Emerging WLAN standards Three significant WLAN standards emerging that may offer significant benefits to enterprise business in the next 1 to 2 years are described in the following table. Table 5: HP recommended WLAN solutions Standard 802.11e 802.11i 802.11n Description Quality of Service. Enhances the current 802.11 MAC to expand support for applications with Quality of Service requirements, and in the capabilities and efficiency of the protocol. Examples of QoS applications include media streaming and Voice over IP. 802.11e will define managed classes of service for data, voice, and video applications. Enhanced Security. 802.11i includes all the security features of 802.1x and WPA plus AES. 802.11i is applicable to all the physical layer standards (802.11a, 802.11b, 802.11g); the associated WiFi interoperability test is called WPA2. Ratification Oct 04 June 2004 High Throughput WLAN. 802.11n specifies a new physical layer protocol for an 802.11 network with throughput up to 100 Mbps and modes compatible with 802.11g and 802.11a. late 2005 or early 2006 Benefit Improved performance for delay -sensitive applications like VoIP and streaming. very strong WLAN security. Note: Current HP WLAN Solutions will support 802.11i & WPA2 via a free software upgrade in 2H04. Higher throughput and network performance. Modes that are backward compatible with 802.11g and 802.11a. 11
