Glossary
number of other EAP authentication methods can be used to perform client authentication. PEAP
requires a TLS certificate on the RADIUS server, but unlike EAP-TLS there is no requirement to
have a certificate on the client. PEAP has not been ratified by the IETF. The IETF is currently
comparing PEAP and TTLS (Tunneled TLS) to determine an authentication standard for 802.1X
authentication in 802.11 wireless systems. PEAP is an authentication type designed to take
advantage of server-side EAP-Transport Layer Security (EAP-TLS) and to support various
authentication methods, including user passwords and one-time passwords, and Generic Token
Cards.
Peer-to-Peer A wireless network structure that allows wireless clients to communicate directly with each other
mode without using an access point.
Power save The state in which the radio is periodically powered down to conserve power. When the portable
mode computer is in Power Save mode, received packets are stored in the access point until the
wireless adapter wakes up.
Preferred One of the networks that has been configured. Such networks are listed under Preferred
network networks on the Wireless Networks tab of the Wireless Network Connection Properties
(Windows* XP environment).
RADIUS RADIUS is an authentication and accounting system that verifies user's credentials and grants
(Remote access to requested resources.

RF (Radio The international unit for measuring frequency is Hertz (Hz), which is equivalent to the older
Frequency) unit of cycles per second. One MegaHertz (MHz) is one million Hertz. One GigaHertz (GHz) is
one billion Hertz. For reference: the standard US electrical power frequency is 60 Hz, the AM
broadcast radio frequency band is 0.55 -1.6 MHz, the FM broadcast radio frequency band is 88-
108 MHz, and microwave ovens typically operate at 2.45 GHz.
Roaming Movement of a wireless node between two micro cells. Roaming usually occurs in infrastructure
networks built around multiple access points. Current wireless network roaming is only
supported in the same subnet of a network.
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.
Shared key An encryption key known only to the receiver and sender of data. This is also referred to as a
pre-shared key.
SIM A SIM card is used to validate credentials with the network. A SIM card is a special smart card
(Subscriber used by GSM-based digital cellular networks.

Silent mode Silent Mode Access Points or Wireless Routers have been configured to not broadcast the SSID
for the wireless network. This makes it necessary to know the SSID in order to configure the
wireless profile to connect to the access point or wireless router.
Single Sign On Single Sign On feature set allows the 802.1X credentials to match your Windows log on user
name and password credentials for wireless network connections.
SSID (Service SSID or network name is a value that controls access to a wireless network. The SSID for your
Set Identifier) wireless network 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. Each SSID may be up
to 32 alphanumeric characters long and is case-sensitive.
stealth A stealth access point is one that has the capability and is configured to not broadcast its SSID.
This is the WiFi network name that appears when a DMU (Device Management Utility, such as
Intel® PROSet/Wireless WiFi Connection Utility) scans for available wireless networks. Although
this can enhance wireless network security, it is commonly considered a weak security feature.
To connect to a stealth access point, a user must specifically know the SSID and configure their
DMU accordingly. The feature is not a part of the 802.11 specification, and is known by differing
names by various vendors: closed mode, private network, SSID broadcasting.
TKIP (Temporal Temporal Key Integrity protocol improves data encryption. Wi-Fi Protected Access* uses its
Key Integrity TKIP. TKIP provides important data encryption enhancements including a re-keying method.
