If you have it Internet for cableThen use the docsis technology. Docsis, which means Data on the Cable Service Interface SpecificationsIt is a standard that defines how your modem is broadcasting cable internet signals and from your home. If you have cable internet, either of Cape, Spectrum, Xfinity or one of the many Internet providers by regional cable ArmstrongUse a modem in accordance with docsis.
The DocSIS 4.0 cable modem is ideal as it produces faster load speeds. But although specifications for docsis 4.0 have been published, docsis 4.0 modems are not yet widely available for retail purchase. So this means that if you buy a new cable modem on the Internet, it is likely that it only has the choice of docsis 3.0 or 3.1. As the numbers suggest, the two versions of modem are similar, but we recommend opting for docsis 3.1 while waiting for a new 4.0 modem.
Modern cable modems comply with DOCSIS 3.0 or 3.1, with more and more Internet service providers recommended by DOCSIS Modems 3.1.
DOCSIS 3.0 vs. 3.1 vs. 4.0: What differences do you have?
Docsis is that standard cable modems use to move data.
Despite the simple tenth difference in versions, docsis 3.0 and 3.1 modems vary significantly in performance, price and availability. DOCSIS 4.0 would involve a greater leap of performance, but improvement has largely to do with upstream capacity. Here is a quick look at the advantages of each.
Advantages of Modem Docsis 3.0
- Price: Docsis 3.0 cable modems are generally cheaper than their counterparts 3.1.
- Availability: You are likely to have more options, including used or refurbished devices, when you buy a docsis 3.0 modem.
DOCSIS 3.1 Advantages of Modem
- Speed: DocSIS cable modems 3.1 support speeds faster than docsis 3.0 and thus adapt better High speed plansEspecially those with concert or higher speed speeds.
- Safety: Docsis 3.1 Modems can provide better online security than models 3.0, especially if you buy a combination device of modem-riot.
DOCSIS 4.0 ADVANTAGES OF MODEM
- Hang speeds: Docsis 4.0 is designed to “significantly increase the upstream capacity” according to KalelabsThe organization that establishes and tests the DOCSIS specifications.
- Future test: Docsis 3.1 is the current standard, but 3.0 is still used, almost two decades after its introduction in 2006. It is certain to assume that modems 4.0 will be useful for the next few years.
DOCSIS 3.0, 3.1 and 4.0 specifications
| Device | Maximum discharge speed | Maximum load speed | Price range | Specification issued |
|---|---|---|---|---|
| DOCSIS 3.0 | 1 Gbps | 100Mbps | 50 $ -150 $ | 2006 |
| DOCSIS 3.1 | 10 Gbps | 1 Gbps | $ 150 -250 $ | 2013 |
| DOCSIS 4.0 | 10 Gbps | 6 gbps | N/a | 2019 |

The purchasing suppliers on my address
The most significant difference between docsis 3.0 and 3.1 is that the latter can withstand download speeds 10 times faster than docs 3.0, up to 10 Gbps. Docsis 4.0 also admits downloads of up to 10 Gbps, but is able to significantly load up to 6 Gbps. Symmetrical, or closed speed capacity, download and load approves cable internet Fiber optics Internet Service.
DOCSIS 4.0 could open the way for faster cable plans with fastest load speeds
Most cable providers already offer a Gigabit plan with maximum speeds of about 940 or 1,000 megabits per second. AstoundCOX, XFinity and select other cable providers offer download speeds above 1,000MBPs. With DocSIS 4.0 technology, cable suppliers can offer even faster speeds through their current hybrid/fiber hybrid infrastructure.
The docsis 4.0 modem allows, especially Loading speeds much fasterWhich cable suppliers are very much. Loading speeds are more important than you think. Many north -American homes are seeing an upward trend in upward data or loading speeds. Certain activities such as using smart domestic devices And upload photos and videos on social networks, use your upward data. According to Cablelabs, Docsis 4.0 allows “an increase in upstream capacity and more options for operators to increase capabilities downstream.”
Still, Docsis 3.1 is the current standard for high -speed cable internet
If you choose speeds above 1 concert and rent your team, you will receive a MODEM-ROUTER Combo that includes docsis 3.1 integrated, so you do not have to worry about the specifications of your modem. Otherwise, if you decide to use your own team, you will want to spend a little more for a docsis 3.1 modem to make the most of the plan speed potential.
What if I do not need multi-gigabit concerts and speeds?
The speed potential of docsis 3.1 and 4.0 is impressive but unless you have High -speed planMaybe it doesn’t matter. Suppose your selected plan comes with speeds of up to 200MBPs. If you rent from your supplier, the modem included with your team can be a DocSIS 3.0 model, which can support your Internet connection.
If you use your own modem, you will probably not be able to see an improvement in the performance, if any, buying a DOCSIS device 3.1 on a PhD 3.0. Given the difference in prices and options available between the two, it would be best to opt for DOCSIS 3.0 in lower level Internet plans.
An autonomous cable modem is at the top of a much larger combined bushing device.
DOCSIS 3.0 has more cheaper options
DOCSIS 3.0 is the cheapest option when buying a combination of modem or modem-rocket. New Docsis 3.0 Modems can cost $ 50 to $ 150, depending on the device you choose and the source you buy, but you may be able to score a used device for less than $ 50. On the other hand, docsis Modems 3.1 can easily cost $ 150 to $ 250 or more.
Manufacturers such as Arris, Asus, Netgear and Motorola have made docsis 3.0 modems for years. These manufacturers also make docsis 3.1, but you will probably have fewer options than you would do if you bought a DOCSIS 3.0 modem.
DOCSIS 3.0 are you obsolete?
As for the latest technology that shapes the way we put us online, yes, Docsis 3.0 is very obsolete. More and more ISP developing plans for various GIGs and the overall tendency of the heaviest use of the Internet in recent years, according to Open vaultA modem Docsis 3.0 will not support the faster speeds that many Internet users go. If you do not need speed, you will most likely be fine with a DocSIS 3.0 modem, especially if you try to save money by avoiding an update.
However, almost all ISPs support docsis 3.1 and often recommend DOCSIS 3.1 to get the most out of your Internet connection.
DOCSIS 3.1 is safer and better for long -term use
Any update of the Internet protocol, such as the transition of docsis 3.0 to 3.1, will include improved security functions. It is usually presented with an improved encryption, so allegedly, a docsis 3.1 modem will be better equipped to secure your information. In addition, the Best router And modem combos equipped with Docsis 3.1 will also include WPA3, a more advanced router security function than older modem routes that can come with Docsis 3.0 and WPA2.
Docsis 3.0 was published in 2006, and Docsis 3.1 arrived in 2013, which is a long time in the world of technology, enough time for initial security measures to become obsolete. Modem and ISP manufacturers release regular security updates to keep your team safe. Still, I would recommend additional Safety software or one Good vpn To help increase your online safety, especially when using a DocSIS 3.0 modem.
Given the increase in domestic internet speed and the need for updated safety, Docsis 3.1 is on the way to completely replaced DOCSIS 3.0. He has not done so completely, mainly because the slowest and cheaper cable plans can still be achieved with docsis 3.0 technology.
Arriving at a nearby house: DOCSIS 4.0
DocSIS 4.0 technology is about to improve cable internet service, but it is not here yet. Since 2023, Xfinity has been the only major cable provider that has begun publishing DOCSIS 4.0 in the country, based on select service areas at Atlanta, Georgia; Springs of Colorado, Colorado and Philadelphia, Pennsylvania.
Unfortunately, if you want to advance the game and buy a docsis 4.0 modem, you are not lucky. Currently, there are no docsis 4.0 modems available for retail purchase, at least none that I have been able to find in a source of trust. According to a Comcast press statementXfinity will continue to unfold the 4.0 modem in the new areas over the coming years.
Background line: Docsis 3.1 will provide you fastest speeds
As docsis 4.0 modems are not yet widely available, your choice of a new or used device will be reduced to versions 3.0 or 3.1. If you register at faster speeds, especially those approaching or exceeding 1GBPS, or you just want a device you know you can use for years, a docsis 3.1 modem is the way to go.
If you settle for a low -level or medium -level cable internet plan, a docsis 3.0 modem will probably meet all your needs and will reach a lower price on DOCSIS 3.1. But you are also likely to pay a premium for these faster speeds so you can also equip your home with a device to leave you.
DOCSIS 3.0, 3.1, 4.0 MODEM FREQUENCES
What does docsis mean?
Docsis means Data on the Cable Service Interface Specifications. This telecommunications rule allows your modem to send the Internet from your cable supplier to your home. There are three different versions of docsis: 3.0, 3.1 and 4.0.
Is DOCSIS 3.1 The best cable modem?
Most cable modems comply with docsis 3.0 or 3.1 technology, as Modems 4.0 are not yet available for purchase throughout the country. That said, most cable internet users will have the option between 3.0 and 3.1. We recommend going with Standard 3.1, as it admits high-speed Internet plans such as Gigabit and multi-gigabit levels. Compared to standard 3.0, Modem 3.1 will offer better online security.
Where is the DocSIS 4.0 cable modem available?
Currently, Comcast’s XFinity is the only major cable internet provider that has begun publishing DOCSIS 4.0 in the country. However, this modem is only available to select areas of Atlanta, Springs of Colorado and Philadelphia. Comcast writes in a press release That Xfinity will continue to unfold this version in new areas over the coming years. Most of them, DOCSIS 3.0 and 3.1 will offer the best availability.
