Glossary
For unfamiliar terms used below, look for entries elsewhere in the glossary.
AD-HOC (IBSS)
Ad-hoc mode does not require an AP or a wired network. Network that transmits wireless from computer to computer without the use of a base station (access point).
Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS).
CHANNEL
A radio frequency used by a wireless device is called a channel.
EAP AUTHENTICATION
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE802.1X transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication.
ENCRYPTION
The reversible transformation of data from the original to a difficult-to-interpret format. Encryption is a mechanism for protecting confidentiality, integrity, and authenticity of data. It uses an encryption algorithm and one or more encryption keys.
FRAGMENTATION THRESHOLD
This is the maximum data fragment size that can be sent before the packet is fragmented into smaller packets.
IEEE 802.1X
The IEEE 802.1X standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server.
INFRASTRUCTURE (BSS)
When a number of wireless stations are connected using a single AP, you have a Basic Service Set (BSS).
27
RO A M I N G
In an infrastructure network, wireless stations are able to switch from one BSS to another as they move between the coverage areas. During this period, the wireless stations maintain uninterrupted connection to the network. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate AP depending on the signal strength, network utilization among other factors.
SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network. Wireless devices must have the same SSID to communicate with each other.
TEMPORAL KEY INTEGRITY PROTOCOL (TKIP)
Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server.
USER AUTHENTICATION
WPA applies IEEE 802.1X and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If you do not have an external RADIUS server, use WPA-PSK/WPA2-PSK (WPA -Pre-Shared Key) that only requires a single (identi­cal) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, clients will be granted access to a WLAN.
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the T EW -642EC and the AP or other wireless stations to keep network communications pri­vate. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.
WPA/WPA2
Wi-Fi Protected Access (WPA) and WPA2 (future upgrade) is a subset of the IEEE 802.11 i security specification draft. Key differences between WPA and WEP are user authentication and improved data encryption. WPA2 is a wireless security standard that defines stronger encryption, authentication and key management than WPA.
