Interspace communication technology refers to devices that enable the rapid transmission of data across great distances. Composed of an intricately connected web of space stations and satellite-based relay towers, the network facilitates quick information transfer by sending burst packets of data from station to station. During the Human Colonial Expansion Era from SEY 2380 to 2530, these relay stations were key in accelerating the growth of Human settlements located outside the Sol system. With a quick, reliable communication network on hand, colonists were reassured that they would be able to stay in touch with their loved ones and request aid if needed without waiting months between messages. The network also facilitated travel and trade, and allowed the central government to supervise even long-distance colonies.
