Realistic test conditions for module development
and integration

When developing wireless devices, it is essential to test
the communications interface under realistic network con­ditions. The R&S®CMW emulates the base station for all
technologies required to test these devices.

development to
production

The radio access network and the core network are imple­mented for each technology to be tested. The R&S®CMW
handles all protocol layers – from the physical layer to
the application itself. Signaling messages are dynami­cally created at runtime and are adapted to the DUT’s
requirements as needed.

Different applications place different demands on

testers. Development requires the simulation of
networks with standardized cellular and non-cellular
call processing sequences. Production requires short

test times and high precision.

All-in-one test platform for wireless devices

R&S®CMW platform – the perfect measurement
solution for IoT applications

The growing IoT markets need to test and analyze cellular
and non-cellular standards. The challenge is providing this
capability in a simple setup with only one connection.

The R&S®CMW platform offers a unique combination of
cellular and non-cellular network emulations. Users can
effectively implement a wide variety of measurement tasks
with a single investment in equipment, training and adap­tation costs.

The R&S®CMW can be used to test handover within a
technology or between technologies. Separate LTE and
WLAN signaling allows detailed analysis of LTE WLAN
traffic offload. A simple setup suffices for all phases – from
protocol development to functional testing.

The increasing number of standards in a mobile device can
be a cause of poor transmission quality. The R&S®CMW
can also solve this problem. The in-device coexistence test
analyzes mutual interference and desensitization between
the standards.

Powerful solutions for special production

testrequirements

Rohde & Schwarz is a global leader in optimizing
production processes for wireless devices. The T&M
expert offers cost-efficient solutions to meet user require­ments. Examples include different modes to reduce test
time, optimize processes (capacity utilization) and test
up to eight RF ports in parallel. These optimizations fulfill
the demand for high measurement accuracy and perfor­mance. The non-signaling mode (transmitter and receiver
mode) is primarily used in production environments.
Non-signaling mode is mainly for receiver and transmitter
tests, which are performed using the internal RF generator
and RF analyzer.

Audio testing and voice over LTE (VoLTE)
performance testing

The audio quality of VoLTE and legacy standards (GSM,
WCDMA, CDMA2000®) depends on several network and
DUT factors. Examples include radio conditions, packet
loss, packet delay, jitter and jitter distribution. Another
challenge is the fact that all current LTE network deploy­ments are optimized for data service, but not for voice.
Voice transmission has to be optimized afterwards.

Video testing

Video stability and performance are key performance in­dicators for E2E video streaming. They must be optimized
based on a variety of standards, including LTE (FDD/TDD),
WCDMA/HSPA, GSM/(E)GPRS and WLAN. Complex mea­surements are needed for services such as LTE Broadcast
(eMBMS), which requires optimized spectral efficiency at
the cell boundaries as well as low battery consumption.
These measurements can be performed easily and effi­ciently with the R&S®CMW.

User experience testing scenarios

The proliferation of wireless devices has led to enormous
growth in global IP traffic. At the same time, users are de­manding better audio quality, video streaming and data
transmission. Network operators, device manufacturers
and app developers need to ensure and optimize a certain
quality of experience (QoE) for the wide variety of services
based on these functions. A number of different parame­ters are used for optimization, such as the signaling traffic
per app (end-to-end traffic), the number of bytes (IP) con­sumed per app and the impact on the battery life.

User experience testing scenarios

Audio analyzer, e.g. ¸UPV

Video analyzer, e.g. ¸VTE

Data throughput testing

Depending on the IP data throughput (E2E performance),
additional IP analyses across different layers are possible.
These analyses reveal who generates how much and what
E2E traffic, and how the traffic can be optimized for the
various applications. The stability of the IP application can
also be tested with specific IP impairments. In parallel with
the E2E performance measurements, the R&S®CMW can
analyze the PHY and MAC layer throughput and measure
RF parameters such as EVM and UL power.

Application testing and typical use cases

Battery life and current drain measurements

Battery power consumption is gaining in importance as
a criterion in the analysis of chipsets, IoT modules and
mobile devices. With an increasing number of apps con­stantly running on smartphones, there is a risk that not
enough battery power is left for voice calls, hence the
implementation of creative features such as discontinu­ous reception (DRX), which is a power saving mode in
LTE intended to greatly improve battery life. However, the
application behavior needs to be tested and analyzed in a
controlled, emulated network environment.

Another possible test scenario is the correlation between
current drain and signaling or IP activities. Specific signal­ing trigger events as well as IP activity trigger events from
the R&S®CMW500 built-in IP analysis are displayed in a
current drain diagram.

Over‑the‑top (OTT) applications

OTT apps are active in the background and generate a pe­riodic RRC connection to the operator. This results in addi­tional signaling traffic, including data exchange. This traffic
interferes with other applications and significantly reduces
the battery life. The goal is to keep this type of signaling to
a minimum.

The following measurements can be performed with

theR&S®CMW and additional instruments:

❙ Veri cation of the audio quality with established

algorithms such as PESQ and POLQA under fading and
IP impairment conditions

❙ Video testing with all key performance indicators for

video quality, incl. SNR/SSIM/MOS values
❙ Testing of VoLTE calling parallel to data throughput
❙ IP data throughput and analysis testing, incl. OTT

The R&S®CMWrun sequencer software tool is an
all-encompassing automation tool for audio/video
performance and battery life testing. Any deviations from
the expected audio and video output can be automatically
and precisely detected. R&S®CMWcards, the graphical test
script definition tool, offers a wide range of test sequences
for 3GPP signaling, including failure scenarios.
