I raise several key issues in the WCDMA network design of indoor distributed communication system and get some useful conclusions for the engineering.The paper has 6 parts.The first part presents the necessity of the construction of integrated indoor coverage system and raises 3 key issues what must be solved in the engineering, at last the paper shows how the 3 key issues affect the construction.The second part of the paper classifies the WCDMA indoor coverage system and shows all the parts consisting of the network.The third chapter describes the interfere between the multiple communication systems and give the causes resulting in it. After it the paper gives us some measures to avoid them. At last the paper focuses on the application of the un-passive apparatus in the system.The fourth chapter introduces several forecast models used in indoor coverage network plan and tell us the principle, function and flow of model-adjusting in indoor network plan and give us the judge criterion. The paper raises a model-adjusting arithmetic validated in the actual engineering and shows the statistics got by this arithmetic at last proves it is feasible.The fifth chapter mainly completes the emulation of the WCDMA cell capability in indoor environment under the single service and multiple services condition and gives some useful conclusions to practical works.The last chapter introduces two new technologies be about to be used in indoor WCDMA network.
