unlikely to survive the tsunami of calls that come after

it.”

Trends in Technology

Addressing your bottom line through the use of the latest

technologies

• DVB-S2 and DVB-S2x

• Adaptive Coding and Modulation

• Carrier Cancellation Technology

• Lower Roll off factors

• Multi-demodulator Hub Cards

21

DVB-S2 & Extensions

A new standard enables true convergence

• Excellent spectral efficiency:

• Up to 40% bandwidth saving compared to DVB-S

• Up to 2dB better than Turbo Codes

• HDTV enabler

• Unlike DVB-S, DVB-S2 is optimised for MPEG and IP

• Allows for DTH and DTT distribution in single carrier

22

Adaptive Coding & Modulation • Higher throughput for the same amount of resources

• When rain fade issues arise, the modulation can

adjust so as to ensure the remote stays in the

network

• Allows lower per Mbps price points to be achieved,

leading to more competitive prices in the market

Maximum achievable data throughput by utilizing the most efficient coding and modulation scheme at any moment in time, depending on location within the satellite contour, antenna size and atmospheric conditions

25

Multi-Demodulator Cards

• Multiple inbound carriers in one return card

• Reduces cost of equipment – fewer cards and less chassis space

• Potential to pay as you grow with existing hardware (only software

required)

• Ease of manageability

• Far more common today across various platforms

• Efficiency dependent upon location within the footprint

• Can Provide Significant Cost Savings • Pricing as low as $1,400 - $1,500/Mbps SK & $850 - $950 IOO

• Costs decline further when implemented with C-n-C

• Actual Customer Network • Original service engineered for 39/12 Mbps

• Actual throughput was 65/32 Mbps

• No additional MHz used!

29

An Epic Change

• Modem and ground technology improvements have played a

significant role in efficiency advances

• Ground infrastructure is only part of the story

• Satellite technology has also evolved

• The next advance is on its way…High Throughput Satellites

30

What are the Components of High Throughput Satellite

Design Decisions?

All of these components impact the business model for satellite

design and are driven by go-to-market business criteria

HTS

Throughput

Architecture

Spectrum

Efficiency

Coverage

31

Technical Element #1: Throughput

• Throughput is the speed of information delivery (bits/sec), driven by:

– Bandwidth (MHz) = The “size of the pipe”, increased by frequency reuse

– Efficiency (Bits/sec per MHz) = Amount of error-free content in the pipe

• Maximizing aggregate satellite bandwidth or maximizing individual user throughput are often

conflicting technical goals.

– There is a trade-off, and the right answer depends on the business applications

32

Technical Element #2: Efficiency • Efficiency is the amount of error-free information to the user (bits/Hz)

• Spot beams drive efficiency up (more power) but close proximity of same frequency spot beams increases

interference and brings efficiency down.

• Greater distance between same frequency spot beams will increase efficiency but reduce

frequency reuse and total satellite throughput. So what is best?

• This is a trade-off: Serving more users with consumer-grade quality (lower efficiency) or fewer users with carrier-

grade quality (CIR, higher efficiency). This is a decision that will depend on the operator’s business plan.

Four-color reuse Eight-color reuse

33

Why Does Efficiency Matter?

• Optimal satellite efficiency depends on the target

business application

– A lower efficiency design will optimize shared network

services for the most number of users at the lowest possible

cost per user

– A high efficiency design will enable carrier-grade services,

maximizing throughput delivered to specific end users for

mission-critical applications

• Greater efficiency lowers end-user terminal costs for

consumer and enterprise applications

34

Technical Element #3: Coverage

• The size of beams formed by a

standard satellite antenna size

depends on frequency

and

• The number of beams is constrained

by satellite resources (power,

mass, space)

• The size of the targeted coverage

is a major driver of frequency

selection

Open vs. Closed Architectures; Trade-offs Open architecture

Pros:

• Lets customers customize and add value to their

service offering

• Provides control and choice

• Ideal for selling to the sophisticated buyer via a

distribution network

Cons:

• Must have the network expertise to operate it on

their own

• May be more costly than closed systems

Closed architecture

Pros:

• Offers simplicity

• May be best option for simple applications where

cost is a factor

Cons:

• Provides little room for differentiation between

service providers

• Less control and flexibility

38

Technical Element #5: Spectrum

• HTS can be developed in any

frequency band

• The frequency selection is driven

by many considerations:

• Coverage and beam size

• Atmospheric conditions in the region that is

being served

• Availability of a robust ecosystem of ground

technologies

C

Ka Ku

39

Why Does Spectrum Matter?

• Business considerations for

spectrum selection decisions:

• End-user applications

• Geographic location of services to be

provided

• Coverage considerations

• Availability of back-up capacity

• Current investments in gateways,

terminals, systems and training

• Available frequency rights
