Qualcomm Inc. has introduced a single-chip, high-performance 802.11n-compliant WLAN solution for handsets and mobile devices.

The WCN1312 supports data rates of up to 72Mbps—significantly higher than previous 802.11a, b, and g Wi-Fi solutions—for a better user experience while downloading data, watching streaming video or surfing the Internet.

The WCN1312 solution offers a high level of integration with a 2.4 GHz 802.11n base band processor, media-access controller, RF transceiver, transmit power amplifier, low-noise amplifier, transmit switch, power coupler and RF bandpass filter all in a small 7x7 mm package. This simplified design eliminates the need for many external RF components, minimising the component count and resulting in a smaller system footprint.

The new WCN1312 chip uses low-power 65nm CMOS technology and power-management techniques that minimise sleep, standby and active power consumption. It is optimised for performance with Qualcomm's complete Mobile Station Modem (MSM) solutions and supports a variety of mobile operating systems, including Qualcomm's Brew Mobile Platform, Android and Windows Mobile.

Qualcomm claims its new 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 optimise performance when paired with Qualcomm's Bluetooth solutions.

Scheduled for sampling in the second quarter, 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.
