New Spin on Dual Mode 3G Handsets

The rapid development of dual mode GSM/GPRS and WCDMA handsets is a significant step closer following the introduction of Zyray Wireless' SPINNERchip 1.0 WCDMA baseband processor 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 baseband
solutions, Zyray's SPINNERchip 1.0 single chip WCDMA FDD baseband processor
began sampling last month. The solution uses a standard memory interface to
connect to existing GSM/GPRS baseband processors.
"As an add-on to an existing GSM/GPRS terminal design, SPINNERchip 1.0
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 Zyray Wireless.

"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."

SPINNERchip 1.0 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.
SPINNERchip 1.0 is a 3GPP Release 99 March 2002 compliant FDD baseband
processor, 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.
SPINNERchip 1.0 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. SPINNERchip 1.0 is supplied with a
comprehensive customer development package that includes the SPINNER
evaluation board.
