Broadcom Solutions Become Wi-Fi CERTIFIED for Wi-Fi Multimedia

9/10/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated silicon solutions enabling broadband communications, announced that its popular AirForceTM dual-band wireless LAN access point (the BCM94704AGR) and dual- band modifier client reference design (the BCM94309CB) are Wi-Fi CERTIFIEDTM for WMMTM (Wi-Fi Multimedia), ensuring interoperability with other products with WMM features. WMM provides advanced quality of service (QoS) features for Wi-Fi networks to improve the end-user experience by prioritizing audio, video and voice traffic and optimizing the way shared network resources are allocated among competing applications. Broadcom's reference designs are also part of the Wi-Fi Alliance WMM test environment used in the WMM certification process for other Wi-Fi® products.

Early WMM certification allows Broadcom to immediately support customers looking to include WMM features in products for next-generation Wi-Fi networks. Such products will use QoS capabilities to enhance the user experience for wireless multimedia applications, including Voice over Internet Protocol (VoIP), streaming video and music and Internet gaming.

"The quality of service capabilities inherent in WMM are pivotal for achieving industry-wide support for advanced multimedia features such as streaming video and music in Wi-Fi networks," said Stephen Palm Ph.D., Principal Engineer for Broadcom's Broadband Communications Group. "Broadcom's hardware partners can take advantage of our test bed participation and early WMM certification to build products that provide the interoperable QoS features that next generation Wi-Fi networks will require. WMM also makes a new realm of multimedia applications, such as VoIP, available for Wi-Fi equipment."

WMM provides QoS functionality for Wi-Fi multimedia applications by prioritizing traffic demands from different applications on the network. Prioritized traffic also ensures that each application receives the necessary network resources. In turn, QoS leads to a better end-user experience in a broad range of multimedia applications. VoIP and streaming video, in particular, greatly benefit from the WMM solution because they are extremely sensitive to the increased latency and decreased throughput that occur on a Wi-Fi network that does not support QoS functionality.

"Leading companies like Broadcom are committed to WMM as an industry-wide quality of service solution. Its commitment to interoperable multimedia support, along with many others in the industry, underscores the broad level of support for this QoS initiative," said Wi-Fi Alliance Managing Director, Frank Hanzlik.

WMM is especially important in the enterprise, where it plays a crucial role in supporting wireless VoIP, an application that utilizes the Wi-Fi network to deliver campus-wide wireless voice connectivity, providing significant cost savings over cellular voice options. WMM also includes prioritized traffic management features, which allow IT administrators to set priority policies to accommodate applications such as video streaming or teleconferencing.

"The creation of a standard for QoS, backed by compliance testing, is an important step toward ensuring enterprise customers that QoS-enabled Wi-Fi technology is mature enough for their networks," said Joseph Byrne, Principal Analyst of Gartner, Inc. "Mature standards for QoS, 54 Mbps link rates, and improved Wi-Fi security remove stumbling blocks to adopting Wi-Fi networks by enterprises and increase the quality of the end-user experience."

To experience the full benefit of the WMM specification, both the access point/router and the client device must support WMM, and the applications must include the appropriate WMM priority tags. Because some customers do not require QoS capabilities, devices that lack WMM functionality can coexist on a network running WMM, but their transmissions will continue to be sent on a best effort priority basis. Broadcom plans to offer a software upgrade to its current customers that require WMM support for legacy products.
