Connecting Africa by Satellite

• Satellite Provides Affordable and Flexible

Critical Network Infrastructure

– Limited capex requirements

– Investment in access equipment only

• Ubiquitous Broadband Connectivity

– 100% markets/populations covered today

• Highly Reliable Networks

– +99% network availability rates

– “No cable cuts”

• Flexibility Architecture

– Supports “thin route” consumer

connectivity to “thick route” commercial

applications.

• Enables eGov Initiatives

– eSchools, eHealth, eGov/ICT, cloud

services

– delivered to markets of all sizes today

• Global IP traffic is expected to more than double between now and 2015

• Global mobile data traffic will grow three times faster than fixed IP traffic

The Role of Fixed Satellite Services for

Connectivity Growth (2000-2012)

• Satellite options of today:

– Satellite was the first type

of access connectivity used

to connect Nigeria @ its

GSM launch in 2001

– Allow for rapid deployment

– Provide last-mile

connectivity required to

reach the most remote

locations

– Foster population welfare

and improved quality of life

– Provide resiliencies needed

to meet SLAs at edges of

hybrid networks

The Design: Technical Considerations for

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

Intelsat EpicNG:

• Can be leveraged in more

highly-populated areas

that demand more

bandwidth

• Provide a very low-cost

solution that can push a

mobile network’s edge

further into rural areas

• Provides the bandwidth

needed to backup high-

speed core/backbone

links.

Existing EpicNG

• Economical backup to

fiber/microwave links

towards the edge of a

network

• Provides increased

resiliency via a

redundancy option in

case of link failure

The Intelsat EpicNG platform complements existing FSS designs - a layered network approach matches proper design and economics to best meet a given set of requirements

Right Spectrum for the Right Application

• 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

The Right Result and Benefits

• Double or more increased in throughput capacity

• Ease to provide access to e-gov services in schools, council

offices e.t.c.

• Lower Opex costs with higher throughput

• Potentially leads to increase GDP for the country

• Lower Capex for remote terminals allows for greater reach

into rural and difficult to reach locations

• Better flexibility using C or Ku or Ka

• Better reliability and durability

Intelsat EpicNG will complement Intelsat’s existing fleet, providing a hybrid layered network solution. Attractive economics are achieved through proper

design to best meet a given set of requirements.
