IOT Applications and Services Test
Analyse Assure AccelerateTM
IOT, Applications & Services Testing
• Interoperability testing (IOT): Network, cell, broadcast and radio channel configuration is
a delicate combination that varies from operator to operator
UE interoperability with different network conditions and configurations needs to be tested in the lab prior to deployment
• Applications and services testing: Test tools need to help identify issues with end-to-end
applications to help manufacturers and operators identify field issues in the lab prior to deployment
A wide variety of circuit and high-speed packet services (over an IP connection) need to be tested
Analyse Assure AccelerateTM
UE Performance Benchmarking
• Benchmarking UE functional performance: With UEs at various stages - from early
development to field trials and deployment, UE manufacturers need to test updated firmware and software of current models quickly
Network operators want to benchmark performance and functions of multiple UE models (and often multiple versions of each model) accurately and repeatably to help understand deployment issues
Regional and country-specific variations require a high degree of flexibility in the test system
