The Planning And Designing Of LTE Hybrid Network Project

With the development of mobile communications,the network data throughput it increases rapidly,which may leads to network congestion and a drop in thr-oughput performance,and causes a negative effect to user experience as well.The network planning directly influences the quality of network,a reasonable network planning can improve the capicity and expand the signal coverage,and then improve the performance of network.The routes of LTE network technology are divided diffently into TD-LTE and FD-LTE according to the difference of wireless access technology.The technology and signaling of them have more similarities and are universal,which prepare the ground for the integration of two techniques.The LTE hybrid network allows the two modes to be complementary,solves the problem of insufficency in coverage and capacity,as well as take a good use of spectrum resources.This paper studies and explore the LTE hybrid network planning in city Z,which simulated and verified through APC simulation software.At the same time,the wireless signal propagation prediction in complicated scenes was analyzed,and then put forward the corresponding propagation model to improve accuracy.The main process are as follow.1.Analysis of present network.After analyzing the covering scale and bussiness volume of present network,we make a decision to upgrade the network in order to improve the worse coverage quality and lack of thr-oughput.2.Networking design.Combined with the features of TD-LTE and FD-LTE,design principles and targets aiming at those problems,as well a detailed planning of the covering scale?capicity and site setting.3.Network simulation.Simulate the designed network of pre-planning and analyze the results,including RSRP,the average and edge throughput of a cell.And then evaluate the performance of pre-planning,adjust pre-planning appropriately...
