- 3. INTRODUCTION :Wireless USB is a wireless technology which enables the high speed computer peripheral interface wireless.Wireless USB will be based on the Ultra-Wideband (UWB) & radio efforts by the WiMedia Alliance. Wireless USB interest group was formed in 2004.Wireless USB has an advanced power management system which consumes very low power. 1/2/20113CET DIGITAL SIGNAL PROCESSING
- 4. Introduction ContUWB supports high bandwidth (480 Mbps) but only at limited range (~3m). Applying this wireless technology to usb frees the user from worrying about the cables; where to find them, where to plug them in, how to string them so they dont get tripped over, how to arrange them so they dont look like a mess. Wireless USB is used in game controllers, printers, scanners, digital cameras, MP3 players, hard disks and flash drives.1/2/20114CET DIGITAL SIGNAL PROCESSING

- 6. Reasons For Wireless USBWires are restrictive.Multiple wires can be a hassle. Wires slower than wireless solutions.Inadequacy of current wireless solutionBluetooth.Bandwidth of 3 Mbps not enough for higher demand applications (Video, HDTV, Monitor).Wi-Fi.Expensive. Too much power usage for mobile devices.1/2/20116CET DIGITAL SIGNAL PROCESSING
- 7. ARCHITECTURAL OVERVIEWUSB System Description.油A USB system consists of a host and some number of devices all operating together on the same time base and the same logical interconnect. A USB system can be described by three definitional areas:USB interconnectUSB devicesUSB hostUSB interconnect:TopologyData Flow ModelsUSB Schedule1/2/20117CET DIGITAL SIGNAL PROCESSING
- 8. Hub and Spoke topologyTopology : Wireless USB connects USB devices with the USB host using a 'hub and spoke' model. The Wireless USB host is the 'hub' at the center, and each device sits at the end of a 'spoke.1/2/20118CET DIGITAL SIGNAL PROCESSING

- 11. SECURITY:Encryption Methods The standard method of encryption for the first generation of Wireless USB is AES-128 Counter with CBC- Mac Wireless USB also supports public key encryption, but only for authentication The CCM encryption suite provides 128 bits of security for run-time operation.1/2/201111Keyboard MCUReceiver MCU128-bit Key128-bit KeyCipher StreamWUSBCipher StreamWUSBData Payload+Data Payload+CET DIGITAL SIGNAL PROCESSING
