Portable and low cost channel sounding platform for VHF / UHF IoT propagation research

Abstract

This paper presents work into realising a cost-effective and portable platform to support Internet of Things (IoT) propagation research at VHF and UHF. The sounding receiver uses a low cost RTL-SDR, Raspberry Pi and touchscreen. The platform runs dedicated channel sounding DSP algorithms written in Python. The resulting platform is a portable and convenient propagation measurement tool, covering 27MHz to 1.7GHz. Initial results from a city measurement campaign at 71MHz and 869.525MHz are presented, showing channel response and interference.
