Calculate The Speed Of Cable Internet 

To calculate the speed of cable internet you can take help from several speed-check websites that offer one-click connection speed assessments for free, like Fat.com and Ookla Speedtest. Both are web-based services that can measure your connection’s latency, download speeds, and upload speeds from a remote server. Some ISPs have their own speed-chek pages as well, like Xfinity and AT&T. 

Your test will reveal a result in seconds, but make sure beforehand that no one on the network is downloading large files, streaming, video conferencing, gaming, or the like. You will want to know what your network is doing on an average day during a lull so you don’t skew your results. Then comparing your tested speed to the week will show many different speeds, so consider cross-checking and taking an average. 

About Cable Internet 

Cable internet is a type of broadband internet access that uses the infrastructure of cable Tv networks to provide internet services. It provides connectivity from the internet service provider to the end users in a similar manner as a digital subscriber line and fiber-to-the-home. Broadband cable internet access has a cable modem termination system as a cable operator facility, called a headend. The headend is connected to switching centers by a high-bandwidth fiber trunk. 

In cable internet, each switching center is connected to one or more fiber nodes through fiber optic cables. The local coaxial cable connects to the customer which has a cable modem to receive the services.
