A system, apparatus and method provide wireless communications to a geographical area. The system includes at least one atmospheric platform serving as a central relay or node using a star network topology for the geographic area. The atmospheric platform carries a payload that comprises communications equipment. The system further includes a plurality of user equipment units located within the geographic area and at least one ground station or gateway for providing an information pathway between the user equipment units. The gateway has network processing and switching equipment for routing the information between the users. A wireless trunkline carries signals between the gateway and the atmospheric platform. The apparatus and method comprise gateway and payload uplink portions and downlink portions. The downlink portions aggregates and de-aggregates user generated information from the platform to the gateway. The uplink portions de-aggregate and aggregate the information and route the information with the network switching equipment to intended user equipment units, from the gateway to the platform. The gateway may also provide information pathways from the platform to user equipment units outside of the geographic area through existing communications infrastructure. The system, apparatus and method utilize a wide, non-contiguous band of spectrum in point-to-point links to carry the combined signal traffic from a multitude of subscribers on the ground to the communications switches at the gateway and vice versa, via the airborne platform. The use of wireless trunklines enables all types of switching, including circuit, cell, packet, or frame, or any combination thereof, to be performed by standard equipment housed in facilities on the ground rather than by specially designed equipment located on the airborne platform.
