How much does a small signal jammer cost?

rice of signal jammers varies greatly depending on their power and range of use, ranging from a few hundred dollars to tens of thousands of dollars. Typically, a small signal jammer can be purchased in the market for a few hundred dollars.

This particular type of compact signal jammer serves the purpose of safeguarding children from becoming overly dependent on mobile phones. Additionally, it can be employed in small dormitories and classrooms to effectively disrupt mobile phone network signals, thereby deterring phone communications and restricting Internet access.Furthermore, the utilization of a high-power signal jammer within a residential setting will inevitably disrupt nearby communication systems, thereby impeding the regular usage of mobile phones by neighboring individuals and potentially leading to grievances. Hence, it is advisable to employ compact signal cellphone jammer within households, dormitories, and modest classrooms.

This device has the capability to efficiently disrupt all mobile phone signals (CDMA, GSM, DCS, PHS, 3G, 4G, 5G) as well as WIFI (WLAN), Bluetooth/2.4G communications, and wireless networks (Facebook, Instagram, etc.) within a range of 10 meters.

1. Why do some mobile phones still have signal indications when the signal jammer is working?

It is merely an illusion, as the mobile phone is currently unable to establish communication. Upon pressing the activation button, you will notice the absence of any signal indication on the device's signal indicator.

2. Will the wireless signal jammer interfere with the normal operation of other electronic devices?

The reason for this is that the wireless gsm signal jammer emits an electromagnetic signal that is entirely within the designated working frequency band of the country. Consequently, it solely disrupts wireless electromagnetic signals within the shielded area. Moreover, this signal remains relatively stable and does not interfere with other electronic devices.

3. Is the mobile phone signal jammer harmful to the human body and mobile phones when it is working?

Rest assured that the electromagnetic signal emitted by the mobile phone signal jammer is extremely faint and adheres to environmental regulations. Extensive tests have demonstrated that this signal intensity poses no threat to the human body. Simultaneously, the mobile phone signal jammer solely obstructs the forward signal of the mobile phone, preventing it from establishing contact with the base station, thereby ensuring no harm is inflicted upon the mobile phone itself.

4. Is there any difference in the operating distance of wireless signal jammers when used indoors and outdoors?

There exists a distinction between the signal strength experienced outdoors and indoors, with the former generally being stronger. Consequently, the effectiveness of outdoor shielding is relatively low. In a precise sense, the operational range of a wireless signal jammer, whether utilized indoors or outdoors, is influenced by the electromagnetic conditions of the shielding location and its surroundings. This includes factors such as the proximity between wireless signal transmitting equipment outside the premises and wireless communication devices within the premises, as well as their respective placements.

5. Does the mobile phone signal jammer have the same effect on mobile phones and 2.4GHz wireless communication equipment?

The efficiency of wireless communication signal transmission is contingent upon the distance separating the transmitting equipment from the receiving equipment.The transmission distance of 2.4GHz wireless communication equipment is constrained by national standards, resulting in a significantly shorter range compared to base station communication signals. However, when the transmitting and receiving equipment are equidistant, the shielding range of 2.4GHz wireless communication equipment is marginally greater than that of mobile phones.If the base station is not located far from the shielding place, the opposite scenario will arise in the case of a weak signal.

6. After the mobile phone signal jammer has been working for a period of time, the heat sink of the device will heat up. Will working for a long time damage the machine?

The heating up of the heat sink in the mobile phone signal jammer is a common occurrence. Our design incorporates high-performance aluminum alloy heat sinks with excellent thermal conductivity to effectively dissipate the heat generated during operation. This ensures the stable and prolonged functioning of the machine without any damage caused by the heat generated from the heat sink.
