A modem that converts signals sent on a coaxial cable that is also used for transmitting cable television signals. The modem box splits off the Internet signal from the TV signal to normally allow simultaneous operation. This would enable you to telecommunicate while watching a TV broadcast. One thousand Kbps appears to be a typical download speed, although faster speeds are technically possible. Cable modem users are primarily residential since many business areas are not wired for cable TV. Cable charges range $40–$60 monthly with modest installation fees.
