Cable Internet #
- In the case of cable Internet, the TV cable company is the ISP and it relies on the preexisting infrastructure of cable TV to grant Internet access.
- It runs on coaxial cable. Coaxial cable has enough of a frequency range to carry TV channels and a stream of upstream and downstream Internet.
How It Works #
- In essence, cable Internet works very similarly to DSL.
- A device on both the user’s end and the ISP’s end modulates the analog signals to digital and vice versa.
