Halfing and gnome engineers ensured that charted systems were covered in a network of relays. The schematics for manufacturing relays was subsequently broadcast across the network, allowing local systems to continue to spread the network even further.
Relays are simple an inexpensive to manufacture, and aside from the need for frequent maintenance, have served their purpose reliably and without much change in technology.
Certain relays, manufactured exclusively by Experifact, are mounted with miniature glodium-powered Zipp Drives, creating Zippways only large enough for signals to pass through. This allows for the net to be accessible nearly anywhere with minimal delay.
Some organizations have created private networks that relay signals only on particular frequencies, and occasionally individuals may broadcast pirated signals from remote relays.
