Alcatel-Lucent simplifies installation of 100M bps VDSL

Operators no longer have to upgrade all modems to deploy noise cancellation technology

Alcatel-Lucent has upgraded its implementation of the VDSL2 vectoring noise cancellation technology in order to make it easier to implement, and as a result let operators offer higher broadband speeds over phone lines to more users.

While fiber is the ultimate broadband bearer for high speeds, copper and old telephony lines still dominate with over 60 percent of the market, according to ABI Research. Fiber will have about 13 percent of the market by the end of the year, it said.

To help keep DSL relevant, vendors are working on a number of technologies, including vectoring, which improves VDSL performance by removing crosstalk interference.

The end result is download speeds of up to 130M bits per second over a distance of 400 meters. But Alcatel-Lucent prefers to say it can offer 100M bps over the same distance.

Early next year, operators will be able to combine two lines with vectoring to double the speeds, according to Alcatel-Lucent.

It has been about a year since Alcatel-Lucent introduced vectoring. At that time operators needed to make all modems compatible with the technology to implement it, even those that didn't subscribe to the faster speeds. But that hurdle is now removed with the introduction "Zero Touch Vectoring".

"The feature makes it easier for operators to deploy vectoring in the field. They no longer have to take care of every modem before upgrading," said Stefaan Vanhastel, director of fixed access marketing at Alcatel-Lucent.

Vectoring works by continuously analyzing the noise conditions on copper lines, and then creates a new anti-noise signal to cancel it out, much like noise cancelling head sets, according to Vanhastel.

So far, Alcatel-Lucent has six customers for its vectoring products, compared to more than 90 for its regular VDSL equipment. But there is a strong interest in the technology, according to Vanhastel.

That statement is backed up by a survey conducted by Infonetics Research. The survey states that around 40 percent of service providers plan to deploy VDSL2 with system-level vectoring.

Currently, operators are conflicted over how much to eventually invest in fixed broadband networks and services, according to Jeff Heynen, directing analyst for broadband access and pay TV at Infonetics. The transition to next-generation fiber-based fixed access technologies -- including 10G EPON (Ethernet passive optical network) and variants of WDM-PON -- will take longer than many in the industry had hoped, he said in a recent statement.

More than one-third of the world's total households are expected have a fixed broadband connection at the end of 2012, according to ABI.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
