Worked on 2 projects in Millimeter wave (60GHz) TestingProject 1:FB Terragraph - SI Performance/Throughput Analysis of 60GHz RF modules : MCS RVA curve plots for both Diversity and Massive Antenna Testbeds. Break point calculations- SNR Degradation Calculations - TPUT/PER Analysis for both TCP and UDP Traffic.Longevity Tests on both Massive and Diversity TestbedsOven tests for Temperature gradient Testing to verify the RF compatibility for both higher and extremely Lower temperatures.Worked on a couple of Customer Issues including SIKLUs SNR Degradation issue, Cambium Asserts, 1dB degradation on the RVA tests etc.Project 2: SIE (Sony Gaming Project)Latency Metrics for 60GHz Gaming device- AP/STA latency Metrics , Interframe/Chunk and Packet Latency measurementsWorked on Power Metrics measurements using both QEPM and Kratos Utralite and Kratos Next gen.Reported More than 50 JIRAs across different issues faced in the gaming project related to Latency metrics/SNR/PER/TPUT etc.Handled and successfully delivered one complete customer release.Worked on Raw Python Automation for handling the test scenarios.Other areas explored : Started working on Machine Learning introduction topics and worked on sample datasets for Linear/Exponential/Decision Trees/Random Forest based models.(Currently in progress).Tools/Testbeds worked: QEPM- Power Measurement Tool, Kratos NextGen for Power Measurements - Shallow/Deep/Idle Assoc/Unassoc states , Si-Web (GUI based Automation), Raw Python , Oven based Temperature Testing for 60G-WiGiG RF’s, MATLAB for TPUT/SNR/CTS related informations.Android based STA bring up - Android-U/T, Android Testing, RVR-Traffic Emulator(Burst UDP traffic)Built 60G-WiGiG setups for Line of Sight/Non-Line of Sight/Power, RVA tests- Massive/Diversity RF based deployments.
