*** Zyray Wireless introduces SPINNERchip 1.1
(February 23)

Zyray Wireless introduced SPINNERchip 1.1, a dual-mode (GSM/GPRS &
WCDMA) multi-antenna diversity chipset for handsets, at the 3GSM World
Congress in Cannes.

Zyray's SPINNERchip SD is the first in a series of Space-Time Processing
products for mobile handsets, which the company plans to release.

SPINNERchip's Single Channel MIMO implementation, which utilizes two
receive antennas combined with Zyray's Smart Diversity, Optimum
Combining and Adaptive Interference Cancellation techniques, provides an
average improvement of 3.5 - 4.0dB in Signal to Interference Noise Ratio
over single antenna solutions.

SPINNERchip is integrated as an add-on WCDMA baseband processor coupled
with existing chipsets to provide dual-mode (GSM/GPRS & WCDMA) and multi
mode (GSM/GPRS/EDGE & WCDMA) solutions.
