Coaxial cable internet, or coax internet, delivers best effort broadband service through the same coaxial cables used for cable television. These cables consist of a copper core surrounded by layers of insulation and shielding, enabling them to carry large amounts of data over long distances.

Coax internet typically offers faster download speeds compared to upload speeds, making it suitable for residential general browsing, streaming, and downloading. However, because it is a shared medium, the performance can vary depending on the number of users on the network.
