WGU D413 TELECOMM AND WIRELESS COMMUNICATIONS
-VNO1 EXAM QUESTIONS AND CORRECT ANSWERS (NEW)
The available bandwidth is divided into frequency bands using frequency
division multiplexing (FDM), with each band being utilised for a distinct
communication channel.
FDM stands for frequency division multiplexing.
Television networks employ multiplexing to use analogue transmissions to
deliver local news material.
WDM stands for wavelength division multiplexing.
Different light wavelengths are used for channels in optical multiplexing.
WDM stands for wavelength division multiplexing.
Multiplexing is frequently utilised in computer networks and
telecommunications systems that transport light signals via fibre optic cables
using laser systems.
Digital signals are sent and received between connected devices using time-
division multiplexing (TDM).
TDM, or time-division multiplexing
Every user occasionally receives the full bandwidth for a brief burst of time; in
other words, the entire channel is devoted to a single user for a brief amount of
time.
, TDM, or time-division multiplexing
It is widely utilised in communications and computer communication.
By creating distinct slots, synchronous time-division multiplexing (STDM)
sends each signal from a single input source via a single time slot.
Time-division multiplexing that is synchronous (STDM)
set timeslots that are in sync with a clock.
Time-division multiplexing that is asynchronous (ATDM)
allots time slots to various data signals at random based on how quickly they are
produced from the source.
Each channel is given a distinct code by Code Division Multiplexing (CDM),
and all channels concurrently share the same frequency range. Digital
CDM, or code division multiplexing
Binary 1s and 0s are swapped out for longer, distinct binary sequences in this
multiplexing approach, which is widely employed by the military and cellular
phone companies to enable several customers to share a common range of
frequencies.
Spread spectrum technology and a unique coding scheme—in which each
transmitter is given a code—are used in Code Division Multiplexing (CDM).
Wireless devices that employ the 5-GHz radio band can use the Orthogonal
Frequency Division Multiplexing (OFDM) transmission technology, which can
reach data rates of up to 54 Mbps.
OFDM, or orthogonal frequency division multiplexing
Direct sequencing and frequency hopping are examples of multiplexing that
splits the allocated frequency into channels. electronic.
