The wireless network intelligent amplifier is a bidirectional amplifier which is used for connecting an antenna and a direct-current injector through a feeder line, and comprises a power monitoring module and a power sensor, wherein the power monitoring module is connected to a variable attenuation gain control module; the output of the variable attenuation gain control module is connected to a transmitting amplifier; the output of the transmitting amplifier is connected to a switch module. The wireless network intelligent amplifier has the benefits that high-quality and reliable transmission of wireless signals is realized, and great convenience is brought to the production, the use and the maintenance of amplifiers.

Description

technical field [0001] The invention belongs to the technical field of wireless network hardware equipment, and in particular relates to a wireless communication equipment suitable for technologies such as spread spectrum communication, wireless local area network, digital wireless telephone, and wireless automatic identification. Background technique [0002] Most of the existing low-cost wireless spread spectrum and wireless local area network equipment are low-power and short-distance indoor applications. When used for long distances outdoors, the transmission power will be greatly reduced due to the insertion loss of high frequency cables. The transmission power and reception sensitivity can be improved by using a conventional bidirectional amplifier. However, due to the inconsistency in technical specifications and performance of wireless network cards from different manufacturers, as well as the uncertainty of the cable length and specifications from indoor to outdoor...

Problems solved by technology

However, due to the inconsistency in technical specifications and performance of wireless network cards from different manufacturers, as well as the uncertainty of the cable length and specifications from indoor to outdoor during specific erection, the gain index of traditional wireless amplifiers must be strictly controlled, otherwise it is easy to cause due to gain. If the output power is too low, the output power is not enough, which will affect the transmission distance, or the output signal will be distorted due to the high gain, which will affect the quality of the transmission signal and cause unnecessary spectrum interference

The above reasons make the production, sales and installation of wireless amplifiers very inconvenient
