A brand new cable system in an area that previously had no cable service is known as a new build. One very popular service that provides incremental revenue for cable operators is high-speed Internet access. This is done using cable modems, which are electronic devices that connect between the cable system and subscribers personal computers. A cable modem converts RF signals on the cable network to digital data and vice versa. The CMTS converts digital data from the Internet to RF signals that mays be carried on the cable network and vice versa.
Competition is the driving force behind many of cable s new services.
These small dish antennas are used to receive the satellite signals, which are transmitted in the 12 GHz frequency band. Digital video compression technology gives DBS providers the ability to transmit several hundred high-quality channels in the same spectrum normally occupied by a perhaps a few dozen conventional analog channels. As a result of DBS competition, cable operators have been deploying their own digital video and audio services. DSL is a technology used by telephone companies to transmit high-speed data over copper phone lines. DSL is a competitive threat we must take very seriously.
