DOCSIS 3.1 Modem vs 3.0 Speeds and Testing

Learn > Cable Modem & Routers > DOCSIS 3.1 Modem vs 3.0 Speeds and Testing

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard for the addition of high-bandwidth data transfer to an existing coaxial cable TV system. The DOCSIS standard influences which modem you get for a cable Internet connection. There are two standards widely used on the market today: DOCSIS 3.0 and DOCSIS 3.1.

The latest DOCSIS standard, DOCSIS 3.1, is ​capable of 10 gigabits per second (Gbps) download speeds and 1 Gbps upload speeds. However, the most widespread DOCSIS standard is DOCSIS 3.0, which is capable of 32 download channels at one time and over 1 Gbps download speeds.


Future-proof your Internet connection for faster speeds and lower latency.

Gigabit Internet speeds on your existing Cable connection

Get a huge jump in download and upload Internet speeds delivering up to 10 Gbps download and 1 Gbps upload speeds.

Enhanced gaming, streaming and VoIP calls

Advanced packet queueing reduces latency and minimizes lag, improving online gaming, streaming and voice quality.

Backward-compatible for worry-free upgrades

When you upgrade to a DOCSIS 3.1 modem your device will still work on your ISP’s existing network and is ready for when higher speeds are rolled out in your service area.

Higher Speeds and more data to more devices

Higher capacity for upstream and downstream data transfers means the technology can deliver more speed and data wherever you need it.

What is DOCSIS 3.1 speed testing?

Speed testing is when your ISP technician tests your network speeds to make sure you are receiving the speeds you subscribe to. When running these tests, technicians can identify if there are any issues and troubleshoot them right away while on the premise. This saves both you and your ISP a lot of time and money since they are already on site, instead of having to send someone back out to fix any issues that could have been discovered at the point of installation.
