It’s easy to overlook many important features when you’re shopping for an appropriate modem for your cable connection. Sellers take advantage of your ignorance and don’t explain what you’re paying for. Namely, the things that you want to be mindful of when you’re buying a cable modem are:
The “Data Over Cable Service Interface Specification”, or DOCSIS, is the protocol that allows your service provider to establish a broadband connection. Its first version introduced the possibility of transferring data over a cable television system. Over time, this technology has improved substantially.
The modem’s DOCSIS version will determine its downstream and upstream capacities, among other features. Choosing a modem with an older DOCSIS protocol will limit your connection speed if the modem can’t support it. Besides, getting a good DOCSIS 4.0 cable modem will ensure that your modem won’t become obsolete any time soon .
Your download speed indicates the amount of time it takes for data to be delivered to your device. It’s usually measured in megabits per second (Mbps), and its crucial to the user’s online experience. Having a modem with a low download speed means longer loading times.
Remember to buy a modem that matches, or surpasses, your connection speed. If you don’t, you won’t be able to fully enjoy your connection speed until you do. You can’t have a 1Gbps connection with a 40Mbps modem and expect it to work somehow. However, using a DOCSIS 4.0 cable modem you shouldn’t have any issues even with a 10Gbps internet service.
Traditionally, upload speeds have been considerably lower than download speeds. That’s because, when you’re online, you usually request for more data than you send. Your upload speed measures the amount of time it takes for your connection to do the latter. Nonetheless, as new ways to interact with the internet emerge, like virtual reality, the need for higher upload speeds grows.
CableLabs has been working on a solution to that problem. DOCSIS 4.0 cable modems are capable of unprecedented upload speeds. When new technologies arrive, most people are going to migrate to DOCSIS 4.0 eventually.
Cable modems are supposed to be used with a compatible service provider. Otherwise, they’ll malfunction or, likely, won’t work at all. It could mean that you have to purchase a new modem if you change your provider. Or you spend a bit more and get a modem with better compatibility from the start.
Most cable modems have rather limited compatibility. They usually only work with a couple of service providers. Getting one with high compatibility allows you to change service providers without the need to acquire a new modem. It’s a great way to ensure that you are free to switch service providers without minding about the extra expense.
Every time a new milestone is reached, both consumers and providers start migrating to the newer standards. Once everything is settled, developers catch on and take advantage of the better connection speeds. They provide a richer user experience and you get to enjoy it if you’re able to keep up.
DOCSIS 3.0 was the standard protocol for more than a few years. It changed the way we use our electronic devices in many ways. But now, with service providers offering connections up to several gigabits per second, things are changing again. To get a 10Gbps connection, a new protocol was devised. DOCSIS 3.1 came along to allow such speeds.
CableLabs has been working with the industry to improve on the 3.1 version of its protocol. These efforts paid off in the form of DOCSIS 4.0’s superior performance over the previous version. It’s the next step to take before making 10Gbps connections to the new standard.
The third version of the DOCSIS protocol was a major game-changer back in the day. Before that, download speeds were limited to 40Mbps, and most modems allowed for only a fraction of that speed. As new ways to stream and consume content online emerged, a new update in the DOCSIS protocol was necessary.
Later on, as the development of more bandwidth-demanding applications became common, connections needed a new update. Improving on their 3.0 version, CableLabs managed to make 10Gbps connections a reality. Along with other improvements, like its Full Duplex capacity, DOCSIS 3.1 is superior or equal to the previous version in every way.
Further development over the 3.1 protocol gave birth to DOCSIS 4.0. Working with the same fiber cable as its predecessors, DOCSIS 4.0 offers a significant improvement in upload speeds. Managing the upstream and downstream processes efficiently, it managed to provide upload speeds up to 6Gbps.
As time moves forward, it’s likely that this will become the new standard for internet connections. Video conferencing, online gaming and many other things will benefit greatly when it happens. Symmetrical streaming also offers a lot of opportunities for developers. Buying a DOCSIS 4.0 cable modem today is a step in that direction.
Picking the very best modem for your connection takes a bit of effort. To help you, we tested all the cable modems we could find to give you a list of the best ones. Although results usually vary depending on the service provider, these modems delivered consistent performance with supported connections.
After thoughtful evaluation, the best cable modems available in the market, in our opinion, were:
