of view is presented, but it is not always clear.
Attempts to include supporting evidence, illustration or
argument are made.
While there are noticeable language errors, these do not
significantly interfere with the lecturer understanding the
content.
2
The student’s apparent knowledge and understanding of relevant
content is limited.
Lecturer has difficulty understanding the content, although
there are signs of meaning breaking through.
The argument does not progress smoothly. Main points and
supporting material are not clearly distinguished from each
other.
The range of steps expressed correctly is limited. Errors in
terminology, grammar, word choice, word formation and
spelling cause difficulty for the marker.

10. 1
Student shows little evidence of knowing the relevant content.
The marker can hardly understand the content of the submitted
report.
The ideas or facts presented have little apparent relation to each
other or to the question asked.
Errors in sentence structure, terminology, word choice, word
forms and spelling predominate and prevent communication.
0
1. The answer is copied or substantially copied from materials
or other sources (plagiarism).
2. No relevant attempt has been made by student to solve the
questions.
