Wireless USB Technology overview USB Wire replacement technology Up to 127 devices Matches datarate of USB 2. 0 (480 Mbps) Hub-and-spoke connection relationship Connection model is a wire replacement Point-to-point connections Between WUSB host and peripheral W-USB cluster W-USB Host with one or more peripherals (up to 127 addressable devices) Host scheduled data communications W-USB Clusters may co-exist within an overlapping spatial environment Support for legacy USB devices Dual role devices

Phase 1 Enabling the Market USB 2. 0 Certified Wireless USB Host Wire Adaptor: HWA USB 2. 0 Certified Wireless USB Device Wire Adapter: DWA

Phase 2 Pushing for Native Devices Wireless USB adapter (HWA or WHCI) Wireless USB device wire adapter (DWA) Digital camcorder Webcam External storage Scanner Printer DSC

What Is Wi. Net? Wi. Net = “IP over UWB” Wi. Net specification defines an Ethernet encapsulation protocol, Layer-2 bridging, Power Save and Qo. S UWB has large frequency band allocations Gigabit data rates for wireless IP transport

Power Save Every device advertises in its beacon (as part of Wi. Net ASIE) its LAP Cycle and an active cycle start time (ACST); every device has its own LAP Cycle = period between the start of two consecutive LAPs = ∆*2 n, where n = 0, 1, 2, …, N, and N and ∆ are fixed Let m = max (ni) = max of all LAP indexes of neighbors; GAP periodicity = ∆*2 m; Broadcast/multicast “control” traffic during GAP
