Hz
Hertz. The international unit for measuring frequency equivalent to the older unit
of cycles per second. One megahertz (MHz) is one million hertz. One gigahertz
(GHz) is one billion hertz. The standard US electrical power frequency is 60 Hz.
802.11a devices operate in the 5 GHz band; 802.11b and g devices operate in
the 2.4 GHz band.
I
IEEE
Institute of Electrical and Electronics Engineers, Inc. IEEE is a professional
organization with members in over 175 countries and is an authority in technical
areas such as computer engineering and telecommunications. IEEE developed
the 802.11 specifications.
IP Address
A 32-bit identification number for each node on an Internet Protocol network.
These addresses are represented as four sets of 8-bit numbers (numbers from 0
to 255), separated by periods ("dots").
Networks using the TCP/IP Protocol route messages based on the IP address of
the destination. Each number can be 0 to 255. For example, 192.168.0.100 could
be an IP address. Each node on the network must have a unique IP address.
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 in the ControlScape FH software 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.
