Platform Tradeoffs:Ground Technologies for Spot Beam vs. Wide Beams

Satellite Innovations…

A high throughput satellite (HTS) is a satellite that has many times the throughput of a traditional FSS satellite for the same amount of allocated frequency on orbit.

These satellites take advantage of frequency reuse and multiple spot beams to increase throughput and reduce the cost per bit delivered, regardless of spectrum choice.

• CCTTM and BW Cancellation provide 485Mbps through 72MHz transponder (7 Mbps per MHz)

• iDXTM 3.0 with 2D16 provides both TDMA & SCPC return channels

• IPoSTM (DVB-S2 with ACM) on outbound teamed with AISTM (MF-TDMA with LDPC) on inbound

• Advanced VSAT provides DVB-S2 outbound with ACM and VersaFEC® return channel

• SkyEdge II-c incorporates 1.1 Roll-Off factor, supporting 66 Msps and 250 Mbps per Carrier

Operating Expenses


Teleport Operations

Space Segment

• Satellite access antennas

• Hub antenna costs are a large cost

element of entry into a business or onto

a new beam and also carry real estate,

expertise and manpower costs

• Remote antenna size determines

overall network spend along with

installation costs

• Satellite access radios

• Hub HPA costs requires significant

spend and must be used efficiently

• ODUs in the field are the main hardware

cost element, both in terms of

equipment, installation and power draw

(generator, solar panel, etc.)

Space Segment

• Existing satellite platforms and modems have been designed to support different applications and topologies

• Point-to-Point �� Modems

• Point-to-Multipoint �� Platforms

• Each vendor’s platform allows for different modularity's as networks grow

• Modems can be added one

by one as needed

• Platforms differ in their scalability

with different commercial elements

• Advancements in Modulation & FEC have enabled:

• Reduced antenna(s) size(s)

• Reduced ODU size

• More efficient use of given kits

Scenario 1 – Double Throughput per Site

• Take advantage of power efficiency gains of Intelsat EpicNG Spot Beams to achieve higher throughput with existing remote kit

• Alternative is to visit each site to upgrade BUC to support increased throughput per site

Purchase of upgraded BUC

Scenario 2 – Network Expansion

• Increase size of addressable market by decreasing the total cost per site leveraging efficiencies of Intelsat EpicNG design

• Required kit size often a deterrent in growing network to reach new subscribers

• Ability of smaller kit to support a given traffic mix

Scenario 3 – Transition from C-band to Ku-band

• Take advantage of power efficiency gains of Intelsat EpicNG to achieve higher

availability with Ku-band

– Increase availability from typical 99.5% to 99.9% using extra margin in link

• Significantly decrease the cost per site to support a given throughput

Intelsat EpicNG Enabling New Possibilities Example 1: Simplify Operations & Reduce Total Cost of Ownership

Present mode of operation

• 400 MHz on 6 satellites

• 520 Mpbs total throughput• 6 uplink chains and 3 facilities• Complex operations• High TCO• Not easily scalable

Current Satellites Intelsat EpicNG

Future mode of operation

• 400 MHz on 2 satellites

• 1080 Mbps throughput (108% improvement)• Two uplink chains from 1 facility• Simple operations• Lower TCO• Scalable
