The mobile phone jammer can block various frequencies. The equipment is usually divided into low-end and high-end types. High-end jammers block all frequencies at once, while low-end jammers block only one frequency. Let's take a look at the three subcircuits of a cell phone jammer. If you're considering buying one, it's worth knowing the differences between the three devices.


Low-end jammers only block one frequency at a time



  • High-end cell phone jammers block multiple frequencies at once, while low-end models block only one frequency.

  • These low-end jammers are usually much smaller and can fit in the palm of your hand.

  • They only block one frequency at a time and are less expensive than their higher-end counterparts.

  • They also only cover a small area. They can significantly reduce cell phone calls compared to high-end jammers.




8 Bands Jammer


range of cell phone jammers


Cell phone jammers range from low-power personal jammers to large devices that create blind spots up to a mile long. The power of the jammer will also depend on its location. Hills and buildings block the signal, so low powered devices may only interfere with calls within 30 feet. But higher powered models were able to create a cell-free zone the size of a football field. Jammers are designed to interfere with digital and analog mobile phones.


To interfere with cell phone signals, it is important to use equipment that operates on the correct frequency. Different cellular systems use different frequencies and therefore have different ranges for interfering devices. GSM uses the 900 MHz frequency band in Europe and Asia and 1900 MHz in the US. But there are jammers that work on all frequencies and these devices are equally effective on GSM, PCS and Nextel systems. A jammer that blocks analog cell phone signals is just as susceptible to interference as its counterparts.


signal strength for gsm blocker


A cell phone signal blocker is a device that blocks cell phone signal reception. It can be used to deter or stop espionage by detecting its signature. Signal blockers are generally box-type, with a single output power of 15W. Such devices are segmented to only interfere with the downlink. Its soft start circuit design prevents sparking and provides good working stability.


transmission power of gsm interceptor


A gsm blocker is an electronic device that blocks signals from mobile phones. The device transmits at a lower power level than other mobile devices to protect the human body and reduce interference. This power level is regulated by local regulators. Depending on the type of equipment used, the power level can range from zero to a few dB or more. However, these factors can only be used to determine the effectiveness of the device.


distance between base station and gsm blocker


The distance between the base station and the phone is key to successfully jamming the signal. There are two main types of signals: SMS and ortungscodes. While SMS are an alternative to signaling channels, they are less efficient. The two types of signals have different amounts of information, and the distance between the base station and the phone is usually greater. To prevent interference, the phone should be placed 200 to 300 meters from the base station.


A cell phone jammer works similar to a home stereo. Signals are sent from cell phones to cell towers, which distribute the workload to specific areas. The jamming device is placed between the two towers and simulates cell phone signals by sending radio frequencies to the same frequencies as cell phones. Unlike a phone signal, this one is strong enough to block the signal.


High-end jammer blocks all frequencies at once


Cell phone jammers are powerful devices that interfere with wireless signal transmissions. These devices work by simulating legitimate phone signals on the same frequency as cell phones, preventing them from making or receiving calls. Jammers operate on different frequencies, and some of them block all jammers at once. They are a great solution for individuals who want to eliminate annoying prank calls and avoid being harassed.


High-end devices are capable of completely blocking multiple cellular networks at once. The best jammers are able to block several different frequencies at once, which makes them very effective against both the cell phone network and the caller. Some models can even be programmed to jam specific frequencies. High-end jammers will be able to block all frequencies at once and can also jam dual or triple mode phones.
