In the same environment, there are lots of wifi signals, the same frequency point has more than one signal occupancy, affecting each other, it will cause your own wifi signal quality is very poor, use this assistant, you can easily check which frequency point has more signal, that frequency point is more free, you can adjust your own wifi, switch the frequency point to more empty frequency point, improve the communication quality of your own used wifi. Features: TFT Color Display: 2.4inch TFT color display, supports displaying the wifi signal of all frequencies in the 2.4G band, and the number of wifi occupied by the same frequency point. And it will automatic refresh. Battery Power Display: With battery power display function, the battery power is displayed in the upper right corner of the screen. Long Endurance: Built-in 600mAh lithium battery, working current 160mA, standby time is about 4 hours. Charging Management: Use TYPE-C port for charging, built-in Li-ion charging management circuit. Charging time is about 2 hours. Charging Indicator: 5V charging voltage, when charging, red light means the analyzer is on charging; green light means fully charged. How to use: 1. Press and hold the button to switch on, press and hold again to switch off. 2. Press the button once to starts scanning, press it again to pause scanning. 3. The waveform on the upperline of the screen shows the wifi signal of all frequencies in the 2.4G band, originally, only the strongest one is displayed. However, if there is more than one signal in the same frequency point, it is displayed with a number below the corresponding scale, for example, the number 5 is displayed to indicate that there are 5 wifi occupants in the same frequency point. The waveform at the bottom of the screen corresponds to the waveform of a 5G signal. The interpretation is the same as above. As there are more frequency points for 5G signals, there is no way to have all frequency points marked on the coordinates ruler.
