Job Responsibilities:- Performed handover tests, stationary DL/UL throughput test WCDMA/UMTS call test as well as mobility and cluster drive performed IRAT and reselection test, ensuring neighbour sites are up and identified by the cells.- Worked with a team of engineers doing extended feature testing include HSDPA.- Performed pre and post migration cluster drives.- Spatial diversity scheme to detect this weaker signal with good SNR.- Ran multiple tests simultaneously making sure tasks to be complete on time.Used MAPINFO tool to create drive routes around ATT cellular site for performing drive testing.Analyzed logs in TEMS discovery (Events-Layer 3 logs) for identifying issues in coverage area.- Spatial distribution of WCDMA signal around receiver shows that due to constructive interference there is enhancement in strength of weaker signal.- Analyze drive test data on TEMS, and TEMS Discovery for network analysis, site verification, problem identifications and solutions.- Understanding of Inter, Intra, and IRAT relations and concepts of handover.Performing CS call (MO & MT) and PS call (HSUPA & HSDPA) testing, throughput testing, signal verification, site verification.- Hands on experience with 2G/3G/4G Drive testing and its logs analysis and field issues solving.Analyzed (in 2G/3G/4G) interference, call drops, handover failures, Rx Quality, Rx level etc.
