Abstract :
Wireless, radiated far-field energy is being employed for charging a battery. This battery, while being recharged, is used to power a commercially of the shelf, low power, wireless sensor node. Propagation conditions in common office and house configurations are investigated experimentally. These experiments lead to the conclusion that instead of increasing the effective isotropic radiated power, a smart choice of antenna radiation pattern may help in increasing the operational distance of the wireless sensor node from the RF energy source.
