London RF survey for radiative ambient RF energy harvesters and efficient DC-load inductive power transfer


This paper presents experimental results of energy harvesters working from ambient RF sources and an efficient inductive power transfer (IPT) system. A city-wide RF spectral survey was undertaken outside all of the 270 London Underground stations. Results from this unique survey demonstrate that DTV, GSM900, GSM1800 and 3G are the highest contributors. As a… (More)
