Hence, a telecommunications operator that wants to compete with, say, a cable com- pany, must make the necessary infrastructure upgrades to provide broadband services.
On the supply side, neither the terminal equipment nor the transmission infrastructures are still well prepared to provide broadband video and switched data service (Owen, 1999).
In this section, we concentrate on the technological alternatives to provide broadband inter- activity to the homes.
Traditionally, the broadcasting of radio or television signals (wired or wireless) was in essence a broadband, one-way com- munication.
Because the use of the main lines - trunk technologies - is spread across a lot of users, they used to be broadband- coaxial cable, radio towers that transmit microwave sig- nals, communication satellites or fibre optic.
