QUESTION 1

The radio signal propagation path loss is given by

P_R/P_T = G_TG_R(λ/4Πd)²

where

- λ is the wavelength of signal, measured in meters
- GT and GR are the gains of the transmit and receive antennas
- d is the distance between the signal's transmitter and receiver

Assume that the mobile station's antenna gain is 0 dBd, and the base station gain is 11 dBd (same for uplink and downlink). For a downlink communication, if the base station is transmitting at 35 dBm, calculate the received power at a mobile station at a frequency of 850MHz and at a distance of 10km? Assume that only free-space loss applies.

QUESTION 2

Assume that you have been hired to design a mobile cellular network based on LTE- Advanced (LTE-A) to serve Melbourne CBD. You are expected to use the CellDesigner software developed by CellPlanner Technologies Ltd 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 CellDesigner (formerly known as CellPlanner). Your report should include images from CellDesigner (formerly known as CellPlanner) screen and explanation of the various choices that you have made. Please provide references of your research.

QUESTION 3

Figure 1 shows a cellular mobile telecommunication network. The cell radius is 5 km and the numbering of only one cluster is shown in Figure 1.

a) What is the frequency reuse distance for this configuration?

b) Number the remainder of the cell sites for this configuration to keep the co- channel interference to the barest minimum.

c) The eNB at a cell site can use either directional or omnidirectional antennas or both. Give reasons for the choice of any of these antenna configurations. 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?

Marking Rubrics: Comment Excellent Average Unsatisfactory (Fail) Marks 6.1 - 10% 4.1% - 6 < 4% 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.
