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.5 06/2019

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.
