promotes standards within the electronics and computer industries.
Interference
In wireless networking, the disturbance that results when radio signals from different APs
collide in the airwave.
IP (Internet Protocol) address
A 32-bit unique string of numerical characters used to identify a networked computer, printer,
or any other device.
LAN (Local Area Network)
A short-distance network that joins a group of computers together, usually within the same
building. Using a network hub as a wiring point, data can be sent from one computer to
another over the network.
Last Frame Time
The time when the last frame was detected being transmitted from a device in the wireless
environment.
MAC (Media Access Control) address
A unique, 48-bit number assigned to each IP network adapter. It is written in a sequence of 12
hexadecimal digits (e.g.,
46:2F:0B:19:11:CB). Each MAC address is uniquely set by the
network device manufacturer and is sometimes called the device’s “physical addresses”. The
first six hexadecimal digits of an MAC address correspond to a manufacturer's unique
identifier, while the last six digits correspond to the device's serial number.
Marker Type
A settings in the Real-Time FFT graph that becomes available once the Enable Marker is
selected in the Market Settings. There are two options for Maker Type: Single vs. Delta.
Makers are used to identify the data point or points of interest in the Real-Time FFT and
provides brief information about them.
Marker Settings
Maker Settings refer to the parameters used in the configuration of the Real-Time FFT graph.
See Marker Type and Spectrum Type.
Maximum Percentage
A parameter used in the configuration of the Spectrum Density graph. It can any value greater
than the Minimum Percentage but equal to or less than 100. See Minimum Percentage.
Media
Refers to the 802.11 protocol or protocols, which include 802.11a, b, g, and n, used by wireless
network or device.
Minimum Percentage
A parameter used in the configuration of the Spectrum Density graph. It can any value less
than the Minimum Percentage but equal to or greater than 0. See Maximum Percentage.
