Example Embodiment

[0015] see figure 1 , A wireless network smart amplifier, which is a two-way amplifier used to connect an antenna and a DC injector through a feeder. The two-way amplifier includes a power monitoring module, a power sensor, an amplitude monitoring module, a transceiver control module, and a power supply module. The module is connected to a variable attenuation gain control module, the output of the variable attenuation gain control module is connected to the transmitting amplifier module, and the output of the transmitting amplifier module is connected to a switch module 1. When the two-way amplifier is in the receiving mode The switch module one inputs the wireless signal to the bandpass filter and the low noise amplifier, and the low noise amplifier transmits the output signal to another switch module two, and then to the DC injector, when the two-way amplifier When in the transmitting mode, the switch module always transmits wireless signals to the antenna.

Abstract

The invention discloses a wireless network intelligent amplifier, belongs to the technical field of wireless network hardware equipment, and in particular relates to wireless communication equipment which is applicable to the technologies, such as spread spectrum communication and wireless local area networks or digital wireless telephones and wireless automatic identification. 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...
