Third Generation Mobile Communication System Network Planning

After more than 20 year ultra conventional development, the telecommunications industry is entering the mature period. After the fast growth stagnates suddenly, the network froth bursts in abundance, the telecommunications industry has fallen into the trough as if all of a sudden. However the telecommunications industry innovation has not stopped actually, 3G, wide band, IP and so on, these technical innovations will inevitably eagerly anticipate the telecommunications industry to leap to jump onto the new stair, will enter the fast growth once more the track. Develops from the global market and the Chinese migration communication industry development looked that, we already could feel 3G's footsteps sincerely, will be able clear to describe 3G's bright future.The initial period 3G wireless network cover quality has decided the future entire network development user's speed and operation business in this network income, even whether is the entire 3G network healthy movement determining factor, therefore 3G wireless network earlier period plan promising important.WCDMA is a standard which in 3G most has represents, because WCDMA is a soft capacity and the mix operational channel, is carrying on the wireless network planning, needs to consider fully the capacity, the cover and the system disturbance mutual influence, is adding on the power control, the soft cut, softer factors and so on cut and multi-services, is the WCDMA system network planning relative 2G network system wants complex very many; Constructs the WCDMA system, the principle of equality is "a plan, divides the step the implementation". Must consider fully in the network construction initial period future the need to develop, will control in the construction adds the chain-reaction which the station will bring, then on the request wireless network equipment diversification, technical foresightedness strong, the evolution will promote smoothly simple.In view of these questions, the present paper take WCDMA as an example, mainly from the plan flow, the service model, the dissemination model and the calibration, the plot cover radius, the special place cover solution, the station site choice, the simulation, harassed the code the plan and other correlations plans several aspects to do the research, Expected forms set of integrity, detailed and the practical WCDMA wireless network planning method, and planned the GuiLin city WCDMA wireless networks according to this method union actual situation to take the reference.
