the USB has conquered the PC and PC
peripheral markets and captured a significant share of the consumer electronics market since its introduction in 1996. Upcoming is a Wireless USB standard that
will provide high-speed connectivity over a distance of 10 meters and data rate of 480
Mbps. It is capable of high-bandwidth multimedia streaming and data transfers.Also
it will maintain the host-to-device architecture, usage models, and
simplicity of wired USB to enable easy migration from wired to wireless USB solutions.
UWB: THE UNDERLYING TECHNOLOGY
The ultra-wide band (UWB) radio is the The basic transport mechanism for Wireless USB. Multiband OFDM Alliance (MBOA)
and the WiMedia Alliance has been perfecting this technology.
UWB R ADIO LAYER:
The UWB transmits short, fast, low-power wavelets of energy over a very wide band of frequencies. UWB communications in the 3.10 to 10.6 GHz slice of the radio spectrum has been legalised. a wireless USB
cluster can communicate on the same channel as another cluster in proximity. The radio circuitry can be implemented in cost-effective
CMOS.
THE CONVERGENCE LAYER
This layer serves as an interface between the UWB radio layer and UWB-based applications.and allows allows multiple applications to share a single radio. The UWB platform is first to be utilised by WUSB.
WUSB CLUSTER TOPOLOGY
These use a simple hub and spoke topology, with point-to-point connections between the host and the devices connected to it. The host acn connect to a maximum 127 devices. It initiates and schedules data transfers to the devices in the cluster, allotting time slots and bandwidth to each connected device.
