Wcdma Wireless Link Coverage Research

WCDMA had been developed as R4, R5, R6 and the subsequent R7 version from R99 version, and 3GPP had supplied the detailed transit scheme for them all. Along with construction and development of 3G network, the wireless link cover analysis based on WCDMA will be the famous project research topic.This article analized the basic agreement of WCDMA primarily. In accrodance with the development of different period of the agreement, made the comparison among the different WCDMA versions, and then brought forward the two problems affected WCDMA wireless link cover, and got the relavant conclusion and improved suggestions according to the actual appliance.Made an indepth research of WCDMA wireless transimisson on the foundation of relevant agreement analysis. Start from the analysis of basic wireless transmission modle, then to the text method and process of WCDMA wireless transmission modle applied in commercial circumstance gradually,. Analized the correct method and standard of wireless transimisson modle at last and supplied the correct method and wireless transmission modle suited to WCDMA under the acutual condition.Finally, put an emphasis on the research on WCDMA network cover and capacity. In accordance with the essential difference between WCDMA and the traditional GSM network, made the research of covered characters of wireless link sides from upsize and downsize, analyzied the affect on system capacity by wireless link cover, made the pilot cover calculation of WCDMA and brought forward the example applied in actual network of WCDMA and the guide standard applied in practical appliance.
