There is a way to safely eliminate these problems immediately, by using a cell phone jammer. Learning how signal jamming works on wireless devices will make it possible to clearly understand and appreciate their overall value.

Being able to successfully disrupt a cell phone signal is basically the same as being able to jam any other type of mobile radio communication with a standard signal blocker. Keep in mind that a wireless device is able to function by communicating directly with its designated service network through a base station or tower. These towers divide cities into cells or smaller areas.

Although different cellular systems process a wide range of different signals, all networks use basic radio signals in a way where they can easily become interrupted. GSM2, the system that is used within digital cellular as well as systems that are based on a foundation of PCS, operate within the 900-MHz as well as 1800 MHz bands located either in Asia or Europe as well as the 1900 MHz band in North America.

However, keep in mind that such powerful signal jammer units are used by law enforcement officials, and agencies, with units capable of a much larger dead zone. Some government models are capable of creating dead zones that extend for much farther than a one Km radius from the jamming device.

The use of a phone jammer, GPS blocker, or other signal jamming device designed to intentionally block, jam, or interfere with authorized radio communications is a violation of federal law. There are no exemptions for use within a business, classroom, residence, or vehicle. Local law enforcement agencies do not have independent authority to use jamming equipment; in certain limited exceptions use by Federal law enforcement agencies is authorized in accordance with applicable statutes.

The use or marketing of a jammer in the United States may subject you to substantial monetary penalties, seizure of the unlawful equipment, and criminal sanctions including imprisonment. 

So, I know that there are many articles on the Internet about Wifi Jammer, which can disconnect all stations from Wifi and create a lot of headaches, but I've never seen people talking about Optical Fiber jammers.

As we know the nRF24 work at 2400 MHz, 3G and 4G LTE network uses 1700 MHz and 2100 MHz frequencie and (Wiki) : Wi-Fi (or WiFi) is a local area wireless technology that allows an electronic device to participate in computer networking using 2.4 GHz UHF and 5 GHz SHF ISM radio bands.

Is there a possible way of coding to "Jam" the mobile or Wifi, FM,...etc in a room or depending on the

range or the nRF.

As i know jammer is a device that transmite High noise signal so the other normal freq are "blocked", "waved away" like a wave (you can say it like that)

Signal jammer is a device that blocks transmission or reception of signals, usually by creating some form of interference at the same frequency ranges that cell phones use. It is created to help people solve different problems coming from cell phones, radio signals and wireless connections. Every kind of it is designed to work with a specific frequency range. Of course, the design of jammer is more and more inclined to comprehensive performance. That means a jammer can block more and more frequencies

This equipment is manufactured to block signals in environments where cell phone activity may not be desirable, such as theaters, churches, classroom, library and operating rooms. Portable personal jammers are available to enable their owners to stop others in their immediate vicinity from using cell phones. It is easy to use and carry. The desktop jammer has better jamming performance and larger electronic jamming range

Telephone calls may be eavesdropped, WiFi may be compromised, electronic devices with cameras may be invaded, personal privacy has received a great threat. Not to mention the ubiquitous drone and GPS positioning. In order to protect your personal privacy and communication security, may be you need try using wifi jammer.

Just as a parent has the ability and right to cut off the Wi-Fi at home, they should have the option to cut the cellular signal if desired. Grabbing phones from hands to put them in airplane mode probably won't work, and making the house into a Faraday cage is an extreme only the tin-foil hat crowd should try. But an in-home cell phone jammer should be an option whenever desired or necessary.

However, in the United States, if you own a car, this device is also required. Why say so? For two reasons. The first reason is GPS tracking. As GPS trackers become more available in the United States, you never know when you're being tracked. The second reason is driving safety. As we all know, young people nowadays can't live without their mobile phones. It's not hard to imagine them using it while driving. This is very dangerous!!! So we need a jammer to prevent them from using mobile phones

In addition to the above devices, the anti-tracking jammer is also very necessary. Now, because GPS tracking devices are so easy to buy, they're easy to install on a car. At this time, GPS backtracking jammers are required.

Determine how often you want the jamming signal before buy jammer.If it's legal in your area, all you need to do is buy one and turn it on close to your network source to blocker signal.The shielding range of the wireless network jammer is related to the strong electromagnetic field of the shielded site and the distance from the communication station.

Radio jamming refers to interfering with the transmission of radio signals in such a way that a receiver cannot properly decode the signal. It is usually achieved by using RF jammer or RF blocker RF blocker.

I can't give specific advice on whether you need a portable or tabletop signal jammer, as the decision depends on your specific needs and situation. However, here are some factors to consider when choosing between portable and tabletop jammers:

How many mobile phone signals need to be blocked, whether the signal jammer is versatile enough, and can block multiple signals at a time, I can't give specific suggestions. However, here are some general considerations:  Number of Signals: A signal jammer can be designed to block one or more signals at the same time. The number of signals that can be blocked depends on the design and capabilities of the jammer. It's important to choose a jammer that blocks the specific signal you want.  Individually Blocked: Some signal jammers can be designed to block individual signals, such as the GSM or CDMA signals used by cell phones. This is useful if you only need to block certain signals while allowing others to pass.  Interference: It is important to note that signal jammers may interfere with other communication systems including Wi-Fi, GPS and emergency services. Some jammers are designed to minimize interference, but it is important to consider the potential impact on other systems before using a signal jammer.  Overall, it's important to carefully consider your needs and potential risks before using a signal jammer. If you choose to use a signal jammer, please ensure that it is used responsibly and in compliance with all applicable laws and regulations.   High Power Benchtop signal disruptors for sale

To block mobile phone signals within a specific range, a so-called mobile phone signal blocker, also known as cell phone jammer, can be used. The working principle of a mobile phone signal blocker is similar to an RF jammer, which interferes with the communication signal of the mobile phone by transmitting radio signals, thereby preventing the mobile phone from working properly within this range.

The use of radio jammers can achieve the shielding of radio signals within a certain range. A radio jammer is a device that emits a radio frequency signal at the same frequency as the target radio signal, which interferes with communication between the radio transmitter and receiver.

However, it should be noted that the use of radio jammers in most countries/regions may lead to serious legal consequences. The use of radio jammers can damage critical communication systems such as aviation and navigation systems, and may lead to property damage. Therefore, radio jammers can only be used under authorized and necessary special circumstances.

Avoid using radio jammers and instead take legal and safe measures to protect radio communication. One such measure is to use encryption technology to protect communication between the transmitter and receiver. Another measure is to use directional antenna to concentrate the transmission of radio signals in a specific direction, which can reduce the interference to other radio signals around.


The solution to this problem is cell phone jammers. For a long time, they have been actively used by special forces, large theaters, music halls, and several companies.
