1. A mobile station traveling at a speed of 60km/h transmits at 900MHz. If it receives or transmits data at a rate of 64kbps, is the channel fading slow or fast? 2. The power received at a mobile station is lognormal with a standard deviation of 8dB. Calculate the outage probability assuming the average received power is 96dBm and the threshold power is 100dBm. 3. Determine the minimum signal power for an acceptable voice quality at the base station receiver of a GSM system (bandwidth 200kHz, data rate 271kbps ). Assume the following data: Receiver noise figure =5dB, Boltzmann's constant =1.381023 Joules /K, mobile radiated power =30dBm, transmitter cable losses =3dB, base station antenna gain =16dBi, mobile antenna gain =0dBi, fade margin =10.5dB, and required Eb/N0=13.5dB. What is the maximum allowable path loss? What is the maximum cell radius in an urban area where a 1km intercept is 108dB and the path-loss exponent is 4.2
