FIT1047 Network and Security: Detailed WLAN Site Survey Report

This report presents a WLAN site survey conducted in a four-story building in Australia, focusing on the wireless network infrastructure. Using Microsoft Visio 2013, a floor plan was developed, and the survey involved scanning three WiFi access points across eight different locations using the NetSurveyor WiFi sniffing tool. The report details the technical characteristics of each access point, including network name, signal strength, channel, and 802.11 version. Findings indicate varying signal strengths and channel occupancy, with the 'Computer Lab Internet' access point consistently showing excellent strength across most locations. The report also identifies potential improvements, such as relocating access points to enhance coverage and replacing outdated devices. Additionally, the Ubiquiti discovery tool was used to identify radio access points in the area, providing a comprehensive overview of the wireless network environment. The pinging results shows the upload Mbps, ping ms and download Mbps.

Introduction
This report is a WLAN site survey. The report has produced a map for a four-storey
building in Australia which gives an overview of the wireless network. The floor plan was
developed using Microsoft Visio 2013. The building has Three WiFi access points. Netsurveyor
type of WiFi sniffing tool was used to scan the available Access Points; this was done in eight
different locations as shown on the map. For each location technical characteristics of the Access
Point was recorded i.e. the network name, signal strength, the channel used, and 802.11 version
supported.

About netsurveyor
It is a 802.11 WiFi sniffing tool which gathers information and statistics about the Access
Points and displays them in real time. This report adopted the tool as it easy to use and had a lot
of features. The information gathered about a certain access point can be displayed using
different views and charts. The tool can also be used in troubleshooting a certain Access point
and reporting to the network administrator about the performance of the Access Points
(Rappaport, 2011).

From the WiFi scanner, it shows that there were two Access Points which were detected,
which were Computer Lab Internet Access Point, Store WiFi Access Points. Some of the features
detected from the computer Lab Access Point are;
SSID: Computer Lab Internet
 MAC address: c4:6e:1f: ff: 6a:46
 Channel: 1
 Beacon Stregth: -33
 Becon quality: 501.1872
 Signal strength: Excellent
 Radio Type: OFMDD 24 (López & Zhou, 2010)
 Interference: None
Stores WiFi Access Point
 SSID: Stores WiFi
 Channel: 1
 Radio Type: OFDM
 Signal quality: Low and has no encryption
Notes
At point one, the coverage of computer Lab WiFi is at in maximum, infact as shown from
the diagram the signal strength is excellent. Another aspect is Computer Lab WiFi is encrypted
which requires one to login to access the wide area network. Both two access Points have a
channel occupancy of one (Backes, 2013).

Two access points as shown by figure 2 are competing for the same Channel; channel 1.
The two are configured in a search a way that they use the same overlapping channels. Access
Point three (Techno NYS) had a different channel which was unknown. Computer Lab Access
Point had no interference at six locations but at two locations the signal strength was excellent.
From my findings I noted, some attenuation in all the Access Points. This could have been
brought up walls. Only one Access Point; computer lab Access point which covered the desired
area. Other two access point only covered (AP1 and AP2 on figure 1) had very poor coverage.
This can only be improved by relocating the two access Points to increase the coverage. In
addition, AP3 device need to be replaced to a TP-Link type of access.
By pinging the site by using speedtest.com table 2 shows the upload Mbps, ping ms, and
download Mbps.

Findings
Beside the Four Access Points discovered, I also used a Ubiquiti discovery tool to find out the
radio Access Points of the Area. Figure 9 shows what I found out by running the Ubiquiti
discovery tool while Table one below shows the findings I foundafter scanning the site.

Table 1: Ubiquiti Discovery tool
From the analysis it is evident that Computer Lab WiFi always had excellent strength in
all the eight locations where WiFi scanning was done. From my view, one of the factors is that
there very minimal interference from the Access Points to the six locations. In addition, to this, it
is of my view that Computer Lab Access Point accessed the internet from the micro-tik type of
router which is able to spilt both network well if configured appropriately. Stores WiFi Access
Point was able to access the internet from a switch which.
Conclusion
Only two locations where the Access Point had good signal strength where one could
access the Internet with ease and one location where signal strength was at its best. The radio
Firmware which was used could also have affected the signal strength of a given Access Point.
Techno-NYS Access points was only strong at one location which was at point seven.
