Question

What is the maximum bandwidth limitation of coax technology?

Answer 1

So a Coaxial cable for any internet service an be ran at best 50 Mbps Digital Signal 3 carriers, But depending on Carrier and application i've seen modems run up to like 50 and higher Mbps through ISP but our computers are only designed to run 10 or less Mbps depending on your motherboard. I hope this is what you were asking. If not than idk bro

Answer 2

The rate of impedance or to be clear, resistance at a certain level of frequency is what determines the rating of the coax cables.

So it varies with the type of coax that you do use.

It is the capacity of the coax cable which provides the proper bandwidth frequency.
