Kaapelimodem

Kaapelimodem is a type of modem that uses a cable television infrastructure to provide internet access. It utilizes radio frequency signals that travel over the coaxial cable lines used for cable TV. This technology allows for high-speed data transmission, often significantly faster than traditional dial-up or DSL connections in many areas.

To connect to the internet via a cable modem, a user needs a cable line installed and active service from an internet service provider that offers cable internet. The cable modem itself is a device that translates the digital signals from a computer into a format that can be transmitted over the cable network, and vice-versa. It typically connects to a computer or a router via an Ethernet cable.

Cable modems are a popular choice for home and business internet due to their speed and reliability. The bandwidth is shared among users in a particular neighborhood, which can sometimes lead to slower speeds during peak usage times. However, advancements in cable technology, such as DOCSIS (Data Over Cable Service Interface Specification), have continuously improved performance and capacity. Many modern cable modems also incorporate Wi-Fi capabilities, acting as a wireless router as well as a modem.
