What is it?
Hertzian space is a subject which exists in the realm of society but yet is invisible to our own eye's.
To be more specific it is the collection of waves and frequency's, e.g. Bluetooth, radio and Wi-Fi that surround our very existence. Millions upon millions of packets of data being sent from building to building, city to city through our own bodies and its something we rely upon.
The safety of such things such as bluetooth can be questionable, but many remain care free. However technologies with huge data ranges that are capable of passing through buildings and the human body does have its doubters.
With that said it is a very interesting subject and can be visually represented for anyone to see.
How can we see it?
Using our own project site (Union street) as a starting point we ventured along this road using a phone with such Wi - fi software as Kismet to create a data map that showed signal strength and weakness. The map below also shows the security type of the Network. From the map it was easy to see the data that makes up Hertzian space. Note that this is only one device (Wi-fi) If mediums such as bluetooth and radio were included in this map I am sure that the map would be full of colours.
Key:
- Red circle = Weaker signal
- Green circle = Stronger signal
- Padlock = secure network
