Why 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

An ExampleAn ExampleOctober 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 FutureNear 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.
