  • Implement setups specifically for Massive MIMO (mMIMO) and Multi-User MIMO (Mu-MIMO) testing.
  
  
  
  


• 
  Test Specifications & Planning:
  
  
  • Develop detailed test specifications and cases for O-RU validation, covering scenarios including conformance, performance, interoperability, mMIMO, and Mu-MIMO testing.
  
  
  • Formulate robust test plans for both standalone and integrated E2E validations, with a focus on 5G E2E testing requirements.
  
  
  • Tailor test plans to meet customer-specific requirements, lab protocols, and industry standards.
  
  
  
  


• 
  Test Execution & Validation:
  
  
  • Execute test plans and perform conformance, performance, and interoperability testing for O-RU products using advanced RF test equipment and simulation tools.
  
  
  • Validate O-RU performance, mMIMO, and Mu-MIMO capabilities, and ensure adherence to industry standards.
  
  
  • Conduct 5G E2E testing, including the integration of multi-vendor RAN components and extensive interoperability testing.
  
  
  
  


• 
  Data Analysis & Test Reporting:
  
  
  • Analyze test results, capturing critical performance metrics and conducting root cause analysis for identified issues.
  
  
  • Generate detailed, structured test reports summarizing findings, key insights, and test methodologies.
  
  
  • Provide actionable feedback to support product enhancement and quality improvement efforts.
  
  
  
  


• 
  Documentation & Continuous Improvement:
  
  
  • Maintain thorough documentation of test procedures, configurations, and setups for reproducibility and audit purposes.
  
  
  • Contribute to continuous improvement initiatives by optimizing test methodologies, refining processes, and adopting new testing tools and techniques.
