Summary
The objective of this report is about going through the requirements of Calasanz School Network and
about explaining the wired and wireless network infrastructure for the main buildings of Calasanz
School. After summary of all requirements get provided, logical design of the network get discussed.
The respective benefits to Calasanz School from the network layout and design are also mentioned.
The benefits are primarily related to network performance, network connectivity, network security
and network convenience. The performance of network directly depends upon the manner in which
the parts and components of network are connected with the rest as also the number of devices
included. After that this report speaks of security that is ensured by this network and discusses the
convenience gained from using wireless connectivity using the said product. Lastly the report
finishes with observations mentioned in concluding notes.

Introduction
This report goes through the requirements of Calasanz School Network and about explaining
the wired and wireless network infrastructure for the main buildings of Calasanz School. After
summary of all requirements get provided, logical design of the network get discussed [9]. The
respective benefits to Calasanz School from the network layout and design are also mentioned. The
benefits are primarily related to network performance, network connectivity, network security and
network convenience. The performance of network directly depends upon the manner in which the
parts and components of network are connected with the rest as also the number of devices
included. After that this report speaks of security that is ensured by this network and discusses the
convenience gained from using wireless connectivity using the said product. Lastly the report
finishes with observations mentioned in concluding notes.
Study of Network
Project Scope
 The primary school building should provide connections to 15 classrooms.
 The high school building is to provide connections to 18 classrooms.
 All these 33 classrooms is to have wireless connectivity.
 Wireless network access should also be available to the 6 departments of the School [5].
 The members of the school should be able to access wireless connections from campus and
classrooms.
Challenges in Execution
 Bringing wireless access to campus is more complicated than for classrooms as the
additional equipment typically require power points.
 Multiple switches must be installed in the buildings of Calasanz School to connect the access
points to the network.
 Authentication process for verification of users consume immense resources in the server
side.
Summary of Requirements
The accumulated number of classrooms that are present in both the primary and high school
buildings are 33. These classrooms have the ability to accommodate wireless connectivity excess of
1290 students and also a total of 83 teachers with support for staff from other departments of the

school also [1]. In the high school building there are 18 classrooms and in the primary school
building there are a total of 15 classrooms. These buildings of Calasanz School are to obtain network
connections from core switch connected to the main router. The core switch distributes connections
to respective switches for wireless access points of classrooms from trusted brands. Access to
network by these user devices from all classrooms and the campus of buildings are ensured via
wireless accessibility.
Logical Design of Network
Internet access can be acquired from any of the Internet Service Providers (ISP) [7]. The ISPs
always stay connected with the internet that basically refers to the broad physical interconnect of
networks which enables the services of the World Wide Web (www) [8]. Either of the main buildings
– primary or high school buildings receive the internet in their router and provides it to the other
directly by cables from the core switch. These buildings distribute the network obtained from the
core switch to wireless access points using distribution switches [3]. The wireless access points
provide access to all devices requesting network usage.
Connectivity/Performance
Through the logical design it can be seen that ISPs stay connected with servers of
multiple networks in the internet thus becoming a part of it. The network connection is
routed by ISPs to respective users which include the Calasanz School and provides the
services in form of several packages segmented on the basis of network bandwidth, usage
capacities and connections needed. The Calasanz School router connects to routers of these
ISPs and routes the received connections to the network switches of the buildings. These
are the TL-SF1048 switches provided by TP-Link [10]. The switches are responsible for giving
network access to respective wireless access points of the classrooms. These are the EAP120
wireless access points provided by TP-Link and are installed on all the 33 different
classrooms as also in many other sections of the two buildings such that wireless access to
the network can be available in campus premises also. Every wireless access point has ability
to serve excess of 1000 users, and hence meeting the requirements of about 1300 students
as well as 83 teachers and other staff cannot be an issue. This is how less traffic is achieved
and it assures effect network bandwidth and reliable pings to devices continuously.

Security and Segmentation
The security aspect of the network is addressed mainly by two key meethods. One is
the verification of user login to the web portal of the school. The other method is
segmentation of the network by using VLANs. The verification of user credentials occur
when members of Calasanz School attempt to avail services from the captive web portal [2].
The user login mechanism enables multiple access levels to company data be assigned
among the different members like students, teachers and staff members of other
departments. Authentication of user credentials verification is done over the Radius servers
in the two buildings [6].
Access levels to staff members of Calasanz School are then segmented as per
requirements of the different departments. These departments belong to the Human
Resource (HR), Admin, Academy, Sports, Finances and IT Support respectively.
Access to entire network of Calasanz School gets segmented among network
administrators and all other users of this network by making use of virtual local area
networks or VLANs [4]. The VLANs are configured in those several switches present in main
buildings of the school. These VLANs are being used so that a variety of controls and policies
can be set for varying groups of members by means of several virtual networks from same
physical network.
Convenience and Features
Wireless devices like EAP120 is either connectable to distribution level switches of
the buildings by direct cabling not having to worry about power arrangements like in POE
(Power over Ethernet) switches based setups or in traditional ways. Thus wireless access to
outdoor premises becomes easy and flexible to implement instead of overly relying on
larger higher grade antennas and even the physical infrastructure requirements to support
it. EAP120 additionally provides network management software which comes included with
the product supporting features like centralized network configuration or even real time
monitoring of the network. These applications are usually pretty costly to acquire and aren’t
always included with other wireless access points from competition.

Conclusion
In conclusion, the observations drawn from the report suggests that the report goes
through network requirements of the Calasanz School Network and about explaining the
wired and wireless network infrastructure for the main buildings of Calasanz School. After
summary of all requirements get provided, logical design of the network get discussed. The
respective benefits to Calasanz School from the network layout and design are also
mentioned. The benefits are primarily related to network performance, network
connectivity, network security and network convenience. The performance of network
