What Makes the Arris Motorola SBG6700-AC So Fast?

There are many things involved that will help a gateway like the Arris Motorola SBG6700AC to be as good as it is. However the two main technologies used in this gateway that I would like to highlight in more detail here are:

  1. The DOCSIS 3.0 technology on the modem side
  2. The 802.11 AC technology on the wireless router side

DOCSIS 3.0

DOCSIS is the acronym for Data Over Cable Service Interface Specification and it is the international standard to define how data is to be transmitted at a high speed on your existing cable TV.

Standards are normally defined so that manufacturers can have a common guideline for them to follow when they design their products.

So why is DOCSIS important for the modem function of your Motorola SBG6700-AC gateway?

It is important because it helps you channel the data via your provider in such a manner so as to give you the maximum speed.

The use of the latest channel bonding techniques specified in DOCSIS 3.0 allows the Arris Motorola SBG6700-AC to bond up to eight downstream and four upstream channels. This in turn provides an astounding download data rates of speeds up to 343 Mbps and upload speeds up to 131 Mbps.

Compare to the previous version of DOCSIS, that is DOCSIS 2.0; the DOCSIS 3.0 cable modem as it is able to download up to 8 times faster than the older DOCSIS 2.0 cable modems.

Oh, by the way, you pay for what you get. So you have to subscribe to the appropriate broadband package otherwise your Arris SBG6700-AC may be underutilized; unless of course, your intention is future proofing.

802.11 AC

While DOCSIS helps in the download speed of the cable modem function of the Arris Motorola SBG6700-AC, the 802.11 standard governs the speed of the wireless router side.

You may have seen older routers with numbers such 802.11 A,B, G etc but these can be considered outdated as they have been superseded by the "N" and "AC" standards.

Right now the "N" standard is very popular but it will be a matter of time before it becomes obsolete as well.

You will understand why if you look at the comparison of the speeds that can be managed by each of the standards below:

  • 802.11b can go up to 11 megabits per second (Mbps)
  • 802.11a and 802.11g can go up to 54 Mbps
  • 802.11n up to 300 Mbps
  • 802.11ac up to 1,000 Mbps or 1 Gbps

Here is a chart on the speed and theoretical range:

"AC" is 3X faster than the "N"
"AC" is 3X faster than the "N" | Source

Hence the AC at 1,000 Mbps is roughly 3 times faster than the N.

With the proliferation of online streaming, on-line video gaming with realistic pictures, bigger and bigger files to transferred, the "AC" device at 3 times faster than the "N" will definitely be the preferred choice.

You Also Get Technologies Such As

  • 2.4/5.0 GHz Dual-band Concurrent Wifi
  • 2x2 MIMO antenna array on 2.4 GHz and 3x3 MIMO antenna array on 5 GHz spectrum to enhance wireless connectivity
  • Wi-Fi beamforming
  • 2 Gigabit Ethernet Ports – 10/100/1000 Mbps
  • Support for IPv4 and IPv6 which are the Internet's latest standard

How Do Dual Bands Help?

Dual band routers are especially useful when you have crowded air waves.

It works by having two different bands for multiple end user devices and operator segregation of video distribution. They generally transmit on the 5 GHz and 2.4 GHz wireless bands.

The 2.4 GHz is more popularly used and hence susceptible to interference from devises such as other Wi-Fi access points, microwave ovens, cordless phones, Bluetooth devices, baby monitors, etc. All these increases interference and degrades performance.

By the way, all 802.11B and G devices run on 2.4GHz only.

The 5GHz channel on the other hand is much cleaner with less interference. As such it is more suitable for applications like Video streaming and Gaming which are very sensitive to packet loss and delays.

It is important to take note the the Motorola SBG6700-AC has a simultaneous dual band function. What this means is that you can use both bands simultaneously and the dual-concurrent radios ensures that you will have an interference-free network.

What is WiFi Beam Forming?

Beam forming technology helps especially when you have many devices such as smartphones, tablets, notebook computers etc that need to be connect to the internet.

A beam forming wireless router works by directing its signals toward each mobile client as compared to a normal wireless router that broadcast data radially in all directions (see the diagram on the right). In this way the beam forming wireless router ensures that it targets its data transmission towards the mobile clients where ever the clients are.

The additional benefit of the the focused signals is that it also increases the network's range as well as bandwidth utilization.

Beam forming in the Motorola SBG6700-AC is achieved through the use of its 2x2 and 3x3 internal MIMO (multiple-input, multiple-output) antennas respectively on both the 2.4 GHz and 5 GHz bands.

Can I Connect My Phone to the Arris SBG6700-AC?

No. Sorry, you cannot do that because it does not have a phone jack.

If you really must have a phone connection, then you should look at the Arris TG862G if you are looking for a gateway.

If you are looking for a modem only that allows you to your phone to it, then look at Arris TM822G.

On the other hand if you really like the Arris Motorola SBG6700-AC and would also like to make calls with it, then a way to do that is to connect a VOIP device like the Ooma Telo to it. Spend an additional one time cost of less than $100 to get an Ooma and you can make and receive crystal clear free calls via your SBG6700-AC.
