Phantom Terrains →

Very cool project by Frank Swain, Daniel Jones, and Stefanie Posavec:

The map below visualises the wireless network landscape on a walk around BBC Broadcasting House. Stronger network signals are shown as wider shapes; the colour of each shape corresponds to the router’s broadcast channel (with white denoting modern 5Ghz routers), and the fill pattern denotes the network’s security mode.

Beneath the map is an audio recording of part of the same walk, as heard through the Phantom Terrains sonification interface. The sound of each network is heard originating from the router’s geographical location, producing clicks whose frequency rises with the signal strength — akin to a layered series of Geiger counters. Routers with particularly strong signals “sing” their network name (SSID), with pitch corresponding to the broadcast channel, and a lower sound denoting the network’s security mode.
