Apparatuses, systems, and methods for pairing/unpairing unmanned aerial vehicles (UAVs) to/from UAV controllers (UACs). A UAV and/or a UAC may initiate, based on a triggering condition, a paring/unpairing of the UAV to/from a host UAC and receive, from a network, a configuration update that may confirm the paring/unpairing of the UAV to/from the host UAC. The triggering condition may include at least one of the UAV moving from a location designated as controlled by the host UAC, the UAV moving into a location in which the host UAC is restricted from controlling the host UAV, and/or the host UAC losing signaling capabilities. The configuration update may include at least one of a cause code, an identifier associated with the UAV, an identifier associated with the host UAC, an identifier associated with an unmanned aerial system (UAS).

An airborne RF-head platform system and method. Here, much of the computational burden of transmitting and receiving wireless RF waveforms is shifted from the airborne platform to a ground baseband unit (BBU). The airborne platform, which will often be a high altitude balloon or drone type platform, generally comprises one or more remote radio heads, configured with antennas, A/D and D/A converters, frequency converters, RF amplifiers, and the like. The airborne platform communicates with the ground baseband units either directly via a laser communications link, or indirectly through another airborne relay platform. The airborne RF-head communicates via various wireless protocols to various user equipment such as smartphones by using the BBU and the laser communications link to precisely control the function of the airborne A/D and D/A converters and antennas. This system reduces the power needs, weight, and cost of the airborne platform, and also improves operational flexibility.

A system for subsurface transmission includes an array of very low frequency (VLF) transmitter nodes supported by semi-autonomous maritime, airborne, or space platforms spaced at regular intervals from their nearest neighbors and phased to localize VLF coverage to some desired area on a body of water.
