Dynamic Host Configuration Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP), adding the capability of automatic allocation of reusable network addresses and additional configuration options.
Encryption
Data passing between the access point and clients can use encryption to protect from interception and eavesdropping.
Extended Service Set (ESS)
More than one wireless cell can be configured with the same Service Set Identifier to allow mobile users can roam between different cells with the Extended Service Set.
Extensible Authentication Protocol (EAP)
An authentication protocol used to authenticate network clients. EAP is combined with IEEE 802.1x port authentication and a RADIUS authentication server to provide “mutual authentication” between a client, the access point, and the a RADIUS server
Ethernet
A popular local area data communications network, which accepts transmission from computers and terminals.
File Transfer Protocol (FTP)
A TCP/IP protocol used for file transfer.
Hypertext Transfer Protocol (HTTP)
HTTP is a standard used to transmit and receive all data over the World Wide Web.
Internet Control Message Protocol (ICMP)
A network layer protocol that reports errors in processing IP packets. ICMP is also used by routers to feed back information about better routing choices.
IEEE 802.11b
A wireless standard that supports wireless communications in the 2.4 GHz band using Direct Sequence Spread Spectrum (DSSS). The standard provides for data rates of 1, 2, 5.5, and 11 Mbps.
IEEE 802.11g
A wireless standard that supports wireless communications in the 2.4 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The stan- dard provides for data rates of 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps. IEEE 802.11g is also backward compatible with IEEE 802.11b.
IEEE 802.1x
Port Authentication controls access to the switch ports by requiring users to first enter a user ID and password for authentication.
