Description
Technical field
The invention belongs to wireless network hardware equipment technical field, relate in particular to a kind of Wireless Telecom Equipment that is applicable to the technology such as spread spectrum communication and WLAN (wireless local area network) or digital cordless phones and wireless automatic identification.
Background technology
Existing low price wireless frequency expansion and WLAN (wireless local area network) pipeline equipment mostly are low-power short distance indoor application.When for outdoor length apart from time, due to the insertion loss of high frequency cable, through-put power can significantly decline.Use traditional two-way amplifier can improve through-put power and receiving sensitivity.But inconsistent due to the technical specifications such as wireless network card power output of different manufacturers and performance, and indoor uncertain to outdoor cable length and specification while specifically setting up, traditional gain index without line amplifier must strictly be controlled, otherwise easily cause because the too low power output causing of gain is inadequate, affect transmission range, or cause because the too high output signal distortion causing of gain affects signal transmission quality and causes unnecessary spectral interference.Above-mentioned reason makes without the producing and selling of line amplifier and very not convenient is installed.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of prior art, a kind of Intelligent amplifier of wireless network that possesses power magnitude monitoring and automatic gain control function is provided, can be under different input signal conditions, intelligentized reduction signal noise, control signal transmission quality, guarantee maximum transmitting power, effectively extend signal transmission distance, bring great convenience to production, the operation and maintenance of two-way amplifier.
For achieving the above object, technical scheme of the present invention is, an Intelligent amplifier of wireless network, for for connect the two-way amplifier of antenna and direct current injector by feeder line, is characterized in that: in described two-way amplifier, comprise power monitoring module and power sensor; Described power monitoring module is connected to a variable attenuation gain control module, and described variable attenuation gain control module output is linked into emission amplifier module, and the output of described emission amplifier module is linked into a switch module.
As preferably, when described two-way amplifier is during in receiving mode, described switch module is input to band pass filter and low noise amplifier by wireless signal, and described low noise amplifier is transferred to output signal another switch module again.
As preferably, when described two-way amplifier is during in emission mode, described switch module is to described antenna transmission wireless signal.
The technology of the present invention is applied relevant with point-to-point with being connected of point-to-multipoint at WLAN (wireless local area network), WLAN (wireless local area network) ring and wireless internet accessing, radio modem with Time division duplex.Intelligent amplifier of the present invention, the basis that utilizes input signal to control as its gain, if i.e. input over just increases certain decay, makes the last power output of amplifier remain on preset range, avoids distorted signals.If input signal is too small, just increase the gain of amplifier, the last power output of amplifier is still remained in preset range.
The present invention, at beneficial effect, in general, is the high-quality transmitting of realizing wireless signal, brings great convenience to production, the operation and maintenance of amplifier.Specifically enumerate, also comprise:
1, make two-way amplifier in varying input signal situation, guarantee that amplifier is operated in optimum state, performance optimal performance;
2, provide loose operation parameter, can meet two-way amplifier and work in hardware condition and environment for use widely;
3, the two-way amplifier framework of standard is provided, makes the installation and maintenance of two-way amplifier become convenient more economically;
4, specific implementation a kind of brand new technical scheme of automatic control two-way amplifier gain;
5, can maintain the constant output of two-way amplifier, guarantee minimum distorted signals.
