New Opportunities through New Technologies Wireless and Satellite Communications Jack Rigley Vice President Satellite Communications Research Communications Research Centre Aug 25, 2000

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.

Canada - One Perspective Canada - One Perspective

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

16000 schools connected to the Internet - March % by satellite

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

Wired Systems

Two Types of Wireless Terrestrial Wireless Satellite Communications

Terrestrial Wireless

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

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

antenna service area

Satellite Communications

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

Internet & Broadband Networks Remote Communities Schools Business HospitalsTelecommuters Gateways Anik F2

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

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.
