AT&T is late to the gigabit game, but you can pay them for "privacy"

Kansas City got Google Fiber back in 2012 and not surprisingly a lot of users jumped to this ~$70 service from their current ISPs the moment they could.  Two of the incumbent ISPs suddenly came to the realization that there was demand for broadband at this speed and turned on some of their already laid and configured fiber connection so they could start to offer actual broadband and now several years later AT&T discovered that they would need to do the same to be able to attract customers in that market.  The fiber has lain dormant for quite some time as most ISPs have argued that there was no demand for that level of connectivity; at least until Google offered it and customers left them in droves proving that the demand had always been there.

From The Register we hear that AT&T now offers $70 for a1Gbps connection, an additional $50 will get you TV and you can even bundle home service into the deal if you wish.  For an additional $29 per month AT&T also offers not to log everything you do on the web over their connection, something which Google does not offer.  This makes for an interesting discussion as most surfers no longer blink at Google the search engine tracking what they do online, but what about Google the ISP; does that create a different gut reaction?  Then again considering AT&T's loose definition of unlimited, what do they mean by privacy or even gigabit for that matter?


"We've moved quickly to bring more competition to the Kansas City area for blazing-fast Internet speeds and best-in-class television service," said John Sondag, president of AT&T Missouri, without apparent irony."

And now for something a little different from what we normally report on. is a telecom standard which allows really fast (capable of over a gigabit) communication over moderate distances (~a quarter of a mile) using standard telephone cable. The point of this standard is to avoid installing infrastructure between the end of a fiber roll-out to the neighborhood and the insides of every individual home.


Eh, it looks enough like a phone cord.

The hope that it will trigger another wave of infrastructure improvements for upcoming "Ultra-HD" (4K and 8K) video services and online storage solutions. Installing fiber seems to be treated more like self-obligation than a necessary upgrade. This solution would not even require a technician to enter the home much like we currrently have with ADSL2.

I do have lingering concerns, however, with the reliability of fiber-optic networks. Copper infrasturcture was designed to be resilient. I wonder how reliable will be compared to this legacy network in areas prone to natural disaster. It sounds like standard telephone services will, unlike a fiber-to-the-home solution, function in a power outage at least at the home level but what about one localized to that neighborhood? Then again, this is definitely not an area of my expertise.

The ITU wants to be finalized "as early as" April 2014.

G.Fast Delivers Gigabit Broadband Speeds To Customers Over Copper (FTTdp)

Alcatel Lucent has been working on a new broadband technology called G.Fast that is currently undergoing ITU (International Telecommunications Union) scrutiny and may be ready to implement as soon as 2015. G.Fast is a technology that builds upon VDLS2 and is the next step between the currently-popular FTTN (Fiber To The Node) and true fiber FTTH (Fiber To The Home) internet services. Alcatel Lucent’s G.Fast technology is rated for speeds up to symmetrical 1 Gbps over copper lines up to 200 meters and 500 Mbps at up to 300 meters.

G.Fast is currently being tested by Telecom Austria and is being evaluated as a standard by the ITU. G.Fast requires fiber to be pulled closer to consumers, but avoids the massive expense of doing true fiber runs to each individual home. Unlike traditional DSL which is served from a central office up to miles away, or newer VDSL technology like AT&T's U-Verse service that is served from a DSLAM that is located about a mile from customers, G.Fast serves customers from a fiber distribution point that is a maximum of 300 meters away from customers. In the latter two cases, the internet connection is fiber up to the DSLAM or distribution point after which it uses the existing copper phone lines to reach customers' homes. The G.Fast distribution point is about the size of a large shoebox and can be mounted on telephone poles or underground.

G.Fast implements pair bonding, vectoring, and phantom mode techniques (more information, PDF) in addition to a physically closer fiber connection (internet speeds drop off dramatically as copper cable length increases due to cross talk on the cables, interferrence from other RF sources, and other factors). Specifically, G.Fast is able to use multiple physcal copper pairs (pair bonding) along with multiple virtual pairs per each physical pair (phantom mode), and an active noise monitoring and cancelling system to reduce cross talk and interferrence (vectoring). Additionally, G.Fast uses a surprising 100Mhz of spectrum over the copper pair(s) and fancy modulation techniques to wring all the speed possible out of existing telephone lines. For comparison, traditional old-school DSL that you would get from your local telephone provider uses less than a MHz of spectrum, and the latest VDSL2 technologies use around 1MHz of RF spectrum! There is an interesting problem with G.Fast beyond punching all this through the cables, and that is possible issues with FM broadcasters (radio stations) that use RF spectrum between 87.5MHz and 108Mhz. The Register notes that ISPs that implement G.Fast will have to work around the specific FM frequencies actually used in the local area to avoid interferrence. That suggests that operators may not be able to use the full 100MHz of spectrum in the standard, but it would still be a huge step up from VDSL. The site further explains that even if the copper lines are buried underground, it could still cause issues with FM broadcasts as the 200-300 meter line makes for a massive antenna.

Another point in favor fo G.Fast is that it is designed to be a customer installed technology in the sense that customers will be able to plug in their modems to the standard phone jack and recieve service. (Ideally, this would mean no need for technicans to do so-called "home runs" to get the best speeds, but if it is needed with U-Verse it may still be needed for G.Fast, especially in older apartment buildings.)

The ITU is currently looking at G.Fast and working towards a standard along with developer Alcatel Lucent and various telecoms interested in implementing the technology. According to Frank van der Putten of the ITU, G.Fast could be approved as soon as early 2014 with hardware supporting it available in 2015.

G.Fast is by no means the end-all-be-all of internet connections for home users, but it is a massive performance leap ahead of current DSL technologies and thanks to competition from Verizon FIOS, Google Fiber, local municipalities building out their own fiber neworks, and cable companies (in the US at least, where internet over coax is common), G.Fast may be economical enough that telecos are willing to upgrade their networks to head off these competitors all while moving their true fiber networks all that much closer to people's homes and to the (hopefully/ideal) eventual implementation, and final upgrade to, Fiber to the Home connections.
