MN503: Network Design for Calasanz School Project Report

This report presents the network design for Calasanz School, addressing the need for comprehensive wireless coverage across its primary and high school buildings. The design incorporates routers from Cisco, switches from TP-Link, and EAP120 wireless access points with Qualcomm Atheros chipsets to ensure strong and reliable wireless signals. Security is implemented through user verification via a captive web portal and VLANs for network segmentation. The report details the logical design components, including the router's role in internet distribution and the switch's function in providing network access within each building. The EAP120 access points are strategically placed for optimal wireless coverage, managed by a dedicated network management software. The report also highlights the use of the Qualcomm Atheros chipsets for strong wireless signals and the use of VLANs for network segmentation. References to relevant research papers are also included.

Presenting Network Design of
Calasanz School

Network Requirements
 Calasanz School comprises two main
buildings – Primary School Building and
High School Building.
 The Primary School Building requires 15
connections for devices in classrooms.
 The High School Building requires 18
connections for devices in classrooms.
 Routers, switches and devices for setting
up wireless connectivity in both
campuses and classrooms to be obtained
from leading manufacturers.
Typical setup of wireless access points and
POE switches:

Network Design

Logical Design
Components:
 The router, assumed to be Cisco 2811 gets internet from Internet
Service Providers (ISP) and channels the connection into appropriate
subnets for two buildings.
 The TL-SF1048 switch from TP-Link distributes the network access
among the required devices located in the lab rooms of the respective
building.
 The wireless devices include the EAP120 wireless access points and the
Qualcomm Atheros 560MHz chipset. These enable sharing of strong and
reliable wireless connections across the campus including classrooms.

Security – User verification
authentication
 A captive web portal is provided
by Calasanz to the members for
acquiring different kinds of
services.
 Different access levels to the
portal is ensured through user
verification process.
 Authentication of user
verification occurs in the Radius
servers [1].

Security – Use of VLANs to segment
network access
 Access to network of Calasanz
School is segmented with the
use of VLANs [4].
 Networrk Administrators use
VLAN 3 or Admin VLAN.
 School staff, teachers and
students use VLAN 2 or User
VLAN

Wireless Devices – EAP120
 These are the access points
placed on rooftops for providing
wireless network access.
 These can be connected directly
to switches or via POE hubs and
switches [2].
 Thus these access points are
flexible to implement

Wireless Devices – Qualcomm
Atheros Chipset
 These are the 560 Mhz chipsets
that built by Qualcomm.
 They ensure strong and reliable
wireless signals can be
generated.
 This device can be use to deliver
wireless connectivity to more
than 1000 users.

Network Management Application
 The EAP120 wireless access
points provide a free to use
network management software
[3].
 This application can be utilized
to manage the entire network of
Calasanz School.
 Key features of the software are
centralized configuration and
active network monitoring.
