WCDMA Network Planning For Tianjin Unicom

WCDMA is one of the third generation mobile communication key standards .Comparing with GSM technology, WCDMA system brings a essential improvement of spectrum ultilization and bearer services and can provide rich multimedia services for subscribers. Nevertheless, when 3G is introduced, network planning will experience a significant change; how to perform 3G network planning will be one of the most important tasks for the operators. China Unicom, owning a huge 2G GSM network, need to consider both the service requirements for 3G and the existing resources in its 2G network; thus, it could succeed in meeting customers' requirements and operation requirements as well as taking the advantages of 2G resources and reducing operation expenses.This article sets out from the developing history of mobile communication, briefly introduced each technological characteristic and their business characteristic from the first generation to the third generation mobile communication. Then it has analyzed the WCDMA's key technology with emphasis. The text will expatiate on the difference of network planning between WCDMA and GSM, and the challenge of WCDMA network planning will face with. Then author will analysis the project procedure and attentive matters in WCDMA network planning, elaborated the total programming step of the WCDMA network, analyze the purpose, meaning of the WCDMA network programming and request. The programming that analyzed the WCDMA network is divided into two parts: the planning of core nerwork, radio network. This paper confirms WCDMA market positioning, market and network development strategy for Tianjin Unicom, based on competition environment of WCDMA development and SWOT analysis.And then, based on the qualitative forecast of 3G market and service and Tianjin Unicom's specific scenario, this paper brings forward pre-layout plan of Tian Jin urban area.
