ZyrayWireless: Zyray Wireless puts a new spin on dual mode 3G handsets


San Diego, CA, Feb 14, 2003 (M2 PRESSWIRE via COMTEX) -- The rapid development
of dual mode GSM/GPRS and WCDMA handsets is a significant step closer following
the introduction of ZyrayWireless` SPINNERchip1.0 WCDMA basebandprocessor
solution. Sampling began ahead of schedule and a complete dual mode WCDMA &
GSM/GPRS solution will be demonstrated at the 3GSM World Congress in Cannes.

Proven to connect to a majority of market-leading GSM/GPRS basebandsolutions,
Zyray`sSPINNERchip1.0 single chip WCDMA FDD basebandprocessor began sampling
last month. The solution uses a standard memory interface to connect to existing
GSM/GPRS basebandprocessors.

"As an add-on to an existing GSM/GPRS terminal design, SPINNERchip1.0 provides
handset manufacturers with the lowest-risk, lowest-cost path to dual-mode
GSM/GPRS and WCDMA handsets,"said Werner Sievers, President and CEO of
ZyrayWireless. "This solution is key to reducing a customer`s development cycle
time, maximizing hardware and software reuse and reducing development costs.
Significant BOM (Bill of Materials) savings can also be achieved."

SPINNERchip1.0 can provide handset manufacturers with a time advantage of up to
12 months and can reduce the cost of a handset development project by as much as
$3 million. By utilizing this dual chip strategy, per handset savings are
estimated at between $10 - $20.

SPINNERchip1.0 is a 3GPPRelease 99 March 2002 compliant FDD basebandprocessor,
supporting 384kbps operation in uplink and downlink and integrating all
functionality required for WCDMA operation into a single chip. The chip includes
support for WCDMA ciphering, a programmable analog I/Q RF interface, and an
optional USIM interface.

SPINNERchip1.0 includes on-chip programmable power management and proprietary
interference cancellation algorithms that provide enhanced Bit Error Rate
performance at minimum power consumption. Currently available in a 16x16mm
280-pin LFBGA test package, the chip will be supplied in a 180-pin, 10x10mm
LFBGA production package. SPINNERchip1.0 is supplied with a comprehensive
customer development package that includes the SPINNER evaluation board.

Zyraywill demonstrate SPINNERchip1.0, Stand F33, Hall 2 at the 3GSM World
Congress, February 18th - 21st, Cannes, France.
