This paper presents the results of ambient RF energy measurements conducted at 23 locations in Calgary and area, including a mix of indoor/outdoor, rural/urban, public/private locations across frequency bands for cell phones (824-960MHz, 1710-2170MHz) and unlicensed industrial, scientific, and medical devices (2.4-2.5GHz, 5.150-5.875GHz) using a spectrum analyzer. A best case test scenario where an active RF source was nearby a user was also conducted. It was found that RF energy at the measurement locations is generally too low or too inconsistent for energy harvesting. Analysis of measurement data reveals that up to 37% and 11% of the locations can attain a peak power of at least -30dBm and -20dBm, respectively. However, ambient RF harvesting is probably feasible with an active source nearby. The findings open the door for further research in intended RF energy harvesting with a dedicated transmitter for simultaneous wireless information and power transfer in future generation sensors powered by ambient RF energy.
