Does a mobile phone signal jammer have a greater shielding range if the jammer is more powerful?

Several parameters that are helpful for mobile phone signal shielding effects:

1. Output power

①The output power of the shielder

②Performance of antenna coverage (antenna gain, directivity, etc.)

③Others

2. How shielding works:           signal jammer

Nowadays, mobile phones use digital signals, and digital signals have strong anti-shielding capabilities. Generally, the effect of shielding digital signals using analog signal technology is poor, so digital signals must be used to shield digital signals. Digital shielding signals and analog shielding signals of the same power have a negative impact on mobile phones. The shielding effect is very different. The jammer using digital signal shielding technology has lower power and higher efficiency than the jammer using analog signal shielding technology.

3. Indoor and outdoor are different:

The analysis of synthesis, attenuation, and reflection of indoor mobile phone signals and shielded signals is very complex.

4. Before shielding, the strength and quality of local mobile phone signals have a great impact on shielding. Different mobile phones have different effects. Generally, mobile phones with strong ability to receive weak signals may not necessarily have a good anti-shielding effect.

5. The direction and distance of the signal source and the direction of the mobile phone shielding area also affect the shielding effect.
