Galactic Signal Network

The Galactic Signal Network (GSN) is the term collectively referring to the thousands of transmitters and relay nodes that allow for communication and Internet access on an interstellar scale.

History
The first space-based relay nodes appeared in the galaxy as early as 7,000 BBY, with communication before that taking place through messengers and encrypted codes. The first organization to mass produce these nodes was the Republic's Messenger Guild, which later developed into the Department of Stellar Communication. By 100 BBY, most of the galaxy's nodes were owned and operated by the HoloNet, ISBe, and Microsoft corporations.
