ASSIA Licenses its DSL Phantom Mode Technology

ASSIA Inc. is making available licenses to essential patents for DSL Phantom Mode Technology. DSL Phantom Mode significantly increases the speeds of DSL services provided over multiple copper pairs.

The key ASSIA invention that makes Phantom Mode communication practical is the DSL modems' discrimination between the deliberate phantom communication signals and the resultant undesirable crosstalk that these phantoms create through electromagnetic (radio) coupling between the pairs of wires. ASSIA's inventors discovered that this crosstalk could be removed by the application of vectoring, making Phantom Mode communication practical.

"Recent Phantom Mode product announcements, advertising speeds of more than 800 Mbps, substantiate the importance of this technology, which ASSIA developed some years ago," said Dr. John Cioffi, ASSIA's Chairman and CEO. Major DSL vendors, including Alcatel-Lucent, Ericsson, Huawei, and Nokia Siemens Networks, have recently demonstrated or announced Phantom Mode products.
