  1. Broadband Internet Satellite ISOM 591 April 10, 2000

  2. High Speed Internet Access: Choices • Arun’s dilemma! • POTS (plain old telephone system) • ADSL • Cable modem • Wireless access device through PCS • new entrant - broadband satellite services

  3. Who’s in the Market Now • Hughes Network Systems (US) • www.hns.com • Europe Online • www.europeonline.com • Gilat-to-Home • Gilat Satellite Networks and Microsoft • www.gilat.com

  4. Current Services • DirectPC since 1996 (Hughes) • 100,000 subscribers • data rate rarely reaches the 400 kbps promised • traffic from the satellite is downstream only, phone line used for upstream traffic • new two-way services to be offered this year • hope to gain 1.2 million subscribers by 2003

  5. Technology • Current satellites use the C and Ku bands • Next generation • satellites will use the Ka-band • offers more spectrum • easier to find slots • digital on-board processing to better manage traffic • up to 226 Mbps

  6. Technology • Ka-band satellites built by Hughes’ Spaceway System, Astrolink, iSky, and NetSat28 • spot beam antennas focus the signal rather than dispersing signal and power across a large area • since energy is concentrated, the dish is smaller

  7. Data Transfer Rates • Current satellites - up to 400 Kbps • Cable - up to 1.5 Mbps • ADSL - up to 1.5 Mbps • Future satellites - up to 226 Mbps • looking for the business market • ability to charge users for the amount of band width consumer, like electricity is currently monitored

  8. Projects • Astrolink (Telespazio, a Telecom Italia company, Lockheed Martin, TRW, and Liberty Media) • www.astrolink.com • geostationary broadband that will initially use 4 of its 9 satellites • available in North America in 2003 • want to offer broadband at the same price as cable and DSL

  9. Projects • Gilat - founded in 1987 in Israel • low-cost satellite dishes and networks • merger with Spacenet (belonged to GE) • attempting to penetrate the US market over the last decade • iSKY - ww.isky.net • two way service over satellite, 1.5 Mbps, no phone line needed

  10. Projects • NetSat28 - www.netsat28.com • patented technology inside the satellite payload • 40 Gigabits of bandwidth out of one or two satellites, costing $250 million • want to deliver 30 - 40 Mbps at the same price as ADSL and cable

  11. Challenges • Pricing - can they live up to their promises? • Technology - expensive, proprietary • Funding and financing - investment costs will continue to increase • technical problems • launching problems _”lost in space” • maintenance • Is the market business or consumers?
