User's Manual Part 1

replace 802.11's RC4-based encryption under the 802.11i specification. AES, the
gold-standard encryption algorithm, provides maximum security for wireless network.
For user authentication, WPA adopts an authentication scheme through 802.1x. 802.1x
provides a framework for user authentication and a key distribution management method.
802.1x consists of three main elements: an Authentication Server (typically a RADIUS server),
WPA-enabled router or AP (called Authenticator), and a WPA-enabled client (called
Supplicant). 802.1x ensures only authorized users can access the network.
In enterprises, WPA will be used in conjunction with both a wireless router and authentication
server. In a Small Office/Home Office (SOHO) environment, where there is no authentication
server, users can use pre-shared key (PSK) mode in place of the authentication server.
The Dell Wireless 4350 Small Network Access Point offers both WPA running in PSK mode and
WPA with 802.1X authentication. The mutual authentication and improved encryption
technology of WPA allows wireless communication to achieve greater security.
Automatic Rate Selection and Rate Scaling
In 802.11g, wireless network adapters and access points can transmit data at one of the
following rates: 54, 48, 36, 24, 18, 12, 9, or 6 Mbps. In 802.11b, the data can be transmitted at
a rate of 11, 5.5, 2, or 1 Mbps. As the distance between an adapter and access point increases
or decreases, the data rate automatically changes. Other factors, like interference, also affect
the data rate. The Dell Wireless 4350 Small Network Access Point uses automatic rate
selection and rate scaling to determine the most efficient rate of communication. Rate scaling
maintains optimal communication between wireless clients and the WLAN.
