Cornet, a consortium of companies and research centers operating under a program
in the chief scientist’s office of the Industry, Trade and Labor Ministry,
unveiled a breakthrough on Monday for sharing space on the radio spectrum, which
wireless devices rely on to communicate.
“The amount of information we
have to transfer has grown by orders of magnitude, far more quickly than was
forecasted,” explained Bat-Sheva Ovadia, chairwoman of Cornet, which stands for
Cognitive Radio Networks, and executive strategy officer at Telematics
Governments auction off licenses for various entities – such as
radio stations, television broadcasters and cellular phone companies – to use
specific frequencies on the wireless spectrum. A small, unlicensed portion of
the spectrum is cordoned off for use by WiFi devices, which have to share that
part of the spectrum.
Cornet’s “cognitive” technology detects which
frequencies WiFi devices and their users are occupying, allotting them more
efficiently as conditions change and devices connect or disconnect.
like a conversation. If everyone talks at once, nobody will understand anything.
If everyone gets a window of time to speak, it works out,” Ovadia said. “The
system always checks what’s going on around it.”
Each of the institutions
that comprise Cornet – companies including Elbit Systems, Elisra (Tadiran
Spectralink), Telematics Wireless, Wavion/Alvarion Wireless Networks, Altair and
Amimon, not to mention the 13 academic research groups from Technion-Israel
Institute of Technology, Tel Aviv University, Bar-Ilan University and Ben-Gurion
University of the Negev – are incorporating the technology into their products
and marketing them on their own.
Ovadia believes that major players in
the tech world will quickly adopt the innovations, even in the licensed cellular
“I am confident that in a few years we will see cognitive
technology in almost all wireless communications,” she said.
