Pink Cell Tower

We would find it incredible that a corporation declares total monopoly over the colours we see and use, yet precisely that has happened with another part of the electromagnetic spectrum - radio - where big business now has exclusive rights over nearly all the frequency space public might otherwise use.

Taking the form of a fully-functional cell tower (or GSM base station), Pink Cell Tower is a work of extroverted infrastructure that intervenes upon this electromagnetic capture. It represents an alternative to the innocuous, beige and secretive corporate-owned and state-monitored mobile infrastructure billions have come to rely upon.

Solar-powered and open source, Pink Cell Tower demonstrates that infrastructure for calls and texts can not only be truly free, but publicly owned and operated with no dependence on statecraft nor corporations.

Pink Cell Tower also serves a website with instructions to replicate it (from BladeRF SDR to mastpole design & antennae), and a downloadable ISO complete with source code to flash onto a Raspberry Pi.

The downloadable ISO will be made available on this page before Feb 1, 2022.
