The use of UAV network cells may enable a wireless communication carrier to provide supplemental cellular network communication coverage to geographical areas. In some implementations, a first baseband processor of the UAV network cell may establish a first communication link with the ground network cell via a first antenna. The ground network cell may be connected to a core network of the wireless carrier network via a wired backhaul. Further, a second baseband processor of the UAV network cell may establish a second communication link with a user device via a second antenna. The first and second baseband processors may be communicatively coupled together. Accordingly, communication data may be routed between the user device and the core network through the first communication link and the second communication link.

Methods, systems, and apparatuses for providing layer-2 connectivity through a non-routed ground segment network, are described. A system includes a non-autonomous gateway in communication with a satellite configured to relay data packets. The non-autonomous gateway is configured to receive the data packets from the satellite at layer-1 (L1) of the OSI-model, generate a plurality of virtual tagging tuples within the layer-2 packet headers of the plurality of data packets. The non-autonomous gateway is further configured to transmit, at layer-2 (L2) of the OSI-model, the virtually tagged data packets. Each of the packets may include a virtual tagging tuple and an entity destination. The system further includes a L2 switch in communication with the non-autonomous gateway. The L2 switch may be configured to receive the data packets and transmit the data packets to the entity based on the virtual tuples associated with each of the data packets.

A control method and a control device in a heterogeneous three-dimensional hierarchical network, and a communication system are provided. The control method includes: obtaining a coverage mode of a terminal; when the coverage mode is single-layered sub-network coverage, setting a non-ground mobile communication sub-network or a ground mobile communication sub-network corresponding to the single-layered sub-network coverage to be in a standalone operating mode or an intra-layer carrier aggregation mode; and when the coverage mode is multi-layered sub-network coverage, setting the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, or the ground mobile communication sub-network and the non-ground mobile communication sub-network corresponding to the multi-layered sub-network coverage, to be in a cross-layer carrier aggregation mode. The ground mobile communication sub-network and the non-ground mobile communication sub-network use a same or unified radio access technology.

In one embodiment of the present disclosure, a satellite communication system includes a satellite constellation including a plurality of satellites in non-geosynchronous orbit (non-GEO), wherein at least some of the plurality of satellites travel in a first orbital path at a first inclination, and an end point terminal having an earth-based geographic location, the end point terminal having an antenna system defining a field of regard for communicating with the satellite constellation, wherein the field of regard is a limited field of regard, wherein the field of regard is tilted from a non-tilted position to a tilted position, and wherein the tilt angle of the tilted position is a function of the latitude of the geographic location.

An apparatus method and system are disclosed for dynamically implementing spectrum configuration plans in a satellite communication system. A spectrum configuration plan is created, and validated to determine if it can be utilized within the predetermined coverage area. If any errors are generated while validating the spectrum configuration plan, it is rejected. Otherwise, system components are configured to provide communication within the predetermined coverage area using parameters specified in the spectrum configuration plan. The spectrum configuration plan is also transmitted to all terminals in the coverage area. The spectrum configuration plan is subsequently implemented for all communication within the predetermined coverage area.

Modular broadband terminals that allow for the connection of a plurality of different modems are provided. The modular broadband terminals include a main connector board having common interfaces. The modems have specific interfaces that may be different from the common interfaces and from others of the modems. Each modem can connect with a converter adapter board that is configured to couple the modem with the common interface.
