Data Sheet Features And Benefits Table 1 lists the features and benefits of the Cisco Aironet 802.11a/b/g Wireless CardBus Adapter. Table 1. Product Features and Benefits Feature Cisco Secure Wireless Solution Enhanced Client Network Management Features EAP Single Sign-on Site Survey Utility Cisco Wireless Domain Services (WDS) Fast Secure Roaming Benefit IEEE 802.1X support, including Cisco LEAP, PEAP-GTC, PEAP-MSCHAPv2, EAP-FAST and EAP-TLS for mutual authentication with dynamic per-user, per-session encryption keys via TKIP enhancements. Full support for WPA and WPA2.. Full support for Management Frame Protection (MFP) Bundled with comprehensive, easy-to-use client network management utilities to provide a secure, intuitive, and convenient way to manage and configure the adapter. Convenient option to use login credentials for LEAP sign-on on the user's network, eliminating the need to enter a second set of credentials. The site survey utility can assist in conducting site surveys, as well as troubleshooting existing RF wireless LANs. The utility operates at the RF level and is used to determine the best placement and coverage (overlap) for the network's infrastructure devices. Cisco WDS is a collection of Cisco IOS® Software features that enhance wireless LAN client mobility and simplify wireless LAN deployment and management. Cisco WDS includes radio management aggregation, fast secure roaming, client tracking, and WAN link remote site survivability. Allows authenticated client devices to roam securely from one access point to another, within or across subnets, without any perceptible delay during reassociation. Provides support for latency-sensitive applications such as voice over IP (VoIP), enterprise resource planning (ERP), and Citrix.
