Description
Technical field
The utility model relates to wireless communication technology, cdma wireless login technique and the Bluetooth technology of particularly utilizing USB (universal serial bus) to communicate by letter with PC.
Technical background
Bluetooth (Bluetooth) is the short distance radio communication standards of being joined together to develop by mobile operator and mobile computing company, is used for designing setting up a kind of small-sized, economic, short-range Radio Link between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook etc.For these bluetooth equipments are communicated by letter with the PC of no Bluetooth function easily, a kind of Bluetooth adapter of universal serial bus technology and Bluetooth technology that utilizes arises at the historic moment.Little, the no complex drive mechanism of Bluetooth adapter volume, easy to carry can be set up communication link for other bluetooth equipments and PC easily.
CDMA (Code Division Multiple Access) is the abbreviation of CDMA.CDMA can provide the transfer rate up to 2Mbit/s.The application of getting online without being tethered to a cable by mobile phone or notebook computer in being particularly suitable for moving.The cdma wireless card of surfing Internet that is used for notebook computer at present adopts pcmcia interface mostly, and this cdma wireless card of surfing Internet is of limited application, and can not be used to not have the common desktop computer of pcmcia interface.
Usb bus has become the most general peripheral hardware connecting bus, and it has simply, serial transmission, and antijamming capability waits outstanding advantage by force.Along with the equipment that uses USB interface is more and more, not enough situation often appears in USB interface of computer, at this moment just can use usb hub (USB HUB) to expand USB interface of computer.
Bluetooth adapter and cdma wireless card of surfing Internet all have a wide range of applications.In order between bluetooth equipment and PC, to set up communication link, need to use Bluetooth adapter.For mobile Internet access, need to use the cdma wireless card of surfing Internet.And now need to use the occasion of above two kinds of equipment a lot of simultaneously, but they are separate equipment, have so both taken two USB interface, give again to use and have brought inconvenience.
The content of invention
Technical problem to be solved in the utility model is: usb hub (USB HUB), Bluetooth adapter and cdma wireless card of surfing Internet are integrated formation bluetooth CDMA universal serial bus concentrator, it can also realize the near radio data transmission with other bluetooth equipment except possessing high-quality remote CDMA data-transformation facility.Like this, both expand USB interface of computer, can realize data sharing between various computing machine or handheld device again.And have both some advantages that the three is arranged simultaneously, and as: it is little, easy to carry, easy to use etc. to need not complex drive mechanism, volume.
The technical solution adopted in the utility model is such, and promptly a kind of bluetooth CDMA universal serial bus concentrator comprises bluetooth USB adapter, cdma wireless card of surfing Internet and usb hub; It is characterized in that: bluetooth USB adapter is connected with the peripheral hardware USB interface of usb hub by its USB interface, the cdma wireless card of surfing Internet is connected with the peripheral hardware USB interface of usb hub to the USB interface conversion chip by serial ports, bluetooth USB adapter, usb hub and cdma wireless card of surfing Internet encapsulation one, what wherein usb hub had is used to connect computing machine or/and the USB interface of peripheral hardware exposes to housing or drawn by lead.
The good effect that the utility model has owing to described structure is conspicuous, being about to usb hub, Bluetooth adapter and cdma wireless card of surfing Internet integrates, bluetooth USB adapter is connected with the peripheral hardware USB interface of usb hub by USB interface, and the cdma wireless card of surfing Internet is connected with the peripheral hardware USB interface of usb hub to the USB interface conversion chip by serial ports.By usb hub (USB HUB) be used for the interface finishing device of compunication and PC between be connected.USB HUB can also be used to connect computing machine for other equipment provide USB interface simultaneously.Do not have complex drive mechanism in the structure, it is little, easy to carry, easy to use to have a volume, characteristics such as of many uses.
