Glossary-12
Multi-path fading
The condition in which the “true” signal from an antenna reflects off an object (usually the ground) and, as a result, the
reflected signal causes destructive interference at the receiving antenna. Multi-path fading affects linearly polarized sig-
nals more than circularly polarized signals.
Network
A set of connections that allow them to exchange data with each other, which enables multiple users to share to communi-
cate data through the accepted path(s).
Network
Two or more locations tied together with equipment and communications channels.
Node
This is a point on the network such as a computer, server, peripheral (printer, scanner, etc).
Noise
Any unwanted signal or disturbance that degrades the quality of a transmitted signal.
Obstruction
Any man-made or natural object that blocks, diffracts, or reflects a transmitted signal.
Octet
There are four octets in an IP address. Each octet contains 8 bits, which are equivalent to 1 byte. Each octet is separated
by a period (.).
OD
Outside diameter of pipe for mounting an antenna.
Outdoor Unit
The Outdoor Unit (ODU) provides the baseband and RF signal processing required to convert the 100Base-T signal from
the CPI to an RF frequency at 23, 26, 29, or 38 GHz. The ODU mounts to an antenna through an integral “Quick-Fit”
connection that does not require any external waveguide. The ODU housing is ruggedized to protect the RF and modem
electronics contained inside. It is capable of simultaneously transmitting and receiving 100 Mbps of data traffic over the
air.
Packet
A unit of data transmitted between a receiver and a sender. Each packet contains embedded information, as well as place
to go on the network (known from the IP address).
