Building A Noise Database Becomes the Key to Solving The Problem If we can build a database of relevant noise, it could theoretically allow authorities to modify today's regula

The Biggest Problem Is Not Realizing That the Problem Exists The real concern is that no one knows whether outdoor RF noise levels have increased or decreased in recent years. The

How Serious is RF Noise Pollution? RF noise is much higher in cities than in suburbs due to the large and varied collection of electronic devices in cities. Personal computers, rad

When you pass an intersection where a high-speed train passes, the talking phone will immediately short-circuit. When you turn on the electric toothbrush, the picture and sound of

Mobile phones are small in size, low in power, and have no obvious and eye-catching antennas, so many people think that their electromagnetic radiation intensity is lower than that

1. Attenuator Placing an attenuator in the RF input path broadens the dynamic range of the input signal level or adds more input protection to the spectrum analyzer. The attenuator

The spectral distribution of the signal is actually the reflection of the measurement results in the frequency domain. The relationship between the frequency domain and the time do

Some secret you don't know 1. The farther away from the base station, the greater the mobile phone radiation The base station and the mobile phone are like two people talking,

Why are there more and more base stations? The coverage of each base station is limited, and the communication capacity of each base station is also limited. From the perspective o

Base station Where does the signal come from? Of course, it is a communication base station! However, after the base station is built, everyone will worry that the radiation of the

Do you know what radiation is? With the development of science and technology, the application scope of technology products has covered all aspects of our daily life. From the most

3) Atmospheric and industrial radio noise interference is serious. With the development of industrial electrification, the average intensity of radio noise interference radiated by
