The number of the subseribers has been increasing raPidly,and the research of new wireless services has been made in recent years.How to use the limited resource effectively and to imProve system caPacity has been the pivotal matter of the third generation wireless communieation. Wireless network Planning is an important Procedure in 3G network. 3G network is now extensively used in a lot of countries,at the same time,China has construeted many testing network. More than seventy Percent 3G traffic come from indoor environment ; the construction of indoor contribution system can imProve the coverage,quality and capacity effectively . Indoor coverage analyze is the most significant factor in construetion of 3G network.
It raise several key issues in the WCDMA network design of indoor distributed communieation system and get some useful conclusions for the engineering. Finally, the actual construction of a comprehensive program to practice.
