White Paper
CHANGE IS INEVITABLE, PROGRESS IS POSSIBLE
by Koen Willems (Market Director) and Jo De Loor (Product Manager)Newtec cy
Technological innovations, socio-political dynamism and economic uncertainty are quickly changing the satellite communications market as we know it. High Throughput Satellites (HTS), efficiency-increasing technologies, mobility, competition from terrestrial services, the quick uptake of new technologies (OTT, smart phones, 4G, HDTV, UHDTV 4K) and initiatives to decrease the digital divide are only a few drivers that catalyze the change in the satellite market environment.
Improving agility and increasing adaptability to market and technology changes, are two key requirements for the satellite service providers to successfully operate their business. The fulfillment of these requirements, in combination with the extension of their service portfolio offering, will lead to profitable growth.
When business strategy and tactics are built on the foundations of agility, adaptability and service portfolio extension, the satellite service provider requires an advanced satcom transmission platform. Such a transmission platform has to embrace the quickly changing business environment while also taking care of efficiency, reliability and quality of service. As such the satellite platform must be flexible, scalable and efficient to support the different business models and applications.
This white paper describes the main characteristics and advantages of the Newtec Dialog® Platform and several of its key differentiating Newtec technologies. Those Newtec technologies include the brand new patented Mx-DMA™ (Cross-Dimensional Multiple Access) and HRC™ (High Resolution Coding), but also include field proven Newtec technologies such as FlexACM®. The Newtec Dialog Platform provides the satellite service operator with the scalability, flexibility and efficiency he requires to run successful operations over satellite.

Rev.4 09/2015
Creating New Business Opportunities for a Changing World of Satellite Communications
1
The Four Main Challenges in the Satcom Market Today … and TomorrowBefore focusing on the key differentiating Newtec Dialog
technologies, it is worth taking a step back and looking in
detail at the satellite market in context, including the challenges
satellite service providers and end-users are facing today… and
tomorrow.
CHALLENGE 1:
Users Expect Higher Speeds And
Higher Data Volumes
The satellite service provider needs to accommodate
increasing data rates and the growing volume of data. So why
are data rates and volumes increasing?
• There is growing media rich traffic (Video-on-Demand)
and a market push-pull effect for HDTV (High Definition
Television) and UHDTV (Ultra High Definition Television)
• More users are getting connected to the information
highway, not only through traditional telecom devices such
as computers and laptops, but increasingly through smart
phones and tablets. These devices can be hand carried
and are not as dependent on electricity power proximity or
availability, which is important in developing countries.
• There are more government initiatives in place to close the
digital divide, to educate people, to respond quickly to
emergencies and to gather intelligence from the field.
• Increasing machine-to-machine communications that are
using bandwidth-hungry sensors and sensors that must
always be connected.
The introduction of various new High Throughput Satellite (HTS)
initiatives and constellations are a direct response to cater for the
increasing data demand. But these measures are not enough;
the end-user today expects both to receive the data rates and
the quality of service level to fit his application requirements.
CHALLENGE 2:
Users Expect to Pay Less for More
While the users expectations for speed and data volume are
increasing, they expect to get this at a lower cost. The relentless
advances and competition from fiber and other terrestrial
and wireless infrastructures put pressure on both prices and
margins. Satellite service providers are therefore forced to
engineer and deploy new services that provide a higher quality
of service at a much lower operational cost compared to today.
CHALLENGE 3:
The Market and Technology Complexity Is Ever
Increasing
In recent years, the satellite communications market has
witnessed important changes both on the technology side and
on the value chain side. If you are not able to adapt to the rapidly
changing environment, your business will be bound to fail or face
serious challenges. Adapt or die. It is a blunt statement but not far
from the truth. Socio-political changes and economic uncertainty
are additional drivers of complexity. Obviously all of these drivers
are linked.
The introduction of HTS satellites is a major industry enabler
which is helping to improve speeds, to increase data volumes and
also to decrease the satellite transmission cost. The architecture
of most of the current HTS satellites is forcing satellite service
providers to access those satellites through a geographically
distributed network of gateways. This requirement clearly
increases the complexity for operating those networks.
Newtec DialogMarch 2014

How to Survive and Grow in aFast Changing Satcom Environment?
The introduction of the first HTS satellites over North America
was not triggered by the ‘historical’ satellite operators, but
was the result of a few technology vendors who drastically
changed the business value chain by becoming both satellite
service provider and operator. Suddenly several satellite service
providers saw their technology provider becoming one of their
biggest competitors.
The good news for the satellite service providers is that the
historical satellite operators have started launching new HTS
satellites that stick to their traditional role of providing space
segment only. Satellite service providers can thus revert to
buying bandwidth capacity on HTS beams that are of interest to
their business offering.
As the business environment becomes complex the pitfall for
many service providers is to build their services on equally
complex infrastructures that have organically grown over time
along with their business. These platforms become difficult
to manage and operate and have a heavy impact on both
operational and capital expenses. Small changes to improve
operational efficiency, or to satisfy the customer, prove to become
very hard when having different technologies, topologies and
platforms on top of each other.
CHALLENGE 4:
Connectivity Anywhere Anytime
Last but not least satellite communications need to serve
users not only at home or in the office, but also when they are
travelling or on assignment in a remote location. People are
getting used to the fact that they can be reached and have
connectivity anywhere anytime. They expect to be able to get
access to the Internet on trains, planes, on ships and even in
their car.
Faced with massive changes in the satellite communications
environment it is key for business strategies to embrace change
in order to survive and capitalize on frequent alterations.
Guidelines for Survival and Growth
• A key strategy element for satellite service providers is to
be ready to adapt to new market opportunities. Agility and
a short response time are critical to survival and growth.
• Invest in satellite communication technology and flexible
and scalable platforms that can cope with these altering
situations.
• Differentiate service definitions and service packages from
competition
• Do not put all your eggs in one basket. By applying a
multiservice offering from a single hub the service provider
spreads the risk and can allocate the bandwidth to match
the changing market demand.
• Understanding the requirements of the different
applications and user profiles is absolutely critical. Apply a
specific comprehensive SLA scheme to fit the needs of your
different customers.
• Maximize profitability by introducing technology to the
satellite network that optimizes network efficiency and
service speeds.
• Deploy a platform independent from any satellite
constellation or satellite frequency in order to quickly adapt
to other satellites if the business or customer base changes
• Select a platform that grows along with your business and
that allows investment in a modular way when opportunities
arise.

The First Line of Defense
to Embrace Changing Business Environments
Based on the feedback of customers and taking the above
variable market conditions and guidelines into account, Newtec
has developed a platform that is capable of coping with changing
business environments in the satellite market. Moreover this
platform empowers satellite service providers to engage into
successful business models and efficient operations.
Newtec Dialog® is a scalable and flexible
multiservice satellite communications
platform that allows satellite service providers
to build and adapt their infrastructure easily
as their business and the satellite market
grows. Newtec Dialog will secure the future
of operators, giving them the power to offer a variety of services
while making hassle-free decisions on the technology to use.
The New Platform is based on three core principles that have
been executed all through the architecture, the supporting
technologies and implementation of the platform. The main
principles are Flexibility, Scalability and Efficiency.
FLEXIBILITY
Newtec Dialog is built for flexibility. Whether the satellite service
provider addresses a single application or multiple markets,
Newtec Dialog offers customers optimal technology without
compromising. This produces a multitude of possibilities for
optimizing the usage of infrastructure and satellite capacity for
different markets.
As an example, an operator with a history of mainly servicing
broadcast clients can easily add new services and begin
targeting cellular backhaul and trunking, consumer & enterprise,
VSAT or government markets using the same Newtec Dialog
infrastructure. Newtec Dialog easily adapts to any business needs
and goes hand in hand with delivering tailored services.
SCALABILITY
The platform scales to every type of satellite network: from small
networks, with 5 remotes, up to the largest networks, having
hundreds of thousands remotes, from single coverage to multi-
spot High Throughput Satellite networks.
Additionally, satellite service providers can invest as the business
grows, the HUB scalability and flexibility enables low up-front
CAPEX. The platform connects a variety of Newtec’s modems that
can be easily adapted for different applications depending on the
business evolution.
EFFICIENCY
Efficiency is defined both at the operational and technology
level in the Newtec Dialog platform. It provides the extra
bandwidth, throughput or savings satellite service providers are
craving for. Additionally it will allocate every bit to the designated
user and provide the highest number of customers per MHz at
maximum availability in order to meet the toughest Service Level
Agreement Requirements.
Newtec Dialog assists the satellite service provider to select the
best transmission technology for their particular application.
For the return link technology they can opt for the flexibility of
MF-TDMA (Multi-Frequency Time-Division Multiple Access), the
efficiency of SCPC (Single Channel per Carrier) links or the best
of both worlds, the patented and brand new Mx-DMA™ (Cross-
Dimensional Multiple Access) HighResCoding™ technology. This
revolutionary technology fills the gap between the MF-TDMA and
SCPC return technologies.
The Newtec Dialog platform combines the efficiency of the
forward and return satellite links with Newtec core technology
such as FlexACM, Bandwidth Management and Cross Layer
Optimization. With these technologies, Newtec Dialog is able to
provide the most optimal modulation and bandwidth allocation,
while guaranteeing the highest efficiency and availability.
Newtec DialogMarch 2014

Today’s satellite service providers interact with many different
communication technologies across a broad range of platforms.
The operator, satellite service provider and end-users all expect
to receive the data rates and the quality of service level to fit
their application requirements.
The key for the satellite service provider here is to fully understand
the business or the operation of his or her customers and to
provide services according to the nature of these applications.
A good approach is to draft different user profiles (per market,
application or segment in the value chain) based on typical
satcom usage, priorities and performance attributes. A typical
user profile will look at the following performance attributes:
• Data Throughput
• Availability (SLA)
• User Experience
• Cost
• Ease of Use
• Efficiency
• Performance
• Product/Application Fit
Different applications and markets have different needs. The
user profile and performance attribute expectations of a home
user with Internet access over satellite will be entirely different
from a broadcaster. For the broadcaster, not losing the satellite
link for a live sports video feed will have priority over pricing,
whereas ‘assertive’ consumer VSAT users tend to switch service
providers quickly if they are not happy with the user experience
or pricing.
The strength of the Newtec Dialog platform is to be able to
combine different applications and user profiles on the same
platform, which results in massive efficiency gains as well as
cost savings. Moreover bandwidth allocation can be shifted
amongst the different applications depending on the business
opportunity or the mission at hand. The Newtec Dialog Platform
currently covers the following markets and applications:
• Consumer, SME and Enterprise VSAT Networks
• Cellular Backhaul and Trunking
• Fixed Video Contribution and Video Exchange
• Satellite News Gathering
• TV and Radio Distribution to Towers and Head-Ends
• Civil, Government and NGO Networks
• Disaster Recovery and Emergency Networks
• Intelligence, Surveillance & Reconnaissance (ISR) and
Border Security
• SCADA and Surveillance Networks

Four Building Blocks for a Successful Satellite Platform
BUILDING BLOCK 1:
A Scalable Platform Enabling Both Small Single Service
and Large Multiservice Networks
The Newtec Dialog Platform strongly relies upon four building
blocks that further define the Newtec Dialog solution. These
building blocks are the multiservice approach, the innovative
technologies, the different product combinations and the ability
to support various business models.
The Newtec Dialog Platform can easily be compared with the
‘Smart Grid’ concept as being defined in the energy market. Within
the Dialog Platform the basic principles (Flexibility, Scalability &
Efficiency), the 4 building blocks and the related markets and
applications are interconnected. This system allows for smart
monitoring, analysis, control, change and communication within
the platform to help improve efficiency, reduce cost and maximize
transparency and reliability of the entire satellite network.
The Newtec Dialog Platform embeds the flexibility to address
both small single service networks as well as larger multiservice
networks. Even if the satellite service provider wants to start up
with a small network and a CAPEX-friendly investment, he still
has the opportunity to add extra services at a later stage and
grow his business from the same platform.
Multiservice networks provide more than one distinct
communications service type over the same physical infrastructure.
Multiservice implies not only the existence of multiple traffic
types within the network, but also the ability of a single network
to support multiple applications without compromising quality
of service (QoS) for any of them. The following traffic types are
supported under the Newtec Dialog Platform:
• Video and Audio (Transport Stream and File-Based)
• Data
• Voice
• Datacasting (unicasting & multicasting)

All these traffic and service types are auto-dynamically
controlled through different prioritization and classification
schemes inside the Dialog NMS in order to optimize the
throughput according to the available bandwidth in the
adaptive satellite network.
For example, a satellite service provider today hosts a
consumer VSAT network on his Newtec Dialog platform.
When launching a consumer VSAT service the uptake by
users might take a while. The remaining bandwidth in the
meantime can be used for servicing a cellular backhaul
network. If an opportunity were to arise for the satellite service
provider to expand his business by offering video exchange
services for the local broadcaster, he can launch this service
from the same hub, whilst still respecting the specificities of
the broadcast business.
BUILDING BLOCK 2:
Innovative Technologies that Save the Day
The Newtec Dialog platform integrates innovative and
revolutionary technologies that will take the satellite world
by storm. Newtec introduces the world premiere of a new
waveform called HRC as well as a new return access technology
that fills the gap between MF-TDMA and SCPC, the Newtec
patented Mx-DMA. Those technologies are bolstered with
proven Newtec technologies including FlexACM, Bandwidth
Management and Cross Layer Optimization.
The combination of the technologies serve the overall
Newtec Dialog platform principles on Flexibility, Scalability
and Efficiency and solve bandwidth issues, provide excellent
quality of service and manage the availability of the satellite
link.
Cross-Dimensional Multiple Access (Mx-DMA)
Return Technology
Three modes of return technology are available to the
satellite service provider on the Newtec Dialog Platform
to configure his network: MF-TDMA, SCPC and the new
patented Mx-DMA (Cross-Dimensional Multiple Access).
MF-TDMA satellite return technologies typically target
applications with highly overbooked and bursty traffic
services, such as Internet access for consumers, SME, B2B
and SCADA networks. SCPC on the other hand has more
applicability in high data and video rate return links. In
between there are a large number of applications with low to
medium overbooked services and throughput rates up to 20
Mbps where it can be difficult to chose between either SCPC
or MF-TDMA. These applications are enterprise/corporate
networks, government/NGO networks, cellular backhauling
and low to medium rate broadcast contribution networks.
Some technologies in the market already allow a (semi)-
dynamic switch between SCPC and MF-TDMA, but that goes
hand in hand with a considerable satellite link outage time ,
packet loss and sub-optimal usage of the link.
Newtec DialogMarch 2014

Ultimately the end-user does not really care about the type
of return technology behind his satellite service, rather that it
provides the data, user experience and the quality he or she
expects. This is where Newtec’s Mx-DMA comes into play.
Newtec Mx-DMA is the return technology that incorporates
the best features of MF-TDMA and SCPC technologies and
at the same time solves the difficult choice to select one or
the other.
The Mx-DMA return technology on the Newtec Dialog Platform
adjusts the frequency plan, the symbol rate, the modulation,
coding and power in real-time for every terminal in the satellite
network. These adjustments are based on the return traffic
demand, the network QoS management and channel conditions
for the terminal population in the network. Within the Mx-DMA
return link each carrier is assigned to only one terminal. As such
SCPC-like maximum return efficiencies are achieved.
At the same time the flexibility of MF-TDMA can be maintained. It
remains possible in Mx-DMA to allocate bandwidth on demand
and in real-time. In other words as the traffic demand for a remote
terminal is changing, bandwidth will be allocated on the fly. If
the traffic within the terminal becomes more important, extra
bandwidth will auto-dynamically be assigned to the carrier inside
the link based on QoS and priority rules. The entire operation is
performed seamlessly without any data packet being lost.
The implementation of Mx-DMA typically results in a doubling
of the transponder throughput using the same bandwidth, or
alternatively reducing the required space segment capacity by
50 percent. The new technology also ensures low jitter and delay,
perfect for applications like voice and streaming video.

High Resolution Coding (HRC)
Next to the Mx-DMA return technology, Newtec Dialog
introduces a new highly efficient and patented waveform called
HRC or High Resolution Coding technology. The innovative
next-generation waveform is typically applicable for low to
medium rate applications between 32 kbps and 22 Mbps. HRC
has an efficiency comparable to DVB-S2 with a 5% roll-off factor
(see figure 4) in order to get as many bits through the available
bandwidth as possible.
In contrast to DVB-S2, the HRC coding also handles low
throughput speeds in SCPC mode without the harmful latency
effects that could hamper voice traffic or video streaming services.
HRC optimizes low to medium rate traffic and avoids latency
over satellite by using short block codes. The high granularity
of MODCOD choices (40 MODCODs from QPSK to 32APSK)
provides the best modulation and coding per link. In combination
with ACM (Adaptive Coding and Modulation) the most efficient
mode is selected automatically depending on the available
bandwidth and instant satellite link conditions.
The line chart below (figure 5) demonstrates the efficiency of the
three optional return link technologies on the Newtec Dialog
Platform: Newtec S2 Extensions for high speed SCPC links (blue
line), the Newtec HRC coding and modulation (orange line) and
4CPM coding and modulation (green line) performance used for
MF-TDMA. Comparing the HRC and MF-TDMA efficiency results
there is an average efficiency gain of 60%. At the higher signal
to noise ranges (C/N) it will even exceed 100% efficiency gain.
The Mx-DMA technology combines the highly efficient HRC with
real time variable bandwidth allocation equivalent to MF-TDMA.

FlexACM®
The Newtec Dialog Platform also integrates the well-known
and field proven FlexACM® technology. Even in harsh and
hostile conditions it is important to have networks over satellite
available at all times and not to lose data. Not only to fulfill
the most demanding SLAs but also to assure mission critical
communications. The unique auto-adaptive technology
incorporated inside Newtec’s FlexACM® takes care of any fading
condition in order to avoid link or data losses. Fading conditions
due to choice of satellite (Inclined Orbit Satellite, Ku-, Ka-, X-band,
HTS), environment (rain & dust), shadowing effects or interference
(between two adjacent satellites) will no longer interrupt satellite
transmissions.
FlexACM® combines adaptive coding and modulation (ACM)
with Newtec’s noise and distortion estimation technology (NoDE)
and predictive fading technology on upcoming fading variation
(ThiMM – Thin Margin Manager) to get as close to the zero margin
limit as possible. In other words to make full use of the satellite link
at maximum service availability regardless of condition.
FlexACM is implemented for all forward and return link options
(SCPC, MF-TDMA and Mx-DMA) on the Newtec Dialog platform
and results in increased throughput or alternatively in important
bandwidth savings. Moreover it assures maximum availability
without link or data losses.
In combination with IP capacity sizing, bandwidth management
and cross-layer optimization technologies, FlexACM achieves
extra gains by implementing statistical multiplexing ‘in the
sky’ and overbooking ratios. As a result the highest number of
customers can be allocated per MHz without compromising the
end user experience.

BUILDING BLOCK 3:
Products That Match Your Business
The Newtec Dialog principles of Flexibility, Scalability and
Efficiency are reflected inside the platform infrastructure elements,
being the hubs, modems and network management system
(NMS). As Newtec Dialog covers different types of network for
various applications within the broadcasting, cellular backhaul,
Trunking, consumer and enterprise VSAT as well as government
markets, the platform offers a range of hubs, modems, and NMS
configurations to match the application requirements.
Newtec Dialog Satellite Hub Module
The heart of the Newtec Dialog Platform is the flexible and scalable
satellite hub module. The hub caters for small, medium-sized and
even large consumer VSAT-type satellite networks. Basically the
Newtec Dialog Hub module comes in two flavors depending on
different parameters: the size of the network, the amount and
type of services or applications that need to be addressed. The
Newtec HUB6501 is the compact 1IF market-entry sized hub
module designed for small satellite networks and for operators
that require a cost-effective solution to start up their services.
Thanks to its compact size the hub can easily be integrated in
existing NOC (Network Operation Center) infrastructures or at a
customer premises.
The Newtec HUB6504 on the other hand is the all-encompassing
and future proof 4IF hub module that offers the service provider
and satellite operators full access to the scalability, flexibility and
efficiency features of the Newtec Dialog platform. The Newtec
HUB6504 module fits different configurations from simple
1-satellite networks to multi-satellite or multi-gateway spotbeam
networks. A central Network Management System (NMS) system
controls multiple geographical dispersed hub locations, each
allowing access to multiple satellites.
Figure 6: The Newtec HUB6504 4IF hub module and the compact Newtec HUB6501 1IF Hub

The Newtec Dialog Hub Module includes the forward link, the
reception capabilities of different return technologies (SCPC,
MF-TDMA and Mx-DMA through multicarrier 1RU demodulators)
as well as the NMS, Traffic and QoS Management and Network
Optimization technology (Acceleration, compression, encryption
and datacasting). The modular design of the Hub allows the
satellite service provider to build their own platform according to
his or her needs.
The hub will grow alongside the business and can be adapted
quickly to react to changing environments. The satellite service
provider is able to target multiple services and applications with
the same hub module and allocate bandwidth, throughput and
SLAs through a single user interface. As such initial investment
and business risks are limited.
Newtec Dialog Satellite Modems and Terminals
A multiservice satellite platform has the need for a variety of
modems and terminal types to address the different applications,
throughput requirements and user profiles. The Newtec Dialog
platform includes three main modem families: the 2000-series,
the 3000-series and the 6000-series. The main differentiation
between the modem series’ in a technical sense is in the support
of different waveforms, return access technologies, throughput
rates and form factors. Core Newtec technologies such as
FlexACM and Clean Channel Technology (CCT) are implemented
on all modem types to make the most efficient use of the satellite
link. The modems are matched with characteristic application
requirements and can be combined on the same multiservice
satellite network connecting to a single Newtec Dialog Hub.
• The MDM2200 satellite modem typically addresses Consumer
VSAT, SOHO, SME and SCADA applications. The modem
has been designed around the concepts of easy installation
(Point&Play), low initial investment per user, efficient usage of
the satellite spectrum and maximized broadband experience.
The modem receives DVB-S2 signals up to 22 Mbps and
can easily cope with low roll-off factors (providing extra 15%
efficiency on top of the S2 link) incorporated in Newtec Clean
Channel Technology (CCT). For the return link Newtec’s 4CPM
is the selected MF-TDMA waveform technology with rates up
to 3,5 Mbps per unit. The MDM2200 comes with a dedicated
compact and cost-effective iBUC and antenna to reduce
investments to an absolute minimum.
• The 3000-modem series targets the mid section of the
satellite market and is generally deployed in Cellular
Backhaul, VSAT Enterprise, Broadcast contribution and
Government/NGO networks. These remotes require a wide
range of IP services including multi-casting, broadband
access and VoIP. The 3000-family has 2 versions: the
MDM3100 and the MDM3300 modems. The main
difference between the modems is in the waveform support
for the return technology. Next to the wide choice of Mx-
DMA, HRC SCPC and 4CPM MF-TDMA waveforms that
typecast both modems, the MDM3300 unit also supports
DVB-S2 and S2 Extensions in the return channel. As such
45Mbps download (DVB-S2 with CCT) and 20Mbps uplink
speeds can easily be achieved.
Newtec DialogMarch 2014
12
S2 Extensions is the successor to DVB-S2 and translates
into better efficiency, higher speed and improved service
robustness (see Newtec White paper: Demystifying S2
Extensions). When comparing the current DVB-S2 standard
against the full implementation of S2 Extensions (activating
5%, 10% or 15% Roll-Offs, advanced carrier filtering, 64
APSK, increased granularity in MODCODs) staggering
efficiency gains up to 37% can be achieved for professional
applications over satellite.
• The MDM6000 and the MDM6100 Broadcast modems
are the versatile DVB-S2/S2 Extensions units that combine
high efficiency features (including wideband up to 72
Mbaud) with innovative technology to maximize data
throughput and availability in networks sensitive to adaptive
satellite bandwidth. The powerful platforms give satellite
service providers the tools to support bandwidth hungry
Backhaul, Trunking, Broadcast, Exchange and Government
applications in their network. With the 6000 series modems
speeds from 1 Mbps up to 380 Mbps are available as return
towards the Dialog Hub through Newtec’s S2 Extensions
technology.

Newtec Dialog Network Management System (NMS)
The entire Dialog Platform is monitored, controlled and
configured through a fully integrated Network Management
System. The NMS gives the network operator a full suite of
element and network tools based on intuitive workflows and
an easy to use web-based graphical user interface (GUI). It is
designed to help service providers to become more efficient and
effective in creating, delivering and monetizing services.
The FCAPS framework is the core of the Dialog network
management with the following elements:
• Configuration management
• Fault & Performance Management
• Accounting
• Security
The versatility of the NMS configuration is fully in line with the
Dialog flexibility and scalability principles. Both Host Network
Operators (HNO) and Virtual Network Operators (VNO)
can co-exist on the same multiservice platform with different
access rights and tools to operate their network. As such the
service provider can easily integrate the management system
with the existing Business Support System applications (e.g.
billing, rating, customer-service, etc.) and Operation Support
System applications (e.g. service quality monitoring, network
performance, resource management). A central NMS system
controls multiple geographically dispersed hub locations, each
allowing access to multiple satellites.
The NMS includes an extensive set of Application Programmatic
Interfaces (API) available to HNOs and VNOs. These machine-to-
machine interfaces allow easy integration with OSS/BSS platforms
or enable integration into other higher-level NMS systems.

Newtec Satlink Manager
The optional Newtec SATLink Manager accompanies the
Newtec Dialog NMS for satellite resource allocation, reservation
and automated satellite link setup or teardown. The SATLink
Manager smoothly plugs into various NMS eco-systems for
smooth integration into customer environments.
Satellite service providers are now able to manage satellite
capacity and automate mesh and/or star based satellite links
between multiple remote satellite terminals and between
satellite terminals and a hub.
The SATLink Manager supports various use cases within the
satellite broadcast, VSAT, Government and IP Trunking/IP
Backhauling markets: from the reservation and setup of occasional
use satellite links to the management of satellite capacity defined
within one or multiple transponders and/or satellites. Moreover
the satellite capacity is optimized by determining the most
appropriate encapsulation and modulation scheme for a given
service.
BUILDING BLOCK 4:
Enabling various Business Models
With the service offering, the Newtec technology and the
accompanying Newtec Dialog infrastructure elements in place
the time has come to initiate the creation of successful Business
Models. The flexibility of the platform allows for the configuration
of the network and its elements into an existing business model.
However, the increasing competition from both terrestrial and
satellite solutions have an enormous impact on traditional
players in the satellite ecosystem. Fighting disruption or seeking
to maintain the status quo is ineffective and results in decreasing
profits for service providers.
In order to establish new sustainable business models service
providers should focus on exploiting the core competence of
operators, their flexibility to react to change, the capability to handle
multiple applications/services and an innovative network design.
The Newtec Dialog platform is the prime tool to cater for these
new and innovative strategies, business models and services.
The overarching goal of a business model is to address a business
opportunity in such a way that value is created for customers as
well as for the satellite service provider himself. Next to value
differentiation also needs to be taken into account: how does
the service provider, network operator or broadcaster distinguish
himself from competition. The core competences, value adds and
the interaction with the customer define the way satellite providers
position themselves in the value chain. The provider can stick to a
single activity or ‘verticalize’ their offer and fill different positions in
the value chain.

In the below (figure 9) example the wholesale business model
is described. In this model the Virtual Network Operator (here
an Internet Service Provider) has the choice to either resell a full
package of services coming from the satellite network provider or
to create his own value add by reselling bandwidth with his own
defined service package.
The inherent strength of the Newtec Dialog platform is that it
supports both traditional and innovative business models from
managed services to VNOs to multiservice and more. Moreover the
platform caters for a general business model applied for all services
and customers or different business model approaches depending
on the application, region, customer base or service itself.
The starting point is the user profile and the position of the satellite
service provider inside the value chain. From that point onwards the
network can be configured to maximize operational and satellite
spectrum efficiency. The following questions will certainly need
to be addressed during the deployment of the network: What is
the SLA and throughput required by the customer? Do they need
Peak Information Rates (PIR) or Committed Information Rates (CIR)
for their services? Are the services clustered in a package by the
Service provider? How many levels of service providers and VNOs
are present in the network. What is the overbooking ratio? What is
the optimal return technology per service. Do the services suffer
from adaptive satellite bandwidth?
The basic technologies behind the flexible Business Model
strategies are the advanced shaping rules, bandwidth management
and Quality of Service incorporated inside the Newtec Dialog
Platform.

Putting Newtec Dialog to the TestNow the theoretical concepts and the technologies behind the
Newtec Dialog platform are well understood, it becomes time to
put the platform to the test. In the following example, two use cases
based on a star topology satellite network of 20 terminals spread
over Sub-Saharan Africa will be demonstrated. In the example we
will mainly focus on the return channel technologies SCPC, MF-
TDMA and Newtec Mx-DMA.
The example satellite network (see figure 10) features following
Newtec Dialog Platform elements:
• Newtec HUB6501 1IF Hub Module
• Modems: MDM3100/MDM3300 IP Satellite modems
CASE 1:
Leased Line Services in Ku-band
In the first case the satellite service provider runs leased line services
for its customer. In the service level agreement between both
companies a dedicated throughput per site at 99,8% availability
in Ku-band has been determined. SCPC is traditionally selected
as the most optimal technology for leased line types of networks.
But how does it perform against the Newtec Mx-DMA technology
when we consider the return channels?

When implementing 20 separate return channels using DVB-S2
technology with a 20% roll-off factor and short frames, the total
occupied bandwidth for 18 Mbps throughput equals 12,44 MHz. To
achieve the dedicated service levels for SCPC DVB-S2 is required to
have terminals based on a 1.8m antenna and 8W BUC.
For the same 18 Mbps of dedicated throughput over the
leased lines Newtec’s Mx-DMA only requires 8,06 MHz satellite
bandwidth. In other words, by deploying Newtec Dialog and
the Newtec Mx-DMA return technology 35% savings can
immediately be generated for this leased line network.
We can even take the efficiency gains a step further by engaging
the full potential of Newtec’s Mx-DMA technology. In the
above sizing, each of the 20 sites gets the dedicated return
throughput according to its service profile, resulting in the total
aggregate capacity of 18Mbps in the return link. However, it is
very unlikely all the 20 sites are instantaneously using the full
service profile dedicated capacity. As a consequence operators
can apply a statistical multiplexing gain on the aggregated
capacity compared to the sum of the individual links (which is
also common practice in terrestrial networks). The statistical
multiplexing will not burden the end-user experience or the
service level agreements. Newtec Mx-DMA technology and its
on-demand bandwidth allocation fully supports the “statistical
multiplexing in the sky” feature.
For this leased line network a conservative 25% statistical
multiplexing gain has been considered for the 20 sites, reducing
the throughput from 18 to 13.5Mbps.
By implementing statistical multiplexing together with Newtec
Mx-DMA technology, the satellite service providers can realize
a 52% bandwidth saving, compared to DVB-S2, going from
12.44MHz to 6.02MHz satellite bandwidth.

CASE 2:
Shared Services in Ku-band
In the second case the service provider offers shared and
overbooked services in the return link over satellite for the 20
remote sites. The SLA provides 2 Mbps peak rate (PIR) for all
remotes and three types of committed information rates (CIR)
for the satellite network over a Ku-band transponder at 99.8%
availability. Traditionally MF-TDMA would be the selected
technology to handle these types of traffic. In this scenario we will
compare the MF-TDMA performance against Newtec’s Mx-DMA.
When selecting MF-TDMA as the technology for the return link for
the 20 remote sites running shared and overbooked services, a
total satellite bandwidth of 7.76 MHz would need to be allocated.
In this MF-TDMA network a 1.8m antenna and 4W BUC are put
into operation.
Alternatively Newtec’s Mx-DMA only requires 3,89 MHz to run
the same throughput for the same PIR and CIR services. As such
Mx-DMA, running on the Newtec Dialog platform, results in a
50% gain compared to MF-TDMA technology.
More Throughput, More Customers per MHz
Both use cases clearly demonstrate the Newtec Mx-DMA
benefits over SCPC and MF-TDMA as return technology. For
dedicated capacity services Mx-DMA HRC typically brings two
equally attractive options when compared to SCPC: save more
than 35% bandwidth or serve 54% more customers within the
same bandwidth. By applying statistical multiplexing together
with Mx-DMA the bandwidth gain will be increased to 52%.
For shared and overbooked services, the bandwidth saving of
Mx-DMA HRC is even more than 50%, equivalent to serving more
than double the number of customers in the same bandwidth.
