This parameter should be left at the “Normal” setting, unless there is a specific need to
use the interface for spectrum analysis. Note that setting this parameter to Basic Spectrum
Analyzer disables all access point functionality previously running on that interface.
8.0 Glossary
802.11:
802.11 is a family of specifications for Wireless Local Area Networks
(WLANs) developed by a working group of the Institute of Electrical and
Electronics Engineers (IEEE). The original specification provides for an Ethernet
Media Access Controller (MAC) and several physical layer (PHY) options, the
most popular of which uses GFSK modulation at 2.4GHz, enabling data rates of 1
or 2Mbps. Since its inception, two major PHY enhancements have been adopted
and become “industry standards”. 802.11b adds CCK modulation enabling data
rates of up to 11Mbps, and 802.11a specifies OFDM modulation in frequency
bands in the 5 to 6GHz range, and enables data rates up to 54Mbps.
AICS
: Automatic Intelligent Channel Selection is the capability for the Access
Point to select best channel based on the RF environment conditions.
ATPC:
Automatic Transmit Power Control is the capability for the Access Point to
select best transmit power based on the RF environment conditions.
Authentication:
The process of establishing the identity of another unit (client,
user, device) prior to exchanging sensitive information.
Bluetooth:
An open specification for short-range wireless voice and data
communication. Bluetooth is a trademark owned by Telefonaktibolaget L M
Ericsson, Sweden, and licensed to promoters and adopters of the Bluetooth Special
Interest Group (SIG).
DFS:
Dynamic frequency selection refers to the radar avoidance algorithm
referred by 802.11h amendment.
DHCP:
Dynamic Host Configuration Protocol (DHCP) is a communications
protocol that lets network administrators centrally manage and automate the
assignment of Internet Protocol (IP) addresses in an organization's network. Using
the Internet Protocol, each machine that can connect to the Internet needs a unique
IP address. When an organization sets up its computer users with a connection to
the Internet, an IP address must be assigned to each machine. Without DHCP, the
IP address must be entered manually at each computer and, if the computer moves
to another location in another part of the network, a new IP address must be
entered. DHCP lets a network administrator supervise and distribute IP addresses
from a central point and automatically sends a new IP address when a computer is
plugged into a different place in the network.
DNS:
Domain Name Service. An Internet service that translates a domain name
such as example-systems.com to an IP address, in the form xx.xx.xx.xx, where xx
is an 8 bit hex number.
