CCww, CCasia and Silicon Laboratories Announce
GSM/GPRS Reference Design and Services

31 October 2005: Bournemouth UK, Taipei Taiwan and Austin TX, USA

Communications Consultants Worldwide Ltd (CCww), a leader in wireless protocol stack solutions, CCasia (Winity Technology Inc), a leader in wireless system design
and integration, and Silicon Laboratories Inc. a global leader in high-performance mixed-signal IC solutions announced today that their partnership has completed the
integration of a GSM/GPRS reference design for licensing to handset manufacturers.

The reference design is configurable for use in a range of handsets from entry-level GSM phones to high-end Feature and Smart Phones. At the core of the design is Silicon Laboratories' AeroFONE™ single-chip phone, combining the conventionally separate digital and analog base-band and RF transceiver into an innovative single-chip design. CCww's high-performance, resource-efficient GSM/GPRS stack has been ported and validated by the partners to create a complete and configurable reference design.

One configuration of this design provides a low-end GSM phone that is well-positioned to provide rapid time-to-market coupled with very competitive low cost in manufacture. At the other end of the scale, CCasia can provide a complete feature-phone design to
include: graphical MMI, memory file-system, 2 M-pixel camera, MP3 player, VoIP, Bluetooth, GPS, IM and more to create a high-specification feature phone that provides an unbeatable combination of fast time-to-market and low-cost BOM.

These unique advantages are enhanced further by a range of services derived from
CCasia's exceptional experience in field trials (more than 50 networks world-wide) and optimization of handset production.

"We are delighted to be chosen by Silicon Laboratories to provide our protocol stack solutions with the world's most integrated wireless IC", said Richard Carter, Managing
Director of CCww. John Wong, CEO of CCasia added, "we have created the most competitive handset solutions and will ensure our customers achieve early production
with targeted features and low-cost BOM."

"We are confident that the technology in AeroFONE combined with the technology solutions and support from CCww and CCasia is an unbeatable combination," said Dan Rabinovitsj, vice president of Silicon Laboratories. "We're taking wireless to a new level of integration, performance and cost effectiveness."
