Reserch On WCDMA Wireless Network Planning Principle And Approach

WCDMA is a leading technical system of 3G. Combining voice traffic withvarious speed data service, WCDMA wireless network planning become verycomplicated, together with the technical characteristic of WCDMA. This article describes the composition of WCDMA, the logical structure, keytechnique, analyses the influencing factor of WCDMA in detail, for example, softcapacity, power control, soft handover, unsymmetrical traffic. The article discusses WCDMA wireless network planning method, in order toreach the organic balance of coverage, capacity, quality, building cost. It devises theWCDMA network orientation, principle, the continual development strategy. Theplanning methods of capacity and coverage are discussed in detail. The flow andarithmetic of capacity and coverage are given in article. Because WCDMA needs tosupply voice and data service, Campell traffic concept is introduced to measure themixed service. Campell model is build to calculate mixed traffic. At last, the planningsoftware-Enterprise of AIRCOM is used to plan and emulate WCDMA wirelessnetwork.
