Hertzian space

My understanding of hertzian space is that it consists of all the ‘real’ things/objects which happen outside of human perception, i.e. radio signals obviously exist physically, otherwise we wouldn’t be able to pickup radio stations, but we can not see them in the air all around us without a device that can pickup the signals we can not with our senses. This space operates with both natural and man made inputs, and can be used or interacted with in many ways.

Using Union Street as our location we used a Wi-Fi enabled phone to pick out one aspect of this hertzian space, i.e. Wi-Fi signals and strengths. The diagram below is my representation of this exercise, it shows the strength of signal by using different size and coloured circles, green and large are strong connections, red and small are weaker, these are given the name of the connection (therefore showing each signal has a unique identity, and it doesn’t just exist as one object) and also shows whether the connection is secure or not, denoted with a padlock image. I found this interesting as it shows points where you can interact with this entity.
