"This paper deals with trial focused on a path loss measurement in urban area using a low altitude airship. Experiments were proposed at 2.0 GHz, 3.5 GHz and 5.5 GHz frequencies representing the frequency band for 3G, mobile WiMAX and WiMAX systems. The trial was aimed at rooftop diffraction loss and penetration loss measurement. The goal was to obtain experimental data that can be used to planning of communication systems delivered via High Altitude Platforms (HAPs) [1]."@en .
