Nowadays, mobile phones are all digital signals, and the anti-interference ability of digital signals is very strong. Generally, the effect of using analog signal technology to interfere with digital signals is poor. Therefore, digital signals must be used to interfere with digital signals. The interference effect is quite different. The cell phone jammer using digital jamming signal technology has lower power and higher efficiency than the jammer using analog signal jamming technology.
The synthesis, attenuation, and reflection analysis of indoor mobile phone signals and interference signals is very complicated. Before being shielded, the strength and quality of the local cell phone signal has a great impact on the shielding. Different mobile phones have different effects. Generally, mobile phones with strong ability to receive weak signals may not have good anti-interference effects.
