While the concepts behind magnetic induction communication have been around for decades, Aura 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. However, this consumes power, creates security issues through its widespread broadcasting of information and results in interference and "crowding" among devices. A good example is in the 2.4 GHz band where simultaneous operation of a portable phone, WiFi network and Bluetooth headset is frequently not possible without severe degradation of Quality of Service.

In sharp contrast, LibertyLink's magnetic communication operates in the low-frequency industrial, scientific and medical band at 13.5 MHz, creating a 3-dimensional ‘bubble’ that envelops the personal space of each user and is -– by the laws of physics –- 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.

By selecting a technology that limits the range and bandwidth to only what the application requires, Aura achieves a very substantial savings in power with all of the simplicity advantages of LibertyLink: dedicated communication channels, no bandwidth sharing, complete frequency re-use between bubbles, worldwide regulatory flexibility, and reliable coexistence with WiFi, CDMA, TDMA. and GSM transmissions.

In streaming voice and audio communications in personal electronic devices, Aura's magnetic communication offers better power, cost and quality-of-service than any other wireless technology, including WiFi, 450 and 900 MHz RF, and Bluetooth.
