Glossary

LED

Light emitting diode used for monitoring a device or network condition.

Local Area Network (LAN)

A group of interconnected computer and support devices.

MAC Address

The physical layer address used to uniquely identify network nodes.

Power over Ethernet (PoE)

A specification for providing both power and data to low-power network devices using a single Category 5 Ethernet cable. PoE provides greater flexibility in the locating of access point’s and network devices, and significantly decreased installation costs.

RADIUS

A logon authentication protocol that uses software running on a central server to control access to the network.

RJ-45 Connector

A connector for twisted-pair wiring.

Roaming

A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the infrastructure network.

Service Set Identifier (SSID)

An identifier that is attached to packets sent over the wireless LAN and functions as a password for joining a particular radio cell; i.e., Basic Service Set (BSS).

Simple Network Management Protocol (SNMP)

The application protocol in the Internet suite of protocols which offers network management services.

Transmission Control Protocol/Internet Protocol (TCP/IP)

Protocol suite that includes TCP as the primary transport protocol, and IP as the network layer protocol.

UTP

Unshielded twisted-pair cable.

Virtual LAN (VLAN)

A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, and allows users to share information and resources as though located on the same LAN.
