Handling customer bug Fix and log analysis for the issue bugs and track them in defect tracking system.
Currently part Sequans SI where I was working on the L1 Features like (G-SYNC) attach performance, Cell re-selection reproducing the issue scenario against amarisoft .
Involved in debugging the issue on the particular feature raised in the live network and reproduce the issues on the local UE setup Calliope2 hardware) on the Calliope2 modem
Working against Amariaoft scripts,Dmtf Automation, CMW500 tools,
Working on the live network performance and attach issues, Cell re-selection based on multiple cases and scenarios
Working on the iperf Tput where CQI and MCS reported as per expected in the multiple modes like TM1, TM2, TM6.
Integrate the features on the DSP that compute CQI on the Calliope2 and try to reproduce the issue caused Tput degradation through automation script against Amarisoft and debug the root cause of the issue to check the proper mapping of CQI vs MCS
Worked on TMO data performance test to see the expected data rates were acahived through automation script and configure the fading effects against amarisoft on various bands that supported.
