What’s DOCSIS 3.1?

Earth growing faster with the touch of speedy technology which can offer the fastest route of anything within a sort of time. Similarly, cable operators found a new way to provide blazing speed without the need to replace millions of miles of existing wiring.

We are talking about DOCSIS 3.1 which has created mythical opportunities for cable operators to deliver gigabyte speed without the need for a traditional fiber network.

In fact, speeds with DOCSIS 3.1 standard could ultimately reach up to 10Gps which is over 10 times faster than the older version of DOCSIS (3.0). Now the question is, how does it work?

Cable providers have used multiple frequency bands to allow simultaneous transmission of several signals through the same coaxial cable until they found this technology. Modulation techniques allow these signals to transmit data from the Internet to your home which was quite slow and unable to carry sufficient data at once.

You can think of it like lanes on a highway where you have space between lanes to avoid interference or collisions.

But with DOCSIS 3.1 new modulation techniques allow for even more bits of data to be packed in each transmission. DOCSIS 3.1 improves the transmission methods so even more signals can be transmitted along the same cable.  

You can enjoy the fastest Internet downloads, streaming, gaming, & surfing speeds possible to all of the devices in your home while using your cable networks. Comcast has already started rolling out its gigabit XFINITY Internet service using DOCSIS 3.1.
