preferred network A network connection profile created using Windows WZC. Such profiles are listed
under Preferred Networks on the Wireless Networks tab in Windows Wireless
Network Connection Properties.
provisioning Providing a peer with a trust anchor, shared secret, or other appropriate
information necessary for establishing a security association.
Q
QAM quadrature amplitude modulation A modulation technique that uses variations
in signal amplitude and phase to represent data-encoded symbols as a number of
states.
QoS Quality of Service (QoS) refers to the capability of a network to provide better
service to selected network traffic over various technologies. See
IEEE 802.11e.
R
radio stream A value that represents a spatial stream (X) and antenna (Y) configuration for an
IEEE 802.11n network connection. For example, a radio stream value of 3 × 3
represents 3 spatial streams using 3 antennas.
RADIUS Remote Access Dial-In User Service
residential gateway A stand-alone wireless hub that allows any computer that has a wireless network
adapter to communicate with another computer and to connect to the Internet. A
residential gateway is also referred to as an access point (AP).
RF radio frequency
roaming A feature of the Dell Wireless WLAN Card that enables
wireless clients to move
through a facility while maintaining an unbroken connection to the wireless
network.
root certificate Internet Explorer divides certification authorities (CAs) into two categories, root
certification authorities and intermediate certification authorities. Root certificates
are self-signed, meaning that the subject of the certificate is also the signer of the
certificate. Root CAs have the ability to assign certificates for intermediate CAs. An
intermediate CA has the ability to issue server certificates, personal certificates,
publisher certificates, or certificates for other intermediate CAs.
RTS threshold The number of frames in the data packet at or above which an RTS/CTS (request to
send/clear to send) handshake is turned on before the packet is sent. The default
value is 2347.
S
scanning An active process in which the Dell Wireless WLAN Card sends Probe-Request
frames on all channels of the ISM frequency range and listens for the Probe-
Response frames sent by
wireless routers/APs and other wireless clients.
single sign-on A process that allows a user with a domain account to log on to a network once,
using a password or smart card, and to gain access to any computer in the domain.
smart card Smart cards are small portable credit-card shaped devices with internal integrated
circuits (ICs). The combination of the small size and IC make them valuable tools
for security, data storage, and special applications. The use of smart cards can
improve user security by combining something a user has (the smart card) with
something only the user should know (a PIN) to provide two-factor security that is
more secure than passwords alone.
SSID service set identifier A value that controls access to a wireless network. The
SSID for your Dell Wireless WLAN Card must match the SSID for any access point
that you want to connect with. If the value does not match, you are not granted
access to the network. You can have up to three SSIDs. Each SSID can be up to
32 characters long and is case-sensitive. Also referred to as the network name.
STA station A computer that is equipped with a wireless LAN network adapter (see also
wireless client). A station can be stationary or mobile.
Signal Strength Signal strength refers to the magnitude of the signal at a reference point that is a
significant distance from the transmitting antenna.
In Windows XP, signal strength of access points can be viewed at Control panel-
