Difference Between DOCSIS 3.0 VS 3.1

When you purchase a modem router combo, you will see the mention of DOCSIS 3.0 or DOCSIS 3.1. We have already told what DOCSIS means. We suggest avoid going for modems with less than DOCSIS 3.0 in order to avoid any issues or low speed. It is because modems lower than DOCSIS 3.0 support would not support most of the internet plans.

Moreover, DOCSIS 3.1 supporting modems may not be essential for all the plans, but they are perfect for most of the devices.

What DOCSIS 3.0 Means?

DOCSIS 3.0 is one of the most used versions available today. It offers decent speed and usually offers till 1 Gbps speeds. For this reason, modems with DOCSIS 3.0 are unable to reach their maximum performance.

Downstream and upstream channels play a pivotal role in the overall modem speed. DOCSIS 3.0 modems usually come with 8, 4, or 2 upstream channels at maximum depending on the model you select. The advanced models are integrated with up to 24 downstream channels.

What Does DOCSIS 3.1 Mean?

DOCSIS 3.1 is a future-proof technology offering great internet speed. It is compatible with most of the modern internet cable service providers.

In comparison to DOCSIS 3.0, DOCSIS 3.1 is more powerful. Modems integrated with DOCSIS 3.1 deliver till 10Gbps speed. If you want your present modem to precisely cater to your entire upcoming and future needs, you must go for modem router combo with DOCSIS 3.1 technology. Such modems are useful for today’s internet speeds.

Disadvantages of DOCSIS 3.0

The biggest drawback of DOCSIS 3.0 it offers limited features and speed. There are even modems integrated with DOCSIS 3.0 that are equipped with Puma6 chipset that are highly flawed.

Moreover, DOCSIS 3.0 is not compatible with the future internet technology. For this reason, it may not serve your present and future needs to the fullest.

Disadvantages of DOCSIS 3.1

The limitation with DOCSIS 3.1 is its price. The modem router combos incorporated with this technology are expensive, and if you are looking for affordable options, you may not be able to grab it.

Also, there is no certainty on how long DOCSIS 3.1 will continue to serve as if more speed is required then a new technology will be introduced.

But DOCSIS 3.1 modem will serve you for at least the next five years.

Benefits of DOCSIS 3.1 over DOCSIS 3.0

DOCSIS 3.1 is beneficial over DOCSIS 3.0 in various aspects.

  1. AQM – The full form of AQM is Active Queue Management that makes sure there is very little delay of network as the data traffic is managed within the home network. As a result, those using DOCSIS 3.1 never experience lag when streaming videos, playing games, downloading movies, and others. Even the resolution display is better in DOCSIS 3.1 than DOCSIS 3.0.
  2. Speed – The speed offered by DOCSIS 3.1 is higher than that offered by DOCSIS 3.0.
  3. Low Energy Consumption – Modem routers with DOCSIS 3.1 consume less energy in comparison to DOCSIS 3.0 thereby resulting in enhanced modem efficiency.
  4. High Capacity – DOCSIS 3.1 offers a great network capacity as it has the power to transmit 50 percent higher data over the same panel in comparison to DOCSIS 3.0 technology.
