WorldSat Aerial Sphere

The WorldSat Aerial Sphere (WSAS) is a device invented by WorldSat.

Overview
WorldSat Aerial Spheres are large weather balloons filled with helium that act like satellites which can be used to connect to CitiNet and extend its radius. It can presumably interface with other Aerial Spheres to extend the network even further.

After the DataKrash destroyed vital communications infrastructure, WorldSat Communications Network invented the Aerial Spheres as a way of transferring digital communications from one city to another, but the technology was insufficient for forming permanent connections.
