K
Key
A set of information (often 40 to as much as 256 bits) that is used as a seed to an
encryption algorithm to encrypt (scramble) data. Ideally, the key must also be
known by the receiver to decrypt the data.
L
LAN
A system of connecting PCs and other devices within the same physical
proximity for sharing resources such as internet connections, printers, files, and
drives. When Wi-Fi is used to connect the devices, the system is known as a
wireless LAN or WLAN.
LED
Light-emitting diode.
Line of Sight (LoS)
A clear line from one antenna to another in a long-range wireless network.
Link point
The graphical point next to a radio icon that represents the connection point for
RF communications between radios. An RF connection between two radios is
called an RF Link and is represented as a graphical black line between the
radio’s link points.
M
MAC ID
Media Access Control address. Every 802.11 device has its own MAC address.
This is a unique identifier used to provide security for wireless networks. When a
network uses a MAC table, only the 802.11 radios that have had their MAC
addresses added to the network’s MAC table are able to get on the network.
Master device
Device that is connected to the Master radio.
Mbps
Megabits per second, or millions of bits per second. A measure of bandwidth.
Megahertz
A measure of electromagnetic wave frequency equal to one million hertz. Often
abbreviated as MHz and used to specify the radio frequency used by wireless
devices.
