The Wireless USB Promoter Group is crafting a specification for a Wireless USB standard that will provide high-speed connectivity over a distance of 10 meters. The data rate targeted is 480 Mbps which is comparable to the speed of wired USB 2.0 and much higher than Bluetooth.This technology is capable of providing high-bandwidth multimedia streaming and data transfers.It will maintain the host-to-device architecture and usage models.
UWB The basic transport mechanism for Wireless USB is the ultra-wide band (UWB) radio platform. Multiband OFDM Alliance (MBOA) and the WiMedia Alliance has been focussing on this standard. The platform consists of two core layers: 1)UWB R ADIO LAYER UWB transmits short, fast, low-power wavelets of energy over a very wide band of frequencies.Whereas conventional technologies like radio frequency (RF) and spread-spectrum technologies (SS) such as Bluetooth and 802.11a/g transmit a single continuous carrier wave over a specified frequency. UWB uses the 3.10 to 10.6 GHz slice of the radio spectrum. The usage of very broad band and restricted power provides the high speed and limited range of UWB and also also enables spectrum reuse. 2)THE CONVERGENCE LAYER It serves as an interface between the UWB radio layer and UWB-based applications and allows multiple applications to share a single radio. WUSB CLUSTER TOPOLOGY It uses a simple hub and spoke topology, with point-to-point connections between the host and the devices connected to it. The host schedules and initiates data transfers to the devices in the cluster by allotting time slots and bandwidth to each connected device. The host can connect to as many as 127 devices. FEATURES 1)Backward compatibility: Wireless USB will be fully backward compatible with the wired USB. current USB drivers and firmware are compatible with wireless USB. 2)Simple, low-cost implementation Preserves the low-cost, ease-of-use model that has made wired USB the interconnect of choice. 3)High performance Wireless USB will provide speeds up to 480 Mbps and in future may exceed 1 Gbps 4)Security It will provide the same level of security as wired USB. Connection-level security will be designed to ensure that devices are associated and that both hosts and devices are authenticated before operation and encryption will be implemented at the application level. 5)An easy migration path Wireless USB will maintain the same usage models and architecture as wired USB for easy migration. 6)Host-to-device architecture It will use a point-to-point connection topology similar to the host-to-device architecture used for wired USB. WUSB APPLICATIONS Wireless USB will make possible next-generation notebook PCs with fewer I/O connectors and a more compact design, as well as digital AV equipment that can wirelessly transmit high- definition video. Typical Home Applications include: ¢ PCs and peripherals ¢ PDAs ¢ External storage devices (HDDs) ¢ HDTVs and STBs ¢ Game consoles ¢ Digital cameras ¢ Digital camcorders And office applications are: ¢ Laptop and notebooks computers ¢ Printers ¢ Scanners ¢ Projectors ¢ Mass storages devices (HDDs) ¢ PDAs ¢ Cell phones ¢ DVD players ¢ MP3 players ¢ CD players ¢ Wireless speakers Full seminar report download: Wireless USB.pdf (Size: 753.83 KB / Downloads: 311)
