The physical layer address used to uniquely identify network nodes.
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.
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.
OFDM allows multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.
Repeater and bridge can provide an extended link to a remote access point
from the wired LAN. Access Point working in this mode could connect to
another AP in Access Point mode or Repeater and Bridge mode. Whenever
there are two APs having wireless link together (one in Access Point or
Repeater and Bridge mode, another using Repeater and Bridge mode), and
also have wired link separately, these two APs are also working as
.bridging. for the two wired links.
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).
Session keys are unique to each client, and are used to authenticate a
client connection, and correlate traffic passing between a specific client and
the access point.
A shared key can be used to authenticate each client attached to a wireless
network. Shared Key authentication must be used along with the 802.11
Wireless Equivalent Privacy algorithm.
SNTP allows a device to set its internal clock based on periodic updates
from a Network Time Protocol (NTP) server. Updates can be requested from
a specific NTP server, or can be received via broadcasts sent by NTP
servers.
