Project 1: LTE IOT and Field Test Back Office log Analysis.

Locations: Bangalore (India), Dallas (USA) & Santa Clara (USA)

Client: Intel Mobile Communication

 

Job Profile:

Responsibilities include debugging of failures seen in IOT and Field Test of the LTE UE Stack. Failures need to be root-caused to the right sub-component. Responsibility includes interacting with development and test teams to ensure critical blocking bugs are resolved avoiding delay in issues resolution by routing to proper sub-components of UE.

 

Key Contributions:

 

·               System level analysis of Field test logs and identifying issues.

·               Raising new CR and routing the issue to proper UE subcomponent to help developer and minimizing their load.

·               Throughput testing carried out for static and mobility test cases, which include file transfer (Upload/Download) using Total Commander or Filezilla.

·               Providing AT command sequence document to testers to ease test case execution.

·               Contributed to analyzing data stalls seen in field test and IOT environment.

·               Analysis of issues related to low data throughput.

·               Analysing field testing logs captured in different locations and providing support in case of any issues.

Project 2: LTE Pre-IOT Test Case Development and Debugging

Location: Bangalore, India

Client: Intel Mobile Communication

 

Job Profile:

Responsibility includes design of scenarios that would simulate failure of LTE UE stack in IOT and Field-testing and could be automated using TTCN-3. The testing was done during conformance testing thereby reducing the failures seen at IOT and Field Test levels. Scenarios included testing of inter-operability robustness between layers of LTE UE Protocol Stack, IRAT scenarios, collision, error and boundary conditions. Scenarios were also designed keeping in the mind the real-time usage by data users and failures occurring during it.

 

Key Contributions:

·               Contributed for identification of scenarios for Phase-1 & Phase-2 of project.

·               Preparation of design documents for various scenarios in accordance with LTE 3GPP standard.’

·               Reviewed test cases and provided additions/changes. Presented various test cases/scenarios to the business teams for approval
