Question 1Question 1 (10 marks) The mobile radio base station and mobile station specified in Table.1 below are used in a 1000 MHz cellular network operating in a large city. Using Hata’s model, calculate the following: ⦁ The maximum cell radius for forward link (BS-MS) and zero fade margin (i.e. Rx threshold = -112 dBm). ⦁ The maximum cell radius for the reverse link (MS-BS) for a zero fade margin (i.e. Rx threshold = -115 dBm). ⦁ Having calculated the forward and reverse links, is the link balanced? (justify yes or no) ⦁ A fade margin must be allowed for proper operation. State the reason for that. ⦁ What is the maximum cell radius of the forward and reverse link if a fade margin of 10 dB applies? BASE STATION (BS): Frequency band Transmitter power Receiver threshold Antenna gain Antenna height Feeder loss (transmitter to antenna) 1000 MHz 55 Watts -115 dBm 12 dBd 60 m 2 dB MOBILE STATION (MS): Transmitter power Receiver threshold Antenna gain Antenna height 1 Watt -112 dBm 1dBd 1.5 m Table 1 Question 2 (5 Marks) Assume a transmitter (Tx) and receiver (Rx) are positioned as Figure.1. ⦁ Calculate the path loss and the power receive signal with a unit gain. ⦁ Re-calculate the power received if the antennas with gain are now transmit at 1dBi and receive at 2dBi Figure. 1 Question 3 (5 Marks) A cellular mobile phone is generally only 2m above the ground, and an average distance of 5km from the base station and must maintain a path loss of 150dB or less. What is the height of the base station antenna? Assume free space conditions.
