Successful deployment of LTE technology is a massive, complex
undertaking. By applying unique experience gained through deep
involvement in mobile device performance testing, Spirent solutions
help to prevent bottlenecks and costly resource drains in early LTE
device deployments.
When a mobile device causes issues, operators are held
responsible; subscribers neither know nor care that the device
may be the cause. Operators can lose subscriber revenue while
absorbing increased operating and support costs. Leading operators
in the forefront of early LTE deployments recognize these risks and
are putting in place comprehensive device acceptance test plans to
help mitigate them.
Spirent’s unique LTE device test solutions address RF, Data, Mobility
(Inter-RAT), Location-Based Services (LBS) and Simultaneous
Voice and LTE (SVLTE) performance. A collaboration with leading
test vendor AT4 wireless enables Spirent to also offer complete
RF, Protocol and Radio Resource Management (RRM) Conformance
testing to industry standards.
LTE Performance and Conformance solutions make use of the same
key test platform components. Spirent’s LTE solutions are scalable,
making it easy to buy only what is needed to meet existing testing
needs, then add capability as those needs evolve. This flexibility,
coupled with the ability to cost-effectively upgrade existing Spirent
CDMA or GSM/UMTS tests systems to add LTE capability, ensures
that your investment in Spirent solutions continues to pay back
throughout the product lifecycle.
Due to the complexities inherent in LTE, device performance is now
a more important component of a successful deployment than
ever. Only Spirent has the industry-leading breadth and depth
of experience in device performance testing to help ensure your
success.

CONFORMANCE TESTING AND PERFORMANCE
EVALUATION ON A SINGLE PLATFORM
The breadth of Spirent’s LTE test coverage means that you
can start with the testing you need right now, confident in a
straightforward path to meet your future testing needs. Whether
the starting point is CDMA/EV-DO or GSM/UMTS testing, or a
dedicated entry-level LTE station, Spirent offers upgrade paths
that match solution capabilities to your testing requirements.
With the 8100 system, your test capabilities evolve according to
your planned testing schedule.
Performance issues can affect subscriber acceptance and can
impact subscriber support costs. Spirent’s LTE performance
test solutions quantify device performance in the most critical
areas. Beyond testing for conformance to industry specifications,
the 8100 is indispensible in comparing device performance,
gathering data for operational and support cost projections,
or just for identifying issues that are not caught by basic
conformance testing.
A single set of hardware does more than help get your device
ready for operator acceptance testing. Thanks to Spirent’s
cooperation with AT4 wireless, the same platform used for
performance testing can be re-used for pre-conformance
testing or validated industry-standard LTE conformance
testing.

EXTREMELY FLEXIBLE EVOLUTION PATHS
Spirent systems are designed to help you extract the most value
from your investment. If you’re implementing a brand new testing
station, you can start with a basic small-footprint bench-top
conformance/performance testing system and add capabilities
as you require them. An extremely rich set of options ensures
that you can upgrade performance test cases (from Spirent) or
conformance cases (from Spirent and AT4 wireless) so that your
capabilities match your testing schedule.
Owners of existing Spirent systems (for either GSM/UMTS
or CDMA/EV-DO testing) have straightforward paths to LTE
performance testing. By designing LTE solutions to re-use as much
Spirent equipment as possible, owners of existing ULTS or C2K-
ATS systems, for example, are one painless upgrade away from
the world’s most advanced LTE testing.
HIGHLY CONFIGURABLE, CONTROLLABLE REAL WORLD
TEST CONDITIONS
Spirent solutions make use of a fully-configurable, controllable
environment including sophisticated Evolved Packet Core (EPC)
emulation. Spirent’s award-winning eAirAccess network emulator
is the most powerful and complete network emulation available
for cellular device testing, including LTE and eHRPD. The resulting
emulated multi-mode network is the heart of the industry’s
most complete platform for mobility testing, including Inter-RAT
handovers and much more. The system is capable of emulating
two carriers per RAN technology (CDMA, UMTS, LTE), up to 6
carriers and 13 cells/sectors.
An integrated industry-standard SR5500 Wireless Channel
Emulator adds fading and interference for real-world performance
analysis of MIMO implementations, a key factor in LTE success.
No Hidden Surprises
Spirent test solutions show you what’s
beneath the tip of the iceberg, so you
can isolate and correct issues before
deployment.

LTE TEST THEMES
Spirent LTE device testing solutions include performance
testing, parametric testing and testing conformance to industry
standards. In order to offer solutions based on expertise in
key areas, some testing themes were developed through a
partnership between Spirent and AT4 wireless. LTE test themes
addressed by Spirent systems include:

LTE Data Retry – Spirent pioneered Data Retry testing several
years ago, helping operators avoid network breakdowns
and device manufacturers to avoid taking public blame for
outages. How does a mobile device behave when it is denied
service due to a failed service, gateway denial or unavailable
network resource? Spirent’s LTE Data Retry testing finds out
before your customers find out for you.

LTE Data Throughput – A data-centric service such as LTE
requires detailed performance testing using various transport
mechanisms, RF scenarios and data client setups. Industry
leaders have publicly praised Spirent’s expertise in the
fine points of wireless data performance testing. Today this
knowledge base is the driving force behind automated data
testing on the 8100 system.

LTE Inter-RAT – Inter-Radio Access Technology testing is a
critical component of LTE testing. For example, when LTE is
overlaid with CDMA services (including eHRPD functionality)
the mobile must be tested to ensure proper handover
operation. LTE launches have already pointed out the
importance of careful mobility testing of devices.

LTE Location-Based Services (LBS) – The last few years have
proven that location-based applications are among the most
popular used by wireless subscribers. There’s no question
that they will continue to be important as LTE evolves. Of
course, there are new complexities involved. For example,
some LTE deployment bands are harmonically related to GPS
signals and must be tested for interference. For another,
satellite navigation is beginning to mean more than just
A-GPS: some implementations will rely on GLONASS satellites
while other deployments (e.g. Galileo) are just around the
corner. Spirent’s undisputed leadership in Sat-Nav and LBS
testing goes a long way toward ensuring the success of these
vital services.

LTE RF Performance – wireless RF performance testing is
one of the areas in which Spirent has consistently proven
technical and market leadership. The extension of this
leadership into the LTE arena is evident in the RF performance
test cases provided for 8100 system testing.

LTE RRM Performance – Radio Resource Management is a
critical system-level factor in ensuring high-quality, cost-
effective LTE service delivery. While RRM conformance testing
ensures that a device meets minimum RRM standards,
network operators and device manufacturers want to know
more. Spirent’s 8100 system delivers that information in an
accurate, automated solution.

LTE SVLTE – When LTE is an overlay to a CDMA/EV-DO
network, the current de facto standard for voice delivery is
Simultaneous Voice Over LTE (SVLTE). In this arrangement,
voice service is deployed as a 1x service running in parallel
with LTE data services. This means protecting against
potential unwanted interference between the two services and
testing all relevant combinations with the automated Spirent
system.

LTE RF Parametric – Most of the component elements of
the 8100 system can also be run as stand-alone bench-top
instruments for debugging or detailed analysis, and the
E2010S network emulator is no exception. In fact, the E2010S
has dual use cases as a stand-alone instrument: when loaded
with eAirAccess network software, the E2010S is the heart of
a completely integrated multi-RAT emulated network. When
loaded with AT4 wireless’ S3110B application, the E2010S
becomes a powerful touch-screen-controlled TX/RX parametric
tester offering multiple parameter views on a single screen.

LTE RF Conformance – Spirent offers a comprehensive set of
RF FDD conformance test cases developed by LTE partner AT4
wireless

LTE Protocol – Spirent’s 8100 system runs a comprehensive
set of test cases called out in the 3GPP’s 36.523-1 test
specification.

LTE Radio Resource Management (RRM) Conformance –
Spirent offers repeatable, accurate testing according to the
3GPP’s 36.521-3 test specification.

DATA-SPECIFIC TESTING FOR A DATA-CENTRIC WORLD
Quantifying LTE data rates on live networks can be challenging,
given the highly-variable nature of real-world RF environments.
Insufficient device testing in this area leads to increased support
costs, increased operational costs, and lost revenues due to
unhappy subscribers. Spirent solutions provide fully-controllable
environments and automated testing to ensure success for both
operators and mobile device manufacturers.
Thanks to Spirent’s legacy as the world’s leading provider of
channel emulators, Spirent test systems include realistic RF
channels for testing. It’s not enough to know about data rates
on a “clean path” lab setup. It’s not even enough to know what
happens with a small number of limited test scenarios. Spirent
data testing gives you the flexibility to customize completely
realistic and controllable network and RF environments for your
testing.
ADDRESSES CRITICAL LTE RF DEPLOYMENT
CHALLENGES
Realistic testing goes well beyond basic conformance
requirements. Every LTE deployment faces a specific set of
regional issues and spectrum usage issues. Released devices
must not interfere with, nor be adversely impacted by, pre-
existing signals.
For example, upcoming North American rollouts will be deployed
in the 700 MHz band, where they need to be a good neighbor to
signals such as:

Digital TV

Public safety bands
As another example, in a US 700 MHz spectrum block, the
second harmonic sits squarely in the middle of the GPS L1
channel.
Interfering with any of these services risks the imposition of
significant liabilities. In the same vein, an operator needs to
know that the presence of these signals won’t affect the ability to
deliver quality service at a reasonable cost.
Today’s wireless subscriber is more sophisticated then ever, and
the media focuses an increasing amount of attention on wireless
service and device quality. As subscribers become more and
more knowledgeable in comparing cellular offerings, operators
need to ensure that they can deliver fast connection and set-up
times without initiating unnecessary roaming charges. Testing
with Spirent is the industry’s most reliable way to make sure your
deployment will be what you need it to be.
