A basic experimentation option will be communication between fixed nodes. This experimentation option is meant to be available on a continuous basis to experimenters (conditioned on resource constraints). It will not require any drone safety pilots or “in the field“ AERPAW personnel to run experiments. The example above shows two towers, each of which includes a PAW: a radio frequency equipment deployed by AERPAW. Such experiments can involve communication between two or more SDRs, as well as SDRs and other equipment (e.g., RF sensors, 4G/5G base stations, LoRa access station). 

Example experiment: Two fixed SDRs run srsLTE and srsUE, for testing different waveforms.
