A cellular system has 100 identical cells to cover a geographical area, and a total of 280 full-duplex voice channels are available in the entire system. The system uses the frequency reuse factor of 4, and that one full-duplex channel is shared among eight different users using TDM (Time-Division Multiplexing). How many simultaneous voice calls can be supported in the entire system? Assume that an equal number of voice channels are allocated to each cell.
3. a. If 30 MHz of total spectrum is allocated for a duplex wireless cellular system and each simplex channel has 25 kHz RF bandwidth, calculate the total number of channels per cell site, if the frequency reuse factor N = 4 cell is used.

(a) A cellular network system with a cluster size of 12 is designed to operate in a propagation environment with a pass loss factor of 3.5. Verify whether the designed system can be successfully deployed for practical use if a minimum signal to co- channel interference ratio of 18 dB is required for the satisfactory performance. Assume that the interference comes from the first-tier co-channel cells in the system which at the same distance from the mobile phone. (b) If...
Let a total of 48 MHz of bandwidth be allocated to a particular FDD cellular telephone system, which uses two 36 kHz simplex channels to provide full duplex voice and control channels. Compute the number of channels available per cell if the system uses 8-cell reuse. If 1.44 MHz of the allocated spectrum is dedicated to control channels, determine an equitable distribution of control channels and voice channels in each cell.

5. Suppose that are to design a wireless network with the following constraints and properties: • Cells are arranged in a conventional hexagonal layout, with equal sized hexagons. • Each cell has an area of 1 km • The number of cells per frequency-reuse cluster may be N = 1,3, 4,7 or 12. • The path-loss exponent is a = 3.5. • The minimum acceptable SIR is 11 dB. • There are 144 available channels (i.e., 144 calls can be...
Section A (40pt). In this section you decide whether a given statement is true (T) or false (F). Place letter T within the parenthesis if the statement is true; otherwise, place F. In this section, when we mention "cellular system," we refer to those which is not a CDMA-based system. 1. Base station decides which mobile needs to handoff and manages the handoff process 2. In an FDD system, the frequency band is split into multiple frequency channels and each...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
