“…In order to enhance the usability and mobility of mobile devices, a demand for wireless interfaces is strong for such devices. To meet this demand, we have studied an optical wireless USB system with 1 Gbit/s optical wireless transceivers [2][3], and demonstrated a wireless data transfer between a PC and a mobile phone using the system [3]. We focused on realizing a wireless data transfer in the previous work, however, a capability of a wireless power transfer is necessary for driving a USB device in a wireless USB 2.0 system.…”

We design and fabricate an optical wireless USB 2.0 system with a wireless power transfer. A coverage of the optical wireless transceiver is expanded by more than 30 % at the optimum distance for the power transfer, which can maximize the coverage of the system with the commercially available power transfer module. Wireless data and power transfer are successfully demonstrated between a portable music/video player and a PC using the fabricated system.
