Abstract
A coil-in-coil structure (100) is formed within two devices (106, 108). The coil-in-coil structure (100) enables both wireless charging and secure pairing between the two devices (106, 108). The coil-in-coil structure (100) permits expanded wireless functionality using a single transmit coil (104) at a host radio device (108) and a receive coil (102) at an accessory device (106). A plurality of different accessory devices (606) can be interchangeably accommodated via a single host port (114) of the radio device (108).
