The foneGEAR chord free headset "near field" magnetic communications - induction - supports 25 hours of talk time on one AA battery and runs on the low frequency 13.5MHz band. Bluetooth is on the 2.4GHz band which, according to the firm, seems to have the world+dog clogging up its space.
The firm told the INQUIRER that you would have to get really close to someone using a similar device before you'd experience interference.
Also, claimed Aura, the technology would have widespread application for MP3s and car phones. It also isn't as fiddly to set up as Bluetooth.
The Department of Defense (DOD) and NASA are both interested in the technology, which is non-progagating. Aura said it has made evaluation products for DOD in battlefield conditions.
The firm said that unlike radio frequency (RF) technologies, the power generated is about 100 nanowatts. The range of the headset is about four feet.
It will go on sale in big shops in North America in the next few weeks, and in Europe as soon as the CE marks have been recorded.
Aura has designed the Liberty Link system on a chip and that's in production quantities. It only needs a few passive components, an EEPROM, an antenna, a crystal and a battery to put together a wireless node. µ
