The "space" taken up by television signals traveling through cable is extremely small, leaving a large "bandwidth" for Internet traffic. A cable Internet account also frees up the use of your telephone line:

• hybrid fibre-optic/coaxial cable network - (LAN to your home)
• speed: upload/download (500 kb/sec - 1.5 mb/sec)
• $40-$55/mo fee, (the higher fee usually includes cable modem rental)
• includes ISP account and personal Web space (the cable company becomes your ISP)
• requires Ethernet card ($50-$100), which may be included in the rental fee
• requires basic cablevision service ($18/mo.)
• users must live in a Wave@Home-enabled area
• permanent connection, therefore, no time limit
