Does the higher the power of a mobile phone signal jammer, the wider the shielding range?

Does the higher the power of a mobile phone signal jammer, the wider the shielding range?

Does the higher the power of a cell phone signal jammer, the wider the shielding range? Cell phone signal jammer manufacturers explain to you:

signal jammer

Several parameter issues that are helpful for the shielding effect:

1) Output power

The output power of the shielder

Antenna radiation performance (antenna gain, directivity, etc.)

Others

2) How shielding works; now mobile phones all use digital signals, and digital signals have strong anti-interference capabilities. Generally, the effect of using analog signal technology to interfere with digital signals is poor, so digital signals must be used to interfere with digital signals. Digital interference signals with the same power The interference effect of analog interference signals on mobile phones is very different. Signal jammers using digital interference signal technology have lower power and higher efficiency than jammers using analog signal interference technology.

3) Indoors are different from outdoors; the synthesis, attenuation, reflection and other analysis of indoor mobile phone signals and interference signals are 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 good anti-interference effects.

5) The direction of the base station and the direction of the mobile phone shielding area also affect the shielding effect.

6) Shielding distance and radio signal transmission distance characteristics. Now we will briefly discuss the shielding distance based on the attenuation of radio signal transmission in free space. According to the transmission theory formula, every time the radio wave transmission distance is doubled, the signal strength is attenuated by 6db (the signal power is reduced by 4 times).
