| With the development of internet technology, the traditional Ethernet wired broadband technology is more and more unable to meet the main demand for access to information.Mobile broadband technology has laid a solid technical foundation for integration of mobile broadband and broadband wireless process for the production of LTE. On the other hand, with the rapid development of networks communication technology, internet technology integration, communication industry value chain from the package to open, the future of communication not only between people and people, but also exists in the people and things, things and things, wireless communication demand explosive laid the foundation for the market for LTE generation. After discussion, the formulation of standards, standards of large-scale test network stage, large-scale commercial LTE is already mature. The spirit comes from practice, in the service of the principles of practice, this paper set up the antenna in the practical work such as unreasonable, excessive workload optimization problem to carry on the research analysis, put forward specific solutions and software implementation, and achieved certain results.The first is the theory of angle model is modified, establishing suitable Inclination under the experience model of the actual environment, base station high, the coverage radius of the original angle theory model in consideration of the model, taking into account environmental openness impact of wireless signal propagation, obviously improves the precision of angle planning.The second is to realize the automatic programming function of inclination angle by using software technique. Tilt planning was originally experience form method, according to the station from the station manually set, high dip angle, the scheme of low efficiency, big error. In this thesis, to determine the base station coverage radius using Tyson polygons by using software technique, and then determine the inclination angle. From original data input to output programming angle, the entire process by the computer program to implement step by step, completely changes the current antenna inclination depending on experience value set in the status quo, better theoretical and practical combination of the two. This software has completely changed the current antenna inclination depending on experience value set status. The software has obvious effect in the aspect of engineering construction and site optimization:1. reduce engineering installation errorAccording to the construction situation of LTE of No.1 period, there are two prominent problems during the antenna installation process:the first is the antenna model is wrong, the main reason for this problem is to estimate the cell coverage radius deviation caused by excessive. The second is the antenna angle setting deviation is too large, the main reason for this phenomenon is the original value inclination of planning is not clear. This software can avoid the above two kinds of circumstances, on the basis of the accurate calculation of coverage radius, station spacing with clear information guidance.2. improve the optimization efficiency, speed up the optimization processBecause the setting on the antenna inclination of "one-step", devices can enter the fine optimization stage directly, quickly crossed the "coarse optimization" stage. Based on past experience,1-2 months after the completion of the installation of equipment for a wide range of antenna adjustment time, the software can greatly shorten the stage; set in place the premise in antenna angle, we can put more manpower, centralized to fine optimization up, it must can do fine adjustment more, network quality will be better.After practice verification, the software is used to reduce the number of construction after the "coarse optimization" time, save the net expenditure, can put the quality of network optimization better in a shorter period of time,the software has the very good application prospect. |
