GCT and Green Packet Demonstrate World's First Seamless WiMAX-WiFi Connection Manager

SINGAPORE--(Business Wire)--
GCT Semiconductor, a leading supplier of mobile WiMAX solutions to
the global market, and Green Packet Berhad (Green Packet), a leading
developer of next generation mobile broadband and networking
solutions, today announced collaboration to bring the world's first
intelligent connection management solution that delivers seamless
connectivity and handover between WiMAX and WiFi. The Green Packet
"Intouch Connectivity Manager" integrates Green Packet's Mobile IP
solution with GCT's GDM7215, the industry's first single-chip solution
supporting both mobile WiMAX IEEE 802.16e Wave 2 and WiFi 802.11 b/g.

"A seamless broadband environment is now a reality. It is no
longer just an idea on paper or a vision for the future," said Kelvin
Lee, Senior General Manager of Green Packet. "With Green Packet's
"Intouch Connection Manager" users enjoy uninterrupted connections as
the solution intelligently and transparently switches between WiMAX
and WiFi according to connectivity rules set by the user or the
operator. Our intelligent connectivity management solution is aptly
named Intouch to correspond to the fact that users will never have to
experience a 'disconnect'."

Green Packet's "Intouch Connection Manager" also supports multiple
connection modes such as WAN and LAN in addition to WiMAX and WiFi.
Intouch is coupled with lifestyle features such as communication
services, information and entertainment into a single client. This
unique combination is aimed at providing WiMAX operators with service
differentiation factors allowing them to gain revenue not only from
network access but from value-added services as well.

"GCT's GDM7215 single-chip WiMAX plus WiFi integrated circuit
enables a physically smaller solution, lower power consumption and
reduced bill-of-materials," commented Dr. Kyeongho (KH) Lee, President
and CEO of GCT Semiconductor. "WiMAX plus WiFi systems containing our
chip and running Green Packet's Intouch allows users to roam
seamlessly between WiMAX and WiFi networks, thus creating a powerful
and highly desirable wireless broadband experience."

That seamless connectivity will soon be available to Malaysians.
Green Packet, with its headquarters in Kuala Lumpur, has already
signed up Malaysia's first and largest WiMAX operator, Packet One
Networks (Malaysia) Sdn Bhd (P1) to roll out this new and innovative
technology in the coming months.

GDM7215 implements mobile WiMAX RF/MAC/PHY and WiFi RF/MAC/PHY on
a monolithic integrated circuit. GDM7215 supports multimode wireless
connectivity with its on-chip RF transceivers, allowing seamless
broadband and local wireless roaming. Based on GCT's industry-proven
CMOS RF technology, GDM7215 integrates WiMAX and WiFi radios, a high
performance ARM9 RISC processor along with a 32-bit uniscalar DSP, and
a full range of advanced interfaces for network, storage, and
audio/visual device applications.

Green Packet Intouch debuts at CommunicAsia 2008, which runs from
June 17-20, at Singapore Expo. Green Packet Berhad's exhibition booth
is located in Hall 3, booth number 3E2-01.
