DOCSIS 4.0 Is the Next Generation of Cable Modem Technology
DOCSIS 4.0 represents a major leap in cable broadband performance. If you’re researching what it means for your home Internet setup—or considering when to upgrade—this guide covers everything you need to know, from benefits and capabilities to key differences compared to DOCSIS 3.1.
As Internet demands grow with 4K streaming, remote work, and cloud gaming, the need for faster upload speeds and lower latency is rising. DOCSIS 4.0 addresses those needs—and prepares your home network for the future.
What Is a DOCSIS 4.0 Cable Modem?
A DOCSIS 4.0 cable modem is a device that connects your home to the Internet through your cable provider, using the latest DOCSIS (Data Over Cable Service Interface Specification) 4.0 standard. Compared to DOCSIS 3.1, this new standard delivers multi-gigabit upload and download speeds, reduced latency, and enhanced energy efficiency.
DOCSIS 4.0 builds on existing coaxial infrastructure, making it a practical upgrade path for cable providers and consumers alike.
Key Benefits of DOCSIS 4.0
DOCSIS 4.0 isn’t just faster—it’s smarter and more capable. Here’s what makes it stand out:
- Symmetrical Multi-Gigabit Speeds: Up to 10 Gbps downloads and 6 Gbps uploads.
- Better Support for Upstream-Heavy Applications: Ideal for video conferencing, live streaming, and cloud backups.
- Lower Latency: Improves online gaming, remote desktops, and real-time applications.
- Future-Proof Technology: Ready for emerging home and business needs over the next decade.
DOCSIS 4.0 vs DOCSIS 3.1: What’s the Difference?
Feature
DOCSIS 3.1
DOCSIS 4.0
While DOCSIS 3.1 modems (like Hitron’s CODA and CODA56) still meet most home needs, DOCSIS 4.0 adds more capacity for upstream-intensive activities—an increasingly important advantage.
Who Should Consider a DOCSIS 4.0 Modem?
DOCSIS 4.0 will appeal to:
- Early Adopters and Tech Enthusiasts
If you consistently upgrade to the latest gear or push your network to its limits. - Remote Workers and Small Business Owners
Who need consistent upload bandwidth for video meetings, VPN, or file syncing. - Content Creators and Gamers
Who livestream, upload large files, or play latency-sensitive games. - Future-Planners
Anyone upgrading their modem and wanting long-term performance and compatibility.
When Will DOCSIS 4.0 Modems Be Available?
DOCSIS 4.0 modems are beginning to roll out gradually as ISPs complete upstream network upgrades to support the new standard. Most deployments in North America are expected to ramp up over the next 12–24 months.
To check if your ISP supports DOCSIS 4.0 or plans to soon, visit their equipment compatibility page or contact customer support.
What to Know Before Upgrading
Before purchasing a DOCSIS 4.0 modem:
- Confirm ISP Support: Your cable provider must support DOCSIS 4.0 in your area.
- Watch for Certifications: Look for CableLabs certification and ISP approval.
- Evaluate Your Plan: Ensure your Internet plan actually uses the higher speeds.
- Check for Compatibility: New DOCSIS 4.0 modems will still support DOCSIS 3.1, but you’ll only benefit from the upgrade when your ISP enables it.

FAQs
What does DOCSIS stand for?
DOCSIS stands for Data Over Cable Service Interface Specification. It’s the standard that enables high-speed data transmission over cable TV systems.
Can I use a DOCSIS 4.0 modem with a DOCSIS 3.1 Internet plan?
Yes. DOCSIS 4.0 modems are backward compatible with DOCSIS 3.1 networks, but you’ll only benefit from DOCSIS 4.0 speeds if your ISP supports it.
Will DOCSIS 4.0 improve my Wi-Fi?
DOCSIS 4.0 improves the speed and efficiency of your Internet connection from your cable provider—delivering up to 10 Gbps download and 6 Gbps upload speeds to your modem. While it doesn’t directly enhance your Wi-Fi, these faster wired speeds can boost overall performance when passed through a high-quality router or mesh Wi-Fi system. To experience the full benefit, you’ll still need a router capable of handling multi-gigabit speeds.
Is DOCSIS 4.0 available in my area?
Availability depends on your ISP. Many cable providers are in the process of upgrading to DOCSIS 4.0, so check with your provider for rollout timelines.
Do I need a DOCSIS 4.0 modem right now?
If your current DOCSIS 3.1 modem is working well and your ISP hasn’t launched DOCSIS 4.0 yet, you may want to wait until it’s officially supported in your area.
Are DOCSIS 4.0 modems available to purchase today?
As of now, DOCSIS 4.0 modems are not widely available at retail. Most are being tested or deployed in limited quantities through Internet providers. Wider availability is expected as ISPs complete their network upgrades.
Looking for high-performance, ISP-approved cable modems you can rely on today?
Check out Hitron’s CODA (1 Gbps Ethernet) and CODA56 (2.5 Gbps Ethernet). Both are DOCSIS 3.1 modems designed for speed, reliability, and compatibility with major North American ISPs.
