Heliograph
A Heliograph is a wireless telegraph and an early communication technology suited to the pre-electronic societies.
Contents
Description (Specifications)
It signals by flashes of sunlight (generally using Morse code) reflected by a mirror. It transmits communications across vast distances using optical methods transmitted to receiver and transmission stations.
The term comes from Terran words (helios (Greek: ἥλιος), meaning "sun", and graphein (γράφειν), meaning "write").

History & Background (Dossier)
The earliest stations tend to use fire basins or mirror-reflected light in the TL:1-3 tech epoch while later periods use flags, signal towers, or even early transmitted electrical impulses as in the more defined telegraph. These more advanced technologies become eminently workable by the TL:4-6 tech epoch.
