Conventional wisdom seems to be that rural America moves a little slower than other parts of the country. That isn’t necessarily always true, however – especially not in the case of rural areas served by Alcatel-Lucent’s ultra-broadband gigabit technology.
In fact, such areas are among the country’s elite when it comes to ultra-fast connectivity, as highlighted in a recent Alcatel-Lucent paper, Municipality Rural Ultra-Broadband .

There was a time when fiber-to the-home was seen as the future of broadband. But all that changed with the introduction of VDSL2 vectoring.
“With a single innovation, the market shifted,” noted Alcatel-Lucent colleagues Paul Spruyt and Dr. Stefaan Vanhastel in a recent blog post, The Numbers are in: Vectoring 2.0 Makes G.fast Faster. “Copper became a valuable commodity again as operators began using their copper assets to deliver fast broadband speeds faster.”
Making that copper even more valuable potentially is the new G.fast standard.
G.fast can increase aggregate bit rates over copper loops shorter than 250 m to fiber speeds of more than 1 Gb/s, the authors explained. It also delivers a cost advantage over deploying fiber directly to the home.
The trouble is that G.fast suffers from crosstalk even more than VDSL2. Tests by Bell Labs on older, unshielded cables in Austria showed that G.fast reached speeds of 500 Mb/s over 100 m when a single line was active, but they fell to a measly 60 MB/s when crosstalk was introduced as a result of a second G.fast line being added.
