In a dense environment of loosely-coupled wireless charging pads to which out-of-band signalling is applied, cross-connection errors occur according to the wireless communication distance of out-of-band signalling. A cross-connect abatement technique using received-signal-strength-indicator measurement is proposed to prevent this problem and to provide stable wireless charging. To evaluate the performance of the proposed technique, two compact wireless charger environments are created in an RF shield room. The experimental results indicate that the wireless charging system using the proposed technology provides wireless charging services without cross-connection errors.
