Software Indicators And Performance Analysis Of The Air Interface RF Testing System For TDD-LTE BTS

With the increasing development of mobile calls, mobile phone network is rapidlydeveloping to4G, TDD-LTE4G mobile network as the most critical core technologywhich led to the rapid development of a series of industry chain. Due to the terrain, climateand environment and a series of uncertain factors, there are many of uncertainty in the airinterface of the Base station system in access technology and implementation process. Soin the BTS (Base Transceiver Station) development process must invest a lot of resourceson the base station air interface RF specifications and conformance, reliability and stabilitytesting. The modern automated test systems with the high accuracy and efficiency becomea new emerging research projects in the wireless base station development.This paper implements a testing system which based on graphical programminglanguage LabVIEW, R&S (Rohde&Schwarz) FSQ spectrum analyzer and SMU signalgenerator. Force on the measured for TDD-LTE air interface RF performance and BTSconformance. The system utilizes the TCP/IP, GIPB computer communication technologyto automatic control the base stations and spectrum analyze, finished the RF performancetest items for BTS conformance and reliability side. And after the testing, the system savedthe test results through Access database LabSQL. Finally, through the measurement systemanalysis tool GRR (Gauge Repeatability and Reproducibility) to verification andevaluation the test systems. Finally did the analysis and future development for theresearch projects results.
