Signal Jammer Tech

A man sought in relation to multiple home invasions in Queens, New York, was caught on a home security camera while trying to use a Wi-Fi jammer to obstruct the signal of a Wi-Fi-enabled security camera. The signal, however, was reestablished, allowing the camera to document his actions.

The suspect reportedly entered homes during the day, taking valuable items such as cash, jewelry, and luxury possessions, while ransacking the interiors. It was ambiguous whether the police were investigating a single suspect or multiple individuals who might be working in collaboration.

As reported by ABC 7 NY, it appears that the homeowners are often not present at the time the suspect arrives, which tends to happen just as they are leaving. Since July 24, New York police have confirmed that at least five homes have experienced break-ins under comparable circumstances.

In a recent incident, the residence of Imran Ahmed in Queens Village was breached during a break-in.

The security camera footage, which is Wi-Fi-enabled, was unable to be disrupted during parts of a home invasion. The video depicted a troubling sight of a man, concealed by various pieces of fabric, slithering across the floor. He was seen maneuvering a backpack and a black box, thought to be a Wi-Fi signal jammers. Nevertheless, his attempt to disable the camera was unsuccessful, as it continued to transmit signals and recorded his actions while he was in the residence.

Ahmed indicated that they were alerted at about 2:30 regarding the disruption of their Wi-Fi service. He noted that initially, he "didn't pay it much attention."

Within the video, a man is seen moving up the stairs, and when he descends, he expresses a sound akin to, "Tony, Tony, Tony, Tony."

Ahmed indicated that they were located only two blocks from the police precinct. He noted that having an event of this nature transpire is very unsettling.

The police are currently investigating a residence where $30,000 in jewelry was taken, along with a Louis Vuitton handbag worth $8,000.

What do you need to know about the growing crime of electronic devices – ‘key jammers’ – that prevent cars from locking?

Such devices can be easily obtained through online platforms and are designed to obstruct the signal from the key fob. This leads to the misconception among careless drivers that their vehicle is safe, when it is, in reality, unprotected.

This opens the door for individuals with malicious intent to pilfer your items or possibly your car.

The effective range of a low-powered signal jammers can reach about 75 meters, suggesting that a substantial area, including an entire parking facility, can be disrupted concurrently.

Yet, those who commit crimes while armed with wifi blocker are able to target any location, rather than being confined to public parking facilities.

When I awoke to get ready for my job, I walked outside and observed that all the car doors were firmly closed.

I experienced a profound shock when I understood that I had locked the car, given that I was staying at my boyfriend's place and had left my Christmas gifts inside. When we subsequently looked inside, we were appalled to discover that the car had been thoroughly upended and all valuables had been removed.

The police initially communicated that there was little they could do regarding the incident. They did not send anyone to look for fingerprints, as there were no clear signs of a break-in. However, when I contacted my bank to cancel my card, I found out that the thief had been using my contactless card. This prompted the police to take the matter more seriously and become more involved.

They are in the process of analyzing the CCTV footage with the intention of capturing the perpetrators.

How can you make sure your car is secure?

The only reliable means of determining if a car is locked is through a manual inspection. Most vehicles display other signs of lock engagement, including flashing lights, mirrors that retract, or a short honk from the horn.

If you are situated sufficiently close to the car, you can also hear the distinct sound of the central locking activating.

Deputy Chief Superintendent Jukes remarked that it is crucial for people to be attentive to electronic intrusions of this kind.

Individuals are advised to monitor their vehicles and belongings closely to prevent providing any motivation for criminal acts. This involves manually confirming that the vehicle is locked and ensuring that all valuables are removed prior to leaving.

To bolster the security of your vehicle, one might consider purchasing a car jam detector, a technological device that emits an alarm when it detects a jam.

Will insurance companies cover such thefts?

Ms. Dover brought attention to a critical concern for victims: in addition to losing their belongings, they often cannot substantiate that they forgot to lock their vehicle. Most insurers will deny claims for theft if the car is left unattended and not locked.

The Financial Ombudsman reports that many insurance companies do not provide theft protection for vehicles that are left unlocked and unattended.

The definitive means of proving that a car lock is jammed involves catching the thief, although a recurring pattern of thefts can constitute significant evidence.

Thames Valley Police is examining 14 recent cases of lorry, van, and car thefts, noting that there were “no obvious signs of break-in” in these instances.

Throughout the last two weeks of November, thefts were recorded at various service stations along the M4 motorway in Berkshire.

Sandra: My mother has recently overlooked placing her current insurance card in the car, leading to her anxiety about driving without it. I was under the impression that she did not have it, but I was uncertain whether she would be breaking the law if she could not provide it. Is it unlawful to drive with an expired insurance card?

At present, law enforcement requires individuals to display a valid insurance card, which can be presented via a mobile device or as a digital image. In cases where a parent’s insurance card has expired, many police departments are connected to the state insurance network, allowing for immediate verification of a vehicle's insurance status. If the police can confirm the insurance is valid through this system, there should be no grounds for issuing a citation.

Ty: Considering that it is lawful to possess a radar detector in Texas, are there any devices that are illegal to use in combination with a vehicle's radar detector?

In the state of Texas, the use of radar jammers and laser jammer is strictly prohibited. The Texas Traffic Code specifies that no person may use, attempt to use, install, or operate a radar jammer in a motor vehicle, except in the course of a law enforcement officer's official duties. Therefore, if you possess a radar jammer in Texas, it is advisable to keep it stored on a shelf at home alongside your preferred reading material. Moreover, the law forbids the purchase of radar jamming devices, stating that no individual shall buy, sell, or offer such devices for sale. These signal jammers are typically utilized by those who engage in extreme speeding. It is essential for drivers to recognize that these devices may not work as intended. Following the law would undoubtedly simplify many aspects of life.

I pray daily for the safety of all police officers. I am aware that your job is perilous, as you work to protect the safety and welfare of all citizens, not just those in your immediate vicinity but throughout the state of Texas. I experience parking issues on my street regularly. While attempting to exit my driveway, I noticed a vehicle parked directly behind it, across the street. I have previously communicated with my neighbor regarding parking matters. I do not wish to inconvenience anyone by parking improperly. What should I do in this situation? What violation does this entail?

Parking difficulties have been a long-standing issue, and it is imperative to address your concerns, as well as those of others in similar situations. It is essential to understand that your neighbor did not commit any wrongdoing by parking their vehicle on the opposite side of the street, behind your driveway. I acknowledge the stress and challenges associated with safely exiting a driveway; however, the law does not require drivers to alter their parking practices. It would be wise for you to continue engaging with your neighbors, expressing your desire for them not to park in that location to mitigate the risk of damaging their vehicles. Additionally, be mindful that if you were to hit a parked vehicle while reversing, you could be liable for unsafe backing. Therefore, if you find it unsafe to back up, it is advisable to refrain from doing so.

Is it possible that networking phones collectively to operate as a comprehensive distributed antenna could provide a solution against Russian electronic warfare?

A company based in the United States, which is working on a system in Ukraine, indicates that networked cell phones with tailored software could represent an inexpensive and readily deployable response to the complex electronic warfare methods utilized by Russian forces.

Russian electronic warfare capabilities, which encompass signal jamming and GPS spoofing, pose significant challenges for Ukrainian troops in their operational effectiveness, particularly regarding the use of drones and advanced U.S. weaponry. The ability to detect and pinpoint enemy jamming devices often relies on sophisticated software-defined radios, which are typically provided to the United States and other well-funded military forces. Conversely, smaller militaries, such as Ukraine's, struggle to obtain these vital resources in large quantities due to budgetary restrictions.

The potential creation of an inexpensive system to detect enemy jamming apparatus could assist Ukrainian operators in regaining an edge over their better-equipped adversaries. This innovation could also transform the approaches taken by cellphone network providers to ensure their devices are resilient against sophisticated forms of attack.

Around the Christmas period of the previous year, the Ukrainian military made contact with Sean Gorman and his associates at Zephr, a company that specializes in reinforcing devices against GPS-signal interference. Zephr swiftly delivered six Android Pixel phones, equipped with their software, to Ukraine, and in April, they began conducting field tests near the frontlines in Donetsk.

In an interview with Defense One, Gorman explained that the phones were attached to drones, integrated into vehicles, and established on stationary platforms. They have also carried out controlled experiments utilizing their own signal jammerss to ascertain the precise location.

The foremost objective was to assess whether typical consumer smartphones, operating in unison within a network, could expose the existence of an entity attempting to interfere with GPS location data. The study revealed that by evaluating the GPS reception from various phones, they could identify when one or more devices were subjected to an attack.

Gorman remarked, "We are effectively taking advantage of the sensors found in mobile phones. The most significant sensor is the raw measurements from the global navigation satellite system (GNSS) that the device supplies. This includes automatic gain control (AGC), Doppler sensor data, carrier phase, code phase, and other metrics that smartphones gather regarding their distance from satellites, cell towers, and various network apparatus."

Manufacturers embed these sensors in cell phones to facilitate performance optimization, such as locating the nearest cell tower. The data collected from these sensors is integral to the GPS-processing software that enables phones to provide users with their precise location. By obtaining this information from a wide array of devices, it is possible to determine which phones may be compromised.

Gorman remarked that the computational AI operating in our backend, paired with the advanced techniques for processing signals and software, opens up numerous possibilities. Rather than depending exclusively on sensors or high-cost antenna arrays, one can achieve a great deal by networking mobile phones to act as a unified distributed antenna.

The evaluations also brought to light new findings concerning Russian electronic warfare.

Russia is engaging in the spoofing of GPS signals in the Baltic Sea, which results in receivers displaying false location information. NATO officials have indicated that this creates an unsafe scenario for passenger aircraft. A common strategy to mitigate drone threats involves GPS spoofing, which misleads the drone into thinking it is over an airport, necessitating a landing or retreat from no-fly zones.

On the frontlines in Donetsk, reports from Ukrainian soldiers frequently mention spoofing attacks on their drones. However, Gorman and his team have determined that a large portion of these incidents classified as "spoofing" are, in reality, high-powered jamming attempts. Since these jamming efforts operate within the same frequency bands as GPS or GNSS, they can mimic satellite signals, thereby creating the illusion of phantom or ghost satellites in locations where they cannot feasibly exist and still provide a signal, such as below the horizon.

Gorman articulated in a write-up for Defense One that the noise observed does not align with the usual characteristics of a GNSS signal; nevertheless, it does exhibit energy at the frequencies where the receiver is searching for satellite signals. The receiver employs signal-processing algorithms that utilize correlation techniques to identify and monitor satellite signals. The presence of a strong jamming signal can result in false correlations, misleading the receiver into believing it is detecting satellites that are not truly present.

The organization, now contracted by the Ukrainian government, is working to progress their research to not only detect cell phone jammer but also to accurately triangulate their positions, which would allow for their avoidance or removal.

Gorman indicated in an email that the advanced techniques being created will assess the location of signals of interest through three distinct inputs: 1. range-based localization inferred from power; 2. localization by area of effect; and 3. triangulation of jammers based on the angle of arrival. Each smartphone will detect the interference signal, log the last known position, and timestamp the reception, thus providing data points throughout the network. By centralizing and processing these signals, the system will effectively triangulate the position of the jammer.

The military of the United States is heavily investing in alternatives to GPS, which are generally referred to as alternative position, navigation, and timing, or Alt PNT, to assist people, drones, and other systems in ascertaining their geographical positions. However, these investments have frequently failed to produce significant returns.

Gorman remarked that the functionality of the system relies on an initial known position, and acquiring this position is almost unattainable without GPS assistance.

This networked approach is not intended to replace existing, more expensive military systems that are used for detecting and locating jammers. Instead, it offers a quick and cost-efficient solution for military forces like Ukraine and other groups vulnerable to jamming activities, including first responders. Furthermore, while it will not supplant the development of alternative positioning, navigation, and timing techniques, it could enhance their effectiveness.

Gorman proposed that there may be a significantly different way to approach this issue. Rather than concentrating all resources on Alt PNT and GNSS resilience, which are highly beneficial, it might be worthwhile to explore how this situation has evolved into a reality. He highlighted the need to effectively map and analyze the area in relation to the emitters, so that we can avoid those zones and eliminate the emitters.

As of June, Sheriff Noah Robinson of Vanderburgh County had not previously considered the serious implications that signal jammers could have on law enforcement activities.

This marked the occasion when his office detected one residing in the back of a vehicle.

Robinson conveyed to an interim legislative committee last week that the office had received a call regarding a burglary in progress. The staff utilized the subdivision's camera systems to track down a vehicle that was transporting the suspected burglars.

It was noted by Robinson that the officer's radio and computer stopped working at the moment the car was pulled over.

Capable of blocking Wi-Fi, Bluetooth, GPS, and other communication signals, signal jammers can disrupt the operation of devices like smartphones, Ring doorbells, and wireless alarm systems. Robinson reported that the wifi jammer identified by his office has a range of one mile.

He addressed an interim panel that is centered on the criminal code, imploring the lawmaker-dominated group to reflect on the potential enactment of a new law that would criminalize both the importation and the various uses of the devices.

Robinson pointed out that there is no need to elaborate further to see that this has other significant applications, especially from a terrorism perspective.

He detailed scenarios in which bad actors could potentially compromise medical devices in hospitals, disrupt police communications through surveillance towers, access the mobile phones of ordinary citizens via cellular towers, and even control traffic flow through wirelessly operated traffic signals.

The federal government classifies signal jammers as illegal. The Federal Communications Commission strictly prohibits the marketing, sale, or use of any device that interferes with authorized radio communications.

As stated by Representative Matt Pierce, a Democrat from Bloomington, prisons are unable to implement signal jammers as a means to tackle the issue of unauthorized mobile devices.

Senator Lonnie Randolph, representing the interests of East Chicago, sought clarification on why it would be pertinent for Indiana legislators to consider changes when there is an existing federal ban on the devices in question.

Robinson remarked that Indiana officers do not have the statutory backing to enforce the law "immediately," as no state statute exists to support this authority.

Leading the interim panel and the House’s Courts and Criminal Code committee, Representative Wendy McNamara stated her belief that Robinson’s office had a fortunate outcome, suggesting that it "could have been much worse."

She indicated, however, that the laws pertaining to the technology may not be implemented in a timely manner.

McNamara stated to reporters that, quite frankly, we do not have a formalized concept for handling the issue of signal jammers at this time.

Officials in La Cañada Flintridge began noticing thieves were using Wi-Fi blocking devices to bypass home security systems like cameras and door sensors.

In response to an increase in home break-ins by “sophisticated criminals” in the San Gabriel Valley, the city of La Cañada Flintridge announced Tuesday that it has increased law enforcement patrols and begun taking steps to curb crimes that rely on new technology.

Arabo Parseghian of the city’s administrative services department said the city is working with the Crescenta Valley Police Department and Los Angeles County to expand police presence while officials try to stop thieves who are taking advantage of wireless technology.

“For wireless cameras, alarm systems and door sensors, a lot of criminals are now trying to rely on Wi-Fi jammers to combat them,” Parseghian said.

He said city officials began noticing criminals were using Wi-Fi jammers to get around them. Blocking devices to bypass security systems so that even if a burglary occurs, they won’t alert homeowners.

An attempted burglary a few months ago confirmed officers’ suspicions when deputies found items left behind by the criminals, Parsekin said.

“They left some equipment behind, one of which was a Wi-Fi signal blocker which we seized as part of the evidence in the burglary, and we’re seeing this as a trend among criminals today.”

He added that the city has seen seven to eight burglaries a month lately.

In addition to the increased patrols, the sheriff’s department will do some undercover work, and the city will also purchase Flock Safety cameras, which can read license plates and flag suspicious vehicles, including those that may have warrants.

City officials also recommend that homeowners update the firmware on all firewalls and home security devices and install glass detectors on doors that can send alerts.

With the summer holidays approaching, authorities are encouraging residents to sign up for “vacation checks” with the sheriff’s department and to communicate plans with trusted people.

“If you trust your neighbors, if you have a good relationship, let them know, ‘Hey, I’m going out of town.’ ”

If a new British-developed jammer is successfully implemented, it is anticipated that aircraft and missiles operating in enemy territory will increasingly rely on drone jammers flying ahead to disrupt and block air defense systems.

Unlike established standoff jammers that are positioned on large aircraft to avoid threats while effectively neutralizing enemy radar from a distance, Leonardo is set to release a new "standoff" jammer that is compact enough for drone deployment and economically feasible for rapid implementation.

The Internet is an extremely powerful tool that provides endless possibilities for work and play, with access to a wide range of information in just a few clicks. However, it also poses significant risks to privacy, security, and authority, both in professional and private settings.

It is a common reality that WiFi networks are easily misused. To combat these issues, using a WiFi blocker may be a solution. Whether you want to regain control of your family life, workplace, or protect your children, a Wi-Fi blocker can give you peace of mind.

Key Reasons You Absolutely Need a WiFi Blocker

1. A Wi-Fi blocker is an effective way to prevent students from cheating on classroom exams. By blocking Internet access, students cannot search for answers on their phones or access online resources. For laptop-based exams, you can ensure the integrity of the exam by having students download required documents before enabling the Wi-Fi blocker.


2. A Wi-Fi blocker can also serve as a form of parental control, allowing you to regulate Internet access for unruly children. If your children are using the Internet late at night or accessing inappropriate content, you can control their Internet usage when necessary. While some tech-savvy kids try to reactivate routers when left unsupervised, you can use a Wi-Fi blocker to maintain control over internet access.


3. Wi-Fi blockers are often used to prevent unknown and unwanted devices from transmitting data to malicious actors. Surveillance devices such as hidden cameras and microphones may be found in certain locations such as hotels, locker rooms, and Airbnb rentals. While some may have legitimate security purposes, others violate your privacy by recording your activities.


4. By using a Wi-Fi blocker, you can prevent surveillance devices from transmitting these recordings over the internet, thus protecting your privacy. Additionally, Wi-Fi blockers help prevent alarming activities such as webcam hacking, where someone gains unauthorized access to your laptop's camera and can remotely monitor your behavior.

Buying a WiFi Jammer

Before buying a WiFi jammer, it is important to evaluate the performance of your WiFi router. Different router models offer different levels of control and settings.

The general rule is to choose a WiFi jammer that can pinpoint the frequency on which your WiFi router communicates with your devices. To achieve this, you should identify the specific channels that your router supports and buy a signal jammer that can block at least one of those channels.

For example, if your WiFi router can be manually set to work only on the 2.4 GHz band, a simple jammer that blocks the 2.4 GHz frequency will be enough. However, if you don't have control over the channels of your WiFi router, you'll need to invest in an advanced WiFi blocker.

If you plan to use your WiFi blocker in different locations outside of your home, the process becomes more unpredictable. It may not always be possible to determine the performance of wireless routers in different locations. In this case, you can either equip yourself with a router that covers the most common channel options or invest in an advanced Wi-Fi blocker that can cover a wider frequency range.

Different types of WiFi jammers:

• Portable jammers: These compact devices are easy to carry and can fit in your pocket. They are suitable for personal use and offer limited protection.


• Larger models: Some WiFi jammers require a wired connection and offer stronger blocking capabilities. They are usually used in fixed locations and can cover larger areas.


• Frequency and range: WiFi operates on two main frequencies: 2.4 GHz and 5 GHz. Most jammers focus on blocking the popular 2.4GHz frequency. But for full protection, it is recommended to choose a model that covers both frequencies. Wi-Fi jammers vary in range, from short-range jammers with a range of 15 to 20 meters to more powerful models with a range of up to 250 meters.

WiFi and Bluetooth Jammer Selection

Our Bluetooth and WiFi Jammers are for Sale in Several Models

Picking the right WiFi or Bluetooth blocker is not as difficult as it might seem.

It is important to understand that WiFi is available in 2 frequencies, 2.4GHz and 5GHz. While 2.4GHz is by far the most commonly used, some newer routers do include 5GHz.

Bluetooth is within the 2.4GHz band, so any WiFi jammer that covers 2.4GHz is also going to block Bluetooth.

The next important consideration is the size of the coverage area needed for your application. We offer units such as the 5GHz which covers both 2.4GHz and 5GHz to approximately 15 meters, the popular spy camera jammer which covers 2.4GHz WiFi only to approximately 20 meters, or the extremely powerful WiFi-5G which covers both, up to 250 meters.

There are some variations in the coverage area depending upon local signal strength, physical environment, etc. Where the signal is weaker, the coverage is greater, and vice versa.

What can cell phone jammers be used for?

Known as cell phone blockers or jammers, cell phone jammers are devices that obstruct radio signals, affecting cellular networks, Wi-Fi, and GPS systems through the emission of radio waves. These devices generally operate within a range of 10 to 40 meters.

Both the military and government have developed systems that can effectively interfere with radio communications across extensive areas.

By utilizing jammers, retailers can obstruct customers from conducting price comparisons within the store, which can lead to an increase in their sales.

In specific settings that demand quiet or reduced distractions, signal jammers prove to be beneficial. They can eliminate interruptions caused by ringing cell phones in theaters or chatter among youth in schools.

It is possible for criminals to utilize jammers to hinder the functionality of wireless alarm systems and other radio connections, which can prevent emergency calls from being placed via the mobile phone network.

WiFi Interference

• How it works: WiFi uses the 2.4GHz or 5GHz frequency band. Jammers emit powerful signals in the same frequency band, causing data communications between the router and the device to be blocked.


• Impact: Internet access becomes slow or disconnects completely, and devices cannot connect to the wireless network.

GPS Jamming

• How it works: GPS signals operate on higher frequencies such as the L1 band (1575.42 MHz). Jammers cover these frequencies by emitting noise signals, making it impossible for GPS devices to receive location signals from satellites.


• Impact: Navigation devices cannot determine location, and time synchronization may also be affected. Some devices that require precise positioning (such as drones or logistics tracking systems) will fail as a result.

Cellular Network Jamming

• How it works: Cellular networks (such as 2G/3G/4G/5G) use different frequency bands. Jammers block communications between base stations and mobile phones by emitting strong signals on these frequency bands.


• Impact: Mobile phones may not be able to make calls, send text messages, or use mobile data.
