Discussion And Implementation Of PN Planning On Wireless Communication Network

As the third generation mobile communication system has been improved,mobile communications market competition is also increasingly fierce, all kinds ofCDMA network construction has gradually mature, but with the increase of the usersand the geographical coverage expansion, the network construction need more widely,and ensure the voice communication in the also want to give users the high quality ofthe data business, so operators network construction of planning and constructionbefore the network optimization problems became the focus.This paper according to the3G mobile communication system of technicalstandard, analyzes the CDMA mobile communication system of wireless networkcharacteristics. Deep understanding on code division multiple access, spread spectrumcommunication PN code and the specific meaning and basic concept, and on the basisof CDMA2000communication system for example to put forward planning andimplementation of PN specific methods, on the wireless network optimization PN inin the process of planning.In the process of testing for now nets, part of the covered area appears PoorCoverage, voice interrupted, through the analysis of the fault phenomena, signalingsystem to find out the fault reasons. For working parameters configuration is notreasonable phenomenon, reconfiguring the frequency search window, the PN adjacentregions list, parameters such as power stations. Combined with the actualenvironment around fault point and the test data, and adjusting the base stationantennas azimuth, dip Angle, the necessary replacement antenna gain change. Afteroptimization test again, network fault all been resolved, and various performanceindicators system is improved.The above content have got the certificate of the experiment, the hardwaresystem mainly have PC, encryption dogs, GPS controller is equipped, test mobilephones. In Windows XP operating system environment, use of zte CNT, CANsoftware realization of wireless network testing and optimization. Experimentalresults show that the planning and optimization PN in wireless network constructionand operation play an important role, and it also proves optimization of wirelessnetwork performance improvement.
