GCT Semiconductor Honored with 27th Radiowave
Achievement Award from Minister of Internal Affairs and
Communications for 4X4 MIMO Deployment in Japan

San Jose, CA– June 29, 2016 – GCT® Semiconductor, a leading designer and supplier of advanced 4G mobile semiconductor solutions, was recently recognized by the Japanese Minister for Internal Affairs and Communications for its efforts in deploying the world’s first 4X4 MIMO service throughout Japan. GCT’s Co-Founder and Board Member Kyeongho “KH” Lee received an Achievement Award at a ceremony on June 27 in Tokyo, along with several partner companies that made up the 4X4 MIMO development team, including UQ Communications Inc., Samsung Electronics Japan, Ericsson Japan K.K. and NEC Platforms, Ltd.

“It is an honor for GCT to receive this award and be recognized among such leaders in our industry,” says John Schlaefer, CEO of GCT Semiconductor, Inc. “We worked closely with UQ Communications to develop the chipset and enable 4X4 MIMO performance in broadband mobile wireless service across Japan.” With its partners, GCT supported UQ Communications with their need for higher speed and larger data capacity by enhancing frequency usage efficiency. The development team’s close collaboration enabled the 220Mbps “double speed” service that was launched in Japan in early 2015.

GCT’s GDM7243Q is the world’s first LTE-Advanced chip to offer high performance 4X4 MIMO technology, which improves LTE coverage, peak throughput and spectral efficiency.
