Current UE Test Challenges



RF Conformance:

• Availability of validated, GCF-approved tests for UE conformance testing and certification

• Confidence in meeting the requirements of the specifications: test tolerances, test procedures and measurement uncertainty

• Confidence in obtaining accurate and repeatable results - rigorous calibration procedures needed

• With multiple UE models and versions coming to market, high test throughput is required

• Ability to test UEs that operate in different regions (operating bands)



RF Performance:

• With UEs in multiple stages of development and deployment: platform development, product realisation R&D and design verification IOT and field trials

focused testing is needed in specific areas, e.g. receiver performance with transmission impairments handovers RF and baseband testing Radio Resource Management layer testing


Spirent’s Conformance Solutions


Spirent’s RF Conformance Solution

• U-ATS – a scalable conformance test solution that runs independently-validated, GCF-approved RF conformance test cases from 3GPP TS 34.121 Sections 5-8

• Accurate and repeatable testing assured by calibration that is rigorous and frequency-specific, yet time-efficient

• High level of automation, including support for UE and environmental control, and remote operation capability to maximise test throughput


Spirent’s RF Conformance Solution

• Single turnkey system covers RF parametric and Radio Resource Management (RRM) conformance testing

IOT Applications and Services Test


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


• A real-time “active” state machine with response times representative of real networks

• Emulation of virtually any multi-cell deployment scenario (up to 6 cells, 3 nodeBs and 2 RNCs)

Spirent Solution - AirAccess WCDMA

AirAccess WCDMA is fully-configurable, multi-cell “network in a box” that provides:

• Quick and easy setup without the need for scripts or programming

• Emulates circuit and high-speed packet services, including QoS testing
