A mobile is located 5 km away from a base station and uses a vertical 2/4 monopole antenna with a gain of 2.55 dB to receive cellular radio signals. The E-field at 1 km from the transmitter is measured to be 10-3 V/m. The carrier frequency used for this system is 900 MHz. (a) Find the length (m) and the effective aperture of the receiving antenna (m²) [8.33cm, 0.016m²] (b) Find the received power at the mobile using the two ray ground reflection model assuming the height of the transmitting antenna is 50 m and the receiving antenna is 1.5 m above ground.
