INTRODUCTION
Wireless USB is a wireless technology which enables the high speed computer peripheral interface, USB, wireless. It is a wire replacement of existing USB technology using a Multi Band Orthogonal Frequency Division Multiplexing radio technique.
Wireless USB interest group was formed in 2004. It is the first high speed personal interconnect. The physical layer is standardized under IEEE 802.15.3 PHY. Today it is in the developing stage. The major WUSB promoters are HP, Intel, Microsoft, NEC Philips, & Samsung
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 interconnect
• USB devices
• USB host
The USB interconnect
The USB interconnect is the manner in which USB devices are connected to and communicate with the host. USB devices
Wireless USB devices are one of the following:
Functions, which provide capabilities to the system, such as a printer, a digital camera, or speakers
Device Wire Adapter, which provides a connection point for wired USB
devices.
USB Host
There is only one host in any USB system. The USB interface to the host computer system is referred to as the Host Controller. Host controllers are typically connected to PCs through an internal bus such as PCI. The Host Controller may be implemented in a combination of hardware, firmware, or software.
Wireless USB has an advanced power management system which consumes very low power. The power management system is based on Tx/Rx system. It also supports an advanced encryption system in order to ensure the secure connection between the host and device.
