BTEC Unit 10 - Communication Technologies: Transmission Presentation

This presentation, created for a BTEC Unit 10 assignment, explores various communication technologies and their associated transmission methods. It begins by differentiating between guided and unguided media, then delves into specific transmission techniques such as coaxial cables, optical fiber, microwave, and satellite systems. The presentation examines the criteria for selecting appropriate methods, considering factors like bulkiness, cost, and security. It then compares the effectiveness of different methods, outlining their features, applications, and limitations. The content includes detailed specifications for each transmission type, including elements of optical fiber, microwave frequencies, and satellite transmission components. The presentation also addresses obstacles to data transmission and highlights the importance of understanding each method's specifications for effective application.

M2: Explain why particular transmission methods are chosen in particular
situations
Transmission
methods
There are different
types of transmission
methods which are
extensively used in
both business
organizations as well
as in our society.

Introduction
There are two types
of transmission media
which are discussed
below:
• Unguided
• Guided There are two types
of guided media
which are discussed
below:
• Unshielded twisted

M2: Explain why particular transmission methods are chosen
in particular situations
The foremost determination of the
presentation is to focus on choosing a
particular method in particular
situations (Neves et al. 2018). Each of
the different types of transmission
techniques such as Coaxial, optical
fiber, shield twisted pair, infrared,
radio, microwave, satellite unshielded

Criteria for choosing
Transmission methods
Bulkiness has to be
considered before
selecting the
transmission
technique (Neves et
al. 2018). The cost of
each transmission
technique has to be
also considered.
Security of the

Coaxial Transmission method
The coaxial
transmission
method are
generally used for
the transmission of
the radio
frequency signals
(Zhang et al.
2017)The radio
transmitters uses

Optical fibre
This transmission
method are
widely used in
both tele-
communication
as well as in
computer
networking due
to its flexibility
(Craton et al.

Microwave
The microwave
radio waves uses
this transmission
technique
(Takahashi et al.
2018). The long
distance telephone
traffic programs can
be done with the

Satellite Transmission method
This kinds of
satellite
transmission
method are used
in communication
satellites,
telephone, radio,
internet and

Explanation
The concepts and
protocols of each of
the discussed
transmission methods
are different from
each other as a result
each of those
technique are used
for different purpose.

Parameter for different
choices
The factors which are considered regarding the
transmission of signals are as followings:
• Environmental conditions
• Cost of installation
• Ease of installation
• Distance
• Transmission rate

Compare the effectiveness of different transmission methods
The effectiveness
of the different
transmission
methods will be
discussed from this
point onwards in
this presentation.
