Broadband refers to a communication system which transports information across a single channel, such as cable, DSL, ISDN, and corporate LAN. Cable operators are transforming from entertainment companies into complete communication providers, since they are well suited to deliver high-speed Internet access and other Internet Protocol (IP) services to businesses and consumers. The demand for broadband connectivity in the home, for data and video transmission, continues to grow exponentially.
At the back-end of this market are the hubs/HFC networks connecting the subscriber’s premises to the headend/backbone infrastructure. The majority of the equipment in the broadband market is found within this headend which brings external services – satellite video, off-the-air video, Internet data, and voice – into the cable operator’s access network.
- Converged Cable Access Platforms (CCAPs) are systems that combine the edge QAM and CMTS functions into a single hardware package
- Wireless Routers are commonly used as wireless Internet access points in LAN/WLAN environments.
- Edge QAM – This hardware increases signal bandwidth by modulating the amplitudes of the carrier signals.
- Set-Top Boxes are electronic devices that are connected to a communication channel, such as a phone, ISDN or cable television line, and produces output on a conventional television screen.
- Transmission - A type of data transmission in which a single medium (wire) can carry several channels at once. Cable TV, for example, uses broadband transmission.
- Cable Modem Termination System (CMTS) is a system of devices located in the cable head-end that allows cable television operators to offer high-speed Internet access to home computers.
