Portable wireless channel analyzer and wireless channel quality inspection method

Abstract

The invention relates to a portable wireless channel analyzer which not only is convenient to carry, but also can be used for the field inspection of wireless channel quality, and a wireless channel quality inspection method. The portable wireless channel analyzer comprises a shell and a battery. A main controller bi-directionally exchanges data with a certain radio-frequency chip of different frequency bands through an analog switch. The main controller also bi-directionally exchanges data with a touch display screen. The portable wireless channel analyzer and the wireless channel quality inspection method have the advantages that the portable wireless channel analyzer can be used for scanning and analyzing the quality of each corresponding communication channel in the air, is suitable for technicians to check the state of the corresponding wireless channel during field installation of wireless equipment, can help the technicians to arrange the wireless equipment in the field and can realize interaction with users through an intelligent man-machine interaction interface; the technical problem that the technicians cannot evaluate the wireless channel quality in the field is solved, the size is small, the weight is light and the analyzer is convenient to carry; and through experiments, the energy intensity of each working channel in the current environment can be scanned through the radio-frequency chip and the goal of analyzing the channel quality is achieved.

Description

technical field [0001] The invention relates to a portable wireless channel analyzer which is convenient to carry and can detect the quality of the wireless channel on site and a detection method for the quality of the wireless channel, belonging to the field of wireless channel detection equipment manufacturing. Background technique [0002] 1. CN101662328A, name "Portable Ultrashort Wave Frequency Hopping Radio Performance Detector", including a coupler connected to the radio station under test, which couples a small part of the signal emitted by the high-power transmitting radio station and sends it to the radio frequency processing module through its coupling end ; The radio frequency processing module uses a variety of filters to divide the frequency band, and sends the obtained radio frequency signal frequency group to the data acquisition card; the data acquisition card carries out digital processing on the obtained radio frequency signal frequency group; The signal i...

AI Technical Summary

Problems solved by technology

Although the spectrum analyzer can analyze the frequency, bandwidth, transmission power and other information of the input signal, and judge the quality of the channel according to the measured channel energy, it is certainly possible to use a spectrum analyzer to analyze the quality of the wireless channel, but the spectrum analyzer is expensive and expensive. It is bulky and heavy, not easy to carry, and it is very inconvenient for technicians to carry out on-site construction

Moreover, as a professional radio frequency instrument, the spectrum analyzer is complicated to operate, and only professionally trained personnel can operate it.
