1. Apply Hata model: (15 Marks) (CLO2-PLO2-C4) a) A Mobile station is moving with the velocity of 60 km/h away from a base station from a point ‘A’ at 5 km distance from the BS. The mobile system is using 250 MHz carrier frequency. At ‘A’, the MS experienced a path loss of 140 dB if the MS antenna height is 2 m, what is the height of the BS antenna? If the system allows another 25 dB additional path loss, find out the cell radius and the time the car would take to cross the cell boundary. b) If we are considering suburban area and rural area, evaluate the path loss respectively
