A cell phone jammer is a device that can block a mobile phone signal. An activated cell phone jammer can prohibit phone communication within its working distance. That’s why it is also called a phone blocker. Cell phone jammers come in different ranges and can jam different frequencies. The most common phone frequencies you can find are GSM, CDMS, 3G, and 4G. The all-in-one phone blockers can block them all. Some of our phone jammers can block 5g signal as well.
All signal jammers rely on the jamming signal sent to the surrender to disrupt the target radio waves. Therefore, when we are talking about the range, it means the maximum distance the jamming signal can reach. The typical range of a portable jammer is about 25 meters and 40 to 80 meters for desktop jammers.
Most cell phone signal jammers can also jam other frequencies, such as wifi or GPS. But if you don’t need such functions, you can turn them off by removing the specified antennas. Since the output power of the jammers is low, they can work silently and do not negatively impact the human body.
Portable cell phone jammers
Portable cell phone jammers are the most widely used. Their small size can fit in your pocket smoothly. The working distance range from 10 to 25 meters, which is enough for most applications. The portable jammers have a built-in battery that can support up to 2 hours of work, which is enough in most cases. The biggest benefits you can get from the portable jammer are their easy to carry and lightweight design. You can put it in your car or take it to your bag during your business trip to protect yourself from many threats, like overhearing, stolen digital data, etc.
Desktop cell phone jammers
Desktop cell phone jammers tend to have larger jamming ranges. They usually come in 50 to 80 meters. If you are going to use it in the offices and meeting rooms, or in any places you won’t move it after the installation, you should consider a desktop version as they are more powerful. The high-power desktop jammers can ensure there are no dead-zone within their range. That means more stable outcomes.
