Telekom Austria Deploys Alcalu VDSL2 Vectoring Technology

VIENNA – The Telekom Austria Group announced that its domestic subsidiary, A1, will be the first network provider worldwide to deploy Alcatel-Lucent's vectoring technology. This technology, which eliminates crosstalk on DSL lines, greatly accelerates data transmission speeds over existing copper loops. As a result, A1's existing copper network will now be able to achieve data transmission speeds of up to 100 and 50 Mbps at distances of up to 300 meters and 800 meters respectively.

A1 will introduce the vectoring technology in Korneuburg, lower Austria, and plans a comprehensive countrywide rollout for the second half of 2012.

Vectoring technology helps meet ever-increasing subscriber appetites for broadband and will also help Telekom Austria achieve goals for universal broadband access outlined in the EU Digital Agenda for Europe. According to EU guidelines, all European households should be provided with high-value multimedia services, which require broadband connections with transmission speeds of at least 30 Mbps by 2020 - which, in turn will require both new FTTH networks and optimization of legacy networks. Vectoring technology fully leverages the still-untapped potential of copper lines, which in many cases exceeds demand.

Walter Goldenits, CTO of A1, says, “The still untapped potential of copper lines is incredibly impressive. Since the late 1990s, when private households started to use modems for data transmission, we have been able to reach a thousandfold increase in transmission capacities of existing copper lines. We are currently facing a dual challenge: On the one hand, we have to invest in the further rollout of our high-performance fiber optic network going forward, and on the other, we have to provide our customers with a full-coverage broadband network with ever-increasing bandwidths starting from today.”

Vectoring technology fulfills these requirements by providing noise cancellation that minimizes the interference among parallel copper lines within a cable. This interference, called crosstalk, is one of the most significant factors reducing transmission performance within copper networks. Vectoring works much like the noise-cancelling technology used in headphones - it produces a clean signal for each line by measuring the crosstalk from all other lines and generating anti-phase signals to cancel out the crosstalk signal, thus, resulting in almost zero noise while considerably improving copper line performance and significantly boosting data transmission speeds.
