| Abstract: | With the interference factor added into the power control equations, a calculation method has been derived, which demonstrates the relationship between the outage probability, the sensitivity of the base station receiver, the maximum transmission power of the mobile station, the expectation of signal to interference ratio(SIR), the coverage radius and the capacity of the cell. Some calculated results of the coverage radius and the cell capacity were shown for given frequency of 2 GHz, different data rates and awide bandwidth. |
