Qualcomm Enables Whole-House Media Streaming with Industry's First 4x4 MIMO Wireless Network Solution
|05 июня 2009|
Qualcomm introduced 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.
Qualcomm's N-Stream WLAN solution is being demonstrated this week at Computex Taipei and at Connections 2009 in Santa Clara.
“Qualcomm's advanced 4x4 MIMO technology sets a new performance milestone for home media streaming devices,” said Mike Concannon, senior vice president of Connectivity and Wireless Modules for Qualcomm CDMA Technologies. “Our N-Stream solution delivers a new level of performance and range, enabling next-generation whole-house wireless LAN coverage.”
Qualcomm has created WLAN reference module designs to enable manufacturers to quickly integrate WCN1320 into a wide range of media streaming consumer electronic devices such as access points, set-top boxes, and media-centric devices. The WCN1320 chip includes an internal high-speed application processor to run the WLAN software within the chip which provides OEMs the flexibility to use lower cost host processors in their design, easing integration, and reducing development costs for adding WLAN to their products.
“Qualcomm's WCN1320 chip opens up new possibilities for the digital home, and we have been collaborating closely to bring this technology to market, paired with our set-top box solutions,” said Mark Samuel, general manager Cable and IP STB business, NXP Semiconductors. “We are very excited about the progress we have made in jointly enabling a new level of whole-house wireless media streaming coverage with exceptionally high bandwidth for multiple media streams.”
“AppliedMicro, a global leader in energy conscious computing and communications solutions for enterprise applications, is pleased to work with Qualcomm to complement our multimedia networking expertise with this new WLAN technology,” said Gopi Sirineni, AppliedMicro's vice president of consumer and SMB business. “The combination of Qualcomm's WCN1320 WLAN and AppliedMicro's Power Architecture embedded processor technology in access points, NAS, and gateways enables end-to-end solutions that accelerate the deployment of wireless media streaming for both consumer and enterprise applications.”
WCN1320's advanced 4x4 MIMO technology uses four spatial streams to distribute multiple streams of concurrent voice, video and data in either the 5GHz or 2.4 GHz radio bands. Qualcomm has developed sophisticated algorithms which take advantage of the multiple transmitters and receivers to increase data throughput, extend range and overcome interference with a spectrally efficient solution. Qualcomm's WCN1320 solution is backward compatible with existing 802.11a, b, and g devices.
The highly integrated N-Stream WCN1320 solution utilizes a 65-nanometer CMOS process technology to combine an embedded applications processor, media-access controller, digital baseband, radio-frequency transceiver and system power-management in a single compact 12x12 mm package.
Qualcomm's N-Stream WLAN WCN1320 solution is expected to begin sampling in the second quarter of 2009. The WCN1320 is part of a complete end-to-end solution for 802.11n from Qualcomm, which also includes the WCN1312™ solution for handsets and other mobile devices.
