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.

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.

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.

Corrections has quietly removed all cellphone jammers from prisons.

The technology, introduced in 2008-09 to prevent inmates using smuggled mobile phones, has cost more than $17 million.

But signal blocker have not been in use since June after being found to interfere with new prison guard safety systems.

When announcing their introduction, then Corrections Minister Phil Goff said cellphone blocking in New Zealand prisons was a major step forward that will stop prisoners committing further offences while behind bars.

Stuff recently obtained details under the Official Information Act about the number of cellphones seized from the 18 prisons run by Corrections over the past three years.

There were 626 cellphones and more than 750 cellphone-related items (such as batteries, chargers, SIM cards etc) found by Corrections staff between January 2023 and November this year.

When asked why inmates would be smuggling cellphones when the prison’s had the mobile signal jammer that should render them useless, Corrections chief custodial officer Neil Beales said the cellphone jammers were removed in June.

The jammers had been found to interfere with new safety systems such as Corrections officer safety alarms, he said.

Advances in cellular technology had also resulted in jammers becoming “increasingly obsolete”.

It was “only one of a number of tools used to stop cellphones being used in prisons” and a number of “more effective tools” remain in place, Beales said.

These include Cellsense devices, which detect a range of metals found in cellphones, alongside screening and x-ray capability as well as detection dogs.

“Some people in prison go to extreme and elaborate lengths to introduce contraband into prisons, and we are constantly working to stay one step ahead of new methods used to introduce contraband into our prisons,” Beale said.

Corrections was looking at new and emerging technology to complement systems already in place, he said, and had started introducing the use of full body imaging technology at a number of sites to detect contraband that has been concealed on or in a person’s body.

In 2018 Corrections admitted cellphone jamming technology created a communications blind spot near Rimutaka Prison, meaning residents of a child sex offender unit outside the wire could not be tracked on-site at the facility.

Cellphones could be used by inmates to put pressure on others outside the wire, or to co-ordinate drug deals, and other offending. In May this year nine prison staff at Rimutaka were suspended for alleged misconduct, including the smuggling of cellphones into the prison.

Drug and alcohol counsellor and criminologist Roger Brooking, who has been critical of the spending on jammers from the outset, said it was not surprising that Corrections had ditched the technology.

“They don’t work. They never have worked,” he said.

“What prisoners have told me is that they have always managed to find areas within the prisons where the jammer just doesn’t seem to operate. So prisoners have been able to continue making cellphone calls to conduct drug deals, talk to family or whatever.”

By producing a “no response” or cosine error, a laser jammer effectively obstructs the accuracy of a laser radar gun aimed at a vehicle by a police officer. As a result, the police officer is left uncertain about whether the vehicle is equipped with a laser jammer or if their aim is flawed.

A laser jammer is a gadget that produces a “no response” or cosine error when a police officer directs a laser radar gun at a vehicle. This error prevents the police officer from knowing whether the vehicle is equipped with a laser jammer or if they are not aiming correctly at the vehicle.

How to jam police lasers?

The effective defense against a laser requires the front laser jammers to provide protection for the headlights, license plate, and the reflective surfaces in their vicinity. Conversely, at the rear, the primary targets are the license plate and tail lights. Moreover, the center high-mounted stop light, backup lights, and vertical reflective surfaces are also vulnerable. It is noteworthy that even a tailgate-mounted spare tire/wheel assembly can be targeted, as evidenced by our successful attempt at hitting a Jeep Wrangler’s aluminum spare wheel from a distance of 2,500 feet.

Can you install a laser signal jammers on your car?

California Vehicle Code Section 28150 (Division 12: Equipment of Vehicles, Chapter 5: Other Equipment, Article 17: Jamming Devices) states the following:

(a) No vehicle shall be equipped with any device that is designed for, or is capable of, jamming, scrambling, neutralizing, disabling, or otherwise interfering with radar, laser, or any other electronic device used by a law enforcement agency to measure the speed of moving objects.

(b) No person shall use, buy, possess, manufacture, sell, or otherwise distribute any device that is designed for jamming, scrambling, neutralizing, disabling, or otherwise interfering with radar, laser, or any other electronic device used by a law enforcement agency to measure the speed of moving objects.

(c) Except as provided in subdivision (d), a violation of subdivision (a) or (b) is an infraction.

(d) When a person possesses four or more devices in violation of subdivision (b), the person is guilty of a misdemeanor.

(e) Notwithstanding any other provision of law, a person who has a valid federal license for operating the devices described in this section may transport one or more of those devices if the license is carried in the vehicle transporting the device at all times when the device is being transported.

Can police radar measure speeds or more than one vehicle?

The speed of multiple vehicles can be captured at once by dash-mounted police radars, usually up to two.

Today, radar systems have the ability to target multiple vehicles simultaneously, identifying the fastest vehicle in a group and the vehicle with the emest radar signal reflection at the same time. Nonetheless, visual confirmation by the officer is necessary to determine the fastest vehicle among those targeted.

Have you ever been the victim of a police laser gun and been ticketed for speeding? If your answer is yes, then you may want to take countermeasures to help you prevent such encounters. Well, your problem can be solved. Check out the tools that help prevent speeding tickets – defensive laser jammer!

By emitting a signal that interferes with the laser gun’s speed detection capabilities, a laser signal jammer is able to confuse the gun.

To comprehend this, it is crucial to have a clear understanding of how a laser gun operates. This device is utilized to aim a laser beam directly at your license plate or any reflective surface.

The development of laser jammers aimed to assist in the notification of laser speed traps.

Through the analysis of received traffic laser signals, laser jammers can effectively disrupt the source of the signal. Consequently, the source device fails to detect any activity and presents the operator with an unread or misdirected message.

The presence of an automatic shut-off feature is a fundamental characteristic of high-grade jammers, ensuring their immediate deactivation upon the detection and confirmation of a laser threat.

Uninterrupted laser interference can potentially lead to a confrontation with a law enforcement officer who is aiming at you but has not acquired the speed reading of your vehicle.

What are the advantages of using laser jammers?

Diminish the likelihood of accruing more speeding violations: Too many speeding tickets can result in the deduction of numerous points, putting your driver’s license at risk and causing you to waste your hard-earned money. For professional drivers, losing their license means losing their livelihood. Investing in a laser jammer is akin to taking preventive action.

Your radar detector let you down in this instance. A radar detector can warn you of a police laser gun aiming at your car. However, radar detectors are passive, and laser guns can measure your speed in less than half a second. This means that by the time you receive a warning, the officer may have already determined your speed. On the other hand, a laser jammer is active and prevents the laser gun from calculating your speed for a set period.

Although it may appear to be a walkie talkie at first glance, that unassuming little box holds far more power than one might assume. Once activated, a mobile phone signal jammer can effectively block all cell phone signals in the surrounding area. However, it is crucial to note that utilizing such a device is not only a violation of federal law but also carries the risk of a substantial $16,000 fine and potential incarceration.

The presence of talkative cell phone users on the SEPTA 44 bus in Philadelphia did not deter Eric. According to NBC 10, Eric would activate a block signal jammer to block out the conversations that he found bothersome.

“A lot of people are extremely loud, no sense of just privacy or anything. When it becomes a bother, that’s when I screw on the antenna and flip the switch,” Eric told NBC 10.

Eric stated that he was unaware of the fact that blocking a cell phone signal was illegal, considering it to be a “gray area.” He believed that it was only considered illegal when it pertained to blocking television or radio signals.

In spite of this, he did not seem particularly sorry for his actions.

He proudly admitted to NBC 10 that he is taking on the responsibility of enforcing the law independently.

The use of jammers, like the one employed in this situation, is against the law due to their potential to disrupt cell phone communication during emergencies and interfere with vital signals like police radio and other two-way radios.

Eric announced his intention to dispose of the jammer he had purchased upon learning that it was illegal, with ABC News estimating its cost at $300.

Yet, the key issue is that Eric is not the sole individual partaking in this jamming practice.

Prior to assessing the effect of a mobile phone signal jammer on laptop Internet access, it is crucial to comprehend the interference frequency band utilized by the jammer and the frequency band employed by laptops to access the Internet.

First of all, if the interference frequency band of the mobile phone signal jammer overlaps with the frequency band used by the laptop to access the Internet, it will affect the laptop’s Internet access function. Let’s first take a look at the interference frequency band of cell phone jammers. Due to the wide signal coverage of domestic operators and the wide range of application standards, mobile phone signal jammers must achieve the effect of blocking the entire network. Generally, they will effectively block interference for 2G, 3G, 4G band signals, WiFi, GPS, and Bluetooth signals.

Having identified the frequency bands that the cell phone signal blocker described above can interfere with, let us now turn our attention to the frequency bands that laptops utilize for Internet connectivity.

Laptops generally have two ways to access the Internet, one is wired Internet access, that is, Ethernet network port Internet access, and the other is wireless Internet access. At present, mobile phone signal jamming device cannot block or interfere with wired Internet access, so here we mainly describe the frequency bands for laptop wireless Internet access. According to the current classification of laptops on the market, wireless Internet access supports single-band and dual-band. The so-called single-band refers to only supporting WiFi2.4 frequency band to connect to the Internet, while dual-band supports WiFi2.4 and WiFi5.8 frequency bands to connect to the Internet. Most laptops only support single-band, and some that are more expensive or have more conscientious configurations will be equipped with dual-band Internet access.

The interplay between signal blockers and laptop computers’ working frequency bands becomes apparent to keen observers, who can readily recognize the potential disruption of laptop Internet access by mobile phone signal jammers.

Detailed requirements are broken down into the following situations:

1.The mobile phone signal jammer does not have a WLAN module and will not affect the wireless Internet access of laptops;

The mobile phone signal jammer supports the WiFi2.4 frequency band, which affects the wireless Internet access of single-band laptops but does not affect the wireless Internet access of dual-band laptops;

The mobile phone signal jammer supports WiFi2.4 and WiFi5.8 frequency bands, which will affect the wireless Internet function of the laptop.

Through the comprehensive understanding gained from the preceding explanation, we have obtained a clear answer regarding the potential interference of a mobile phone signal jammer on a laptop’s Internet access. It has been established that the laptop’s wireless Internet connectivity may be disrupted by the operation of a signal jammer. To ensure uninterrupted access, customers who utilize signal jammers for shielding purposes should consider equipping their laptops with Ethernet cables to establish connections with external network offices. This approach will enable them to achieve optimal performance in both aspects.

The NFL and federal law enforcement are on high alert for unauthorized drones after one caused a play stoppage at a playoff game two weeks ago.

Super Bowl LVIII will feature a tough defensive scheme that has nothing to do with a football. This one is about stopping drones.

The NFL and federal law enforcement officials are taking a hard line Sunday to keep players and fans safe from unauthorized drones at Allegiant Stadium in Las Vegas where the Kansas City Chiefs will play the San Francisco 49ers.

Unapproved drone flights have become a persistent problem for the NFL, as well as for other sports leagues and large public gatherings. The NFL said there were about 2,500 drone incursions near stadiums during the 2022-2023 season, an increase of about 90% from a year earlier.

The flights have sometimes encroached on televised broadcasts, including two weeks ago at the AFC championship game in Baltimore when an unapproved drone violated the restricted airspace. Federal prosecutors later charged a Pennsylvania drone pilot who said, according to the FBI, that he wasn’t aware of the flight restrictions.

Possible criminal charges and civil penalties await anyone trying something similar Sunday, officials said.

“So please leave your drone at home,” Cathy Lanier, the NFL’s chief security officer, said at a news conference Wednesday.

Most of the drones are operated by hobbyists seeking aerial video, according to experts, but especially at a high-profile event such as the Super Bowl, authorities said they’re also looking out for people with more nefarious intentions.

Homeland Security Secretary Alejandro Mayorkas said the incident two weeks ago was a warning.

“It does not require much imagination to understand the significant threat such an incident could pose,” he said at the news conference Wednesday. Although no one was hurt in that incident, he said, “what happened in Baltimore underscores the vital importance of the mission.”

Mayorkas added that there were no known credible specific threats to the Super Bowl or Las Vegas.

Federal law enforcement designates the Super Bowl as a top-tier security event, on roughly the same level as a presidential inauguration ceremony or a visit by the pope. Allegiant Stadium, where the teams will play, has a capacity of about 65,000 people.

Any stadium’s defense against drones has multiple layers, said Mary-Lou Smulders, chief marketing officer for Dedrone, a Virginia-based company. Its drone countermeasure technology is in use by the Las Vegas Metropolitan Police Department, which covers Las Vegas and its major stadiums.

“Like any security issue, the more layers you add, the safer you are,” she said. “The same applies to airspace security.”

The first layers, she said, are all designed to detect and track drones using at least three types of technology: radio-frequency sensors, cameras and radar. They have different strengths, she added: Radio-frequency sensors can distinguish between drones and other objects better than radar, while radar has a longer range and a camera can help determine if a drone is carrying a payload.

With a camera, Smulders said, “the most interesting thing to ask is: Is it carrying a payload, yes or no?” If it were, that “would dramatically affect your security posture.”

A second set of layers is designed to interfere with a drone’s flight, she said: “cell phone jammer jamming” or cutting off the radio communication between a drone and its pilot; hacking into a drone to take over control; and locating the pilot on the ground and arresting the person.

drone jammer Jamming and hacking are not usually available as security tools for an NFL game. Federal law restricts who can interfere with a drone’s flight, and in the United States, only a few government agencies including the Department of Homeland Security and the FBI have the authority to do so. Congress is considering legislation to change that but, for now, the federal government provides agents for high-profile events like the Super Bowl but not for a game on any given Sunday.

At a regular season game in Baltimore in November, play was delayed twice because of drone activity.

The NFL game stoppages are helping raise the profile of drone countermeasures, a growing industry that experts say will become more important as drone technology improves and becomes cheaper.

Allegiant Stadium has one advantage over Baltimore’s: It’s a domed stadium, with a roof to shield the game from anything overhead. But it’s not completely enclosed, Smulders noted: The stadium has 80-foot walls that are retractable if weather allows. The doors have usually been closed during games.

Still, the NFL is on higher alert for drones than it used to be. In 2017, a California man used a modified drone to drop leaflets on the 49ers stadium, authorities said. He then drove to nearby Oakland and did the same at a Raiders game. He later pleaded guilty and was sentenced to probation.

For Sunday, the Federal Aviation Administration has banned drones within a radius of 30 nautical miles (about 35 miles) of the stadium beginning one hour before kickoff. There have also been restrictions in place for additional events in Las Vegas the past few days.

Lanier has previously told NBC News that the NFL had a close call at the Super Bowl in Atlanta in February 2019, when an FBI team spotted a drone just before six Air Force F-16s were set to conduct a flyover before the game. The F-16s flew at a higher altitude to avoid a possible collision, she said.
