Dear readers, dear participants of the 2017th M2M
Summit, For one day, the experts from academia, indus-
try and politics are settle together to discuss the latest
trends in M2M and IoT connectivity. This time we meet
in the LANXESS arena in Cologne at our joint event with
the StartupCon. For us, the M2M Alliance as the co-orga-
nizer of the show, there is good reason for a joint event. In
the first place there will be more than 5.000 visitors from
a wide range of industries. Furthermore, we introduce
parallel conference tracks to show all the variety of M2M
technology.
What happened since last years’ M2M Summit? Numerous
projects in industry and academia have been completed,
showing the full potentials of M2M connectivity. LPWA
technology, called the new dimension of IoT, is in the
main focus. Everyone is talking about those wireless pro-
tocols, boosting the number of connected devices towards
the magic number of 50 billion. Which of the numerous
standards is the right one for your next M2M/IoT project?
A dedicated roadmap for the future is still missing. I am
sure the experts on stage are happy to guide you through
the jungle. Enjoy more than thirty talks about our core
topics M2M Connectivity, Smart Factory, Standardization,
Data Security, Big Data and Connected Living.
Learn how the rise of the machines will affect your life
today and in the future!
That is our headline for this year. To be honest, a block-
buster movie with an Austrian actor was also on my mind
at first. But we are not here to draw a gloomy future with
robots threaten our lives. The promise is that the tech-
nology will benefit us all. Higher productivity in industry
makes lot size one has become the norm. Our modern
logistics as a complex and fragile system are based on
millions of connected devices. Looking at the mass market
of smart home appliances, one could hardly imagine a
world without our voice service friend from the black tube,
shipped in less than a day, of course. And only if you have
one dot in each room you might name your home a smart
home.
What is the right amount of connectivity we need in our
modern life? For me, every new technology, product or
service which saves time during the day is a good one.
Here is my favorite, I hardly can wait for real autonomous
driving. Think about the total amount of time and its value
we will save in a world of interconnected devices.
And what to do with the extra time? I suggest we let the
machines do the extra job and spend more time with our
families, the most powerful (private) network in the world.
And of course, take some of your time to visit a high class
conference, to meet colleagues and to absorb all the
latest trends in our M2M/IoT domain.
A warm welcome to the 11th M2M Summit. Enjoy the
show and dive into the fascinating world of connectivity.
In the name of all M2M Alliance board members I wish
you fruitful discussions, all the best and a nice stay in the
beautiful city of Cologne.
Sincerely yours

4 M2M ALLIANCE ENABLING DIGITAL TRANSFORMATION
The digital transformation is profoundly changing our bu-
sinesses and our economy. The lines between what used
to be clearly separated sectors are disappearing and new
value chains emerging. Digitisation is giving rise to new
business models that nobody could have thought of only
a few years ago. In Germany, we have coined the expressi-
on “Industrie 4.0” to describe this process – and to illustra-
te the fact that this development amounts to no less than
a fourth industrial revolution.
Within Industrie 4.0, M2M solutions play a very important
role. With ever greater numbers of machines and devices
communicating with one another autonomously, there
are ever greater amounts of data. This data can be used to
underpin new business models and to develop bespoke
customer solutions. M2M solutions can also help improve
manufacturing processes as real time data gives compa-
nies greater flexibility than ever when it comes to respon-
ding to change quickly.
For our country to be able to harness the full potential
promised by the digital transformation, we need to create
the best possible framework for this. How can we establish
uniform standards? How can we guarantee high levels of
data security? And how can we take the public on board?
These are only some of the questions that need answe-
ring.
We are in the fortunate position to have the M2M Summit,
a well-established industry event that provides us with a
platform for discussing these questions The M2M Summit
brings together experts and users from many different
countries. This is exactly what we need in order to be able
to press ahead with the digital transformation. It is for the
same reason that I gladly accepted the invitation to serve
as patron of this event.
I was pleased to see that the M2M Summit is taking place
in conjunction with this year’s StartupCon in Cologne. I
am convinced that dialogue between well-established
companies and start-ups is essential when it comes to
forging our digital future.
We also need to cooperate across borders. Geographical
distances and borders will increasingly lose importance
in an interconnected world. For this reason, it is good that
the M2M Summit also fosters international dialogue.
May all of the participants of the 11th M2M Summit 2017
find this event productive and informative, and may your
work be successful.

»MAX – the industry’s first
predictive maintenance
solution for elevators.«

AT FIRST GLANCE, IT SEEMS SENSIBLE.
WHY WASTE YOUR EFFORTS TRYING TO ALTER
SOMETHING THAT ALREADY DOES THE JOB?
However, in a world of fast-paced technical innovation,
old adages like this have no place. For anyone looking to
deliver maximum customer value and be at the forefront
of their field, complacency encouraged by an »if it isn’t
broken, don’t fix it« attitude will leave them behind.
Tech leader Microsoft is a great example of this. The com-
pany has consistently looked to improve on products that
customers were otherwise happy with. The Windows XP
operating system was hailed as one of the most robust
and effective since the launch of personal computers;
but Microsoft continued to build new systems that could
integrate more effectively with modern technologies. As
good as it was, Windows XP would not have sat as well
with modern tablets and laptops. It wasn’t broken, but
Microsoft still sought to build on it, to ensure their offering
provided as much value to their customers as possible.
At thyssenkrupp Elevator, we’ve ingrained this attitude
towards innovation into our business, working on the basis
of »it isn’t broken, but how can we be better prepared to
fix it?« In 2015, we teamed up with Microsoft to improve
elevators that are, for all intents and purposes, functioning
at the status quo. Together, we developed MAX – the in-
dustry’s first predictive maintenance solution for elevators.
With MAX, we go beyond simple remote monitoring and
into the realm of predictive and pre-emptive maintenan-
ce, allowing us to forecast when an elevator component
will need repairing, based on real-time data collection.
For our customers, this fixing of what isn’t broken will
mean a reduction of downtime – less waiting around in
the lobby due to an out-or-service elevator, fewer inci-
dents of having to take the stairs due to unscheduled
maintenance visits, and better planning when a visit is
needed. For our technicians, the relationship with their
customer moves from being a reactive one to a proactive,
more positive one. The data collected through the over
110,000 elevators connected with MAX has also given
us what is the industry’s first and largest data-based
knowledge pool on elevators, and with M2M learning,
MAX’s capabilities will just keep on improving.
SO WHY DID WE DO THIS?
Because whilst previous approaches got the job done, we
knew that elevator service could be done much better.
The pursuit of improved customer satisfaction, and inno-
vation to meet that goal, requires us to look at the status
quo and see how we can elevate it. As of October 2017,
we have connected over 100,000 units globally, compri-
sing 10% of our global maintenance portfolio. In parallel,
we are also working on offering MAX for escalators and
third-party elevators as well, ensuring our customers can
benefit from maximum uptime regardless of whether they
use a thyssenkrupp elevator or not.
And we continue to up the ante –steadily incorporating
the use of Microsoft’s HoloLens in our field operations to
allow our technicians to work hands-free while on the job,
and teaming up with logistics automation company Tele-
Retail to test delivery robots for elevator maintenance.
In a world as fast-paced and demanding as ours, it’s not
enough to settle for being reactive. Always looking for
ways to improve and bring value to our customers in
everything we do – that’s our approach to make sure
that long before it’s broken, we’re fixing it.
ANDREAS SCHIERENBECK
CEO THYSSENKRUPP ELEVATOR
THERE’S A COMMON ENGLISH PROVERB THAT GOES: »IF IT ISN’T BROKEN, DON’T FIX IT«. IT MEANS TO
AVOID SPENDING TIME AND EFFORT ATTEMPTING TO CORRECT, FIX, OR IMPROVE THAT WHICH IS ALREADY
GOOD OR OPERATING AT THE STATUS QUO. THERE’S A HIDDEN LAYER TO THE PHRASE, IMPLYING THAT
ATTEMPTING CHANGE CAN OFTEN BE RISKY AND MIGHT EVEN BACKFIRE.
IF IT ISN’T BROKEN
… FIX IT.

M2M AND IOT ARE NOT ONLY CHANGING THE ICT
INDUSTRY, BUT ARE ALSO ENABLING NEW BUSI-
NESS MODELS IN ALMOST ALL SECTORS OF THE
ECONOMY. THE M2M ALLIANCE PROVIDES COM-
PANIES AND STARTUPS A PLATFORM TO SUPPORT
INNOVATIVE M2M SOLUTIONS.
M2M technology and the Internet of Things are important
business fields for both start-ups and corporate compa-
nies. The M2M Summit, Europe‘s largest M2M Conference
and Exhibition with Academic Day takes place on 11 Oc-
tober 2017 in the LANXESS Arena in Cologne. On 80,000
square meters visitors will get an overview of the latest
M2M and IoT developments. A topic on the M2M Summit
will also be the new LPWA technology.
Joachim Dressler, M2M Alliance Board Member Finance
and VP EMEA/LATAM Sales at Sierra Wireless was ready
for an interview:
IoT and M2M applications that require low data rates, re-
quire long battery life, cost-optimized, or operate in remo-
te and inaccessible locations. They are easy to implement
and extremely useful for a number of vertical markets
such as manufacturing, wearables, utilities or transporta-
tion. Analysts expect up to five billion LPWA connections
in 2020. As early as 2018, about one billion US dollars are
expected to be generated.
What exactly is LPWA?
The term LPWA includes standardized cellular technolo-
gies such as LTE-NB1/M1 as well as proprietary wireless
technologies such as LoRa or Sigfox. LPWA solutions are
complementary to short-range technologies such as
Bluetooth, Bluetooth Low Energy, WiFi or Zigbee. LPWA
networks support devices that require lower mobility, low
power consumption, high range, low cost, and security.
Depending on the LPWA technology, these advantages
are combined differently. Among other things, it depends
on the specific application, which variant is most suitable.
Is it already foreseeable which LPWA technology will
prevail?
At the moment there is no clear answer to the ques-
tion, which technology will be implemented. No less
than seven different technologies will be discussed. The
benefits and success of LPWA technologies are certainly
undisputed. In the end, however, some will only serve
niche markets with limited applications. A decision for a
LPWA –
THE NEW
DIMENSION
FOR IOT
»LPWA makes the next big leap into
the Internet of Things and thus into
an even more connected world,«
says Joachim Dressler,
Board Member Finance of the M2M Alliance.
The Internet of Things is constantly evolving. The latest
keyword is called Low-Power Wide-Area, LPWA. What is
the technology suited for?
Low-power wide-area technologies enable the next big
leap into the Internet of Things and thus into an even
more interconnected world. LPWA networks are ideal for

technology requires careful consideration in order to avoid
making a mistake. Which technology is the most approp-
riate option depends ultimately on the respective project.
There are also good reasons for licensed technologies such
as LTE-M1, LTE-NB1, or ECS-GSM-IOT in combination with
one of the many global carrier networks, such as a private
network based on RMPA, Sigfox or LoRa technology. That
is why we have prepared a neutral overview of the indivi-
dual technologies that can be found on the M2M Alliance
website.
Can you give a concrete application example how LPWA
can be used?
The number of regions suffering from chronic water de-
ficiency is growing strongly. The United Nations assumes
that in the year 2025 1.8 billion people will have to live
with water scarcity. Smart water management solutions
that use the Internet of Things can help to counteract this
trend. It allows resources to be monitored, as well as the
production, storage, transport and use of drinking water.
For example, sensors in water pipes can help to locate
blockages, leaks or pipe breaks more precisely and more
quickly. Sewage sensors that detect bacteria and viruses
could help prevent epidemics. Effective water and sewage

management in both urban and rural areas has never
been more important than today. One does not even have
to think about developing countries. Smart water manage-
ment based on LPWA technology can make a big difference
here. Here, for example, the advantages of optimized power
management and deep coverage are utilized.
Why is the market not further developed so far, although
it would be possible from the technical point of view?
Historic 2G technology is neither network-optimized nor
the modules are energy-saving. Current 3G or 4G mo-
dules have been developed to support high-bandwidth
applications. This can sometimes even stream HD videos.
However, many IoT solutions only need to transfer small
amounts of data. Thus, the previously common wireless
modules always have a disadvantage. Here, new LPWA
technologies make much more sense, which can also be
tailored to the application. In the future, thanks to LPWA,
more utilities and other industries will put their trust
in the Internet of Things. LPWA‘s network expansion is
progressing faster than any prior technology introducti-
on - but it also takes time to provide stable commercial
services..

PROTOTYPING AND MAKER THINKING AS KEYS TO
SUCCESSFUL DIGITIZATION
Digitization is neither a myth nor empty buzzword bingo.
It radically transforms and disrupts our economy, and
virtually no industry remains unaffected by it – be it logi-
stics, automotive, healthcare, tourism, insurance compa-
nies, the financial sector or public administration.
Digitization is all about leveraging the power of advancing
technology to develop new, previously unimaginable, so-
lutions for old and new problems. For product managers
who are keen to develop an excellent digital product, this
is both a curse and a blessing: On the one hand, there
are no limits to their imagination. On the other hand, it
is no longer possible to pin down the characteristics of a
marketable product. Successful solutions can no longer be
designed, they must be discovered.
Business models always need to adapt and evolve conti-
nuously. What is different with digitization, though, is that
many complex factors are involved: Changing customer
expectations and needs, fast and highly available tech-
nologies as well as an ambitious startup community are
increasingly challenging classic business models.
Yet this is a revolution from which everyone can emerge as
a winner – by minimizing the time between idea and fee-

NARROW BAND IOT AND LTE CAT M1 ARE LEADING
THE WAY
LPWA technologies are starting to play the leading role in
IoT connectivity. Nonetheless, they still vary in terms of the
provided network coverage, data rate, current consump-
tion, safety/security, scalability, and interoperability. When
selecting the right technology for the job, it is essential to
consider the exact requirements of the respective applica-
tion in advance. Whatever the project, ideal modules are
always available from Rutronik and the German wireless
experts also help customers choose the correct solution.
SIGFOX AND LORA
Generally speaking, a distinction is made between licen-
sed and unlicensed technologies. The best known unlicen-
sed ones are SigFox and LoRa. Besides many other things,
they offer a cost advantage: The modules are cheaper and
do without a SIM card, meaning there are no additional
costs for managing and replacing it. Their biggest short-
coming however is the still incomplete infrastructure. As a
result, only licensed technologies are applicable for appli-
cations that demand blanket coverage and a reliable wire-
less connection. By utilizing the mobile network, they offer
better scalability, service quality, and security features.
NARROW BAND IOT (NBIOT OR CAT NB1)
In terms of the two licensed LPWAN standards, NBIoT
and Cat M1, NBIoT offers the lowest transmission rate: For
downloads and uploads it is below 250kbps and 20kbps
respectively. The bandwidth is 200kHz. NBIoT is therefore
basically intended for stationary applications with particu-
larly high energy efficiency requirements.
Network operators in Europe and Asia are busy promo-
ting the NBIoT standard; Deutsche Telekom is rolling
out extensive network coverage in Germany and across
Europe. In the USA, the emphasis is on Cat M1, while both
standards are supported in Canada and Australia.
For instance, Telit offers the NE910C1 module for NBIoT
applications. It combines top level energy efficiency with
particularly reliable network coverage, even in buildings.
It is therefore ideal for smart metering, security, point
of sale, and medical applications. Due to its xE910 form
factor (28x28mm2), it can be used easily to replace other
modules with the same form factor in existing applica-
tions. Moreover, thanks to its even smaller xE866 form
factor (19x15mm2), the NE866B1 module from Telit is the
perfect choice for very small devices.
LTE CATEGORY M1 (IN SHORT CAT M1 OR LTE-M)
With up to 1Mbps, the Cat M1 standard offers a higher
data transmission rate than NBIoT. In contrast to NBIoT,
Cat M1 also supports Voice over LTE (VoLTE) for appli-
cations with voice transmission. Handover from one cell
to the next also makes it ideal for cellular and mobile
applications such as telematics and fleet management
solutions.
In addition, Telit offers IoT modules for Cat M1. The
ME910C1 and the ME866A1 have the same form factors
as the NBIoT modules. Dependent on the country and the
supported wireless technology, the appropriate module
can thus be applied in a device without the need for a
costly redesign.

TODAY’S DEVICES AND MACHINES PRODUCE HIGH-
VALUE DATA. FOR EXAMPLE, A PRODUCTION MACHINE
LOGS AT WHICH TIME IT IS USED. HOWEVER, THE AVAI-
LABLE DATA ONLY BECOMES VIABLE IF IT CAN BE PRO-
CESSED AND USED TO IMPROVE A PRODUCT, TO OFFER
A SERVICE, OR TO REDUCE THE COSTS. FOR EXAMPLE,
KNOWING THE UTILIZATION OF PRODUCTION SYSTEMS
CAN BE USED FOR OFFERING OVERCAPACITIES OF THE
PROCUTION SYSTEM TO OTHER PARTIES. CURRENTLY,
THE VALUE OF THE AVAILABLE DATA IS LOST AS THE
DATA IS LOCKED WITHIN ITS SOURCE.
Communication enables remote accessing to and proces-
sing of the data. Internet-based smart services enable new
business cases, like production as a service, which mine
the value of the available data. A prerequisite for smart
services is that devices, machines, and smart services
exchange data in a secure way. Otherwise, data, machines,
and devices might get compromised or the value of the
data is monetarized by external parties.
Device and machine builders must ensure the data inte-
grity and the data confidentially. Furthermore, they must
guarantee that the sovereignty of the data remains to the
data owner. Currently, many devices and machine builders
struggling with these security challenges. Thereby, they
give away the ability to use the data to improve their own
products, services, and to reduce their costs. Nevertheless,
the information to build secure solutions already exists
within the M2M Alliance and the OPC Foundation (OPCF).
For this reason, the M2M OPCF user group has been
founded in order to document and spread best practices
for building secure communication solutions and smart
services based on device and machine data.

1. INTRODUCTION
Today’s devices and machines produce high-value data.
For example, a production machine logs at which time it
is used. However, the available data only becomes viable
if it can be processed and used to improve a product, to
offer a service, or to reduce the costs. For example, kno-
wing the utilization of production systems can be used for
offering overcapacity of the production system to other
parties. Currently, the value of the available data is lost as
the data is locked within its source.
Communication enables remote accessing
to and processing of the data. Internet-based
smart services enable new business cases,
like production as a service, which mine the
value of the available data. A prerequisite for
smart services is that devices, machines, and
smart services exchange data in a secure
way. Otherwise, data, machines, and devices
might be compromised. Date may be eaves-
dropped, and the value of the information
might be monetarized by malevolent parties.
Fig. 1 shows a typical use case for a connec-
ted factory. OPC UA is the choice for a secure
solution of this use case, so that device and
machine builders can ensure the data integ-
rity and the data confidentially. Furthermore,
they must guarantee that the sovereignty of
the data remains to the data owner. Current-

ly, many devices and machi-
ne builders are struggling
with these security chal-
lenges. Thereby, they give
away the ability to use the
data securely to improve or
extend their own products
and services or to reduce
their operational costs.
For this reason and ba-
sed on their expertise, the
M2M Alliance OPC Foundation security user group was
founded in order to document and inform about best
practices for secure communication solutions and smart
services based on device and machine data.
This article gives a condensed overview of the recommen-
ded security measures, which are used in »best practice«
installations.
2. OPC UA SECURITY MODEL
Security is an elementary requirement for OPC UA and it
is therefore integrated into the architecture. UA security
mechanisms are based on a detailed analysis of security
threats. UA security deals with authentication of users
and UA applications, integrity and confidentiality of the
exchanged messages, and the validation of function
profiles. UA Security complements the preexisting security
infrastructure within a company. Fig. 2 shows the scalable
UA security concept. It consists of the three levels: user
security, application security, and transport security. The
mechanisms of UA user level security grant access for a
specific user and its role while setting up a new session.
UA application level security is also part of the communica-
tion session and includes the exchange of digitally signed
X.509 certificates. Application instance certificates that are
exchanged during Secure Channel establishment are used
to authenticate an application. The supported UA security
profile that can be certified by the OPC Foundation defines,
which security mechanisms a UA application supports.
Transport level security can be used to sign and encrypt
each message during a communication session. Signing
ensures the message integrity and encryption prevents
eavesdropping.
The UA security mechanisms are realized as part of the UA
stacks, i.e., they belong to the software package prepared
by the OPC Foundation, so that the UA applications just
have to use it.
3. OPC UA SECURITY ARCHITECTURE
The OPC UA security architecture addresses the following
concepts:
• It envisages trusted information following the so
called CIA triad:
• Confidentiality by encrypting messages on the
transport layer
• Integrity by signing messages on the transport layer
• Availability by restricting the message size and
returning no security related codes
• It provides access control with the help of an
AAA Framework:
• Authentication by username and password or
X.509 certificate on the application layer
• Authorization to read, write values of a node or to
browse the information model based on the access
rights of the information model, access rights of the
user or of the user‘s role
• Accounting by generating audit events for security
related operations
However, the following concepts are outside scope of the
OPC UA security architecture:
• organizational issues, like security training of personnel,
security lifecycles and policies or how to handle physical
access. OPC UA does not replace the information security
management system (ISM) that the ISO 27001 defines.
OPC UA security aspects should be used to implement
security in depth.
• user and role authentication and authorization
management
Nevertheless, UA can be integrated with existing
concepts, like Kerberos, OAuth2, or JSON Web Token
by using claims-based authentication.
