Adtran lays groundwork for superfast broadband over copper

The first commercial networks are expected next year

US telecom equipment vendor Adtran has developed a technology that will make it easier for operators to roll out broadband speeds close to 500Mbps over copper lines.

The conventional wisdom is that copper is dying out and fiber is ascending. However, the cost of rolling out fiber is still too high for many operators, which instead want to upgrade their existing copper networks (and in some cases fiber simply can't be installed). So there is still a need for technologies that can make use of copper networks and complement fiber.

Adtran has developed what is calls FDV (Frequency Division Vectoring), which enhances the capabilities of two of these technologies -- VDSL2 with vectoring and G.fast -- by enabling them to better coexist over a single subscriber line, the company said.

VDSL2 with vectoring, which improves speeds by reducing noise and can deliver up to 150Mbps, is currently being rolled out by operators, while G.fast, which is capable of 500Mbps, is still under development.

The higher speeds are needed for applications such as 4K video streaming, IPTV, cloud-based storage and communication via HD video.

FDV will make it easier for operators to roll out G.fast once it's ready and expand where it can be used, according to Adtran.

The first G.fast deployments will happen in the middle of 2015, a spokeswoman for Adtran said via email. The underlying standard is expected to be adopted by the end of the year. Once that happens, chip makers and equipment makers like Adtran can develop products for commercial deployments, she said.

The technology increases the bandwidth by using more spectrum. G.fast will use 106MHz of spectrum, which compares to the 17MHz or 30MHz used by VDSL2.

The development of G.fast is currently at a point where vendors are trying to show they are the best alternative for future upgrades. Recently, rival Alcatel-Lucent demonstrated a prototype technology called XG-Fast, which is capable of 1Gbps for upload and download traffic, as well as 10Gbps in download speeds when using two copper pairs, it said.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
