GCT Semiconductor & Whiznets offer fully-integrated mobile VOIP
over WIMAX solution for Android platform

Las Vegas, NV, January 7, 2010 - GCT® Semiconductor, a leading supplier of Mobile WiMAX™ solutions to the global market, and WhizNets, the leading provider of embedded wireless networking solutions and services to clients worldwide, today announced the completion of an Android-based mobile platform with WiMAX connectivity. WhizNets also announces a VOIP solution for GCT's WiMAX Android platform.

GCT and WhizNet's new WiMAX Android platform represents a key milestone as it enables Android-based portable devices to connect to mobile WiMAX networks. GCT's market-proven WiMAX drivers are fully integrated with the standard Android framework. The integration of a common WiMAX API for interface control, and a connection manager, makes it a completely integrated solution for ODM/OEMs interested in building Android-based WiMAX devices. In addition, WhizNets' integration of the VOIP stack on this WiMAX Android platform allows ODMs to serve both voice and data needs over a WiMAX connection.

"With the industry actively working toward the creation and delivery of WiMAX infrastructure to serve the need of an increasing number of mobile users and value-added mobile services, manufacturers will need to develop advanced mobile devices that take advantage of the greater bandwidth, range and integrated voice and data capability of WiMAX," said Atul Garg WhizNets' CEO. "We've created a complete ecosystem dedicated to mobile Android VoIP over WiMAX by collaborating with the leading WiMAX chipset maker, GCT, in order to offer the most matured WiMAX solutions and Android system/devices integration services to OEM/ODM's and operators. Our goal is to accelerate integration of WIMAX in Mobile Platforms to get new products to market efficiently and effectively."

"It's been a pleasure working with the WhizNets team to successfully complete Android porting on GCT's WiMAX platforms," commented Dr. Kyeongho "KH" Lee, President and CEO of GCT Semiconductor. "GCT's single-chip WiMAX solutions continue to offer the lowest power consumption and flexible software architecture. GCT is well-positioned to enable increased deployments of portable Android devices globally."

The Android platform is powered by GCT's compact solution, GDM7205 (for 2.3GHz and 2.5GHz), GDM7213 (for 3.5GHz), or GDM7215 (WiMAX+WiFi) . These single-chip, highly integrated, low-power devices minimize the number of external RF front-end components. They also include a Mobile WiMAX baseband with high performance dual-processors, and an impressive array of peripherals for connectivity. These single-chips satisfy the high demands of multimedia data processing and wireless connectivity, and stretch battery life for the longest run time.

Presently, WhizNets has successfully ported it's Android full software stack (including operating system, middleware and applications) to various development platforms. WhizNets is now developing Android projects for various mobile handset applications. WhizNets' Android software solution includes Android development for a new supported hardware platform;
development of OEM device drivers; customization and development of middleware and application framework; as well as customization and development of user applications.
