IDAT106 Workbook: Hertzian Space - Frequency Investigation

In this workshop we were asked to investigate how to map out a choice of frequency in the location of our choice. In our group we decided to pick the easiest frequency available to us; Bluetooth. Each of us carried a mobile device capable of picking up bluetooth frequencies and listing out their relevant ID names. Each mobile had a rough range of 20-40 metres so we could not just pick a small area. We decided to use the Roland Levinsky building and its floors to carry out our investigation.

It wouldve been an interesting idea to use WiFi as part of our data collection but that would have required carrying around a laptop picking up WiFi signals from the surrounding area, but as it is university campus there was a high chance of only picking up the campus WiFi.

With the Bluetooth data collected, I managed to create a map of the Roland Levinsky building purely out of the data and the locations at which we recorded the data.



By creating a visual map of the data shown above, it creates a whole new way of being able to view hertzian space. Its no longer just a compiled list of names collected from a mobile, its now a map containing a fraction of the hertzian space around us.
