IEEE 802.11g
A wireless standard that supports wireless communications in the 2.4 GHz band
using using Orthogonal Frequency Division Multiplexing (OFDM). The standard
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.
Infrastructure
An integrated wireless and wired LAN is called an infrastructure configuration.
Inter Access Point Protocol (IAPP)
A protocol that specifies the wireless signaling required to ensure the successful
handover of wireless clients roaming between different 802.11f-compliant access
points.
Local Area Network (LAN)
A group of interconnected computer and support devices.
MAC Address
The physical layer address used to uniquely identify network nodes.
Network Time Protocol (NTP)
NTP provides the mechanisms to synchronize time across the network. The time
servers operate in a hierarchical-master-slave configuration in order to synchronize
local clocks within the subnet and to national time standards via wire or radio.
Open System
A security option which broadcasts a beacon signal including the access point’s
configured SSID. Wireless clients can read the SSID from the beacon, and
automatically reset their SSID to allow immediate connection to the nearest access
point.
Orthogonal Frequency Division Multiplexing (ODFM)
OFDM/ allows multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.
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.
