User's Manual

802.11g
The 802.11g standard specifies a maximum data transfer rate of 54
Mbps, an operating frequency of 2.4GHz, and WEP encryption for
security. 802.11g networks are also referred to as Wi-Fi* networks.
802.11n
A task group of the IEEE 802.11 committee has defined a new draft
specification that provides for increased throughput speeds of up to
540 Mbps. The specification provides for Multiple-Input-Multiple-
Output (MIMO) technology, or using multiple receivers and multiple
transmitters in both the client and access point, to achieve improved
performance. The specification is expected to be approved in the late
2008 timeframe.
802.1X
802.1X is the IEEE Standard for Port-Based Network Access Control.
This is used in conjunction with EAP methods to provide access
control to wired and wireless networks.
AAA Server
Authentication, Authorization and Accounting Server. A system to
control access to computer resources and track user activity.
Access Point (AP)
A device that connects wireless devices to another network. For
example, a wireless LAN, Internet modem or others.
Ad Hoc Network
A communication configuration in which every computer has the
same capabilities, and any computer can initiate a communication
session. Also known as a peer-to-peer network, a device to device
network or a computer-to-computer network.
AES-CCMP
Advanced Encryption Standard - Counter CBC-MAC Protocol is the
new method for privacy protection of wireless transmissions specified
in the IEEE 802.11i standard. AES-CCMP provides a stronger
encryption method than TKIP. The AES algorithm is capable of using
cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt
data in 128-bit blocks. AES-CCMP uses the AES block cipher, but
restricts the key length to 128 bits. AES-CCMP incorporates two
sophisticated cryptographic techniques (counter mode and CBC-
MAC) to provide improved security between the mobile client and the
access point.
Authentication
Verifies the identity of a user logging onto a network. Passwords,
digital certificates, smart cards and biometrics are used to prove the
identity of the client to the network. Passwords and digital
certificates are also used to identify the network to the client.
Available network
One of the networks listed under Available networks on the Wireless
Networks tab of the Wireless Network Connection Properties
(Windows* XP environment). Any wireless network that is
broadcasting and is within receiving range of the WiFi adapter
appears on the list.
BER
Bit Error Rate. The ratio of errors to the total number of bits being
sent in a data transmission from one location to another.
Bit Rate
The total number of bits (ones and zeros) per second that a network
connection can support. Note that this bit rate will vary, under
software control, with different signal path conditions.
Broadcast SSID
Used to allow an access point to respond to clients on a wireless
network by sending probes.
BSSID
A unique identifier for each wireless client on a wireless network. The
