Using average cell sites which have the following characteristics: Handset Transmitter Power: 23 dBm Base Station Height: 30 nm Handset User height: 1.5 m Base Station Antenna gain: 14 dBd Handset Antenna Gain: 0 dBi Frequency: 1960 MHz. Morphology: Euro Cost Suburban Outside Shadowing standard deviation: 10 dB Building Penetration Margin: 10 dB (suburban) Building Penetration standard deviation: 8 dB Coverage Criteria 90%cell edge/95% cell a) Calculate the required signal level assuming you are reverse link limited, and that you would like 400 kbps minimum uplink speed, and that this requires 7 dB Signal to noise ratio. b) Assume that you must cover 900 square km. For this set of assumptions determine how many cells are required using Cost-231 model Using average cell sites which have the following characteristics: Handset Transmitter Power: 23 dBm Base Station Height: 30 nm Handset User height: 1.5 m Base Station Antenna gain: 14 dBd Handset Antenna Gain: 0 dBi Frequency: 1960 MHz.
