What is a satellite Why Satellite Communication Satellite vs terrestrial and others Choosing Communication Platform

2

Satelit is man made object launched into space orbiting the earth

Arthur Clarke’s vision of satellite , 120 degree apart, circling the earth as global communication medium (1945)

Relay in Space

First Russian satellite Sputnik 1 launched in 4 Oct 1957

• Communication satellite is a Relay in Space

First American satellite Explorer1 (31 Jan 1958)

A satellite communications system is an efficient way to link multiple communication sites together within a large area of coverage.

It consists of two segments :– Ground Segment (terminal, earth station)

Responsible for delivering user communications to the space segment

All satellite terminals within the coverage can communicate

– Space Segment ( satellite ) The communication satellite is a

microwave repeater in the sky Transponder receives signals at a

given frequency (uplink), amplifies it and retransmits them at corresponding frequency (downlink)

Indonesia is early adopter of satellite communication (Palapa A - 1976)

Indonesia has adopted an ‘Open Sky’ Policy since early years

Foreign satellite can serve Indonesian market – Landing Right requires Reciprocity– Coordinated satellite – No interference to other

Indonesian telecommunication systems6

Indonesian Satellites have enjoyed spectrum priority over terrestrial– Ext-C Band vs Broadband WiMAX– S-Band vs Broadband WiMAX and LTE

Satellite is viewed as Strategic for Indonesia’s archipelago– Broadband is better via fiber but takes time and

resources to link 13,997 island

Point to Point

Microwave Radio Trunking WiMAX WiFi Fiber Optic Wired (copper, coax) Satellite

Point to Multipoint

WiMAX Radio Trunking UMTS LTE WiFi Satellite

10Which one is best ?

Wireless vs wired

All wireless requires specrum allocation

Spectrum is limited resource

Time to deploy Life time of service Geographical terrain

– Indoor vs outdoor

Voice, Video or Data transmission

Satellite vs Fiber Optic

Satellite is best for broadcast/multicast / 1way

Wide coverage Expensive to launch

11

FO is getting cheaper to lay

Best for throughput Point to point only

12

WiMAX vs LTE

Similar technology but different in origins

Still requires spectrum Eccosystem is important Time to market

WiFi vs 3G

Licensed vs Unlicensed Indoor vs outdoor Widely available /

inexpensive Non QOS IEE802.11 to IEE802.22 CDMA, GSM & all 3GPP

are all voice derived technology

Super WiFi13

Regulation (license, standard , TKDN) Product availabillity (market mass scale) Innovation & new technology

– Hybrid Fiber + Coax or FTTH– Satellite + 3G– Pico Cell
