Passive Wireless Devices Using Extremely Low to High Frequency Load Modulation
Hubert Zangl, J. Michael, Thomas Bretterklieber, Anton Fuchs · InTech eBooks · 2010
The chapter presents passive wireless communication in the ELF to HF frequency range. With this technology, passive wireless devices can achieve ranges of up to several meters (at a low data rate), data rates of several megabit (at a low range). The devices can provide a well defined range of operation and they can permit communication in the vicinity or even through conductive or dielectric objects.
