125 High Speed Mode (also known as SpeedBooster) is an end-to-end performance enhancement for 54g® products that provides up to 40 percent greater throughput than typical 802.11g systems. New products from several leading Wi-Fi equipment vendors feature this new "standards-plus" technology that improves real-world performance without impacting the performance of other wireless devices.

Independent test results from KeyLabs® found that access points and routers enabled with Broadcom's 125 High Speed Mode provide the best real-world wireless LAN performance in the industry. 125 High Speed Mode devices were shown to provide an average of 40% higher throughput than those using standard 802.11g, and offer up to 17% better performance than those based on the competing 108 technologies. Even in a network with mixed technologies, 54g outperforms other 802.11g solutions thanks to Xpress technology, which is built into all 54g products with 125 High Speed Mode.

* When operating in High Speed Mode, this Wi-Fi® device achieves an actual throughput of up to or greater than 34.1 Mbps, which is the equivalent throughput of a system following 802.11g protocol and operating at a signaling rate of 125 Mbps. Actual throughput will vary depending on environmental, operational and other parameters.
