Cell phones have experienced a remarkable surge in popularity over the past several decades. A study conducted in October 2020 indicates that there are well over 380 million cell phones in use in the United States, with this figure steadily increasing. The usage of cellular phones is comparably widespread in Europe as well.
The ability to connect with anyone at any time is a convenience that is often underestimated by many individuals. However, mobile phones also harbor a darker side that numerous business owners have had to confront through difficult lessons learned.
The Dark Side of Cell Phones
Mobile phones are effective and efficient communication tools; however, their use can be inappropriate at times. In various public settings, such as theaters, restaurants, concerts, funeral homes, and churches, some individuals do not recognize the necessity of putting their devices away. This behavior can be socially unacceptable, leading to frustration among those who observe the established norms, especially when there are clear indications against cellular usage.
Moreover, the potential for the cell phone to serve as a detonating device for more malicious intents has led to the formation of our IED jammer category, aimed at protecting lives and preventing tragic outcomes.
A viable approach to promptly and safely eliminate these concerns is through the use of a cell phone jammer. Acquiring knowledge about the operation of signal jamming on wireless devices will allow for a greater understanding and appreciation of their overall value.
Basics Of The Cell Phone Blocker
Effectively disrupting a cell phone signal is comparable to jamming any other type of mobile radio communication using a standard signal blocker. It is important to remember that wireless devices function by communicating directly with their designated service networks through base stations or towers, which segment cities into smaller areas called cells.
While driving down the street, a mobile phone user experiences the signal being relayed between towers, similar to a football being passed. A cell phone blocker can transmit on the exact radio frequencies that these wireless devices are using.
This 'white noise' phenomenon disrupts the communication pathway between the base station located in the tower and the mobile handset. This disruption is technically known as "denial-of-service." The cell phone jammer kit is meticulously designed to cancel (deny) signals within the radio spectrum for handsets that are within the operational range of the jamming device.
How Mobile Jammers Get the Job Done
The primary purpose of cell phone blockers is to overpower mobile devices by sending out a standard signal on the same frequency as previously mentioned. Achieving this requires a significant amount of power to ensure that the two signals collide and completely cancel each other, ultimately leading to a disruption of services.
In basic terms, the cell phone is led to believe that there is no available service in the vicinity. Consequently, when users attempt to utilize their phones in a jamming area, it seems as if they are situated in a "dead zone" devoid of service.
How Can This GSM Blockage Be Accomplished?
While various cellular systems are equipped to handle a wide variety of signals, they all fundamentally rely on basic radio signals that are susceptible to interruptions. The GSM system, which is utilized in digital cellular networks and those based on PCS, operates within the 900 MHz and 1800 MHz bands in Asia and Europe, as well as the 1900 MHz band in North America.
The functionality of scrambler devices allows them to successfully transmit frequencies that can hinder CDMA, AMPS, GSM, TDMA, DCS, PCS, Nextel, and iDEN systems. As a result, both older analog mobile phones and modern digital devices are vulnerable to jamming.
What is the Average Effective Jamming Disruption Range?
This is largely dependent on the power of the unit, the surrounding environment, and the signal strength. Moreover, walls within a building can, to a small extent, reduce the effectiveness of the signal being transmitted by the signal disrupter.
Mobile blockers operating at lower power can effectively cease all calls within a range of around 60 feet, while more robust models can establish a "dead zone" that covers an area similar to that of a football field.
The Most Powerful Signal Jammer Devices on the Market
It is essential to understand that these powerful signal jamming devices are employed by law enforcement and relevant agencies, which have units capable of producing much larger dead zones. Certain government models can generate dead zones that extend well beyond a one-kilometer radius from the jamming device.
