Application Card | Version 01.00

Ever wondered how you can test your C-IoT device for

❙ Application testing use cases

❙ Protocol signaling use cases

❙ Reproducing eld issues

or a combination of all this in a cost efficient way?

R&S®CMWcards

for C-IoT

Rohde & Schwarz offers a variety of products to fit your

testing needs. Here, we present our solution for testing

the above-mentioned use cases.

In C-IoT, the dominant technologies are LTE Cat 1, eMTC

and NB-IoT. All these technologies aim to reduce the com-

plexity on the device side, to reduce the cost and to in-

crease the coverage to reach often hard-to-reach regions.

Since these technologies reduce the cost to manufacture

the device, the natural question is how to also drastically

reduce the cost to test the functionality of these devices.

Rohde & Schwarz offers a cost-effective variant of hard-

ware and software products that take this into account

and also promise exceptional quality.

Hardware platform

Rohde & Schwarz offers the R&S®CMW500 radio com-

munication tester and the R&S®CMW290 functional radio

communication tester to meet different testing needs.

The R&S®CMW500 radio communication tester is an all-in-

one test platform that can be highly customized and that

caters to several use cases, including those mentioned

above. This is not cost-effective from a hardware perspec-

tive, but it would be the right investment choice if the goal

is to scale the product configuration in the future.

The R&S®CMW290 functional radio communication tes-

ter is a compact version of the R&S®CMW500. It has a

reduced feature set, which lowers the hardware cost and

makes it ideal for C-IoT/M2M customers since it provides

the needed functionality for C-IoT testing use case.

R&S®CMWcards

Play while you work

R&S®CMWcards is a software application based on a card

game that can be used to create test scripts for C-IoT.

Cells are created by simply placing cards next to each oth-

er, and each cell can be parameterized in a graphical way.

R&S®CMWcards helps the user by indicating the possible

errors that could have crept in while parameterizing the

cells, keeping the test script consistent and error free.

The R&S®CMWcards application is available on both the

R&S®CMW500 and R&S®CMW290 testing platforms. The

same application installs on a laptop and can be used to

create test scripts locally on the laptop. The created scripts

run on the R&S®CMW platform remotely.

Cellular internet of things (C-IoT) protocol and

application testing with R&S®CMWcards

Objective

❙ Create functional protocol and application test cases as

well as regression campaigns for cellular C-IoT devices

that support LTE Cat 1, Cat M1 (eMTC), Cat NB1 (NB-IoT)

and Cat NB2

❙ Verify that the device can correctly perform network

attach, establish a data connection (SMS, IP and non-IP

data) and perform mobility procedures

❙ Investigate devices’ interoperability capabilities for

different C-IoT deployment modes, especially for NB-IoT

standalone, in-band and guard band mode.

❙ Create typical negative testing failure scenarios that are

hard to reproduce in real-world networks, e.g. attach

reject, mobility failures, repeated rejections of the device

under test

❙ Rel-14 NB-IoT LBS location verication using NPRS

(OTDOA)

Testing scope

❙ Network simulation of LTE cells as well as 3GPP Rel-13

eMTC and NB-IoT enhancements

❙ Support of UE categories Cat 1, Cat M1, Cat NB1 and

Cat NB2

❙ eMTC, NB-IoT CE mode A and B (coverage

enhancement)

❙ Flexible configuration of NB-IoT deployment modes

(standalone, in-band and guard band)

❙ Crucial timer settings (e.g. T3412 or T3324) for sleep

modes such as discontinuous reception (eDRX) and

power saving mode (PSM)

❙ Cell selection and reselection scenarios

❙ Definition of reject causes for network reject scenarios

(EMM attach reject) or mobility failures

❙ Test positioning for C-IoT devices

❙ Data end-to-end tests for IP and non-IP applications as

well as SMS

❙ Maximum IP throughput tests

Licensing

Uncomplicated and fair

R&S®CMWcards application can be unlocked on any

platform (laptop, R&S®CMW500, R&S®CMW290) with

the R&S®CMW-KT044 license. This one license covers all

C-IoT technologies and releases, with the latest protocol,

usability and GUI features. To execute the tests on the

R&S®CMW500, an R&S®CMWcards framework license is

needed to unleash the full potential of the hardware and

software of the R&S®CMW500 to simulate all C-IoT tech-

nologies. The framework license is R&S®CMW-KP030.

A similar license is needed for test execution on the

R&S®CMW290, except that it has an even lower price. The

framework license is R&S®CMW-KP020.
