What is “Conformance Test”?
Determine to what extent a product implemented based on a particular
standard conforms to the individual requirements of the standard.
Conformance Test System
e.g. Agilent T4010S Test System
EUT - Equipment Under Test
e.g. LTE UE
Conformance Test

LTE Conformance and Regulatory Certification Introduction

Defining Conformance
Specific set of tests performed:
According to standards
By an approved test lab (could be manufacturer’s own)
On an approved test platform
Only devices that pass the tests can be released into the market
All other types of tests are called pre-conformance or D&V
Test Specs
(TS…..)
- A set of test cases
- Includes bands of operation
- Constantly evolves, over
‘releases’
Test Platform
(TP…..)
- Approved test systems/tools
/instruments
- RF, PCT or RRM
- Must keep pace with standards
- Covers 80-90% of TS to be
approved
Validation
- Done by test lab to approve
test case implementation and
test platform

GCF Organization
• GCF (Global Certification Forum) Certification is defined and
maintained by GCF members collectively.
• The Conformance and Interoperability Group (CAG) identifies the
Certification Criteria (CC) through laboratory testing.

PTCRB Organization
• PTCRB (PCS Type Certification Review Board) framework for GSM,
UMTS and LTE UE certification services for North American operators.
• The PVG (PTCRB Validation Group) is a group of test laboratory
organizations working in the field of PTCRB associated technologies.
PVG works on open PTCRB RfTs (Request for Testing) and the validation
of Test Platforms and Test Cases for the relevant PTCRB operating
frequencies.

Want to test more – Operator Acceptance Testing
Operators are performing more rigorous conformance and
acceptance testing of devices before marketing them to
customers. The goal is to ensure devices promoted for their
network will meet customer expectations.
T4010S LTE RF test system covers the following test plans:
• AT&T 10776 RF and RRM test cases Verizon RF
Supplementary Test Cases
• Verizon RF Supplementary Test Cases
• Sprint RF Supplementary Test Cases
• TELEC LTE RF Test Cases
• T-Mobile RF Supplementary Test Cases

AT&T -Search real sensitivity of each component carrier
• UEs with better sensitivity performance will
increase the effective LTE-A coverage
• Sensitivity is verified at several frequencies,
bandwidths and modulation schemes
• Performance grade for easier
benchmarking
Ensure best performance at the edge
