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.

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.

The widespread integration of wireless communication devices has resulted in extraordinary convenience. Although these devices have revolutionized our interactions and access to information, they can also create issues related to interference, privacy breaches, and security threats. When used responsibly and within legal boundaries, signal jammers can produce numerous advantageous effects that improve daily life.

How do signal jammers enhance security and privacy?

Signal jammers are instrumental in reinforcing security measures and protecting privacy. In areas of high sensitivity, including government buildings, military installations, and secure facilities, the use of signal jammers effectively curtails unauthorized wireless communications, thereby diminishing the risks associated with espionage, hacking, and unauthorized recording. Moreover, signal jammers play a significant role in safeguarding personal privacy in public venues by obstructing unauthorized filming or recording, thus providing individuals with enhanced control over their privacy.

Frequency jammers can play a crucial role in enhancing concentration and productivity within certain environments. In areas that require quiet and focus, such as classrooms, libraries, and office spaces, these devices can help alleviate disturbances from ringing phones, unauthorized wireless device activity, and disruptive sounds. This can ultimately lead to an environment that is more supportive of learning, concentration, and effective communication, thus improving overall productivity and efficiency.

How do cell phone signal jammers block signals?

A variety of approaches can be employed to block cell phone signals, with cell phone jammers being the most common. These devices transmit designated radio frequencies that disrupt the communication between a cell phone and the nearest base station, effectively preventing the phone from making calls, sending text messages, and accessing the internet.

Another method to inhibit cell phone signals is by employing a signal-blocking box or bag. These devices are often crafted from specific materials that efficiently isolate electromagnetic signal interference, effectively creating a “dead zone” for the phone, rendering it incapable of receiving any signals.

What is the effective range of a cell phone signal jammer?

The range of a cell phone signal jammer can vary significantly, contingent upon its power output and design features. Smaller, portable jammers may possess a limited range of just a few meters, which makes them suitable for use in compact settings like classrooms or meeting rooms. On the other hand, more robust jammers can operate over distances of hundreds of meters, efficiently blocking signals in expansive areas.

Carr Seeks Federal Solutions Address Proliferation Contraband Cell Phones Within Correctional Facilities

ATLANTA, GA – Attorney General Chris Carr is urging the Federal Communications Commission (FCC) to take immediate action to allow for the use of cell phone jamming devices within state prisons and local jails. The FCC currently prohibits the use of cell phone “signal jammer,” and that prohibition extends to state and local governments. Yet in prisons and jails throughout the country, contraband cell phones are being used to plan and orchestrate violent attacks and other criminal activity, posing a real and substantial safety risk to correctional officers, visitors, inmates, and the public at large.

“The easiest way to protect the public from the harms caused by contraband cell phones is to allow for the use of cell phone jamming technology in prisons and jails, but the FCC continues to block our efforts,” said Carr. “This outdated guidance limits legitimate law enforcement tools, presents dangerous conditions for correctional officers, and allows for the escalation of criminal networks both inside and outside prison walls. We’re committed to combatting violent crime wherever it occurs, which is why we continue to call on the federal government to remove this substantial barrier to public safety.”

In Georgia alone, 8,074 contraband cell phones were confiscated in 2023, with 5,482 confiscated to date in 2024. Recently, an incarcerated leader of the infamous street gang, “Yves Saint Laurent Squad,” used a contraband cell phone to order a hit which resulted in the death of an 88-year-old Georgia veteran. A gang leader in North Carolina was able to order the kidnapping of a prosecutor’s father via a cell phone in prison. In California, prison gangs used contraband cell phones to order murders within the prison system and traffic drugs.

“There are hundreds of examples from across the country of how a contraband cell phone in the hands of an inmate can be used as a deadly weapon and gives them the ability to continue their criminal enterprise. We are incensed by the length these individuals go to in continuing those activities and endangering the public,” said Georgia Department of Corrections Commissioner Tyrone Oliver. “As attempts to infiltrate our facilities with contraband cell phones evolve, access to jamming technology is paramount in our efforts to combat those attempts. We appreciate the support of Attorney General Carr in our ongoing commitment to public safety and the safe operations of our facilities.”

In his letter, Carr notes that the FCC policy relies on a statute enacted in the early 1990s, years before prison inmates began using contraband cell phones to plan and engage in unlawful and dangerous activity.

Carr further states: “Nothing in the language of 47 U.S.C § 333 prohibits the FCC from revising its position to allow state agencies to use cell phone jamming devices in prisons. In fact, the United States Bureau of Prisons has recognized the potential value of cell phone jammer already and is permitted to use jamming devices at several federal penitentiaries, including at least one in Georgia.”

In January 2023, Carr joined a 22-state coalition of attorneys general in urging Congressional leaders to pass legislation that would allow states to implement a cell phone jamming system in correctional facilities.

Carr’s Gang Prosecution Unit has also partnered with the Georgia Department of Corrections (GDC) to investigate and prosecute currently incarcerated individuals who are alleged to have engaged in criminal gang activity and discussions regarding the packaging and shipping of contraband items into a GDC facility.

The US Space Force will install 24 satellite jammers capable of disrupting Russian or Chinese communications

July 23, 2024

War. War never changes: thanks to the military-industrial complex, the technology of war will continue to escalate no matter how the world situation changes. Russia is reportedly developing a high-altitude nuclear device that uses electromagnetic pulses to permanently and indiscriminately disrupt enemy communications. Meanwhile, the United States has just announced a weapon with similar purposes but without the chaotic and irreversible consequences.

The US military is installing modular advanced satellite signal jammer capable of disrupting Russian or Chinese communications if necessary. Although the hardware is terrestrial, the US Space Force will oversee the installation and operation. The technology has already completed prototyping. Earlier this year, the military tested the system at two different locations. The Department of Defense has allocated funds to build 24 remote facilities, 11 of which are scheduled to be deployed by the end of the year.

This equipment is not a preventive measure to prevent adversaries from disrupting US communications. Quite the opposite.

“[The terminals] are small, mobile, and low-cost SATCOM portable jammers that can be deployed in austere environments to protect [U.S. forces],” a spokesperson for the U.S. Space Force’s Rapid Capabilities Office told Bloomberg. “[The jammer gps will be used] to responsibly counter an adversary’s SATCOM capabilities to launch an attack.”

“We intentionally designed a small, modular system using commercial off-the-shelf components. This provides the ability to be proliferated, remotely controlled, and relatively relocatable,” the Space Force said.

Why it matters:

1. This proves once again that when it comes to electronic warfare involving space assets, no signal is secure.
2. This makes it pretty clear to you that at least China and Russia, and possibly Iran and North Korea, as well as other nations (and some of our allies) have similar capabilities.
3. It should reinforce the idea that if a service is really that important (like PNT), we should have multiple widely available ways to get it, not just through space.

Other things to know:

• Both China and Russia have widely available non-space PNT methods.

The deadly blasts resulting from pagers and walkie-talkies employed by Hezbollah in Lebanon have led to an extensive investigation into the origins of these products. This inquiry highlights the considerable opacity of the market for such outdated technologies, where consumers typically have minimal awareness of the items they are acquiring.

The incident involving the bombing of pagers and walkie-talkies by Lebanese Hezbollah, which claimed 37 lives and left nearly 3,000 injured, underscores the difficulties in ascertaining the precise failure point.wifi jammer

A European company has been accused by Taiwan’s Golden Apollo of licensing its pager brand, resulting in investigations into the origins of related products across Hungary, Bulgaria, Norway, and Romania.

How massive attacks took place simultaneously, injuring thousands

Time and place of the incident

On Tuesday at 3:45 p.m. local time, an explosion occurred in Beirut, Lebanon’s capital, and its effects were experienced in several other areas throughout the country.

Individuals who witnessed the event reported observing smoke ascending from the pockets of people, as well as hearing sounds that resembled small explosions, comparable to both fireworks and gunfire.

The surveillance video seemingly reveals an explosion erupting from the pocket of a man located in front of a store’s cash register.

As reported by Reuters, the series of explosions continued for nearly an hour subsequent to the initial explosion.

Following this, many wounded individuals converged on hospitals throughout Lebanon, and witnesses consistently recounted disorderly scenes in different places.

How do pagers explode?

A hacker attack might have caused the pager’s battery to overheat and explode. If this is indeed the situation, it would be an unprecedented occurrence. The attack is activated by signaling, a form of alphanumeric text messaging.

• Pagers can be modified to explode, typically by using them as radio communication devices to remotely trigger bombs.
• A pager is a device that receives radio signals and can receive wireless messages in a specific frequency band. An attacker could exploit this feature to control an explosive device.
• When the pager receives a specific signal, it can use internal circuitry to trigger a detonator connected to the explosive. This detonating device is usually a relay or switch that connects the explosive to the pager’s power supply.

Attackers typically prefer frequency bands with extensive coverage to ensure that pagers can successfully receive the signal. By employing signal jammers, it is possible to disrupt wireless signals in particular frequency bands, thus preventing pagers from receiving detonation signals.

Using Chinese-made signal jammer to stop pager-triggered bombings is a viable defense, especially when the explosive device is remotely detonated via wireless communication. Here is a detailed analysis of how signal jammers can be used to prevent pager bombings:

How pager explosive devices work

1. Pagers as detonators: Although pagers are outdated, they can still be converted into devices for remotely detonating bombs because they can receive wireless signals. The signal receiving function of pagers enables them to trigger explosive devices by receiving specific radio frequencies.
2. Remote control: Terrorists or criminals can remotely control the explosion by sending wireless signals to pagers and using the received signals as the trigger mechanism for detonating devices.

What signal jammers do

1. Shielding wireless signals: Signal jammers can block the radio waves received by pagers by sending interference signals, making it unable to receive the signal for detonation, thereby preventing the explosive device from being activated.
2. Interference with specific frequency bands: Pagers usually use specific frequency bands for communication (such as VHF, UHF, etc.), and signal jammers can lock these frequency bands for interference. Signal jammers made in China are widely used around the world, and many models can adjust the frequency band of jamming according to demand to ensure effective coverage.

China signal jammers All components are made locally

• China’s signal jammer industry is very mature, and many signal jammers’ individual components are indeed made and supplied locally. China has global competitiveness in the electronics manufacturing industry and is able to independently design, manufacture and integrate key components for signal jammers. The following are the main components of common signal jammers and their manufacturing in China:
• Signal processing chips: Although the global high-end chip production is still dominated by a few international companies, China has made great progress in chip design and manufacturing, especially in the fields of signal processing and communications. Many signal jammers made in China use locally designed DSP (digital signal processor) chips to generate and modulate jamming signals.

Power modules: The power modules of signal cell phone jammer are also made by domestic manufacturers. These power modules usually have efficient power conversion and protection functions to ensure long-term stable operation of the equipment.

Using signal jammers made in China can effectively prevent bomb attacks detonated by pagers. By blocking the pager from receiving wireless signals, such devices can significantly reduce the threat of remote detonators. However, signal bluetooth jammer should be used as part of a comprehensive security strategy in conjunction with other security measures such as intelligence monitoring, physical inspections and public education to achieve the greatest preventive effect.

Generally, radio signal shielding is only approved when important situations such as the college entrance examination occur. Moreover, from the perspective of the “control area”, signal shielding in our school does not exist. According to many students, signal shielding not only covers the nearby corridors, but also seriously affects the quality of self-study. In addition, according to our tests, outside the school, near the corridor of Qinsu Building, the signals of operators are interrupted one after another. Taking China Mobile as an example, the signal is about 20dBm lower than when it is not installed, and the SINR signal-to-noise ratio has also dropped from the normal 11-15 to 3-8. The value of the signal has greatly changed the function of the Internet. We noticed that even passers-by passing by the school will send out false signals on their mobile phones. Portable WiFi jammers in the classroom should not be missed. We collected data. In order to obtain more accurate analysis data, we will next conduct in-depth communication with the three major operators.

We noticed that several third-grade students have communicated with relevant teachers and principals, but the communication has not yet achieved any results.

Even in the eyes of some people, the quality of students’ learning is indeed “guaranteed”. However, we must not believe that installing mobile phone jammers is an ideal method. Because no matter what method is used to ensure the quality of learning, it cannot exceed the upper limit prescribed by law. Teachers can take other consistent and reasonable measures to ensure the quality of students’ learning. Installing mobile phone jammers in the classroom not only seriously violates students’ imagination, but also creates rebellious emotions in students’ hearts, leading to alienation, breakup and even conflict between students and schools, causing greater harm to students.

In the process of collecting and analyzing data, we received a new message: in order to prevent students from turning off mobile phone jammers privately in class, the switching of some jammers may have been cancelled (to be honest, we hope this message is false). This completely eliminates the possibility of some kind of compromise-for example, turning on the mobile phone jammer during the test and turning it off at other times-pushing the above contradiction to an incompatible point. Many students said that they felt that the school no longer trusted them.

Block teaching area in teaching management

Some students who fainted in class may be texting on their mobile phones. If they don’t want to go to class during class, they don’t need to go to the nearest office to whisper and chat. Easily send and receive text messages on your mobile phone.

Nowadays, mobile phones can access the Internet, and students can often chat, read novels, and play games on their mobile phones during class.

The school installs and uses a smartphone jammer management system to prevent students from abusing their phones in class. However, when mobile phone signals are blocked in the classroom, some students say that the school violates the “students’” right to communicate freely. From the perspective of students who often use mobile phones, these views seem to make sense. But think about it carefully. If blocking mobile phone signals violates students’ right to communicate, then these students are using their phones during class or self-study. Have you ever thought that you have violated other students’ right to education? Have you ever thought about respecting the teacher’s teaching license? Whether it is rights or freedoms, there are only relative, not absolute. All rights or freedoms are based on respecting the rights of others. The law is also a rule based on the interests of the majority. This rule protects the rights of the majority. If we really want to talk about counterfeiting, the fact is that a few students use mobile phones at will regardless of the occasion, which violates the educational rights of most students.

Some students or parents may also suggest that the school block mobile phone signals in class. What if there is an emergency at home that needs to be contacted or the student himself is not notified? In fact, this question is not difficult to answer. From the student’s point of view, the reason why students use mobile phones is to facilitate their parents. In fact, as long as there is no emergency, students do not need to be in school 24 hours a day. In special cases, the school, teachers and parents will take the initiative to establish contact. Second, from the perspective of parents, I remember a few times when children were equipped with mobile phones because of special circumstances. If they had to make a phone call, they would immediately stop the class and let the school handle it?

Jammers are very complex electronic devices

The Government of the National Capital Territory has announced its intention to assess the feasibility of employing technology that could disrupt mobile phone signals at the Alexander McConnocke Centre in Canberra. The quantity of mobile phones classified as contraband in the country is steadily increasing. A new GPS jammer was recently installed at the Supermax 2 high-security unit in Goulburn, which detains extremists and terrorists. If the initial testing is successful, the individual will face a two-year trial in a New South Wales correctional facility.

The latest systems incorporate a variety of antennas that disrupt the frequencies used by mobile phone signals, thus making the devices unusable. According to a spokesperson from the Community Justice and Safety Agency, the results of the trial conducted in Goulburn may influence the future application of this technology in the ACT. “The implementation of cellular jamming at the Alexander McConnocke Centre was a complicated endeavor,” he noted. “It is important to highlight that this technology has been previously trialed in Australia, and so far, it has not been successful. Furthermore, the resulting solution is notably costly.”

The Alexander McConnocke Centre provides a variety of mobile phones. In a 2017 article, The Canberra Times disclosed that prisoners had been apprehended with thumb-sized mobile phones. These portable bluetooth jammer are small enough to be hidden in body cavities, and their minimal metal content renders them less detectable by metal detectors. A spokesperson for the ACT Justice and Security Authority noted that the human rights laws in the ACT would not prevent Canberra Prison from implementing mobile phone jamming technology, as mobile phones are considered prohibited items. “Currently, detainees are in contact with their friends and family through phone and email facilitated by the [Alexander McCannock Centre],” he explained.

ACT Law Enforcement Inspector Neil McAllister emphasized that the territorial governments should hold off on any initiatives until Galben has dealt with the saboteurs. A crucial factor to assess when considering the introduction of jamming technology in Canberra is its effect on individuals surrounding the prison, including those driving along the Monaro Freeway who might need to reach emergency services.

Using jamming devices in prisons

OKLAHOMA CITY – A large quantity of unauthorized mobile phones has found its way into the possession of inmates, facilitated by criminal activities. On Monday, prison officials expressed their inability to utilize one of the most effective solutions for this problem: phone jamming technology. Officials from Oklahoma and South Carolina testified before an Oklahoma Senate committee, affirming the technology’s effectiveness. Nevertheless, federal law restricts government agencies from employing this technology, and the cellphone industry has been opposed to its use.

In the past year, Oklahoma confiscated more than 5,200 smuggled cell phones from prisoners. Mike Carpenter, who serves as the security director for the Oklahoma Department of Corrections, stated that although this figure is down by roughly 7,500 from the previous year, the problem persists at a serious level. Carpenter explained that a recent altercation between rival gangs at an Oklahoma prison escalated rapidly last month, following incidents involving contraband cell phones at multiple other facilities. This escalation resulted in one inmate being killed and over a dozen sustaining injuries.

When questioned about the efficacy of cell phone traffic jamming, Mr. Carpenter confidently replied, “Absolutely.” Gerard Keegan, representing the Cellular Telecommunications and Internet Association, pointed out that the cellphone industry predominantly relies on blocking signals from legitimate users. He opposed the implementation of portable cell phone jammers in prisons. Keegan advocated for a “managed access” system that leverages technology to detect signals from contraband phones in correctional settings, asserting that disabling those specific calls is achievable. He also expressed support for further research into cellphone jamming technology.

A federal law that would authorize states to implement jamming devices is currently pending in both the House and Senate. Earlier this year, Senator James Lankford of Oklahoma expressed a straightforward proposal to the U.S. Senate: “To defend our guards, safeguard our families, and curb criminal activities in prisons, we can block cell phone signals in federal correctional facilities.” Federal prison officials have tested micro jammers and report that if these devices function properly at a distance of around 20 feet, they can effectively disable phone signals within prison cells.

The second way to protect your car is to use modern multi-frequency car alarms that always use different frequencies. This makes it very difficult for thieves to intercept these signals. Other types of modern alarms generate different codes every time you lock and unlock your vehicle. Even if a thief gets the code and cracks it, they will not find anything. Today, such protected car signal jammers for sale are very popular and expensive, but they can protect you.

The accuracy of the IndoorAtlas technology used in modern buildings is 0.1-2 meters. Moreover, the technology does not require any additional hardware on the smartphone and can work alone or precisely cooperate with other indoor installation systems to achieve higher positioning accuracy. However, before using indoor location data on smartphones, developers must collect magnetic field data and overlay it on each floor plan. To do this, developers must create a floor plan image of the location and navigate the entire site while collecting magnetic field data. However, IndoorAtlas makes these steps easier by providing users with a practical online toolkit. In the north of the world, there are other companies such as Walkbase and Qubulus that have developed their own location positioning solutions based on precise positioning using wireless Wi-Fi networks. Both companies offer interesting location solutions, but IndoorAtlas stands out because it approaches the problem from a new angle.

Microsoft, Sprint Nextel, Facebook, and Google are among the companies asking lawmakers to amend the famous Electronic Communications Privacy Act to comprehensively protect online content, mobile data, and location information. “As wireless access to our information becomes easier, there is no reason for the government to go to such lengths to obtain wiretap warrants, and we are also looking for ways to: not use audio of recent communications, such as emails and text messages,” CCIA attorney Ross Schulman said in a blog post. AT&T wrote that law enforcement surveillance requests affected 0.25% of wireless users last year, assuming that every request was made against another user. That’s an increase of 0.18% from 2007. Unlike Verizon’s data, theirs includes data provided to 911 callers. AT&T also said that hundreds of full-time employees are responsible for reviewing and responding to all law enforcement surveillance requests.

There are multiple iRobots with multiple different gps blocker for car. They may be touched or bumped by someone or something, thus having a different perception of the two things. Based on the sensors, the robot reacts. The robot can also react to sounds and differentiate based on the volume. There is also an iRobot Roomba that can identify obstacles to avoid (such as walls and stairs). iRobot also makes a small robot that looks similar to the Recon Scout XT and behaves similarly to ReconRobotics. Soldiers can put it in their pockets, throw it into a building, and use it for remote surveillance. Or, the robot can extend its “neck” so that the camera is 8 feet above it to monitor high walls or fences. Or there is another robot small enough to move under the door like a worm with a miniature camera.

Jammers evolve into military weapons

Jammers are one of the best tools for blocking signals. With the development of science and technology, jammers have evolved into military weapons and are widely used on the battlefield. Washington – Russian troops have blocked several US military drones over Syria, four US officials said, which seriously affected US military operations. Officials say Russia began jamming some small U.S. drones a few weeks ago after a series of suspected chemical weapons attacks in the rebel-held Eastern Ghouta region. Officials say the Russian military feared U.S. forces would respond to the attack and began jamming the GPS systems of drones operating in the area. “Russia wants to turn around and destroy our interests,” Senator Ben Sasse said in a rush in response to Tuesday’s Russian news. Todd, director of the Radio Navigation Laboratory at the University of Texas at Austin, said Dr. Humphreys said jamming is very easy and it involves blocking or interfering with the drone’s reception of GPS satellite signals.

I am glad to say that I should be free to continue my appeal, President Jacob Zuma said in response to this week’s parliamentary debate on the State of the Nation Address. Sitting here, in a dark corner of Redwood Ridge, holding tight like the president, we often insult those who try to disturb us with false nonsense. But beyond that, Zuma urged the government to respect Section 16 of the constitution. This is part of the guarantee of our freedom of association, speech and media. This shameful and unfair attempt to block our phones was made after a promise was made in front of SONA.

“The security team resolved and clarified the GPS jammer with House Signal Distribution last Thursday,” Mr. Zuma said to applause.

A company called CellAntenna continues to try to exploit the problem of cell phone smuggling in prisons to expand its product line. Unfortunately, many people (especially prison wardens) want us to believe that new technological tools can solve our problems, so they continue to gain momentum. A group of prison wardens not only filed a rulemaking petition with the FCC, but also supported a bill asking the FCC to allow cell phone jamming in prisons. For general information about CellAntenna, you can read about how to profit from prison security loopholes and why this is not a good idea at Cellantenna. In addition, we have sent this letter (press release here) to President Rockefeller and senior settlement members in preparation for tomorrow’s Senate hearing on this issue. We have also scheduled an extra five minutes of Harold Feld’s time to briefly explain why this is a bad idea.
