GCT Semiconductor Intros WiMAX 2 4G Single-Chip

GCT Semiconductor, Inc has introduced new WiMAX 2 single-chip, GDM7225, integrating RF, MAC and PHY into a single-chip, with 4x4 Multiple Input Multiple Output (MIMO) system, making high-speed wireless broadband communications four to five times faster than existing WiMAX technology.

Users with the new integrated monolithic WiMAX 2 single-chip GDM7225 can easily avail higher data rates with backward compatibility with existing 16e mobile WiMAX (IEEE 802.16e) requirements.

The new GDM7225 also offers complete transceiver that backs total coverage of the 2GHz WiMAX band in Japan and other countries, and offers the world’s first 4x4 MIMO performance enabled by four independent RF receivers. The company has strategically collaborated with UQ Communications Inc. in Japan to enhance their 4G WiMAX network to the next level of performance.

“As the demand for wireless broadband continues to grow exponentially, UQ Communications Inc. is committed to advancing and improving our mobile WiMAX capacity in order to offer our users a superior experience,” said Akio Nozaka, President of UQ Communications Inc. “Our cooperation with GCT enables us to take full advantage of the potential of mobile WiMAX 2 in Japan.”

Also, the versatile GDM7225 utilises GCT’s proprietary MIMO modem technology to offer speeds of up to 150 Mbps downlink and 50 Mbps uplink, based on device specifications. It also supports multicarrier operation (10MHz + 10MHz) up to 20MHz bandwidth. With its advanced features and high data rate, GDM7225 is designed to serve the growing demands of the WiMAX broadband market.

“We believe WiMAX 2 is the natural next generation option for WiMAX operators to improve network performance cost-effectively and enhance the user-experience,” said Dr. Kyeongho “KH” Lee, President and CEO of GCT Semiconductor, Inc.

According to Lee their new WiMAX 2 single-chip will power the terminal devices needed by operators that are upgrading their networks and the announcement of GDM7225 today demonstrates their continuing efforts to advance the 4G ecosystem and provide market-proven 4G SoC solutions to their WiMAX and LTE customers.
