What is DOCSIS 3.1?
DOCSIS 3.1 is the newest and fastest cable modem standard available today. It is the upgrade from the previous DOCSIS 3.0 standard that most cable modems use currently.
DOCSIS stands for Data Over Cable Service Interface Specification. It is the technology that allows broadband internet to be delivered over a cable TV network.
The main benefits of DOCSIS 3.1 over 3.0 are:
- Faster speeds – DOCSIS 3.1 modems can achieve speeds up to 10 Gbps down and 1 Gbps up. DOCSIS 3.0 maxes out at 1 Gbps down and 200 Mbps up.
- Lower latency – The time it takes for data to travel back and forth is reduced with 3.1. This results in less lag for online gaming and video calls.
- More bandwidth – DOCSIS 3.1 is more efficient with bandwidth, allowing your whole home to use more devices online simultaneously.
When Does it Make Sense to Upgrade?
Upgrading to a DOCSIS 3.1 modem only makes sense if your cable internet provider offers DOCSIS 3.1 service.
Check if DOCSIS 3.1 is Available
The first step is to contact your cable provider and ask if they have deployed DOCSIS 3.1 in your area yet. The major cable companies like Comcast Xfinity, Spectrum, Cox, and Mediacom have been slowly rolling out DOCSIS 3.1 service to select markets over the past couple years.
You can also check their website or online availability checker to see if DOCSIS 3.1 internet plans are offered at your address.
Get a Modem That Supports DOCSIS 3.1
If DOCSIS 3.1 is available, you’ll need a compatible modem to take advantage of the faster speeds. Your existing DOCSIS 3.0 modem will not work.
The most popular DOCSIS 3.1 modems are:
- Arris SB8200
- Motorola MB8600
- Netgear CM1000
- Asus CM-1000
These are available from most electronics and cable provider stores for $150-$200.
Choose a Plan With Enhanced Speeds
Finally, you’ll need to upgrade your internet plan to a DOCSIS 3.1 tier to achieve gigabit speeds. For example, Comcast’s Gigabit and Gigabit Pro plans can only be accessed with a 3.1 modem.
If you switch modems but keep the same lower-tier plan, you won’t see any speed improvements.
The Benefits of Faster Speeds
The main benefit of upgrading to DOCSIS 3.1 is being able to access gigabit internet speeds, which unlocks new possibilities for your home network.
Here are some examples of how a gigabit DOCSIS 3.1 connection can be utilized:
-
4K/8K video streaming – Ultra HD streaming services like Netflix, YouTube and Amazon Prime Video require 25+ Mbps for smooth playback. A gigabit connection ensures you can stream 4K/8K on multiple devices simultaneously.
-
Smart home technology – With more smart devices like security cameras, video doorbells, smart appliances and voice assistants becoming prevalent, faster speeds provide the necessary bandwidth for these latency-sensitive gadgets.
-
Online gaming – Multiplayer gaming and real-time game streaming demands low latency and a robust connection. DOCSIS 3.1 provides a lag-free gaming experience.
-
Faster downloads – Large files, system updates, and cloud backups will download in seconds instead of minutes with a gigabit modem.
-
Eliminate buffering – Slow buffering when streaming or downloading content can be infuriating. DOCSIS 3.1 provides consistently fast speeds to eliminate this bottleneck.
-
Improved video calls – Video conferencing services like FaceTime, Skype, and Zoom require steady, low-latency connections for smooth video and no dropouts.
Is it Worth Paying More for Faster Speeds?
While the benefits of gigabit speeds are enticing, DOCSIS 3.1 service usually comes at a higher monthly cost than standard internet packages. You’ll have to decide if paying more is worthwhile for your household needs.
Here are some factors to consider:
- How many people/devices are using your home network simultaneously? More users means more bandwidth needed.
- Do you have bandwidth-heavy uses like 4K streaming, smart home tech, online gaming, etc.?
- Do you frequently get frustrated with slow speeds or buffering when streaming/downloading?
- Are you willing to pay an extra $20-$50/month for faster service?
- How long do you plan to stay at your current residence? Upgrading may not be worthwhile if moving soon.
For many households with lots of connected devices and streaming media, gigabit speeds provide a noticeable improvement in home network performance.
Conclusion
Upgrading to a DOCSIS 3.1 modem and internet plan is recommended if you want to unlock the next level of broadband speeds up to 1 Gbps. Take the time to check availability with your cable provider and weigh the benefits versus costs to decide if it’s worthwhile for your home.
