Using average cell sites which have the following characteristics: Handset Transmitter Power: 23 dBm

Base Station Height: 30 m

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 like400 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 manycells are required using Cost-231 model

c) If the frequency is increased to 2500 MHz, and assuming that Cost-231 still holds, how manycells are required for the same coverage.

d) If you change the coverage criteria to 75% cell edge, 90% cell what happens to the cell counte) Using the base assumptions, what would the cell count be if you were only trying to providevoice (13 kbps) and 64 kbps data?
