Qualcomm introduces industry's first dual-band 802.11n chip supporting 4x4 MIMO with peak data rates of 600 Mbps

(Based on Qualcomm's press release)

Qualcomm [introduces] the N-Stream™ Wireless LAN WCN1320™ chip, the industry's first dual-band 802.11n standards-based wireless local-area networking (WLAN ) solution with 4x4 multiple-input multiple-output (MIMO) technology. Offering industry-leading performance of 600 Mbps, the new chip is designed to enable users to distribute multiple simultaneous streams of high-definition video, voice and data throughout the home, without the hassle and cost of installing cables or the interference and range problems of previous wireless technologies.

The significance of this chip will be a reduction in the cost of implementing a 4-radio, 4x4 antenna solution for that data rate.
