Is DOCSIS 3.1 required for Gigabit?

December 19, 2022

Yes, to take full advantage of Gigabit speeds with your cable Internet Service Provider (ISP), DOCSIS 3.1 is required.

What is DOCSIS anyway? Let’s get into it.

 

What is DOCSIS 3.1?

In plain language, DOCSIS is the technology that allows for high-bandwidth data transfer via existing coaxial cabling. DOCSIS stands for Data Over Cable Service Interface Specifications. It is globally recognized.

So, what does this mean? Well, when you’re looking for a cable modem, you want one with the highest DOCSIS technology. Today, that is DOCSIS 3.1, which is proven to be better than 3.0 in every way.

DOCSIS 3.1 cable modems allow for Gigabit speeds (Gbps) and have improved performance and bandwidth capability, including stronger security than DOCSIS 3.0 cable modems.

Some households may be able to get all their Internet needs met on DOCSIS 3.0, however DOCSIS 3.0 technology is considered end-of-life by the majority of ISPs.

 

Why do you want Gigabit speeds?

A cable modem that supports Gigabit Internet speeds increases your Internet bandwidth. This means better performance for online activities like:

  • Streaming 4K videos
  • Downloading large files
  • Video chatting
  • Livestreaming
  • Downloading games and updates
  • Online gaming
  • Streaming Netflix, Hulu, HBO Max, etc.
