Arris Surfboard SVG2482AC Vs TG862G. Which is better?

Updated on May 12, 2017

What are both the SVG2482AC and TG862G?

Both the Arris SurfBoard SVG2482AC and Arris Surfboard TG862G are telephony voice gateways or EMTA (embedded multimedia terminal adapter - a combination cable modem and telephone adapter) gateways.

In other words they are a 3 in 1 combo box that includes a fast cable modem, advanced Wi-Fi router and a VOIP box for your telephone connection - all in a single box.

If you do not need a VOIP (Voice Over IP) telephone connection but just a combo box of cable modem and wireless router, then you may want to check out either the Arris Surfboard SBG6782AC or Motorola MG7550 instead.

Between the SVG2482AC and the TG862G, the Arris Surfboard SVG2482AC is the newer of the two and is also major upgrade to the older Arris SBG6782-AC Surfboard eXtreme that was released about two years ago.

This new gateway provides voice and gigabit broadband speed as well as the Reference Design Kit-B (RDK-B) technology. In fact it is one of the first consumer class gateway to incorporate RDK-B technology.

On the Wi-Fi router side, the Surfboard SVG2482AC features 3x3 802.11ac. With 24 download and 8 upload channels, it has a capability of a top speed of 1,300Mbps on the 5GHz band and up to 450Mbps on the 2.4GHz channel; giving a total of 1750 Mbps.

However what you actually get is dependent on the plan you have with your provider and also the availability of that speed in your area.

As with the SBG6782AC, it also has four Gigabit LAN ports for wired devices.

What is RDK-B and how does it benefit you?

With the growth of consumer devices connected to the Internet and the rise of streaming video as well as the Internet of Things (IoT), service providers need to react quickly to adapt and provide faster and more reliable networks to the consumer.

The Reference Design Kit for Broadband (RDK-B) is an open source initiative to standardize software functionalities in broadband devices. This is to enable service providers to efficiently deploy services to a large customer base; thus saving cost and increase profitability!

The RDK-B is an important step forward because it is an integrated open-source software stack which provides a common framework for customers' equipment such as set-top boxes, modems, routers, gateways and other devices to communicate with service providers.

RDK-B solutions provide all needed features to manage complex broadband functions such as Wide Area Networking (WAN), Local Area Networking (LAN), data reporting and management, and home-networking technologies, such as Wi-Fi and Multimedia over Coax Alliance (MoCA).

The service providers use the RDK-B technology to standardize certain elements of these devices; thus enabling them to quickly launch their own new services or customize applications.

The other advantage to RBK-B is the service provider can now actively update the SVG2482AC Gateway's firmware instead having it done by the hardware manufacturer.

For example, Comcast can now actively update the SVG2482AC Gateway's firmware whenever it introduces some new features or implement some bug fixes.

RDK-B can also be used to deliver more with a much better support for IoT devices.

DOCSIS 3.0

Another important technology utilized by both the Arris AVG2482AC and the Arris TG862G is DOCSIS; specifically DOCSIS 3.0.

DOCSIS stands for Data Over Cable Service Interface Specification, an international standard for data transfer over cable TV (CATV) systems. Internet service providers use it to provide internet access using existing hybrid fiber-coaxial (HFC) infrastructure.

CableLabs led a consortium of thirteen networking and electronics companies that jointly developed the DOCSIS standard.

The first version of DOCSIS, Version 1.0, was published in March 1997 while the latest version, DOCSIS 3.1, was published in October 2013, to meet increasing demands for symmetric services such as IP telephony.

DOCSIS 3.0 is a very practical standard as it maintains cross-version compatibility; devices using older versions can communicate with newer devices using the highest supported version common to both devices.

As mentioned earlier, both devices incorporate the DOCSIS 3.0 technology.

Side by side comparison analysis between Arris Surfboard SVG2482AC vs TG862G-CT
Which device is better for your needs?

So which is better for you?

First of all, if you are taking the option of buying and owning your telephony gateway, you will not need to pay Comcast the $10 equipment rental fee anymore.

That comes to $120 per year. Assuming that you opt for the Arris Surfboard TG862G-CT and you buy it from Amazon at the price of $120, then you will start saving after one year.

However if you opt for the Arris Surfboard SVG2482AC, then you will start saving after owning the device for two years.

Both scenarios are only taking into consideration of the dollar value without looking at the features and functionalities yet. Taking into consideration that you are covered by two years' warranty, I feel it makes sense to own either the SVG2482AC or TG862GCT - rather than rent from the service provider. .

Comparing functionalities of both
Comparing functionalities of both | Source

What about functionalities?

Both are DOCSIS 3.0. However the maximum theoretical download speed of the SVG2482-AC is 1,000 Mbps while that of the TG862G is only 343 Mbps i.e. approximately one third of the SVG2482-AC.

The total WiFi speed of the SVG2482-AC at 1,Mbps is approximately six times more than that of the TG862G. This could be due to the fact that the router part of the 2482 is AC while that of the 862 is only N.

On top of that, the SVG2482-AC is RDK-B enabled.

All the better features in the SVG2482AC is to be expected as it has been only recently released as compared to the TG862G which was released a couple of years ago.

What's the catch?
What's the catch? | Source

The catch is that right now the SVG2482AC is roughly twice the cost of the TG862G-CT. So the question is this - are you willing to cough up $120 more to get all these fancy features which may not even available to you at the moment?

Are you willing to future proof yourself for $120? It may only be available to you somewhere along the way within the two years. Then again, what is your service cost?

So you will have to make that decision as only you yourself will know what your needs are.

As for me, it is very clear. I will choose either the SVG2482AC or TG862G-CT as a continuous rental of equipment from Comcast is definitely out.

The Arris Surfboard SVG2482AC is the most ideal if you are looking for the latest and fastest eMTA telephony gateway. You get the technology and speed right away and may not need to change your equipment for some time; thus saving you money in the long run.

Get the TG862G-CT if you know you are not going to need the extra capability of the SVG2482AC for at least two years. Based on the two years' warranty provided, you know you will save at least $120 over the two years if you stay with Comcast and discontinue your rental from them.

      I have WOW! as my internet/phone provider. In Feb 2017 they installed the Arris TG862 gateway. The range is spotty in our house (2 story). What kind of Wi-Fi booster would work with this and would it be any help? My daughter constantly complains that the wifi in her room sucks.

      Is there a gateway compatible w/ Comcast that allows for turning off WiFi when it is not needed? Thank you.

      For both the the SVG2482AC vs TG862G-CT 2 Telephone ports, do you know the Ringer Equivalent Number (REN) for each of the ports on each of the gateways? I have a wired house system wit a few corded phones and would like to understand how much the Telephone ports can drive
