Responsibility:
• Executing the different WCDMA and LTE test cases
• Conducting KPI and sanity test suites for Qualcomm proprietary chipsets
• Functional feature verification of Qualcomm devices in WCDMA and LTE. Features
include basic MO/MT voice call, PS Call, SMS verification and soft handover
• Involved with in depth performance testing of 4G Cellular standard
• Testing various inter frequency handover scenarios between different bands namely,
IMT, PCS, Cellular, Band 8 and same as different bands in LTE
• Execution of Inter Radio Access Technology (IRAT) tests which involves successful
handover of a certain cellular standard to another cellular standard namely W to G and
L to W
• Testing in LTE covers scenarios such as Circuit Switch Fall Back (CSFB), carrier
aggregation (CA) , Handover and Throughput scenario in clean channel as well as
fading environment
