Abstract
The utility model discloses a kind of wireless transceiver based on USB (universal serial bus), relate to field of wireless transmission, particularly relate to a kind of portable high-speed wireless transceiver of USB3.0 interface, comprise USB3.0 interface component, interface controller, modulation /demodulation module, wireless transmission reception module, built-in aerial.For when not carrying out larger change to host computer and display device hardware, efficiently realize regular display easily become radio display by setting up USB interface peripheral hardware, common touch display becomes high-performance low-power-consumption Pad, compensate for the deficiency that regular display does not support Wireless Display.Compared with prior art advantage is easy to use, without the need to extra power supply, exquisite portable, makes display device support user interactions as Pad, low owing to realizing cost, is convenient to promote the use of.
Description
Technical field
The utility model relates to field of wireless transmission, particularly relates to a kind of portable high-speed wireless transceiver of USB3.0 interface.
Background technology
USB interface becomes the whole world at present and adopts interface the most widely under leading the supporting of the industries such as Microsoft and Intel, and its latest specification is USB3.0, and maximum transmission bandwidth is up to 5.0Gbps.In market, relative technological products has USB to turn HDMI converter, the external display card of USB3.0 interface, supports the AOC E2251FWU display etc. of USB3.0 interface, the high speed development along with USB3.0 technology can be predicted, USB3.0 interface will become video card, display, the standard configuration interface of computer main board etc.
The impact that wireless technology brings is incontrovertible.Nowadays every day, nearly 150,000 people became new wireless user, and the number of wireless users in global range is now more than 200,000,000.Hypervelocity transmission is the developing direction of wireless technology, and as WHDI technology, WiGig tri-is wireless technology frequently, and its speed of the NoLA communication technology is all more than 3Gbps.The high speed development of Radio Transmission Technology and people, to the pursuit of convenience, have expedited the emergence of wireless HDMI transmitting device, the similar products such as radio display.
2010, apple iPad has started panel computer upsurge in the whole world, current Pad is seen everywhere especially, but the handling property of desktop computer still has gap relatively, so that some large softwares very high to hardware requirement cannot smoothly on Pad run, even if the Pad heating that the computing that can run that overload easily causes original radiating effect just bad increases sharply, affect its life-span.Can have a low price, performance is intrepid, and the long-endurance Pad of low-power consumption is good problem to study.
Forming high-performance Pad by low cost high-speed radio transceiver connection host computer and touch display is innovation place of the present utility model, has also filled up the blank in this field.The development of above-mentioned background technology---USB3.0, the development of hypervelocity wireless transmission, then lay a good foundation for filling up this blank, the not yet universal this programme of current wireless price display unit costliness then can simple realization Wireless Display function, and it is also its shortcoming that wireless HDMI transmitting device cannot carry out data interaction except volume very much not Portable belt.
Summary of the invention
The deficiency that the utility model exists for above-mentioned prior art, propose a kind of wireless transceiver based on USB (universal serial bus), for when not carrying out larger change to host computer and display hardware, peripheral hardware is assisted by setting up USB, efficiently namely realize regular display easily becomes radio display, common touch display becomes high-performance Pad, compensate for the deficiency of the display not supporting Wireless Display function.It is formed primarily of the transceiver be inserted on host computer USB3.0 interface and the transceiver be inserted on touch display.The method that the high processing host part of the large power consumption of operand and display section separate allows common touch control display become the high-performance low-power-consumption lasting Pad that continues a journey becomes possibility.
The utility model pin solves the problems of the technologies described above and adopts following technical scheme:
The design feature of a kind of wireless transceiver based on USB (universal serial bus) of the utility model comprises:
The high-speed radio transceiver of a pair USB3.0 interface, the high-speed radio transceiver of described USB3.0 interface comprises USB3.0 interface component, interface controller, modulation /demodulation module, wireless transmission reception module, built-in aerial.
Above-mentioned a kind of wireless transceiver based on USB (universal serial bus), is characterized in that: the data stream that described transceiver sends can comprise audio frequency, video, human-machine interaction data simultaneously.
Compared with the prior art, the utility model beneficial effect is embodied in:
Based on the most widely used USB3.0 interface, low cost realizes Wireless Display function; Large power consumption high-performance main frame is independently-powered with display interactive device, the Pad making display device become flying power greatly to promote by wireless transceiver; Transceiver is directly powered without the need to other voltage adapters by USB3.0 interface.
