Quzhou Unicom CDMA Expansion Project Preliminary Study

With economic development, urban high-rise have emerged, resulting in a good part of the original coverage area into a weak zone coverage or blind spots; urban expansion, new development zone, College Park, and a new residential quarters covering the blind spot; At the same time, the building has also become a need to address the indoor coverage of the region. In addition a large number of users of wireless data industry's development, leading to tension in the network data resources, in order to highlight the advantages of CDMA wireless data, the current urgency to address this problem. The focus in the region to improve network coverage and network coverage and quality to achieve "quality network" of the construction requirements of the network layout is reasonable, good quality of the network.Quzhou since 2001, Unicom CDMA network construction, has gone through seven stages of the project: Phase I, Phase II, Phase III stage, the second phase of the Phase III, IV, 5, and 6. According to the preliminary analysis of the project after the network, combined with user traffic demand and changes in the depth of network coverage, marketing strategy, brand image and data services and value-added services such as the development, CDMA network coverage and capacity constraints are no longer the main users, the current CDMA expansion project relied mainly on the adjustment and optimization of existing networks to enhance network quality and improve the urban, high-speed network, expand the principle of free or low-efficiency benefits of the regional network; adjustments to optimize the network to further enhance the network There is capacity utilization in the region needs to carry out a small amount of low-cost expansion.
