Accelerate Device Excellence: In The Lab

Accelerate Device Excellence: In The Lab

This white paper focuses on a more effective, end-to-end test methodology for mobile device lab test teams. This methodology is based on these principles:

  • Track device performance in real-world environments
  • Closely scrutinize device-network interaction
  • Adopt an end-to-end approach in evaluating device performance
  • Use test methodologies designed for complex devices.

The enablers of this methodology are:

  • Field-to-Lab (FTL)
  • FTL with Dynamic Reciprocal Path Loss
  • Over-the-Air with Field Playback

This white paper describes these solutions, and uses case studies with quantitative results to demonstrate their operation and benefits.

Accelerate Device Excellence: In The Field

Accelerate Device Excellence: In The Field

This white paper focuses on a more effective, end-to-end test methodology for mobile device field test teams. This methodology is based on these principles:

  • Track device performance close to what the end-user will experience
  • Closely scrutinize device-network interaction
  • Adopt an end-to-end approach while understanding device performance
  • Harmonize field and lab testing
  • Use an effective test methodology that makes sense in the context of complex devices.

The enablers of this methodology are:

  • Device Automation & Control
  • Diagnostics & Analytics

This white paper describes the solution, and uses a case study with
quantitative results to demonstrate its operation and benefits.

Ignore Device-Network Interaction and Risk your Customers!

Ever increasing network and device complexity has increased the impact of device-network interaction on the subscriber’s experience. Unfortunately, testing has not yet caught up and instead remains focused on device- specific or network-specific KPIs. Operators, infrastructure and device vendors may all profit from a new focus on device-network interaction and could realize immediate benefits in reducing time to identify root causes of poor performance.

Testing True Mobile Device Performance with Advanced Over-the-Air Testing

The white paper explores a new MIMO/SISO Over-the-Air testing methodology that combines the use of channel emulators that use propagation models to recreate the dynamic over-the-air conditions typical in mobile wireless conditions with a mobile isotropic chamber, an environment for testing electromagnetic compatibility, that provides the most balanced and cost-effective approach to achieving repeatability while producing realistic performance results.
