What are the methods to improve the interference effect of mobile phone jammer?

  • 2022-04-09

After the mobile phone jammer starts working, the area covered by the interference signal transmitted by it usually ranges from tens of square meters to hundreds of square meters, while the coverage of some high-power jammers will reach thousands of square meters, or the mobile phone signals within a radius of hundreds of meters will be interfered.

However, there will always be some customers who, for various reasons, always want the mobile phone jammer they buy and use to expand the coverage of its jamming signal, or hope to find some ways to greatly improve the jamming effect of the jammer. So, what are the ways to improve the interference effect?

The answer is to look for it from two aspects. The first aspect is to analyze the mobile phone jammer itself. For example, whether the mobile phone jammer is a qualified product of a regular manufacturer, whether its working frequency band is completely correct, and whether the frequency bandwidth is too wide, resulting in the reduction of average output power? Is the frequency band division of mobile phone jammer reasonable? Is there an excessive combination of frequency bands? Is the gain value of the antenna matched with the mobile phone jammer ideal? If the gain of the antenna is only 1-2db, the interference effect will be significantly improved by replacing the antenna with a gain of 3-5db.

The second aspect is to analyze the installation environment and surrounding environment of mobile phone jammer. For example, is the mobile phone jammer wall mounted or placed on the desktop? Is the installation height too high? The usual recommended height is 1.8-2.5m. Or is it too low and placed directly on the ground? This will lead to too many obstacles in the signal transmission path and serious signal attenuation, thus affecting the shielding effect. In addition to these factors, observe and analyze the distribution of surrounding base stations and the installation position of mobile phone jammer. It is recommended to select the transmission path from the base station to the site, which is usually close to the window of the room.
