Learning Outcome 1: Design, analyse and evaluate wireless mobile communication systems;

Learning Outcome 2: Research and analyse recent developments, and relate them to the principles of mobile network design and network management;

Learning Outcome 3: Apply engineering techniques, tools and resources to plan and model cellular networks;

Assignment 1A

Figure 1 illustrates the frequency plan of a cellular mobile telecommunication network. Assume that the network is being designed to cover 90% of Canberra city in ACT of Australia with land size of about 814.2 square kilometers. Assume that the cell radius is 5km. As shown in the figure, sets of frequencies have been allocated to one of clusters in the network.

a) Complete the numbering of the cell sites for this configuration to keep the co- channel interference to the barest minimum.
b) What cluster size is used in the system under discussion?
c) How many cells of the same radius are needed to achieve the required coverage? Make any needed realistic assumptions and clearly state them.
d) What is the frequency reuse distance for this configuration? Justify your answer.
e) The 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?
f) Concisely discuss three methods that can be used to increase the capacity of a mobile cellular communications system. Discuss the pros and cons of each method.
g) 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 2

Multiuser communications systems cannot operate without multiple access control (MAC) schemes. The MAC schemes used differ across wireless technologies. Currently, the dominant mobile cellular technology is 4G/LTE and LTE-A. Fifth generation (5G) technologies are still being installed and operate in some countries. Research is underway on 6G mobile cellular technologies. Your task in this question is to research to find one of the MAC schemes being investigated for possible adoption in 6G. You must fulfill the following criteria in your submission:

1) Cite at least 2 journal papers on the chosen MAC scheme.
2) Summarize your research findings in a maximum of 4 A4 pages using 11-point font size.
3) Clearly state why your chosen MAC scheme is interesting by indicating its strengths and weaknesses in comparison to other proposals.
4) State the competing MAC schemes to your chosen one.
5) Submitted report must be of professional standard (e.g. without typos, good English grammar, well formatted).

Question 3

Assume that you have been hired to design a mobile cellular network based on LTE-Advanced (aka LTE-A) to serve Mernda (VIC3754) suburb in Victoria state of Australia. You are expected to use CelPlanner software for your design and analysis. The system operates in the LTE FDD

Band 17 [LTE band 17: 704 - 748 MHz (UL) and 758 - 803 MHz (DL)]. Assume system bandwidth of 5 MHz. Your answer should include the following.

• Research on the effect of topography and morphology for designing mobile cellular network for the coverage area.
• State how LTE-A with above frequency band and bandwidth can be designed for coverage area using CelPlanner.

Your report should include images from CelPlanner screen and explanation of the various choices that you have made in your network design.
