3 What is Broadband Satellite? Broadband Satellite technology uses a RF satellite link to provide subscribers with broadband Internet access Similar to the technology used in DirecttotheHome (DTH) video broadcast (DirecTV, Dish Network); can coexist Targets users in a location with poor or nonexistent terrestrial infrastructure Early oneway systems capable of up to 400 kbps download, but used 56 kbps analog modem for upload New twoway systems expected to perform at 1 Mbps download and 500 kbps upload typically Satellite Access 3

4 Benefits & Applications Benefits Highspeed, alwayson Internet connection Access for users in areas with nonexistent or poor terrestrial infrastructure Integrated with Directtothehome TV equipment Works well for broadcastoriented data traffic Applications High speed Internet access Multimedia, elearning, gaming Video on Demand VPN VoIP Satellite Access 4

6 Drivers & Challenges Drivers Demand for highspeed internet in areas with poor or nonexistent terrestrial infrastructure Decreasing component costs Standardization for increased vendor interoperability Challenges Decreasing cost for equipment twoway terminals Latency needs to be improved Increasing capacity to mitigate shared bandwidth architecture Line of sight issues Satellite Access 6

7 Revenue Growth & Players Worldwide broadband satellite equipment market forecasted to grow from $300M in 2000 to $1.6B in 2007* Main Service and Equipment providers Hughes Electronics: DirecWay service Formerly DirecPC; provider of DirecTV Echostar Technologies: Starband service Provider of Dish Network * Pioneer Consulting Satellite Access 7

8 Technology & Equipment

9 Oneway Architecture Download Internet Satellite Access Service Provider Hub Station PSTN Upload Home User Home users dialup connection to upload data to the service provider s Hub station which forwards the request to the internet Requested data is broadcast back to home users via satellite Have fast download, but slow upload Sufficient for normal web surfing, downloading, video/audio streaming Satellite Access 9

10 Twoway Architecture Download Internet Satellite Access Service Provider Upload Home User Satellite transmission in both Download and Upload channels Download is a broadcast protocol and Upload is TDMAbased Much faster upload speeds compared to oneway architecture Good for applications like video conferencing (highbandwidth, twoway communication) Satellite Access 10

11 Standards Proprietary standards DSS: Hughes Network Systems (HNS) proprietary Open standard DVB consortium standard: DVB (ETS ) Recently proposed DVB Return Channel over Satellite (DVB RCS) as the standard for the return channel on newer twoway systems Satellite Access 11

12 Satellite Access Equipment Subscriber Side Ground Terminal Outdoor Unit (ODU) A small (~23 ft diameter), lowcost dish antenna with transmit and receive components placed at the focal point of the antenna Receives/sends data from/to the satellite in twoway systems Oneway systems use a dish for download direction only Needs to face the southern sky for proper transmission Indoor Unit (IDU) A Satellite Modem which serves as an interface between the ODU and customer equipment and controls satellite transmission Analog Modems are used in one way systems to upload subscriber data to the ISP via the PSTN Satellite Access 12

13 Satellite Access Equipment Service Provider Ground Station (Hub) Outdoor Unit Dish antenna (1536 feet) and transmit/receive operate similarly to subscriber terminals Indoor Unit (Access Server/Gateway) The equipment which demodulates an incoming signal from the ODU carrying IP packets and sends the packets to local network Traffic could be transported to the Internet, over a VoIP gateway to the PSTN, to a local cache, from a streaming server, etc. Network Management System (NMS) is the portion of the satellite server that manages the activity at the Hub Satellite Access 13

14 Satellite Access Equipment Spacecraft Highpower, Geostationary Earth Orbit (GEO) satellite located at 23,800 mi. above the equator and operating typically in the Kuband (1114 Ghz) and/or Kaband (2030 Ghz) Satellite Access 14
