Thanks to new technology being introduced each day, it’s no surprise that we’re now entering a world with uber-fast gigabit internet. Even though the service is not yet being offered worldwide, it won’t take long until this lightning-fast internet service reaches your area. And when it arrives, it’s best to be prepared.
Unfortunately, current modem models cannot handle the awesome speeds of gigabit internet. You have to invest in a modem that runs on DOCSIS 3.1 for it to work properly.
So if you’ve been planning to upgrade your modem – or simply looking for a new one to prepare for gigabit internet – then look no further because you came to the right place. We reviewed seven of the best gigabit DOCSIS 3.1 modems in the market to help you find the perfect one for you.
In this article, you will learn:
What is DOCSIS 3.1?
Data Over Cable Services Interface Specification, often abbreviated as DOCSIS, is a widely-recognized standard involving the transfer of data with the use of cable systems.
With that said, DOCSIS 3.1 is the latest update for this technology. In a second, this modem can perform downstream transfers of up to a whopping 10 GB and perform upstream transfers of around 1 Gbps. And that’s truly impressive for cable network transfers.
Why Use DOCSIS 3.1 for Gigabit Internet?
But before we dive into the details, we want to answer some of the most common questions about DOCSIS 3.1 modems first. We’ll start with this: why use DOCSIS 3.1 for gigabit internet?
The answer to this question depends on the type of internet connection you have. If you’re using cable internet, the answer is yes. To support superior gigabit download speeds using cable internet, you need a DOCSIS 3.1 modem to make sure it works properly.
On the other hand, you do not need this type of modem if you’re using fiber internet connections. What you need for this type of connection is a fiber-optic modem.
