What Is CAT 6A Cable and Why Does It Matter for Your Home or Office Network?
If you've ever dealt with slow internet, spotty WiFi, or a home network that can't keep up with everyone streaming, gaming, and video calling at the same time, the problem might not be your internet plan or your router. It might be the cable running through your walls. Most homes and many small offices in the Towson and Baltimore County area are still wired with older Ethernet cable, if they're wired at all. Upgrading to CAT 6A cabling is one of the most impactful infrastructure improvements you can make, and it's something most people don't know to ask about.
We put together a video showing a CAT 6A installation from start to finish so you can see what the process actually looks like. You can watch it above. Below, we'll explain what CAT 6A is, how it compares to older cable types, and when it makes sense to upgrade.
What Is CAT 6A?
CAT 6A (Category 6 Augmented) is a type of Ethernet cable designed to support network speeds up to 10 Gbps (gigabits per second) over distances up to 100 meters. It's a significant step up from CAT 5e, which tops out at 1 Gbps and is the cable that's still installed in the majority of homes and older office buildings. CAT 6A also has better shielding against crosstalk and electromagnetic interference, which means more consistent, reliable performance, especially over longer cable runs or in environments
with a lot of electrical interference.
How Does It Compare to Other Cable Types?
CAT 5e supports up to 1 Gbps and has been the standard in residential and small commercial installations for years. It still works fine for basic internet use, but it's increasingly the bottleneck in homes with fast internet plans, multiple users, and bandwidth-heavy devices.
CAT 6 supports up to 10 Gbps but only over short distances (up to about 55 meters). For longer runs, it drops back to 1 Gbps. It's better than CAT 5e but doesn't give you the full benefit over longer distances.
CAT 6A supports 10 Gbps at the full 100-meter distance with better shielding and interference resistance. It's thicker and slightly more expensive than CAT 6, but it's the standard we recommend for any new installation because it future-proofs your network. Internet speeds are only going up, and the cable in your walls is going to be there for a long time. Installing CAT 6A now means you won't need to re-run cable when your internet plan catches up to what the cable can handle.
When Does a CAT 6A Upgrade Make Sense?
Not every situation calls for a full cabling upgrade, but there are some clear signs that it's time to consider one. If you've upgraded to a high-speed internet plan (500 Mbps or higher) and aren't seeing those speeds at your devices, old cabling could be the reason. If you work from home and need a reliable, fast connection for video calls, large file transfers, or VPN access, hardwired connections over quality cable will always outperform WiFi. If you're building a new home, renovating, or setting up a new office space, running CAT 6A during construction is dramatically cheaper and easier than
doing it after the drywall is up.
For small businesses, the case is even stronger. If you have multiple workstations, a NAS or local server, security cameras, or VoIP phones, all of those devices perform better on a wired connection, and CAT 6A gives you the headroom to grow without hitting a ceiling.
Why Professional Installation Matters
Ethernet cable installation isn't just about pulling wire from point A to point B. The cable needs to be routed properly to avoid interference from electrical wiring, HVAC systems, and other sources of noise. Terminations need to be done correctly or you'll get intermittent connections, slow speeds, or complete drops. Cable runs need to be tested to verify they're actually performing at spec. And the physical routing needs to be clean and protected so the cable lasts for years without issues. We've seen plenty of DIY and handyman cable runs that were technically connected but performing well below what the cable was capable of because of a bad termination, a cable that was kinked behind a wall, or a run that was routed right alongside electrical wiring. Getting it done right the first time saves money and frustration in the long run.
How We Help
We design and install CAT 6A cabling for homes and small businesses throughout Towson, Timonium, Cockeysville, Owings Mills, and all of Baltimore County. Whether you need a single cable run from your router to a home office, a full-home wiring job with drops in every room, or a structured cabling setup for a small business with multiple workstations and access points, we handle everything from planning the layout to terminating and testing every run.
If your network isn't performing the way it should, or you're planning a project that involves new cabling, give us a call or text at (443) 943-4440. We'll take a look at what you have, talk through what would make the biggest difference, and give you a clear picture of what's involved before any work starts.
