If you think coaxial cable only exists to provide low-quality daytime TV channels and sports that you would never request, then you're not alone.
Most people don't realize that the same cable silently installed in their walls can also provide a fast and stable internet connection . Even fewer realize that many of us are using it for our entire digital lives.
But that's entirely possible, and many people should even consider it if they have a stable 100/50 Mbps connection at home and have never experienced any connection problems.
What exactly is Internet over coaxial cable?
Fiber optic cable isn't necessarily the only way to get fast speeds.
Internet over coaxial cable uses the same type of physical cable used for cable television, if you don't want to stream online at home. Remember that thick, round, and rigid cable? Inside that cable is a copper core surrounded by a shielding layer, capable of transmitting high-frequency signals very well without turning them into interference.
Instead of just transmitting television signals one-way, internet service providers use a standard called DOCSIS to send data both down to you and back up to the network. That means email, video calls, cloud syncing, streaming, backups, and of course, countless browser tabs. The internet arrives as radio signals inside coaxial cable. The cable modem listens, decodes, responds, and forwards the data to the router. From there, it works just like any other home network. Nothing magical; just old technology that's been very well optimized doing new tricks.
Your internet doesn't run via coaxial cable the entire way across the country, as that would be a nightmare. Instead, providers use a hybrid fiber-coaxial network, where fiber optic cables transmit data at extremely high speeds from the provider's core network to a network node in the neighborhood. From that node, coaxial cable handles the final leg into the house.
That final section is where most people connect. Therefore, fiber optic connections are used for long-distance transmissions, while coaxial cables are used for local distribution. Furthermore, coaxial cable is an efficient, proven technology installed in millions of buildings – you might even be using it in your home without knowing it.
Why is coaxial cable faster for downloading than uploading?
Don't forget about connection stability!
The original cable network was built for one-way traffic. Television went down to you, and nothing went up the cable. The internet changed that, but the infrastructure still prioritizes downloads. That's why many coaxial cable packages still offer much faster download speeds than upload speeds.
For most households, that's perfectly fine. Most people download more than they upload through streaming, web browsing, updates, cloud app access, etc. All of these activities rely heavily on download speeds, with minimal requirements for upload speeds. However, coaxial cable may not be the best option if you upload large files, play online games, need frequent cloud synchronization, and similar activities.
However, many people use coaxial internet for their "normal" digital lives and rarely experience any speed issues, as it suits their daily needs. Another feature of coaxial internet that many people really appreciate is the stability of the connection, which is extremely important for those working from home.
Why do many people use coaxial cable at home and won't change it anytime soon?
Who is coaxial internet really for?
Most people have several different internet connection options to choose from. However, that's not true for everyone. But if you have coaxial cable available at home, considering using it is a worthwhile option for a few reasons:
- Availability : The cable is already in your home, so why not give it a try?
- Speed : Internet over coaxial cable typically provides speeds fast enough for working, creating, streaming, syncing, and testing without worrying about connectivity.
- Stability : Many people would rather have a stable, reliable internet connection than theoretical perfection that hasn't yet been installed in their building.
Therefore, coaxial cable is particularly useful if:
- You do not have fiber optic access.
- You want fast downloads without paying high fees.
- You value stability over ostentation.
- You work from home and need consistent performance.
- You don't upload terabytes every day.
The problem is, coaxial cable isn't new or flashy, so people don't think about it. But it's still working quietly in the background, and that's something that's really appreciated.
