Novel wireless headset uses magnetic communications

22 October 2003 News

A wireless headset based on magnetic communications technology has been introduced. Using so-called LibertyLink technology from Aura Communications, the Cord Free headset from foneGEAR uses an enhanced form of 'near field' magnetic communication rather than conventional radio frequency technology. The result, according to the two companies: a secure communication area that is uniquely owned by each user.

The Cord Free solution is comprised of the headset, and the base station which charges the headset.

While the concepts behind magnetic induction communication have been around for decades, Aura says it is the first company to develop and implement practical solutions capturing the unique benefits of this technology. Conventional radio frequency (RF) wireless communication systems are optimal for sending large amounts of information and communicating over long distances. But this consumes power, creates security issues and results in interference and crowding among devices. LibertyLink's 'near field' magnetic induction communication operates at a low-frequency 13,5 MHz, creating a 3-dimensional 'bubble' that envelops the personal space of each user and as such, is inherently private and secure. The result is an easier to use, lower-cost systems design that makes far more efficient use of power and bandwidth than conventional RF solutions.
