  1. New Opportunities through New TechnologiesWireless and Satellite Communications Jack Rigley Vice President Satellite Communications Research Communications Research Centre Aug 25, 2000

  2. Outline • Types of Digital Communications Systems • how do you connect to the information highway? • Why Wireless? • Brief overview of Terrestrial Wireless and Satellite broadband communications • Why this is important.

  3. Canada - One Perspective

  4. “Making Canada the most connected nation in the world”

  5. 16000 schools connected to the Internet - March 1999 10% by satellite

  6. Digital Communications Systems • Plain Old Telephone System (POTS) - 56kbps • Cable Modem - 4 Mbps • Digital Subscriber Line (DSL)- 8 Mbps • Wireless 10 - 100Mbps $10/user • Fibre Optics - 1 Gbps $1,000/user

  7. Wired Systems

  8. Two Types of Wireless • Terrestrial Wireless • Satellite Communications

  9. Terrestrial Wireless

  10. Why Terrestrial Wireless? • Alternative to fibre and copper wire • New technology: deliver today’s services and meet tomorrow’s demands • Low start-up costs: need to install base stations only, “pay as you go”, viable for low penetration rates

  11. What is LMCS/LMDS?Local Multipoint Communication System/Local Multipoint Distribution System an access technology for the delivery of the following services: • voice/telephone • data • internet access • high speed broadband access • video broadcast

  12. antenna service area

  13. Satellite Communications

  14. Arthur C. Clarke, 1945 • Geostationary Earth Orbit • 36,000 km Ubiquitous Coverage - same level of service Rapid deployment - instant infrastructure Affordability

  15. Anik F2 Remote Communities Schools Telecommuters Hospitals Business Internet & Broadband Networks Gateways

  16. An Example October 1996: Children at the Milton J Rubenstein Museum of Science and technology (MOST) in Syracuse NY participated in a live tour of Ottawa’s Aviation Museum via broadband satellite communications link

  17. Near Future • Terrestrial broadband systems licensed and starting to roll out around the world. • Broadband Multimedia Satellite systems beginning services this year with many more to be launched the next 5 years, providing global broadband access.

  18. Get Ready
