Qualcomm Inc. has released the WCN1312 single-chip, high-performance 802.11n-compliant WLAN solution for handsets and mobile devices. This highly integrated device supports data rates of up to 72Mbit/ssignificantly higher than previous 802.11a, b, and g Wi-Fi solutionsfor a better user experience while downloading data, watching streaming video or surfing the Internet.

"As demand increases for WLAN connectivity in handsets and other mobile devices, carriers are migrating to higher-performance, more integrated solutions," said Mike Concannon, senior VP of connectivity and wireless modules for Qualcomm CDMA Technologies. "The new WCN1312 solution gives our customers an extremely compact 802.11n solution with leading-edge performance and full system-level integration with other Qualcomm chipsets, which minimizes design time and reduces manufacturers' time-to-market."

The WCN1312 solution offers a high level of integration with a 2.4GHz 802.11n baseband processor, media-access controller, RF transceiver, transmit power amplifier, low-noise amplifier, transmit switch, power coupler and RF bandpass filter all in a small 7mm x 7mm package. This simplified design eliminates the need for many external RF components, minimizing the component count and resulting in a smaller system footprint.

The new WCN1312 chip uses low-power 65nm CMOS technology and advanced power-management techniques to minimize sleep, standby and active power consumption. It is optimized for performance with Qualcomm's complete Mobile Station Modem solutions and supports a variety of mobile operating systems, including Qualcomm's Brew Mobile Platform, Android and Windows Mobile. The WCN1312 chip is the industry's first mobile handset device to support both 1x1 and 1x2 dual-receive configurations to increase range and data throughput performance when needed. The WCN1312 solution also implements advanced coexistence architecture and algorithms to optimize performance when paired with Qualcomm's Bluetooth solutions.

Scheduled for sampling in Q2, the WCN1312 chip is expected to be in volume production by the fourth quarter of 2009, and is part of a complete end-to-end solution for 802.11n from Qualcomm, which also includes the WCN1320 solution for consumer electronic devices.
