This paper explores the use of the high data rate (HDR) capability of ultra-wide band (UWB) wireless technology for large file transfer between multimedia-cards (MMC). First, we analyze the challenges of adding a UWB transceiver onto an MMC. Secondly, we study the use of a Bluetooth (BT) radio available from the MMC's host as a control link. This solution permits to fully utilize UWB high data rate capability for data transfer, while limiting the needed modifications of the existing MMC and the terminal's upgrade to application software only. An efficient automatic resend request mechanism for reliable file transfer is also proposed. Finally, we describe a prototype implementation based on mobile terminals, multimedia cards interface, and impulse UWB radio.
