This study defined the way to distribute power of forward channel and suggested a new model for prediction power in order to minimize the deterioration of call quality and performance in the CDMA mobile communication system of narrow band using 1.2288MHz of narrow band. Each change in Ec/Io was measured for the factors affecting wireless environment(e.g. the changes in power of overhead channel, the changes in a number of call channel, and the increase in interference from the additional facilities of adjacent base station or other systems) to know the influence on the wireless environment of forward link. The new way for power distribution to a base station in operation and its validity was checked by comparing before and after test.
