GCT`s Single-Chip Solution Enables the Portable WiMAX/WiFi Router to Further
Expand and Enhance Mobile WiMAX User Experience in Russia Through WiFi-Enabled
Devices
SAN JOSE, Calif.--(Business Wire)--
GCT Semiconductor, a leading supplier of Mobile WiMAX solutions to the global
market, today announced that the "Yota Egg," a portable WiMAX/WiFi router
launched by Yota, a Russian developer and provider of mobile services, is
powered by GCT`s Mobile WiMAX 2.5 GHz Wave 2 single-chip, GDM7205. The Yota Egg
is manufactured by Interbro, a leading Korean manufacturer, and is the first
router to allow users of WiFi-enabled devices such as notebooks, iPhones and
VoIP phones, to connect to a WiMAX network instantly, without the use of a WiMAX
USB Dongle or modem. Close collaboration between GCT, Interbro and Yota played a
key role in Yota`s launch of the Yota Egg in Russia on October 7.

GCT`s GDM7205 optimizes WiMAX implementation for Mobile WiMAX devices, ideally
supporting Yota`s launch of the Yota Egg in Russia. GCT`s compact solution
offers a highly integrated, low-power transceiver which minimizes the number of
external RF front-end components, therefore simplifying PCB design complexity.
Based on GCT`s industry-proven CMOS technology, this WiMAX Forum Certified
single-chip satisfies the high demands of multimedia data processing and
wireless connectivity, and increases battery life for the longest run time.

"The stylish and compact Yota Egg allows users to instantly connect via Wi-Fi to
our Yota Mobile WiMAX network which is available in Moscow, St. Petersburg and
Ufa," said Yota`s Sales Director Igor Torgov. "Working closely with GCT and
Interbro, we were able to develop this small high-performance router, which is
easy to use and carry, and includes a separate power source. The Yota Egg will
instantly create an online area wherever it's necessary; in the office or in a
classroom, in a car or outside in a park, anywhere, anytime."

"GCT`s expertise and proven Mobile WiMAX solutions allowed us to develop this
handy compact router with a long battery life of up to 6 hours," said Gyu Taek
Lee, CEO of Interbro. "We look forward to a continued relationship with GCT and
working together to develop innovative solutions for the WiMAX market and
further enable WiMAX deployments."

"The Yota Egg offers a truly unique solution for users with Wi-Fi enabled
devices, allowing them to connect instantly to a WiMAX network," commented Dr.
KH Lee, president and CEO of GCT Semiconductor. "We`re pleased to have been
selected by a prominent WiMAX service provider in Russia, Yota, and a leading
Korean manufacturer of WiMAX devices, Interbro, to contribute to their
successful launch of the Yota Egg."
