Assignment 1 Overview of Internetworking MN503
A case study entitled “Chase Grammar School Accelerates Learning with BYOD” is uploaded with
the assignment 1 folder, and the link for the case study is provided as an appendix. Based on the case
study, Leo Li, Director for Administrator at the school, is highly concerned with the reliable, highspeed internet connection whether wired or wireless. He thinks that pupils are digital natives and
they thrive in the multi-media environment. He further adds that one cannot underestimate the
importance of rich and varied contents in the landscape that internet provides.
The case study focusses on the wireless solution and installation of additional wireless access points.
As a result, the current throughput rate is recorded as 51 Mbps compared to a patchy 20 Mbps
before. All seems good with the Chase Grammar School’s network at the moment. However, there
has not been any updates and upgrades on the existing wired infrastructure.
In addition to the wireless infrastructure, you as a network consultant strongly believe that the
network experience of the end users at the school could have been further enhanced with the
updating and upgrading of the current sluggish wired infrastructure. You tentatively figured out that
with the proper upgrade of the wired network the throughput could go up to 90 – 100 Mbps.
Based on your understanding of the case study prepare a report on the proposed wired and wireless
network design for Chase Grammar School. The report on the proposed design should have the
following contents.

Case Study
Chase Grammar School
Accelerates Learning with BYOD
Chase Grammar
School
Industry: Education
Location: Cannock,
Staffordshire, England
Profile: Chase Grammar
School is an independent
school in Cannock, near
Birmingham, right in the centre
of England. It offers education
from nursery, GCSE, right up to
A Level.
“You can’t underestimate
the importance of rich and
varied content in the
learning landscape. Pupils are
digital natives who thrive in a
multimedia environment which
relies on a reliable, high speed
internet
connection whether it
is wired or wireless.”
– Leo Li, Director for
Administration at Chase
Grammar School

About Chase Grammar School
Founded in 1879, Chase Grammar School has a
dedicated team of teachers and administration
staff committed to nurturing children to reach their
full potential. With 75 teachers and support staff,
330 pupils and class sizes of no more than 15, the
school benefits from a caring culture, supporting
local and overseas students from a range of
backgrounds and cultures.
Technology is an essential part of the educational
mix providing access to multimedia learning making
the IT infrastructure and in particular wireless
essential components of the learning journey. Many
teaching resources are hosted on the web and
teachers often access rich content from a variety
of sources including Dropbox, TeacherTube and
YouTube to enrich the learning process reinforcing
critical curriculum topics. Most students use mobile
devices including laptops and tablets to prepare
homework and support learning. The web also
provides valuable opportunities for self-driven
learning, enabling pupils to be secure in their
knowledge and develop the skills required to apply it
to real-world scenarios.
Wireless Bottleneck
For the school to take full advantage of the facilities
at its fingertips it invested in three 70Mbps fibre
optic connections. With a theoretical 210Mbps
available, bandwidth should not have posed a
problem. However, the existing Edimax wireless G
infrastructure and period buildings with thick, solid
walls seriously limited the real world download
and uploads speeds for staff and students alike.
Registering a maximum download speed of 20Mbps
there was plenty of scope for improvement. With
400 people on campus every day, 130 boarders and
a further 120 day pupils carrying an average of two
connected devices each, the existing infrastructure
was under a lot of strain. It was boarders who were
most affected, the legacy access points would
permit only 5 devices to connect simultaneously,
and with an average of 12 students in each
accommodation block should a 6th attempt to
connect it would crash losing all connections. As
a home away from home for boarders it’s vital for
Chase Grammar School to provide all the
essentials, including WiFi. Foreign students in
particular are heavy bandwidth consumers, regularly
using VIOP solutions like Skype, FaceTime and
Google Hangouts to stay in touch with friends
and family back home. This lead to issues with
bandwidth hogging to the extent that some pupils
struggled to load webpages before the browser
timed out. This was a major cause of frustration
especially amongst students preparing for exams
trying to access past papers from websites like
AQA. It also rendered the intranet, developed by
the school as a one stop revision too, redundant
because resources took too long to download.
Learning in a Safe Environment
As an essential part of the school infrastructure it
became clear that the wireless infrastructure and
policies needed
to be rethought and revamped. This provided the
perfect opportunity to develop, roll out and enforce
a BYOD policy which, amongst other things, which
prohibited P2P sharing and downloading. “You can’t
underestimate the importance of rich and varied
content in the learning landscape. Pupils are digital
natives who thrive in a multi-media environment
which relies on a reliable, high speed internet
connection whether it is wired or wireless,”
commented Leo Li, Director for Administration at
Chase Grammar School.
Case Study
“The TP-LINK team did a great
job. They came to the school
and mapped the wireless
and current infrastructure.
They were very discrete so
lessons weren’t disrupted.
Then they prepared a
thorough report detailing
their findings and providing
practical recommendations
to maximise coverage and
performance. It was a very
valuable tool that helped me
build a solid
business case to secure
budget.”
– Leo Li, Director for
Administration at Chase
Grammar School
“Kids are smart and will
exploit an opportunity to
download the latest films and
games, it’s our responsibility
at Chase Grammar School to
focus on the quality of
education and therefore
develop and enforce
responsible internet policies
and these access points do
just that.”
– Leo Li, Director for
Administration at Chase
Grammar School
Network Site Survey
Before investing in additional hardware, the school
needed a clear picture of the existing wireless
landscape. Leo therefore organised a site wide
network survey to assess the wireless coverage,
strengths and weaknesses. Taking advantage of
the free TP-LINK network site survey Leo organised
a visit from the TP-LINK Team. Within a day the
site survey team conducted a thorough analysis
of the entire campus to build a clear picture of the
current signal strength and map of the current
IT infrastructure including physical barriers. “The
TP-LINK team did a great job. They came to the
school and mapped the wireless and current
infrastructure. They were very discrete so lessons
weren’t disrupted. Then they prepared a thorough
report detailing their findings and providing practical
recommendations to maximise coverage and
performance. It was a very valuable tool that helped
me build a solid business case to secure budget,”
reflected Leo.
As a result of the wireless survey and the emphasis
on empowered learning, Chase Grammar School
needed a single solution that would not require
much precious time and resource to install and
manage going forward. With this in mind, the
TP-LINK EAP120 ceiling mounted access points
provided the ideal solution, easy to install and
packed with valuable features. Leo found the cluster
function particularly useful enabling him to log on to
any access point within the network making it the
master providing real-time access to the rest of the
access points. This feature enables him to change
settings across the network or roll out firmware
updates in real-time.
Solid Infrastructure for Learning
The EAP 120’s captive portal function was a
critical feature in the decision making process. It
has been put to good use supporting the school’s
emphasis on empowered learning and BYOD.
Students are required to log on to the network
via the authentication page which reiterates the
schools internet policy, restrictions and rules at
the beginning of each session. This feature also

optimises data rates for each SSID to maximise
bandwidth efficiency across the network for better
Wi-Fi performance. In addition to providing better
wireless, it also provides an added layer of security
ensuring only authorised students and staff can
access the network. “Kids are smart and will exploit
an opportunity to download the latest films and
games, it’s our responsibility at Chase Grammar
School to focus on the quality of education and
therefore develop and enforce responsible internet
policies and these access points do just that,”
commented Leo.
With a total of 15 EAP 120 deployed across the
campus the results were instantaneous. From
a patchy 20Mpbs around the school, students,
teachers and administrators were recording up to
51Mbps throughout the school buildings, plenty of
bandwidth to access learning resources and stream
rich content to the classroom. Leo Li commented,
“The installation was extremely straightforward. It
was a simple matter of plug and play. The cluster
function in particular saved me many hours
configuring each access point. On a day to day
basis I can log into the closest access point to see
how the whole network is performing and make any
tweaks necessary.”
Future Developments
The next steps in wireless optimisation involve
replacing the old switches currently limiting the
overall network performance. Leo intends to use
VLan tagging to different ports, traffic management,
bandwidth management and QoS to control
bandwidth and prevent high intensity activities such
as torrenting affecting performance across the
rest of the school. To better track individual usage,
Leo intends to roll out Active Directory giving each
authorised user a unique username and password.
Using Active Directory, the network administrator
can identify individual users, how many devices
they have connected to the network and track what
they are doing, an important step in enforcing the
school’s internet policies and retain the focus on
learning.
