• Assisted GPS (A-GPS) is currently the most popular highaccuracy technology choice
• A mobile’s A-GPS performance is an important part of any
overall location determination accuracy assessment
• Overall location determination accuracy is commonly
qualified by carrying out large, costly field trial campaigns

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

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
