What is “Conformance Test”?
4
Determine to what extent a product implemented based on a particular
standard conforms to the individual requirements of the standard.

Defining Conformance
5
Specific set of tests performed:
• According to standards, i.e. Test Specifications
• By an accredited test lab (could be lab owned by manufacturer)
• On a ‘recognized’ test platform
Test Specs
- A set of test cases
- Includes bands of operation
- Constantly evolves, over
‘releases’
Test Platform
Validation
- Approved test systems/tools
/instruments
- RF, Protocol or RRM
- Must keep pace with standards
- Proof validation for a certain
percentage (e.g. 80%) to be approved
Lab
Accreditation

requirements defined by a 3rd
party, e.g. ISO 17025.
- Must use validated TPs.

Preparation process for UE Certification
10
Each certification body selects a group of test cases and
defines their priority based on operators’ plans
Test system vendors develop the test cases required
on their test platforms
Each test system vendor selects an accredited lab to
validate their test cases using reference UEs
The lab submits a validation report to the specific
certification body for approval, enabling the test system
and the test cases for certification
Certification bodies do not adopt
the entire 3GPP test specs

Operator Acceptance Testing
18
The dramatic growth of ‘smart devices’ has increased the need of
further requirements on mobile devices before they are launched
on the network.
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.

Acceptance Tests
19
Designed around specific characteristics and conditions of the wireless network to
cover a multitude of scenarios that stress both network and UEs.
Details of an operator’s acceptance tests are usually confidential and differ in
specifications tested, measurement limits and implementation.
Operator’s technical requirements usually are:
• Regulatory: RF/EMC/Safety tests according to country standards
• Conformance: Tests against specific standards RF/protocol/SIM
• Interoperability: Tests compatibility between devices and devices to network.
• Functional Tests: Verification of functionalities and features.
• User Experience: Quality tests according to users expectations.
• Reliability: Endurance, extreme tests considering usage and different climatic
conditions.

Represent additional test requirements besides the inclusion of both
Frequency Division (FDD) and Time Division Duplex (TDD) modes.

The use of multiple subcarriers and the amount of BWs defined
dramatically increases the number of combinations under test.

Challenges of LTE UE Testing (& III)
23
Fading & AWGN simulators are required
Fading simulators and AWGN generators are
required tools for testing robustness due to
multipath reception and noise interference
effects.
Inter-RAT requirements
Testing LTE UEs require exercising other
radio access technologies (RAT) supported,
as well as new inter-RAT tests required by
the addition of LTE.
Testing time
The number of permutations that could be
tested is enormous and therefore the testing
time required to execute them.

Need for Design Verification tests
29
We are
developing an
LTE device.
Any bugs on it
will cost us
millions!
We need to verify
that everything is
working before
producing, both for
present and future
requirements
Current test specs
only covers a subset
of all possible
parameter
combinations…
standard test are not
enough!
We will need to develop our
own tests… that’s going to
require dedicated
development teams… and
we still will require to verify
compliance to conformance
specifications to certify the
solution…

• DV tests address these needs by
providing:
• User-defined and customized
tests.
• Deeper parameterization than
conformance.
• More restricted pass/fail
criteria.
• Traceability with conformance
test cases (pre-conformance).

requirement under these conditions
will decrease the effective
