The prototype enables automated 360°sweeps in either the horizontal (azimuth) or vertical (elevation) plane, facilitating signal strength measurements across a broad sub-6 GHz frequency range (70 MHz – 5.9 GHz).

We also evaluated propellers produced, via three different 3D printing techniques. The thrusters consistently produced an average peak thrust of 18 N at 310 W, with fabrication costs kept under 500 INR (approximately $6).
