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.

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

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.
