Research On The Construction Of LTE Wireless Network

With the LTE user base, rapid development of technology, the terminal business,global LTE development into the fast lane, according to the Weipu consulting released a report, LTE network investment business for three years, the world has more than 160 operators has completed the deployment of LTE networks. LTE network scale growth is rapid, the world’s 800 mobile operators in 20% has carried out the deployment of LTE networks, that LTE will usher in rapid growth stage.This paper first carries on the demand analysis,combining the characteristics of city area construction projects,the population distribution of the needs of the projece.Selection on the basis of the site,including the research base construction,indoorand outdoor facilities construction.Construction scheme proposed facilities including power supply facilities,computer room construction,lightning protection facilities construction,energy saving and emission reduction facilities construction project,Finally,in order to ensure that the project can proceed smoothly and guarantee the implementation of the projece,including the training of personnel and the construction safety management program.Analysis of the construction of the entire project according to the overall strategy ofclear requirements, this project uses the "hybrid network, synchronous deployment" strategy, share a core network, TD-LTE and LTE FDD are two kinds of wireless access network in a. The basic communication needs of users, the use of traditional CDMA mode should be implemented, bearing the basic relay. The data service isimplemented in two ways, for fixed and broadband data services using TD-LTEimplementation, the user terminal is based on Single Model(single cases of model)and the traditional EIMSI card used in parallel. For the consideration of theinterconnection network in cooperation with other communication operators. For the mobile Internet business data using the FDD-LTE model to achieve. In the actual user experience of traditional CDMA model and the hybrid network model can smoothly switch.LTE wireless network engineering to achieve coverage requirements part of the maincity of simulation, the simulation of the main scale simulation on the LTE FDD site from RSRP, SINR and so on, in order to provide reference for the construction andtesting and deployment of network. The project is divided into basic review andplanning based on the review of the two most coverage simulation,a basic reviewincluding high,azimuth and inclination angle; planning review coverage simulationmainly from the two aspects of RSRP, SINR on the LTE FDD simulation based on. The simulation of network coverage and downlink/uplink throughput functional testing using the DT testing technology. From the analysis of the technical indicators can meet the basic needs of users to test network construction standards.After completion of the project the need for border area network optimization tests to ensure the feasibility of the project, the signal strength in the boundary region within the test area, we must ensure that no signal blind spots throughout the border regionin accordance with the project requirements, ensure that the average strength is better than the national standard area signal. After testing the whole network optimization Department of network engineering to achieve the national standard andcan meet the users on the network cyber source requirements.
