Honours Research
In 2007, I completed my BSc (Honours) in Computer Science and Information Systems at Rhodes University This page serves to describe that project.
Project Title:
IEEE 802.11 Signal Source Mapping using Low Cost Spectrum Analysers
Abstract:
The research presented by this dissertation, describes an investigation into visualising 2.4 GHz Wi-Fi networks and discovering the location of 2.4 GHz devices using a collection of low cost MetaGeek WiSpy 2.4 GHz Spectrum Analysers. By combining frequency VS amplitude data received from WiSpy spectrum analysers and graphically displaying the data we can effectively discover 2.4 GHz Wi-Fi devices and interference sources. Research was done into interference sources that hamper the performance of Wi-Fi throughput, these include any radio frequency devices which operate in the 2.4 GHz band. To practically meet these goals the WiSpy SSM Tool was produced, which includes two applications (WiSpy SSM Collector and WiSpy SSM Compiler) and an webservice. Multiple WiSpy SSM Collector applications are deployed in the area under investigation and collect signal data using a WiSpy spectrum analyser connected to a computer. The collected data is transmitted to the webservice and stored in a database. The WiSpy SSM Compiler retrieves stored information and displays this to the user in a simple and easy to understand manner for interpretation. The results obtained from the WiSpy SSM Compiler were conclusive in that by using three spectrum analysers we were able to locate Wi-Fi devices fairly accurately.
