Broadcom Corporation announced it is shipping technology that enables 54g wireless LAN products to deliver the industry's best real-world performance. Afterburner technology is an enhancement for the 54g platform, Broadcom's maximum performance implementation of the IEEE 802.11g standard. Products with this new technology provide up to 40 percent greater throughput than typical standard 802.11g systems without impacting the performance of neighboring wireless LANs.
New products from several leading wireless LAN vendors will feature this new "standards-plus" technology that enhances the existing 802.11g standard without causing interference to other wireless devices. Linksys has incorporated the technology into its new family of SpeedBooster products, while Belkin, Buffalo and others will promote the technology as "125 High Speed Mode". These products will enable residential customers to use wireless networks for bandwidth-intensive applications, such as sharing digital photos and transferring audio and video files between devices throughout the home.
Wireless LAN solutions enhanced with Afterburner technology can achieve optimal speeds when all network devices include the new technology. However, since real-world wireless networks may include a mix of brands, Broadcom has engineered the technology to remain compatible with all 802.11b/g Wi-Fi devices, while providing a significant aggregate performance enhancement for all Wi-Fi devices on the network. Because Afterburner technology employs standards-friendly techniques to increase the efficiency of wireless transmissions, adding enhanced products actually benefits the entire Wi-Fi ecosystem.
Tests performed by KeyLabs have shown that products with Afterburner technology provide industry-leading performance in a real-world environment of any solution available in the market. In addition to increasing the throughput of devices in high-speed mode, Broadcom's technology improves the overall performance of networks that include products that are not based upon Broadcom silicon.
Additional Throughput without Causing Interference
Afterburner technology is a "good neighbor" enhancement that boosts wireless throughput without the interference effects of current alternative technologies that promise 108 Mbps performance. Derived from standards-based frame bursting techniques, Broadcom's high-speed technology improves network efficiency while remaining compliant with the 802.11g channel requirements limiting transmissions to a single wireless channel. By contrast, "108" products violate the standard's channel requirements and occupy all usable channels in the 2.4 GHz band, thus causing significant interference to neighboring Wi-Fi networks and other wireless devices in the band, such as cordless phones. Third-party tests conducted by The Tolly Group have confirmed that "108" is ""bad neighbor" technology, creating severe interference to neighboring Wi-Fi devices.
Products with Broadcom's high-speed solution adhere to IEEE frequency channel rules and scale for use in offices and homes that use more than one access point. Competing channel bonding solutions suffer performance degradation for each additional new access point. Unlike competing standards-plus solutions, Broadcom's Afterburner technology is expected to ship in a wide variety of Wi-Fi enabled platforms, including routers, access points, client cards, notebook PCs and broadband modems.
54g is Broadcom's implementation of the IEEE 802.11g standard, the mainstream Wi-Fi technology for homes, businesses and public hot spots. 54g technology provides the industry's best combination of speed, reach and security, and is compatible with the 70 million 802.11g and 802.11b devices installed to date. 54g technology can be found in the leading brands of wireless LAN products, including Apple, Belkin, Buffalo, Cisco/Linksys, Dell, eMachines, Fujitsu, Gateway, HP/Compaq, Microsoft and Motorola. At the end of December 2003, Broadcom 54g comprised 77 percent of the 802.11g network gear sold through U.S. retail, according to NPD Techworld, a division of The NPD Group.
