The Solution Of Indoor Signal Coverage Of WCDMA Mobile Telecommunication Network

3G indoor coverage is an important part of the 3G construction. A number of 3G indoor coverage construction and testing have been completed in many cities to complete the construction and testing of indoor coverage. The environment for 3G indoor coverage is generally quite complex. Different projects, different objectives and priorities. In order to provide 3G network planning principles for future construction, combined with our experience in the construction of 2G indoor distribution systems and the characteristics of 3G system itself, we have developed a set of 3G (WCDMA-based) network planning principles for the construction of indoor distribution coverage systems. In order to review the reasonableness of the set of guiding principles, we organized a project improvement according to the principles, A simulation of coverage tests has been made for the improved distribution system. The focus of simulation coverage tests is to examine whether the principle could be applied.In the process of choosing coverage plan process, the article introduced environment in which each kind of supply oscillator is used and we determined the supply oscillator type according to the electromagnetic environment, the structure and height of the building and different QoS requirements subscribers give. On the comparison among the antenna feeder distribution system,the fiber distribution system, etc. it had determined coverage ways for which the place was suitable. Through a series of improvements, the article has obtained the plan which is finally used, and the install position of the antenna, the primary device, the skeleton line amplifier, etc.WCDMA system is supposed to provide users a wealth of business types (such as video telephone, multimedia, high-speed downloading, etc). high-speed means high-capacity wireless network, and also means higher quality of service and service level, which in turn directly associated with invest in the network construction. Because different user groups, different service requirements. so there is a need in the network early stages of planning a rational allocation of resources according to business needs in order to save investment, and can accelerate the speed of network construction.
