Description
Technical field
The utility model belongs to 3G online and WLAN share technique field, and particularly a kind of many people share the portable broadband wireless device of getting online without being tethered to a cable.
Background technology
Most of radio network gateways in the market, major function only play the purpose that lets multiple computers share a broadband line online.Now, network access not only was confined to fiber broadband along with mechanics of communication is showing improvement or progress day by day, and also had 3G wireless, wireless Internet access modes such as wifi focus.Just can't use the 3G mode to insert the Internet with common wireless router like this.
And use common 3G card of surfing Internet, and can only let independent PC online, can not realize that a plurality of PCs share online, and general wireless Internet card uses is the power supply that PC is supplied with, can't operate as normal once shutting down, do not have flying power.
The utility model content
The technical problem that the utility model solved is to provide a kind of many people to share the portable broadband wireless device of getting online without being tethered to a cable, and makes a plurality of users share same 3G equipment for surfing the net.
The technical solution that realizes the utility model purpose is: a kind of many people share the portable broadband wireless device of getting online without being tethered to a cable; Include OLED display module, USB interface realization module, power management module, keyboard module, SD storage card realization module, TD module realization circuit, gsm module realization circuit, WIFI module realization circuit and master controller; Said Organic Light Emitting Diode display module is connected with master controller; It is shown; USB interface realization module is connected with master controller and for it USB interface is provided; The keyboard module is connected with master controller, and for it provides the signal input, the SD storage card realizes that module, TD module realize that circuit, gsm module realization circuit, WIFI module realize that circuit also all is connected with master controller; Power management module is connected with above-mentioned module, for it provides power supply.
The utility model compared with prior art, its remarkable advantage is: 1) the utility model can solve the problem that many people share 3G network, makes many people use same equipment for surfing the net wireless access the Internet; 2) the utility model internal battery, independent battery can guarantee losing continuation of the journey work under the situation of external power source; 3) the built-in storage card of the device of the utility model also can be used as storage card and use the Ipad user's that fits especially demand in the time of online; 4) device that uses this utility model exclusively enjoys low that overall rate that the 3G network interface card produces come than a plurality of users, has saved user's expense.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is that many people of the utility model share the portable broadband wireless apparatus structure sketch map of getting online without being tethered to a cable.
Fig. 2 is antenna interface circuit and radiofrequency signal in many people of the utility model portable broadband wireless device of share getting online without being tethered to a cable, GSM signal receiving circuit.
Embodiment
In conjunction with Fig. 1; A kind of many people of the utility model share the portable broadband wireless device of getting online without being tethered to a cable; Include OLED display module, USB interface realization module, power management module, keyboard module, SD storage card realization module, TD module realization circuit, gsm module realization circuit, WIFI module realization circuit and master controller, said Organic Light Emitting Diode display module is connected with master controller, and it is shown; USB interface realization module is connected with master controller and for it USB interface is provided; The keyboard module is connected with master controller, and for it provides the signal input, the SD storage card realizes that module, TD module realize that circuit, gsm module realization circuit, WIFI module realize that circuit also all is connected with master controller; Power management module is connected with above-mentioned module, for it provides power supply.Said master controller is a master control PXA920 chip.Said master controller also can be selected the CPU based on the armv5 instruction set of Marvell sheeva pj1 framework for use.Said master controller also can be single-chip processor.
Antenna interface circuit and radiofrequency signal, GSM signal receiving circuit in the shared portable broadband wireless device of getting online without being tethered to a cable of many people of the utility model.
The integrated emission of coupler (Tx) and reception (Rx) front-end module (FEM) in the portable broadband wireless device that many people of the utility model share to get online without being tethered to a cable.Support four GSM, GPRS and EDGE application frequently.This device provides the complete Tx path that outputs to antenna from transceiver, integrated power amplifier (PA), Tx harmonic filter and coupler, and pseudo-morphic high electron mobility transistor (pHEMT) RF switch of high linearity, low insertion loss.This FEM can realize the solution of a complete transmitting terminal voltage controlled oscillator (VCO) to antenna and antenna to receiving terminal surface acoustic wave (SAW) filter.
The used CPU of the utility model is the CPU based on the armv5 instruction set of Marvell sheeva pj1 framework.The bus extender sketch map; Utilize industrial standard I2C, SMBus or SPI interface to simplify the expansion of I/O mouth; When microcontroller or chipset do not have enough I/O ports; Or when system need adopt far-end serial communication or control, the GPIO product can provide extra control and function for monitoring, and bus extender abbreviates GPIO as.
The power management module circuit; It is the power management scheme that a kind of height is integrated, be directed against portable use; Being about to some types of discrete power management devices of tradition is incorporated within the single encapsulation; Can realize higher power supply conversion efficiency and more low-power consumption like this, and package count still less is to adapt to the plate level space that dwindles.
Audio frequency multimedia digital signal coder/decoder circuit, it utilizes the function of acp chip group and the function that peripheral analog machine is realized audio card/Modem jointly.
