Patent ID: 8611364

Claim:
A universal serial bus (USB) control system, comprising: a plurality of antennas configured to transmit and receive a radio frequency (RF) signal; a plurality of wireless USB modules connected to the plurality of antennas, wherein the wireless USB modules are configured to respectively receive different groups of data that form first data via first RF signals received through corresponding antennas while in a receiving mode, and respectively transmit different groups of data that form second data via second RF signals to be transmitted through the corresponding antennas while in a transmitting mode, wherein a number of the different groups of data that form the first data is equal to a number of the wireless USB modules, and a number of the different groups of data that form the second data is equal to the number of the wireless USB modules; and an application layer connected to the plurality of wireless USB modules, wherein the application layer comprises: a controller; a frequency allocating unit configured to allocate different frequency bands to the plurality of wireless USB modules in response to a first control signal received from the controller; a data converting unit configured to convert received serial data into parallel data and convert received parallel data into serial data in response to a second control signal received from the controller; a switching unit configured to set the plurality of wireless USB modules to the transmitting mode or the receiving mode, wherein the plurality of wireless USB modules are configured to transmit the parallel data to a client device while in the transmitting mode, and receive the parallel data from the data converting unit while in the receiving mode; a lookup table configured to store reference channel information corresponding to the plurality of wireless USB modules; and a channel searching unit configured to receive channel information from a client device, and output channel selection information by comparing the channel information with the reference channel information, wherein the controller is configured to select available wireless USB modules from the plurality of wireless USB modules based on the channel selection information.
