MIMO
Multiple Input Multiple Output refers to using multiple antennas in a WiFi device
to improve performance and throughput. MIMO technology takes advantage of a
characteristic called multipath, which occurs when a radio transmission starts out
at Point A and the reflects off or passes through surfaces or objects before
arriving, via multiple paths, at Point B. MIMO technology uses multiple antennas
to collect and organize signals arriving via these paths.
Multicast
In the CIP producer/consumer model, one producer multicasts (broadcasts) the
data once to all the consumers.
N
Network
A series of stations or nodes connected by some type of communication medium.
A network may consist of a single link or multiple links.
Node
An address or software location on the network.
P
Panel Antenna
An antenna type that radiates in only a specific direction. Panel antennas are
commonly used for point-to-point situations. Sometimes called Patch antennas.
Parabolic Antenna
An antenna type that radiates a very narrow beam in a specific direction.
Parabolic antennas offer the highest gain for long-range point-to-point situations.
Poll
A method of electronic communication.
Power Supply
Device that supplies electrical power to the I/O chassis containing the processor,
coprocessor, or other modules.
Producer
The source of information in the CIP networking model. See CIP.
Protocol
The language or packaging of information that is transmitted between nodes on a
network.
