The present invention relates to a wireless communication apparatus; and, more particularly, to a wireless communication device including an input device function of graphical user interface (GUI) type.
A short-range high frequency wireless communication technology enables the exchange of data between communication and electronic devices and the remote access and control to the communication and electronic devices.
This technology allows the bi-directional communication service to provide and use contents such as a music, a video, a digital data, and so on. The short-range high frequency wireless communication technology includes a Bluetooth, a wireless local area network (WLAN), a wireless personal area network (WPAN), a ZigBee, an ultra wide band (UWB), a near field communication (NFC), a wireless 1394, and etc.
The ultra wide band (UWB) may be used to refer to any radio technology having bandwidth exceeding the lesser of 500 MHz or 20% of the arithmetic center frequency, according to Federal Communications Commission (FCC). Recently, the ultra wide band (UWB) includes a carrier modulation technology for transmitting information spread over a large bandwidth (>500 MHz). Generally, the UWB may be used in the range of 3.1 to 10.6 GHz at a speed of 53.3 Mbps to 480 Mbps or more. The UWB can enables a short-range wireless communication having characteristics of high data rate, longer-range and low power consumption.
When a wireless network builds up based on the UWB, a PCI card including a UWB communication module should be equipped to an internal slot of a desktop computer. In case of a notebook, a PCMCIA card or a CF card is required. Otherwise, the desktop computer or the notebook is coupled to an additional USB dongle including a UWB communication module via a USB port. To insert the additional USB dongle into the USB port is not convenient, like coupling an external device to a computer through a cable adaptor. Further, since an external port such as a USB port should be used for the USB, one of limited ports is of no use for another purpose.
The present invention can provide a wireless communication apparatus comprising an input device function of graphical user interface (GUI) type without using or occupying an external port.
An embodiment of the present invention is to provide a wireless communication apparatus comprising an input device function of graphical user interface (GUI) type without using or occupying an external port.

While the invention will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
Hereinafter, reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below.
Fig. 1 is a conceptual diagram showing a wireless network formation comprising a wireless communication device according to an embodiment of the present invention. Hereinafter, a PC, a notebook, a computer, a desktop computer, and etc., each not including a UWB communication module, are referred as to a host.
Referring to Fig. 1, the wireless communication device 300 including an input device function of graphical user interface (GUI) type according to an embodiment of the present invention is coupled to a USB port of a host 100 not including a UWB communication module. If the wireless communication device 300 is coupled to the host 100, the host 100 can be operated by a graphical user interface without any additional GUI type input device.
The host 100 coupled to the wireless communication device 300 enables data transmission and reception in a wireless communication with a projector 210, a wireless monitor 220, and an audio apparatus 230, each installing each USB communication modules 213, 223, and 233 as well as another host 240 coupled to a wireless communication device according to the present invention. Herein, the data can include various-type data such as a video data, an audio data, a text data, and so on.
Hereinafter, an apparatus which the host 100 coupled to the wireless communication device 300 according to an embodiment of the present invention communicates with, under UWB communication, is referred as to an external device 200. The external device 200 can include various devices such as not only a projector, a wireless monitor, and an audio apparatus but also a printer, a digital camera, a camcorder (video camera recorder), a headphone, a mobile phone, and so on.

Fig. 2 describes UWB frequency spectrum allocation in MB-OFDM.
The UWB is one of optimized solutions to enable a high-speed wireless communication having data rates of the maximum 480 Mbps in a short range of lesser than 10 m.
The Federal Communication Commission (FCC) assigns a frequency band of 3.1 to 10.6 GHz for UWB communication. The FCC power spectral density emission limit for UWB emitters operating in the UWB band is -41.3 dBm/MHz, to minimize an interference occurred between UWB communication and another narrowband wireless communication using an overlapped frequency range.
The WiMedia MBOA alliance suggests Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) for a high data-rate wireless communication. In MB-OFDM, a frequency spectrum is split into 14 bands, each having a range of 528 MHz. As shown in Fig. 2, there are six band groups binding two or three bands in the frequency spectrum. In an embodiment of the present invention, a wireless communication device is for using UWB technology to wirelessly transmit a video data in a short range.
Fig. 3 is a block diagram depicting a wireless communication apparatus according to an embodiment of the present invention.
As shown, the wireless communication apparatus 300 can be coupled via USB port, and etc. of the host 100. Fig. 3 describes an embodiment in a case when the wireless communication apparatus 300 is coupled to the host 100 via USB port.
Referring to Fig. 3, the wireless communication apparatus 300 includes a UWB communication block 310, an input device 320, a USB hub controller 330, and a USB cable 340.
The UWB communication block 310 enabling the exchange of data between the host 100 and the external device 200 through UWB communication comprises a sign-on block 311, a UWB communication controller 312, an information storing unit 313, a base band processing unit 314, an RF transmitter315, a band pass filter 316, and an antenna 317.
The sign-on block 311 outputs a start signal to the UWB communication controller 312 in response to user's input. Herein, the start signal allows the UWB communication controller 312 to explore the external device 200 including a UWB communication module for USB communication with the host 100. According to an embodiment, a UWB communication block does not include a sign-on block. If there is no sign-on block inside the UWB communication block, the UWB communication controller 312 starts to explore the external device 200 when the wireless communication apparatus 300 is coupled to a USB port.
The UWB communication controller 312 controls course of data transmission or data signal reception. The UWB communication controller 312 receives the start signal outputted from the sign-on block 311, explores the external device 200 installing a USB communication module, establishing a UWB wireless communication between the host 100 and the explored external device 200, and controlling the UWB wireless communication in a short range. If a predetermined event is occurred from the external device 200 after the UWB communication controller 312 is wirelessly connected to the external device 200, the UWB communication controller 312 allows the base band processing unit 314 or the RF transmitter315 to receive data from the external device 200 or transmit data from the host 100 to the external device 200.
The information storing unit 313 stores a profile for supporting various UWB applications. When data is delivered from the external device 200 to the host 100, the RF transmitter 315 performs down-conversion from a RF signal inputted via the antenna 317 into an in-phase or quadrature-phase signal and outputs the in-phase or quadrature-phase signal to the base band processing unit 314. The base band processing unit 314 converts the in-phase or quadrature-phase signal into a digital signal. Also, the base band processing unit 314 performs another digital signal processing operation such as an error- restoration using various algorithms according to a wireless channel circumstance.
In a case that the host 100 transmits data to the external device 200, the base band processing unit 314 converts a digital signal corresponding to the data into an analog in-phase or quadrature-phase signal and outputs the analog in-phase or quadrature-phase signal to the RF transmitter 315. The RF transmitter 315 performs up-conversion from the analog in-phase or quadrature-phase signal to a RF signal and outputs the RF signal to the band pass filter 316.
The band pass filter 316 receives the RF signal from the RF transmitter 315 and passes the RF signal within frequencies in a band used for UWB communication to transmit a band-passed signal to the external device 200 via the antenna 317. Herein, the antenna 317 can be arranged to a side of the wireless communication apparatus 300, which is opposite to a side held by user's hand.
The input device 320 configured to perform an input device function of graphical user interface (GUI) type to the host 100 comprises a movement detection sensor 321, a coordinate calculating unit 322, an interface unit 323, and a control signal processor 324.
The movement detection sensor 321 detects movement of the wireless communication apparatus 300. For example, the movement detection sensor 321 can include an optical device configured to use a light for sensing the movement. Not only the optical device but also various devices which can detect its movement can be applied to the wireless communication apparatus 300. The coordinate calculating unit 322 receives a signal corresponding to the movement of the wireless communication apparatus 300, which is sensed by the movement detection sensor 321, performs a coordinate conversion about the signal, and outputs the result including position information in a domain of two plots, i.e., X axis and Y axis, to the control signal processor 324.
The interface unit 323 comprises one or more buttons, generating a signal according to which button physical or electrical input is delivered through and outputting the signal to the control signal processor 324. The control signal processor 324 receives the result of coordinate conversion from the coordinate calculating unit 322 and the signal outputted from the interface unit 323 and controls the movement of cursor in a screen of the host 100.
The USB hub controller 330 provides a USB driver to the host 100 if the wireless communication apparatus 300 is coupled to the host 100, selectively routes data outputted from the UWB communication block 310, and interfaces between the host 100 and both the UWB communication block 310 and the input device 320. The USB cable 340 couples the USB hub controller 330 to the host 100 via a USB port.
