Mobile phone blocker is a mobile phone blocking program or mobile phone detection system, designed to prevent unauthorized mobile phones while allowing authorized mobile phones to run. Blocking cell phone signals can prevent certain critical foundations, unauthorized calls to courts, military installations, or certain environments that need to manage cell phone activity to control the control.

Please note that in some states, cell phone jammers are illegal. Although attention to information rejection has long been an integral part of the PLA’s doctrine, this jammer is mainly used in military locations or other places where the use of mobile phones is prohibited.

USS Boxer used electronic interference to take out Iranian drones, Pentagon sources say amphibious assault ship

The USS Boxer deployed electronic measures to dismantle a drone the US says was operated by the Iranian military, according to Pentagon sources familiar with the situation. The Navy says the drone was wrecked on the Strait of Hormuz on Thursday after it approached the ship and repeated warnings went unheeded.

Iran has denied the US claims, stating that all of its drones will be considered – and that the US ship may have accidentally shot down one of its own military drones.

U.S. Department of Defense officials, who were not empowered to speak publicly, said the drone was one of several threats to the boxer as he drove through the narrow waterway near the Iranian coast. It is said that at least one Iranian helicopter and several fast boats drove towards the ship on Thursday morning. The actions prompted the boxer to send a helicopter, which then flew side by side with the Iranian plane to repel him.

The boats eventually followed radio warnings to break contact, but the drone headed for the boxer instead of turning, the sources say. His presence was seen as a potential threat to flight operations aboard the amphibious assault ship, which carries a number of helicopters, as well as Osprey tiltrotor aircraft and a handful of fighter jets.

There were also concerns that the drone could pose a direct threat: in recent months, Iran-backed Houthi rebels have been using drones to drop explosives on targets in both Yemen and Saudi Arabia. According to a Pentagon source, the drone was unarmed in Thursday’s encounter.

The first US statements about the incident with the boxer did not contain any detailed information about the crash of the drone. On Friday, a Pentagon official clarified that the boxer was using electronic jammer measures to turn off the drone. The officer did not provide details in order not to disclose information about the ship’s capabilities.

The news site Military.com states that a new Marine Corps anti-drone system was responsible for the Iranian drone crash, although the military did not confirm the report. USNI News notes that the Navy previously announced that the Marines were operating the jamming system on the deck of a US ship. USNI News described the weapon as one of a new series of “non-kinetic systems” that can cause a drone to crash.

President Trump first announced the crash on Thursday afternoon, saying “The drone was destroyed immediately” after closing within about 1,000 meters of the boxer and ignoring the request to resign.

Shortly after Trump’s testimony, Pentagon spokesman Jonathan Hoffman gave further details, saying a drone approached the Navy ship at around 10 a.m. local time while the ship was in international waters and on an “inbound road transit” von Hormuz “sailed. “”

However, on Friday, Trump said the U.S. ship shot down the drone, contradicting Pentagon officials’ report that the boxer was using jamming features. “No doubt no,” Trump said in the Oval Office, according to a White House pool report. He added, “We shot it down.”

When asked if he was concerned about the possibility of a major clash with Iran in the Strait of Hormuz, the pool report quoted Trump as saying, “No, not at all. … We hope they don’t do anything stupid about them. ” When they do that, they pay a price no one has ever paid before. ”

Also on Friday, a senior Trump administration official said the U.S. government had evidence that the boxer destroyed the drone and said more information about the shutdown would come from the Pentagon.

“We have very clear evidence, the Department of Defense issued its statement on the boxer’s actions,” the official told reporters on Friday. “The Iranians don’t have a great story with the truth. We are very confident in the president’s announcement.”

When asked if the Trump administration would take further action against Iran, the official said the US was ready to defend itself.

“It was your drone that approached our ship,” said the officer, adding, “If you keep doing this. If you fly too close to our ships, you will be shot down.”

US military officials say Iranian helicopters and drones often flew near US ships as they crossed the Strait of Hormuz between the Persian Gulf and the Gulf of Oman.

In an incident that began in August 2017, according to these officials, a US ship was harassed by an Iranian drone that flew near the ship during night operations. No shots were fired, but the encounter was classified as “clearly unsafe”.

Terminator-signal jamming gun drone

What is a drone jammer?

The signal jammer is also called a signal blocker. They are devices that block radio communication signals. A pilot on the ground remotely controls an unmanned aerial vehicle (UAV). Therefore, blocking the radio signal makes a UAV useless. The drone will either fall to the ground or land, depending on its programming.

The jammers “had quite a significant impact” on the UN surveillance drones, which were suspended for days after gathering intelligence from the air. US military officials did not say whether the latest interference caused the drone crash, citing operational security.

But sources told NBC that Russia’s sophisticated jamming equipment, which was developed by its military, has proven effective even against some encrypted signals and anti-jamming receivers.

It is introducing DroneGun, a GPS signal blocker that disables drone signals (including GPS and GLONASS positioning) from up to 1.2 miles away. Like most rivals, it doesn’t destroy the target drone, it simply forces the vehicle to land or return to its starting point. Anti-drug teams can not only defuse threats from a safe distance, but they can also locate their pilots.

Most of today’s jammer-mart jammers use a broader jamming signal over a range of frequencies, while BEAM is configured to detect a single specific frequency used by an attacking drone, a solution especially suitable for urban or more populated combat zones.

portable drone signal jammers

US analysts first caught Russian military drones in eastern Ukraine four years ago, after the invasion of Crimea, according to Humphreys. He said the jammers were initially detected as faint signals from space, bouncing off the surface of the earth. The jammers “had quite a significant impact” on United Nations surveillance drones attempting to monitor the area, grounding the fleet for days and halting intelligence gathering from the air.

The drone signal jammer works by directing radio energy into the drone, interrupting the remote control link between the drone and the operator. The jammer operates in common industrial, scientific and medical (ISM) frequency bands. 2.4 GHz, one of the most common frequencies for drone control, is part of the ISM band.

The demand for anti-cell phone signal jammers is growing

In the past two decades, we have seen a dramatic increase in the number of users of mobile communication devices. This expands the cultural society’s demand for more effective and reliable signal encoders. Mobile jammer devices are becoming civilian products, not electronic warfare devices. With the increase in the number of mobile device users, the need to disable mobile phones in certain places has also increased, where the sound of mobile phones will be harmful. These places include places of worship, meeting rooms, hospitals, concert halls, meeting rooms, prisons and other places where silence is required. cell phone signal jammer is very effective in confidential meeting rooms, because important information may leak from one room to another without knowing anyone else. Jammers are very effective in breaking the communication between prisoners in prisons.

portable mobile phone radio jammer

Whether it’s theaters, educational institutions, cafeterias, restaurants, offices, or anywhere else, almost everyone uses a mobile phone. Today, people spend most of their time on mobile phones instead of spending quality time with their families or focusing on organizational goals. Although mobile phones can help you in many ways, they also distract many lives. This is the source of mobile phone network interference. Interference refers to the act of blocking something. Therefore, mobile device interference refers to preventing network signals from reaching your mobile phone, thereby denying access to the Internet and sending messages via SMS or phone calls.

Where do you need to use a mobile phone blocker?

If you have an emergency meeting and you don’t want anyone to answer unnecessary calls or messages during an important meeting, you can use cell phone blocking technology. This technology allows people to avoid calls and text messages without turning off their phones. Enabling this technology will directly block the signal from the base station and make the person unable to communicate with other people via mobile phones.

Although many people think that installing interfering devices in schools is not a solution, because children can access the Internet in various places, including open Wi-Fi areas at home and in cities, some people think this is a good idea. Adolescent children are not mature enough to use the Internet properly. Sometimes, out of curiosity or under pressure from peers, they may be exposed to content that shouldn’t be included. Installing jamming devices is a very good idea so that even if someone inadvertently does not make the mistake.

The role of drones in future warfare, what about drone jammers?

War is entering the era of drones faster than expected, and the “high altitude danger” of civilian drones is increasing, except for large drones like the Global Hawk. At home and abroad, the phenomenon of “black flying” and “flying flying” has emerged one after another, which has attracted more and more attention to security monitoring issues such as civil aircraft taking off and landing, eavesdropping in secret areas. In fact, the increasing number of unmanned aerial vehicle (UAV) crimes makes people pay more and more attention to the management of unmanned aerial vehicle (UAV).

drone signal jammer

The drone signal jammer market is developing rapidly, and UAVs are now playing a role in aerial photography, mapping, delivery, rescue and other fields. However, “problems” followed. These problems affected the order of aviation and the penetration of sensitive areas… These phenomena even led to the rapid development of the derivatives industry and unmanned aerial vehicles (uav). Equipment and service providers, unmanned aerial vehicle (UAV) “predators” have also benefited a lot from it, which brings huge development opportunities to unmanned aerial vehicle (UAV) companies.

The Chinese military has been equipped with the ability of the US military to use drones to interfere with radiation weapons. Large electronic warfare equipment can even destroy and capture enemy large drones. For example, Russia’s “automatic” countermeasure energy response system has some powerful functions that the outside world has not yet realized. The radar system can suppress 50 aircraft at an altitude of 30,000 meters, and can also conduct electronic attacks on fighter jets and unmanned aircraft within a radius of 100 square kilometers. In October 2011, Iran captured the US RQ-170 stealth drone “outpost” using an electronic countermeasure system provided by Russia.

Signal-oriented approach to signal congestion

Signal interference is an increasingly popular means for criminals to steal vehicles and cargoes, with truck hijackings costing the country an estimated R3 billion in 2015.

In almost every reported hijacking case, the truck’s tracking signal was not available because the suspects involved had used signal jammers.

The scourge of signal congestion in South Africa was brought to the public through carte blanche exposés and the much-noticed blocking of cellular communications during the “State of the Nation” address in Pretoria in 2015. The latter event, in particular, helped create greater public awareness and got companies like Ctrack to innovate and fight back.

However, signal jammer continue to be used in South Africa as they are easy to obtain and more affordable. As a result, hijackers today employ a wide range of jamming systems and devices, some of which are large and cumbersome and some of which are small and portable. This is despite the fact that possession and / or use of signal jamming devices is illegal under ICASA in South Africa.

High tech Phone Wifi interceptor

Big or small, these systems typically prevent telematics devices from transmitting their location to tracking service providers.

Hein Jordt, CEO of Ctrack Fleet Management Solutions: “Hijackers use a variety of jamming systems to block tracking devices from communicating over cellular networks or satellite. Once blocked, they usually hijack the vehicle or collaborate the driver together to take it to a place where they can unload their valuable cargo. ”

Transport and logistics companies know it is important to protect both trucks and their cargo from theft. According to the South African Insurance Crime Bureau, truck hijackings are primarily about the goods being transported, with FMCG products such as tobacco currently in high demand. Either way, the fact is that the majority of the trucks are hijacked for their loads.

Fleet owners and operators need a total transportation solution that combines fleet management with the ability to detect signal congestion. The good news is that today there is a solution that can provide both trucks and trailers with effective stowage protection.

To attenuate signal jammers, alternate frequencies to those that are being blocked must be used. This is where the DSSS (Direct Sequence Spread Spectrum) technology used by Ctrack comes into play. DSSS does not use any other format like GSM to communicate. Instead, it transmits messages with a bandwidth that exceeds the bandwidth required by the message signal.

This spreading of the transmitted signal over a wider bandwidth makes the resulting broadband signal appear as a noise signal that allows greater resistance to intentional and unintentional interference. DSSS is also designed to carry signals from difficult radio frequency ranges and can penetrate through concrete, making it ideal for urban, retail and financial institutions environments.

In March, Ctrack announced that the interfering signal detection solution would be part of a combined fleet management package. “We are now able to offer our customers the option of installing a gsm jammer fault detection module as part of their fleet management system to ensure continuous visibility and to combat vehicle theft,” said Jordt.

With the fleet management component, fleet owners can monitor driver behavior such as B. Monitor hard driving, accelerating, braking, cornering and driving too fast. Significant fuel and maintenance costs are also saved by monitoring factors such as engine performance and fuel consumption.

Install a weighbridge jammer, one-third less cargo

Recently, the Nanyang Police Station of the Shijiazhuang Chang’an Sub-bureau destroyed a criminal gang that used weighbridge jammer to steal property. Xu is the person in charge of a heating pipe fittings factory. Since the beginning of this year, when his factory sold waste heating pipe fittings, the number of the factory did not match the actual quantity. It was suspected that someone had done tricks on the floor scale.

super power signal jammers

On October 19, 2020, Xu also negotiated a deal with Liu, who purchased waste heating pipe fittings. Liu Moumou took someone to install the accessories of a certain Xu truck and drag it to the weighing house in the west of a certain village in Chang’an District. After weighing the pounds, Xu felt that there was no shortage of cargo in this truck, so he reported the case. The police from the Nanyang Police Station rushed to the scene immediately and took control of Liu Xumou and others and the weighing house owner Dong Xumou. The weighing jammer was seized on the weighbridge at the scene.

After interrogation, Liu XX and Dong XX confessed that before the weighing, one of Liu’s parties who purchased the accessories had sent someone to install the jammer on the floor scale, and controlled the floor scale when weighing to reduce the weight of the goods. After calculation, the weight of Xu’s vehicle accessories was reduced by one-third, and the direct economic loss reached more than 23,000 yuan.

At present, the criminal suspects Liu Moumou and Dong Moumou have been detained under criminal law, and the case is under further trial.

Jammer invalidates ultra-precision weapons

Arexis jammer has the ability to filter and thus protect the approach and departure of entire strike formations from low frequency radars through the intelligent use of DRFM jamming techniques, such as smart noise, false targets coherent and various saturation techniques.

But the service still kept MAPS in the background. Its goal was to develop an open architecture – the MAF (Modular APS Framework) – which could be used on any current or future armored vehicle to plug in and use the best radars, cheap gps jammers, and death shooters from different vendors. This way, the military can easily update vehicle protection with new technologies available from all vendors.

The GPS jammer is a little more difficult when the trajectory is made several kilometers away. American Missiles Ballistic missiles usually have their destination in mind long before they are close to the target. They also have a nifty method of calculating distance to target that is not dependent on GPS as they get closer. Even so, GPS disturbances are very difficult on a large scale. But it’s not too difficult to make minor changes, just enough to render super-precise weapons ineffective. When you know someone is going to be operating in a very specific area, like the ships we broadcast around the world. Or, say, one of our stealth drones that we kept flying in the same reconnaissance mission over and over again (looking at Iran). It’s easier to fuck. Because you know pretty much exactly where they operate, so you can focus on that specific area. It’s easy to fuck with practice ops.

anti-tracking gps blocker

Thus, weak radar cross sections and radar absorbing materials will be a necessary, but not sufficient, characteristic of sixth generation fighters. Some theorists argue that advanced sensing technology can eventually render stealth cells obsolete – and they can’t be upgraded as easily as avionics and weapons. Therefore, jamming, electronic warfare, and anti-infrared defenses will also gain importance.

The fusion of sensors and optional management, however, means that the sixth generation jets rely heavily on data links and networks that could be disrupted by jamming or even invaded by hackers. Ground logistics networks, such as the F-35’s ALIS system, promise to dramatically improve efficiency, but even expose aircraft on the ground to a possible cyber attack.

The B-52 weapons developers added that a second element, slated for completion by 2022, would incorporate more modern or advanced weapons, such as the remote air-to-surface missile, or the JASSM, the JASSM Extended Range (ER) and a technology called Miniature Cast Lure, or MALD. A variant of the MALD-J “jammer”, which will also be integrated into the B-52, can also be used to block enemy radar technologies.

Jammers: High-density objects can block 4G networks and sound alarms

Once they become true secret agents or tools only available to the armed forces, but for those who are not familiar with mobile phone jammer, they know that they are special electronic devices that allow you to jam the frequency of your smartphone.

When sold on the Internet or in specialized stores, the jammer will prohibit the use of GSM, wifi, 3g, 4G and GPS frequencies that we usually use with various TIMs, Wind Tre and Vodafone. Their operation is to send out radio waves that dominate and disturb signals used for phone calls or satellite tracking.

cheap car gps anti tracker jammer

The difference between a cheap jammer and a high quality jammer is the coverage, the power of the noise signal and the number of existing antennas. Once activated, the tool starts to fill the required interference signal frequency with a 180-degree range.

The power of the jammer is expressed in watts or decibels, and the number and type of antennas will affect the coverage and interference range. However, it is precisely because jammers are spreading on the Internet at a price that everyone can obtain, people have tried to prevent this phenomenon by effectively detecting countermeasures for frequency jamming equipment. They are called “anti-jamming devices” and they send alarm inputs when they detect disturbing electromagnetic radiation in the surrounding environment.

Jammer VS Bugs Who Will Win?

We have recently been able to read in all the newspapers about the scandal now called “Mafia Roma Capitale“. Mostly, some intrepid journalist wanted to venture, probably because he had been lucky enough to read some minutes, or who knows what “tip”, on the use by the alleged criminal organization, of appearing “jammers” and cards in the name of third parties , in order to divert the investigation.

Both the first, the so-called wireless jammer, are addressed as NOT working, for the diversion of investigations carried out by the authorities in charge. We obviously have no “paper” in hand, just as we have no “tip”, so we limit ourselves, as far as it can be reliable, to answer the question of greatest interest; how was it possible to intercept the subjects even when they had the jammer on?

gps wifi cell phone jammers

The answer is simpler and more obvious than you might think, already visiting and reading our previous news, specifically “Which Jammer to choose”, you can give an answer to everything, but we would like to clarify again, below we explain in detail:

To be able to secure an environment, it is NECESSARY TO HAVE MORE THAN ONE JAMMER and more.

The frequencies used by the signal are wide, there is NO portable signal jammer in the world capable of canceling them all. Conceptually, it is a bit like having a room with a hypothetical number of 10 doors, closing 1 or 2 does not preclude the opening of the remaining ones.

The pocket jammers, let’s talk about the best, inhibit the frequencies of cell phones and at most the 2.4GHz WiFi network or GPS. They leave the “doors” open for all VHF – UHF radio bugs, or perhaps high radio frequency bugs and why not, directional laser pointing or more simply bugs with direct recording to MicroSD, which, the latter two, cannot be inhibited with no jammer!

Moral of the story, the device purchased could NOT be sufficient to make a safe environment.
In order to make a safe environment, at least it must cover ALL VHF UHF frequencies, cell phones, high radios and other equipment such as white noise generators aimed at protecting conversations from any recorders and / or directional. This is the only technical explanation, the rest is just chatter from bars or the writings of “newsagents” paid for by third parties.

As in any survey, most of the wiretaps carried out are by telephone. The cards, even in the name of third parties, are NOT safe. There are various methods to be able to intercept them and charge the end user. The only secure systems are encrypted mobile phones, where conversations can NOT be listened to and neither appear on any printout.

This is not intended to be a “guide to the criminal”, but it seems more than appropriate to clarify and tell the truth about the facts.
