What is a DOCSIS 2.0 modem?

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system.

How fast is a 24×8 modem?

* 1029/246 Mbps is the maximum nominal download/upload speed for 24×8 DOCSIS 3.0 cable modems. Actual speeds depend on a number of factors including the speed of your cable modem service, and will typically be slower. Speeds cannot exceed the speed of the Gigabit Ethernet port.

What is the fastest DOCSIS modem?

What is the best gigabit modem? The Motorola MB8600 is the best modem for cable internet speeds of 1,000 Mbps or faster. It’s compatible with DOCSIS 3.1 standards, has four Gigabit Ethernet ports for link aggregation, and delivers 32×8 channel bonding if used on a DOCSIS 3.0 network.

Is Docsis 3.1 fast?

And that’s where DOCSIS 3.1 comes in. DOCSIS 3.1 standard supports up to 10 Gbps download and 1 Gbps upload speeds which is up to 10x faster than DOCSIS 3.0.

Is DOCSIS 3.1 fast?

What does 16×4 DOCSIS mean?

A 16×4 modem has 16 downstream channels and 4 upstream channels, with theoretical speeds of 608 Mbit/s downstream and 108 Mbit/s upstream. Modems with more channels usually have better hardware overall, and speeds of about 60% of the rated performance are likely.

Do modem channels matter?

Benefits of More (or Faster) Channels The higher the DOCSIS standard tier will also determine how many download and upload channels your cable modem will support. Learn all about DOCSIS here. The more channels your cable modem supports, the more data your computer or device can quickly send and receive.

What is a fast speed for a modem?

DOCSIS 3.0 (and newer 3. x) cable modems support connection speeds over 150 Mbps. Many cable internet providers sell plans for service that runs faster than 38 Mbps (typically, 50 Mbps for downloads).

Can I use DOCSIS 2.0 with Comcast?

Any cable modem that supports the DOCSIS standard will work with Comcast – but keep in mind that DOCSIS 2.0 is limited to a single channel, so you will be stuck at <40mbps. If you’re paying for speeds faster than that (or plan to at any point in the future) you’ll want to get a DOCSIS 3.0 modem.

Is DOCSIS 3.0 going away?

And, of course, we need to keep in mind that DOCSIS 3.0 is an old technology that will eventually become obsolete. When your ISP moves to DOCSIS 3.1 for good, you will need to replace your 3.0 modem.

What is 24×8 DOCSIS?

A 24×8 modem has 24 downstream channels and 8 upstream channels, for theoretical speeds of 912 Mbit/s downstream and 216 Mbit/s upstream. The real-world performance of a 24×8 cable modem is around 60% of its rated speed. This means it should be suitable for ultra-fast cable connections.

When should I upgrade my modem?

Typically, you should look to upgrade or replace your cable modem every two to four years. Newer cable modem technology, such as DOCSIS 3.1, can have a variety of improvements, including faster download speeds, faster uplink speeds, enhanced streaming capabilities, DOCSIS 3.1 capabilities and more.

What is the latest DOCSIS?

DOCSIS 4.0 is the latest DOCSIS standard. Its specification was first issued in 2019. DOCSIS 4.0 is not yet used in any released products, but will be more widely adopted in the future.

How many DOCSIS channels do I need?

It also depends on your modem’s DOCSIS tier. You will want a cable modem that is either a DOCSIS 3.0 or 3.1 device for the fastest speeds. If you want max speeds up to 1 Gbps (1000 Mbps) or faster, you will want a modem that supports 24 or 32 downstream channels.
