More Than 20 Billion Connected Devices Expected by 2020
Satellite plays a major role in supporting the growing requirements
of the Internet of Things and Machine to Machine (M2M), serving
the vast number of connected
devices in remote and difficult to
reach areas.
For many years, satellite has played
a vital part in Supervisory Control
And Data Acquisition (SCADA) and
M2M connectivity for oil and gas
pipelines, smart grids, environmental monitoring and more. As
the number of connected devices continues to grow significantly
- bringing operators the benefits of increased operational
efficiencies - satellite will remain an essential tool for providing
connectivity to remote locations.
By offering an extremely cost-effective terminal as part of a
scalable network solution, value can be provided for operational
managers in the fields of earthquake monitoring facilities, oil
and gas infrastructure, utilities, transport, energy distribution and
environmental monitoring anywhere in the world. The advent
of large scale renewable energy facilities like windmill parks in
inhospitable areas can benefit from a SCADA network to optimize
efficiency of energy generation and transportation.www.newtec.eu

How to monitor and control your business operation in the most
cost-effective way.
Rev.3 03/2017
Newtec Dialog® provides the means to establish an “always-on”
two-way IP connectivity between a Remote Terminal Unit (RTU) and
the Internet or a private network, therefore remaining completely
independent from existing terrestrial networks.
The basic IP connectivity is extended with Quality of Service (QoS) in
forward and return, allowing the deployment of real-time services.
The system consists of a hub that can support thousands of
remote terminals with a variety of service levels.
The hub contains management functionalities to monitor,
configure and control remote sites in large geographical areas.
Individual service configurations can be configured to meet
specific requirements of a remote site.
To make satellite an attractive alternative for SCADA, the Newtec
terminal implements the most bandwidth efficient technologies,
such as DVB-S2X ACM forward link, 4CPM adaptive return link
and embedded IP traffic enhancement software.

Confidentiality of exchanged information is guaranteed. Data
can be directly communicated to the RTU using a single satellite
hop. The communication end-points are authenticated which
increases the security of the SCADA network.
Since the encryption is fully integrated in the system, it can be
combined with traffic acceleration and compression, resulting in
real-time network behaviour comparable to traditional delivery
networks.
Newtec’s simple, yet very efficient implementation of ACM
Newtec’s simple, yet very efficient implementation of Adaptive
Coding and Modulation (ACM), doubles satellite throughput and
customer satisfaction by providing 100 per cent link availability.
ACM technology is incorporated into the DVB-S2X standard,
providing significant increases in bandwidth efficiency for satellite
applications and allowing modification of modulation parameters
of a satellite signal during almost any form of interference, without
interrupting the transmission or losing data.
Since rain fades are statistically short and happen quite rarely over
time, higher modulation parameters can be used most of the
time. However, when SCADA requires a fixed transmission rate or
a permanent high availability, the ACM technology ensures that
the fade only affects one of the services. This mechanism gives
the platform extremely high availability at no additional space
segment cost.
Depending on the instant need at a certain location the required
capacity can be varied. The Newtec VSAT platform is capable of
dynamically allocating capacity over the different remote
sites.

The hub provides redundancy on all layers (user, control,
management) and equipment. It has redundant RF signal
and mains supply inputs. The redundancy is conceived as
two fully redundant chains.
When there is a failure, an automatic switch over to the other
chain is performed. Even during service windows there is limited
downtime since upgrades can be performed on one of the chains
with the other chain active in a previous version. A failure in the
front-end is resolved by switching to the alternative RF input.

The Newtec VSAT platforms support services ranging from
data-only to voice and video. For many SCADA applications,
adding video will provide extra information when abnormal
events are detected. Integrating video traffic in the SCADA
network will improve operation efficiency by providing
greater insight into events, thus diminishing the potential
for damage caused by emergency events.
The Newtec VSAT platforms support the highest amount of
terminals active with real-time response behaviour.
This system feature enables users to deploy large amounts of
terminals on a minimal hub estate.
The modular and scalable hub allows users to start with a
small scale installation, expanding it by means of a software
license and gradually adding additional modules as the
network grows or applications are added. The unique “pay
as you grow principle” matches the inherent changes in size
or capacity of the network with a flexible investment model.

The Newtec VSAT platforms
provides seven classes of services.
Each of those traffic classes has
specific transportation and shaping
characteristics. This allows to define
a matching QoS for the different
traffic flows.
The real-time traffic classes assure
that delay and jitter performance are controlled even in
fading and congested conditions.
In a typical SCADA scenario, the critical data class would be
used for the monitoring and control traffic requiring a consistent
low latency.
The real-time classes would carry the video traffic that was
triggered by an alarm or an operator request. It is guaranteed
that this traffic would not interfere with critical SCADA traffic. The
real-time classes can also be used for local technician service
calls. The best effort class is then used for carrying on-site
internet or intranet access.
Versatile Service Guarantees
Take advantage of the real-time service class to view images of a guarded zone and permit the verification of false alarms.

Newtec VSAT platforms can be operated as a single service
provider platform or a multiservice provider platform. The
latter gives the opportunity to start a service without investing
into a full system.
The installation of the terminal can be done without any
specific training. This means a correct and fast installation
can be performed by a local technician of the remote site
with no need for special equipment. The local technician
is guided to perform the correct antenna pointing by the
Point&Play© tool. The terminal comes pre-configured so no
on-site administration is required, resulting in fast and risk
free deployment.
The terminal only consumes 20W typical and the DC power
supply fits alternative power sources like solar cells.
The low power consumption of the terminal finds its
origin in the interactive LNB. It has a simple upconversion
architecture and uses saturated power amplification
without any performance penalty.
