Next-generation Wi-Fi chipset gathers momentum
Broadcom Corporation reports that its Intensi-fi family of draft-802.11n silicon devices is gaining momentum as more manufacturers and consumers adopt next generation Wi-Fi technology.
"Consumers no longer have to settle for proprietary products which lock them into solutions from a single manufacturer".
"Consumers can now mix and match products from any one of the leading brands to implement high-performance Wi-Fi networks", said Michael Hurlston, Vice President and General Manager of Broadcom's Home and Wireless Business Unit.
"Broadcom is committed to creating a large ecosystem of standards-compliant products that provide a flawless multimedia experience".

Wi-Fi technology handles voice, video and data
Wireless routers with simultaneous dual-band functionality allow Wi-Fi users to maximise performance for multimedia applications, while remaining compatible with existing wireless devices.
Broadcom's Intensi-fi chipsets are the premier implementation of the draft-802.11n specification.
They combine best-in-class radio and digital technologies to deliver superior wireless performance and reliable connectivity throughout a home or office.
With real world throughput of greater than 180Mbit/s, products built with Intensi-fi solutions enable consumers and businesses to take advantage of emerging voice, video and music applications on their wireless networks.
As a result, Intensi-fi technology is expected to extend beyond PCs and networking equipment into a variety of consumer devices, including Wi-Fi phones, storage drives, set-top boxes, broadband modems, TV and stereo equipment, gaming systems, and digital cameras.
Intensi-fi solutions provide reliable wireless connections, particularly in challenging environments.
To maintain high performance, Intensi-fi uses Active Diversity, an intelligent signal processing technique, and best-in-class receive sensitivity to further enhance coverage area.
Intensi-fi technology complies with the current IEEE802.11n draft specification and is designed to be upgradable to meet the final IEEE802.11n specification.
Adherence to industry standards is a priority for Broadcom because it eliminates the compatibility and performance issues that plague users of proprietary products.
Intensi-fi technology has already been proven to interoperate at all link rates with other draft-802.11n implementations, and Broadcom will continue working with other industry leaders to demonstrate interoperability among brands of next generation Wi-Fi products.
A copy of the white paper: "802.11n: next-generation wireless LAN technology" is available for download on the Broadcom website.
Intensi-fi products are not only interoperable with a wide variety of 802.11a/b/g and draft-802.11n devices, but feature unique enhancements that actually improve the performance of legacy Wi-Fi products.
This maximises customers' investments and protects their existing equipment from immediate obsolescence.
Intensi-fi routers employ a "good neighbour" mode that ensures optimal performance in mixed networks when using the optional 40MHz transmission mode - dynamically managing the use of 40MHz channels and reverting back to 20MHz channels when traffic is high or legacy clients need to communicate.
The complete Intensi-fi solution includes a draft-802.11n media access controller (MAC)/baseband chip (BCM4321) and a finely-tuned, dual-band radio chip (BCM2055) that can be configured for a variety of high-speed wireless applications.
Broadcom also offers a high-performance network processor (BCM4704) that provides advanced routing and bridging capabilities for router and gateway designs.
The flexible Intensi-fi architecture allows manufacturers to balance performance and cost for next-generation designs.
Its all-CMOS design not only enables highly integrated and highly efficient chipsets, but also facilitates cost effective, high volume manufacturing.
By supporting multiple antenna configurations (2x2, 2x3, 3x3 and 4x4), Intensi-fi can be used in a variety of devices with different performance expectations and price points.
Intensi-fi solutions leverage Broadcom's proven OneDriver software, which provides for a consistent set of features that deliver superior performance, ease-of-use and security enhancements - including SecureEasySetup, 125 High Speed Mode, Wi-Fi Multimedia (WMM) and Wi-Fi Protected Access (WPA2).
