Consider a mobile system at 900 MHz carrier frequency, and with 25-kHz bandwidth, that is affected by thermal noise (noise temp Te = 300k). Antenna gains of Tx and Rx sides are 8dB and -2dB respectively. Cable loss at Tx is 2dB. The noise figure at Rx is 7dB. The required operating SNR is 18dB and desired range of coverage is 2km. The break point is at 10dB up to which the path loss is given by [ ] , beyond that point the path loss exponent is 3.8, and the fading margin is 10dB. What is the minimum Tx power required?

Consider a mobile system at 900 MHz carrier frequency, and with 25-kHz bandwidth,  that is affected by thermal noise (noise temp Te = 300k). Antenna gains of Tx and Rx  sides are 8dB and -2dB respectively. Cable loss at Tx is 2dB. The noise figure at Rx is  7dB. The required operating SNR is 18dB and desired range of coverage is 2km. The  break point is at 10dB up to which the path loss is given by [  ] , beyond that point the  path loss exponent is 3.8, and the fading margin is 10dB. What is the minimum Tx power  required?
