MN503: Network Design Report for Calasanz School Project

This report presents a network design and implementation plan for the Calasanz School in Colombia, addressing the need for improved wireless network coverage to support e-learning initiatives. The project scope includes increasing wireless network coverage to support e-learning, and the report identifies key challenges such as budget constraints, limited staff, and the need to cover 33 classrooms across two buildings. The design concept prioritizes reliable and fast internet connectivity for teachers and students, with easy network management and future scalability. Hardware requirements are detailed, including switches, wireless access points, routers, and server specifications. The network design utilizes a hierarchical structure, with the ISP connecting to a router, which then distributes internet services through switches to departmental networks, ultimately providing internet access to users via various devices. The report also outlines project outcomes, such as network scalability and elimination of cable requirements, as well as limitations, including potential speed reduction compared to wired connections. The report concludes with a summary of the project's objectives, design, and outcomes, emphasizing its role in improving the school's network connectivity and supporting its e-learning program.

Project Scope:
The Calasanz School of Australia is currently facing various of challenges regarding
their new project of e-learning as the internet coverage within the school campus is not
enough for a perfect e-learning system. As the current network coverage is not enough for
the e-learning system currently the Calasanz School is executing a project for increasing the
wireless network coverage as strong and fast internet connection is required for the e-
learning [1]. Through this internet connection the students will be able to access various of
study materials that are available online and it will actually help the student in their learning
processes. E-books and online library will also become accessible to the teachers and the
students which is an important aspects of the e-learning processes [2]. As the e-learning
process is heavily dependent on a good internet connection the Calasanz School has opted
to improve its current network condition by increasing wireless network area coverage. So,
the main scope of this project is creating a specific design of the network which will be
capable of increasing the coverage area of the wireless network.
Challenges:
In this project there are various of challenges which is currently faced by the project
of the Calasanz School. Here one of the main challenges is the budget of the project.
Currently, the budget of the project is very much tight for the Calasanz School. Calasanz
School is also having some limited number of staffs which is creating another sort of
challenges for them. Due to the less number of staffs managing this huge network has
become challenging for the School. So in this case the network must be developed in such a
way so that becomes very much easy for the staffs to manage the network [6]. This project
also faces issues regarding the coverage area of the network as in the current situation the
network must be capable of covering total 33 classrooms which are divided into two
separate buildings. This two buildings are the high school building and the primary school
building. Due to the large network area coverage various types of challenges occurs in this
case which includes reduced internet speed as the strength of the network signal decreases
as the distance increases [3]. So in this case the network must be designed in such a way
that it does not lose its efficiency while the distance is increasing. In this case security of the
users is also a big concern. Here the new network must ensure that all the peoples who are
connected to the network is protected against any hacks or attack.
User Centric Design Concept:
Here the design concept of the network describes that the teachers and the students
will get a reliable and fast internet connectivity both the outside and inside of the classroom.

This designed network can be managed easily from a central location within the school
campus. This implies that any type of issues in the network can be detected and easily by
the IT team of the proposed network [7]. The network also have the properties of easy
upgrade which makes this system ready for the future. The developer of this network has
also the aim of reducing collision, data packet loss and congestion within the network and for
that the design of the network has been divided in many subnets [4]. Here each of the
department is configured with their individual SSID which helps the users to connect with
their respective department. This is very much useful for the management of the network.
The sensitive information is also secured within this network due to the implemented access
policy.

Cable:
Two types of cable is required UTP host connection cable and the Serial link Cable.
Serial Link Cable: The speed of this cable must be around 1 GBPS and the length should
be 550 m. Single mode and multimode fibre will be used in this case [8].

UTP Host Connection Cable: Maximum speed of this cable vary around 1 to 10 GBPS and
the required length is around 100m. CAT 6 cable can be used in this case.

Design of the Network:
(Figure 1: Design of the Proposed Network)
(Source: Created by the Author)

Justification: Here justification can be provided for the above designed network. In the
above structure of the network it can be seen that the ISP or the internet service provider is
connected directly with the router is routing the internet services to the switches, for the
distribution of internet services [9]. Departing from the main switch this connection goes to
the sub switches and through it is connected with the departmental network switches. From
the departmental network switches internet is provided to the teachers and the students and
they can access it through their devices which includes laptop, desktops and smartphones.
Thus it can be stated that this network diagram is very much appropriate for the Calasanz
School [5].
Outcomes:
The main outcomes of this project are discussed in the following section:
 The network is capable of extending itself in the near future if there is any type of
requirement.
 Through implementation of this network the Calasanz School will be capable of
eliminating the requirement of cable equipment for serving the internet at the bottom
level of the network structure.
 New network structure will also be capable of eliminating the unauthorised access to
the network.
 Many device can be connected to the network simultaneously without any
interruption.
Limitations:
 Less internet speed will be gained compared with the wired connection due to some
technical limitations.
 Internet speed may throughout the school campus as wireless network connection
has been opted in this case.
Conclusion:
From the above discussion it can be concluded that the presented network is capable
of improving the network connection of the Calasanz School. Here through this proposed
network, wireless internet connectivity has been provided to the teachers and the students
for the e-learning program. This network has also provided security to the users of it. Here a
brief discussion about the network has been done which consists project scope and the
challenges regarding the system. Also the user centric design concept has been evaluated
in this case. Following that network diagram and project outcome and limitations has been
shared in this case.
