Techopedia provides an explanation of cell phone jammer.
A cell phone jammer is comprised of:
- Antenna
- Voltage-controlled oscillator
- Tuning circuit
- Noise generator
- Power supply
- RF amplification
When a cell phone jammer is in operation, the majority of cell phones will display no network signal. Conversely, when the cell phone jammer is deactivated, the cell phones regain their functionality. It is important to note that cell phones utilize distinct frequencies for transmitting and receiving signals. Consequently, most cell phone jammers obstruct one or both of these frequencies, thereby effectively preventing communication on both ends.Cell phone jammers operate based on the principles similar to those of jammers utilized to block radio communication. They work by interfering with either the frequencies from the cell phone to the base station or from the base station to the cell phone.
Cellular signal blockers are employed by law enforcement and the military to restrict and interrupt communication in diverse scenarios. Specific entities utilize these blockers to impede corporate espionage by obstructing communication within sensitive zones. Additionally, certain individuals employ portable cellular signal blockers to deter others from using cell phones in close proximity.
Cell phone jamming is considered illegal in numerous countries, including the United States, except for military and law enforcement purposes. The United States has implemented stringent laws that prohibit the sale and purchase of cell phone jammers, making it one of the most regulated countries in terms of their usage. However, certain countries like Mexico permit the use of cell phone jammers in specific public areas like hospitals. It is important to note that laws pertaining to cell phone jammers vary across different countries.
The illegality of cell phone jammers can be attributed to three main reasons
Cell phone jammers have the capability to block individuals, including yourself, from placing 911 and other crucial emergency calls. Furthermore, they pose a significant threat to public safety communications and disrupt various other modes of daily communication.
This article provides an overview of the functionality of signal jammers, the reasons for their illegality in the United States, steps to take if authorized communication is disrupted, and how Cellbusters can assist with any inquiries regarding cell phone jammers.
Steps to Take in the Event of Jammed Authorized Communication
Are you concerned that a signal jammer might be responsible for the interference? Various factors, such as signal jammers, can lead to poor network connections:
- faulty equipment
- physical obstructions that block the signal
- lawful devices that are operating on the same frequencies
Prior to submitting an interference complaint through the FCC Consumer Complaint Center, it is advisable to troubleshoot any equipment and connectivity issues following the guidelines provided by the manufacturer and service provider. Apart from referring to the owner's manual and contacting the company's technical support, conducting an online search for your device/model and the particular issue could assist in pinpointing or eliminating potential causes.
