Wireless USB host apparatus supporting UWB
First Claim
1. A wireless USB (universal serial bus) host apparatus supporting an UWB (ultra wide band) for connecting a PC (personal computer) and a plurality of wireless USB device through a wireless link, the wireless USB host apparatus comprising:
- a connecting unit for receiving a transmit data and a control signal from the PC and transmitting the data and the control signal to a protocol transforming unit and a controlling unit, respectively, and receiving a received data from a protocol transforming unit and a control signal from a controlling unit, transferring the received data and the control signal to the PC;
a protocol transforming unit for transforming the transmit data inputted from the connecting unit to a media accessing data, extracting a received data from the media accessing data inputted from an UWB physical layer processing unit and transferring the extracted data to the connecting unit, and allocating a media accessing slot to each of the wireless USB devices to share a single wireless channel by the plurality of the wireless USB devices;
a UWB physical layer processing unit for transforming the media accessing data outputted from the protocol transforming unit to an UWB wireless signal and transferring the UWB wireless signal to the wireless USB devices, and receiving an UWB wireless signal from the wireless USB devices, transforming the received UWB wireless signal to media accessing data and outputting the media accessing data to the protocol transforming unit; and
a controlling unit for controlling and managing the connecting unit, the protocol transforming unit and the UWB physical layer processing unit.

Abstract
A wireless USB host apparatus supporting UWB is disclosed. The wireless USB host apparatus allocates a MAS of USB super frame to each of a plurality of wireless USB devices to transmit the real-time audio/video data as well as command data, control data and non real-time data through a single transmission channel. Also, the wireless USB host apparatus uses the ultra wide band to exchange data with the plurality of wireless USB devices to support the data transfer rate of about 53.3 to 480 Mbps, guarantees the QoS and supports transmission of the real-time audio/video data. Furthermore, the wireless USB host apparatus is easy to install, has simple structure and requires low manufacturing cost.
