Experience
SINGAPORE--(Business Wire)--
GCT Semiconductor, a leading supplier of mobile WiMAX solutions to the global
market, and Green Packet, a leading developer of next generation mobile
broadband and networking solutions, today announced a strategic collaboration
combining the expertise of both companies to develop a truly seamless solution
for wireless devices to roam between WiFi and WiMAX networks.

The solution includes GCT`s GDM7215, the industry`s first single-chip supporting
both mobile WiMAX IEEE 802.16e Wave 2 and WiFi 802.11 b/g, and Green Packet`s
Intouch Connection Manager (CM) software. Green Packet`s software combines
intelligent connection management, seamless connectivity between different
network environments, and lifestyle value added services into a single client.

The collaboration offers a powerful combined solution allowing end-users to roam
seamlessly between WiFi and WiMAX. This combined solution is ideally suited for
mobile portable devices including netbooks, smartphones, mobile Internet devices
(MIDs), etc.

Green Packet and GCT are showcasing their solution at the WiMAX Forum Congress
Asia (WFCA) in Singapore on April 28 and 29, at booth 83. GCT is also a sponsor
of the Live WiMAX Network Tour (LWNT) held in conjunction with WFCA. The LWNT
will provide attendees with the opportunity to enjoy Packet One (P1) live WiMAX
connectivity on the move in a real-life metropolitan environment in Johor Bahru,
Malaysia. The collaborative effort of GCT and GP will offer attendees the
experience of seamless mobility between WiFi and WiMAX, which promises
uninterrupted connectivity while on the go.

Dr. Kyeongho Lee, President and CEO of GCT Semiconductor, said, "GCT and Green
Packet are working closely together to offer a combined solution that supports
WiFi and WiMAX connectivity on a single-chip. We`re very pleased to be combining
our expertise to further advance the development of WiMAX technologies and
complement WiMAX and WiFi networks."

Kelvin Lee, Senior General Manager of Green Packet Berhad, said, "Mobile
broadband is no longer just an idea on paper or a vision for the future. Being
always connected is now a reality. With Green Packet`s Intouch CM, 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."

GCT and Green Packet have a long relationship of working together to deliver
solutions to the WiMAX market. P1, a subsidiary of Green Packet, recently
launched `Wiggy`, a WiMAX dongle enabled by GCT`s GDM7205. GCT`s GDM7205 is the
industry`s first mobile WiMAX 2.3GHz single chip solution, including RF, MAC and
PHY all into one monolithic integrated circuit.
