GCT Semiconductor introduced a WiMAX 2 (IEEE 802.16m) single-chip solution that integrates RF, MAC and PHY. The monolithic WiMAX 2 single-chip offers a 4×4 Multiple Input Multiple Output (MIMO) system, enabling high-speed wireless broadband communications four to five times faster than existing WiMAX technology.
GCT said its new GDM7225 chip allows for higher data rates and provides backward compatibility with existing 16e mobile WiMAX (IEEE 802.16e) requirements. It features a complete transceiver that supports full coverage of the 2GHz WiMAX band in Japan and other countries, and offers the world’s first 4×4 MIMO performance enabled by four independent RF receivers. With GCT’s proprietary MIMO modem technology, GDM7225 enables performance at speeds of up to 150 Mbps downlink and 50 Mbps uplink, based on device specifications. In addition, GDM7225 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. “Our new WiMAX 2 single-chip will power the terminal devices needed by operators that are upgrading their networks. The announcement of GDM7225 today demonstrates our continuing efforts to advance the 4G ecosystem and provide market-proven 4G SoC solutions to our WiMAX and LTE customers.” http://www.gctsemi.com
