Disclosed embodiments relate satellites using a Software-Defined Radio ('SDR') system. In one example, a geostationary (GEO) satellite includes an antenna system including multiple antennas, each configured to provide a spot beam having an adjustable throughput for a terrestrial coverage area while the antenna is in an active state and the satellite is in orbit above the Earth, a front-end subsystem communicatively coupled to the antenna system having an input side including an input filter and an analog-to-digital converter, and an output side including an output filter and a digital-to-analog converter, and a software defined radio (“SDR”) communicatively coupled to the antenna system via the front-end subsystem. The SDR, in response to a surge modification request, modifies a throughput of each active antenna by increasing or decreasing a share of a satellite power budget allotted to the antenna by deactivating or activating a previously active or previously inactive antenna, respectively.

Systems and methods for leveraging multipath wireless transmissions for charging devices within multipath signaling environment. Techniques according to the present technology include determining a received signal strength of a radio frequency signal received via a plurality of paths at two or more antennas of a plurality of antennas of an antenna array. The techniques also include configuring parameters for transmission of a wireless power signal over one or more paths of the plurality of paths for which the received signal strength exceeds a threshold value. The techniques further include directing at least a portion of the plurality of antennas to transmit the wireless power signal over the one or more paths according to the parameters.

The disclosed wireless transmitter estimates a client location in space and transmits power in the form of electromagnetic (EM) waves to that location. In response to receiving the power, a client sends a power request signal. In some implementations, the power request signal includes a request that the wireless transmitter transmit more power to the client. In response to the power request signal, the wireless transmitter can modify the power transmitted to the client to increase/decrease the amount of power the client is receiving. For example, the wireless transmitter can modify the emitted EM waves to increase coherent addition or decrease coherent addition at the location of the client to increase the amount of power the client receives. In some implementations, the wireless transmitter modifies the phase distribution of EM waves to increase the amount of power a client receives.
