Key Responsibilities:
Going through 3GPP standards, architectural and design documents to come up with thorough and in-depth test plans for testing LTE eNodeB functionalities.
Creating test scripts using available test tools. This will involve getting familiarized with the test tools and figuring out innovative ways of re-creating practically possible scenarios
Executing test cases and validating the test status based on the expectations for the test case.
Using the test expertise and identifying overall improvements and enhancements which are possible on the system
Debugging field data and identifying potential problems and re-creating the same in the lab
Job Requirements
Ability to build test setups as per the requirements of the test case
Ability to fully understand system logs, test tool logs and use this understanding for debugging issues and identifying accurate root causes for the problems seen on the system under test or in the network
In-depth knowledge of LTE Access domain
Thorough understanding of 3GPP specs covering PHY, MAC, PDCP, RLC, RRC, S1AP and X2AP protocols
Hands on work experience of testing LTE eNodeBs
Hands on experience in using test tools including but not limited to
UE simulators like Aeroflex TM500 and IxLoad Wireless.
UE debuggers like QXDM, XCAL and TEMS
Channel Emulators
Application traffic generators like iPerf, IxLoad etc
Knowledge of message flows and parameters used in the messages for LTE procedures
Understanding of LTE Release 10 and Release 11 features
Familiarity with LTE SON functionalities is desirable
Familiarity with application layer optimizations; TCP traffic optimization, Video traffic optimization etc.
Familiarity with scripting languages like Python and Tcl
5-12 years of relevant experience in the wireless telecommunications industry
Bachelor/ Master’s degree in computer science, electrical engineering is required. MBA is a plus
