LAN (Local Area Network)
A network configured from mutual connections between computers
within a limited area. Also called an "intranet" or "business or
regional data communications network."
RSSI (Receive Signal Strength Indication)
A numeric indicator of incoming signal strength.
Spectrum diffusion transmission
A method of transmission in which signals that are normally
transmitted over a given limited frequency band undergo narrow
band modulation (primary modulation), then again diffuse
modulation (secondary modulation) to intentionally diffuse the
signal over a broad frequency spectrum.
DS (Direct Sequence)
A type of spectrum diffusion signal using narrow band modulation
with phase modulation, in which the diffusion is by means of phase
modulation using a broad band diffusion signal (pseudo random
strings).
CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance)
CSMA is a method of avoiding collision by which wireless
terminals listen before transmitting and do not transmit if they can
year transmissions from other wireless terminals. CSMA/CA is
CSMA plus additional collision avoidance functions.
Hidden Terminal Problem
When wireless terminals are farther apart then their electric signals
can reach, or their signals are obstructed by objects, neither may be
able to receive the other's signals. Any two such wireless
terminals are said to be hidden from each other. In Ad Hoc mode,
because the carrier sense function is not effective between hidden
terminals there is a higher probability of collisions and throughput
(the volume of information sent in a given time interval) is reduced.
