Cable internet transmits data over coaxial cables using DOCSIS (Data Over Cable Service Interface Specification) technology. The latest standard, DOCSIS 3.1, supports speeds up to 10 Gbps downstream and 1 Gbps upstream. Data travels from your ISP's head-end facility through neighborhood nodes to your home's coaxial connection, where a cable modem converts the signal for your router. Because cable is a shared medium, speeds can fluctuate during peak usage times in your neighborhood.
