The FCC says illegal devices that block cell phone signals could pose a security risk.

The FCC has noticed a rise in people selling "jammers." The devices can block cell phone calls, text messages, Wi-Fi networks and GPS systems and could be used to cause chaos in public places.

The small, battery-powered devices can be used to create "blind spots" in a small area (usually about 30 feet) and have been used by movie theaters, restaurants and schools to prevent people from using their phones. But they can also cut off 911 calls, interfere with navigation near airports and have been used to jam radio communications near police stations. FCC officials say they have noticed an increase in the flow of jammers, which are banned by federal law, into the U.S. Many of the cheaper versions, which sell for as little as $25, are imported from Asia, according to the agency.

It is illegal to sell, advertise, use or import jammers under the Communications Act of 1934, which prohibits blocking radio communications in public.

Earlier this week, the FCC issued subpoenas to eight individuals and companies that posted ads for jammers on Craigslist.

The FCC said cities including Orlando, Philadelphia, Austin, Mississippi, Charlotte, North Carolina, Washington, D.C., Cincinnati and Corpus Christi, Texas, advertised jammers on the site. Officials said they do not believe the cases are related.

"Simply posting an ad for a signal jammers on a site like Craigslist.org is a violation of federal law. Signal jammers are contraband for a reason," Michele Ellison, director of the FCC's enforcement bureau, said in a statement. "One person's moment of peace or privacy could jeopardize the safety and well-being of others."

According to the citations, most sellers advertised the jammers as a way to take an "undisturbed nap" on the bus, quiet a classroom or keep your area "free of interference," without mentioning the more nefarious uses the devices could be used for.

"We are increasingly concerned that individual consumers operating jammer devices do not appear to understand the serious consequences of using jammers," one of the citations read. "Instead, these operators mistakenly believed that their illegal operations were a matter of personal convenience or should be excused."

But the FCC said at least one seller appeared to know that jammers were contraband.

Keith Grabowski allegedly advertised on Philadelphia Craigslist for sale a "cell phone blocker, wifi blocker" for $300. In his ad, he said that "due to the nature of this item, we are revealing very few details," that the jammer was "not a toy," and that "I just wanted to get rid of it as quickly as possible."

"The nature of the ad suggests that Mr. Grabowski knew about the sensitive and/or illegal nature of the equipment he was selling on Craigslist," the citation reads.

People who receive the ticket have 15 days to remove the ad from the site and provide the FCC with information about where the jammer was purchased and to whom it was sold. Simply posting an ad for the sale of a jammer could result in a fine of more than $100,000.

The FCC has set up a "jammer tip line" for people to report to the agency people who may be selling or using jammers.

"We intend to take increasingly tough enforcement action against offenders," Ellison said. "If we find you selling or operating a jammer, you will be punished."

Expanding the scope of cell phone jammer applications

Cell phone jammers were initially created for law enforcement to intercept messages from terrorists and criminals. Over time, they have undergone significant advancements. Nowadays, they play a crucial role not only in combating terrorism but also in various official and civilian applications. Their capability to block communications as a precautionary step against organized crime and to disable remote-controlled explosive devices makes them essential in contemporary security measures. Furthermore, there have been instances where signal jammers have prevented attempts to assassinate prominent figures, underscoring their vital function in high-risk security situations.

Technological advances enhance jamming capabilities

The efficiency of cell phone jammers is attributed to the sophisticated technology powering them. These gadgets emit precise signals that disrupt the functioning of the remote-controlled receiver, thus thwarting the implementation of any programmed instructions. It is crucial to note that this interference is limited to a specified zone, guaranteeing that devices beyond this shielded region remain unaffected. This accuracy is vital for upholding uninterrupted communication across a broader expanse while safeguarding the intended area.

Jammers employ uniquely coded signals to trick GSM device receivers, stopping mobile phones from linking up with their respective base stations. This advanced method guarantees that any effort to communicate through a cell phone within the jammed area is successfully disrupted, while authorized communications beyond the jammed area continue without interruption.

Applications Beyond Terrorism

Educational Institutions:
- Cell phone jammers are increasingly used in educational institutions to prevent cheating in exams. By blocking signals within exam rooms, authorities can ensure a fair exam environment.

Prisons and Detention Centers:
- In detention centers, jammers are essential to prevent inmates from making unauthorized calls, which could coordinate criminal activity outside the facility.

Corporate Security:
- Companies use jammers to protect sensitive information during high-level meetings, ensuring that no unauthorized recording or transmission occurs.

Public Events and Venues:
- During large public events such as concerts or sporting events, jammers can prevent disruptions and ensure the safety of attendees by blocking potential threats such as remote control devices.

Hospitals:
- In medical settings, jammers help maintain security in areas where cell phone signals could interfere with sensitive medical equipment.

It is evident that cell phone jammers offer numerous advantages; however, their utilization necessitates a careful balance between ethical and legal factors. The deployment of jammers is subject to regulations that differ across countries and regions. In numerous locations, their usage is restricted to authorized individuals and specific situations to prevent any potential abuse and guarantee uninterrupted access to emergency communications.

With the continuous advancement of technology, it is expected that cell phone jammers will undergo further improvements. These future enhancements may involve refining the targeting capabilities to minimize any unintended disruptions, enhancing the portability for quick deployment in dynamic scenarios, and strengthening the encryption to ensure that jamming signals remain impenetrable.

Cell phone jammers have transformed from a niche law enforcement tool to a versatile device with widespread use in security, privacy, and public safety. By leveraging advanced technology, these devices play a vital role in protecting against threats ranging from terrorism to cheating on exams. However, their use must be strictly regulated to balance security needs with individual rights and freedoms. As we move forward, the continued development of jamming technology promises to enhance our ability to protect and secure society from emerging challenges.

Dissatisfaction plays a vital role in the advancement of individuals, societies, and human civilization. While an excess of discontent can be detrimental, a moderate amount of dissatisfaction can prove to be advantageous. If everyone is content with their circumstances, there will be no impetus for progress, ultimately resulting in the regression of humanity. Today, we will discuss the importance of discontent in the innovation of cell phone signal jammers.

The fundamental role of a cell phone jammers is to prevent unauthorized communication signals from being transmitted when required. This device is especially beneficial for individuals working within government and correctional institutions. Nevertheless, it is crucial to acknowledge that signal jammers can potentially disrupt communications, thereby posing a substantial security concern.

The necessity for security in certain facilities is evident. A prime example is military establishments that strictly prohibit any form of communication without prior approval.

Cell phones play an important role in our daily life. Why are there cell phone blockers now? Dissatisfaction is dissatisfaction, dissatisfaction with the improper use of mobile phones in some formal occasions. Discontent is also a driving force of human civilization as a whole. It can be said that in primitive society, science came into being because ancestors were not satisfied with their understanding of the world, and technology came into being because ancestors were not satisfied with simple manual labor. This curiosity and desire, in fact, also led to the prosperity of technology later.

Use jammers to prevent interference and block unauthorized communications

To maintain uninterrupted communication, the use of a signal jammersis necessary to enhance your lifestyle. Many countries have restrictions on the personal use of cell phone jammers. It is advisable to familiarize yourself with the laws in your region. Some individuals resort to installing jammers, particularly cell phone jammers, to prevent signal interference. If permitted by the laws of your country, you can obtain a valuable jamming device.

Whether it occurs during a class, conference, presentation, or religious gathering, an untimely phone call can cause considerable disturbances. To address this issue, the utilization of cell phone signal jammers can effectively prevent such interruptions. By employing these devices, interference and unwanted calls can be blocked, granting you the authority to maintain a peaceful environment.

Have you faced this situation previously? The phone continued to ring, but no one paid attention to the disruption. You exclaimed, "Please switch off your phone." Regrettably, your plea went unheeded. In any sizable crowd, instructing people to silence their devices simply doesn't suffice. There will always be a significant number who opt to keep their phones on for one reason or another. The solution lies in a cell phone jammer.

The question of whether this indicates a more significant societal concern can be subject to discussion, but the fact remains unchanged. Even during funerals, it is inevitable that occasional phone calls will interrupt the silence or be made for prayer.

Regardless of the scenario, the signal jammer can obstruct the necessary frequency for the phone to receive calls, ultimately preventing the phone from ringing.

The individual who fitted a laser jamming device in his commercial vehicle to evade speeding fines has received a suspended prison term, been instructed to pay a fine of £3000, and subjected to a two-month curfew.

Jason Moore was convicted by a jury at Swansea Crown Court for obstructing justice by installing a Laser Star jamming device on a VW Transporter van to obstruct a laser speed camera operator from Dyfed-Powys Police in determining the vehicle's speed.

James Hartson, the prosecutor, informed the court that in September 2018, the van was observed traveling at a high rate of speed as it neared the speed camera near Nantyci Showground on the A40, St Clears, heading towards Camarthen.

The camera operator encountered an error message while trying to measure the speed of the vehicle. Despite this, the operator had received training from Road Safety Support experts to identify the specific conditions that could trigger such an error message.

Dyfed-Powys Police, as part of Road Safety Support, enlisted the expertise of Steve Callaghan, a forensic video analyst and laser jammers specialist employed by the company.

Mr. Callaghan received a copy of the video and verified the presence of a suspicious device in the footage. Additionally, he observed that the laser signal jammers emitted light from the van's grille while error messages were being displayed by the laser speedmeter.

Following Mr. Callaghan's initial assessment and recommendations to Dyfed-Powys Police, the van was retrieved in order to conduct testing on the device and gather evidence.

A comprehensive report was compiled detailing the examination results and the circumstances surrounding the incident, during which the speed could not be determined. Road Safety Support determined that the van was traveling at a speed of 72 mph, exceeding its maximum permitted speed of 60 mph.

Mr. Moore stated that he was unaware of the Laser Star jamming system's ability to interfere with the speed measurement feature of a police speedmeter. He asserted that he purchased the device specifically for its parking sensor function.

Mr. Moore selected David Winstanley, a former police collision investigator, who asserted his proficiency in laser and video systems, to serve as his expert witness.

Mr. Winstanley emphasized that the Laser Star should be marketed as a 'parking sensor' rather than being viewed primarily as a laser jamming device.

Mr. Callaghan clarified that utilizing a laser beam for identifying parking obstacles was completely unsuitable and mostly ineffective. He pointed out that a parking sensor does not have to be set to disrupt a laser speedmeter in any circumstance. Additionally, the Laser Star is advertised as being able to disrupt speed cameras in its instructions and marketing materials, which is not a feature of a parking sensor.

Mr. Moore further mentioned in his explanation that the security firm he was employed by required staff to cover the costs of any harm inflicted on company vehicles. He argued that he installed the device to minimize the likelihood of damage.

Moore was convicted by a jury and received a sentence at Swansea Crown Court on October 18, 2021.

Judge Vosper QC deemed Moore's defense as baseless, expressing no astonishment over the jury's dismissal of it.

Moore received a suspended 32-week custodial sentence, which will remain in effect for a period of 2 years. Additionally, he has been instructed to settle costs and fines amounting to £3,000, and a curfew lasting two months has been imposed upon him.

Can police tell if you have a laser jammer?

The utilization of a lidar gun by the police, directed towards a vehicle, will result in the device displaying either "no response" or cosine error. In the event of such an error, the police will be unable to determine whether the vehicle is equipped with a laser jammer or if they are simply not targeting the vehicle accurately. Consequently, this grants the driver an opportunity to modify their speed before the police can retrieve the data once more.

Since police need to be stationary and able to see a vehicle at close range without cover for lidar to work properly, if police receive a false response the first time they fire their lidar gun, the targeted driver will likely have time to adjust his speed when out of range. Lidar is most often used by motorcycle police or identifiable patrol cars, who use it most effectively on major roads, which limits when and where they can be used. In the case of heavy traffic, the police lidar gun is very effective at focusing on the vehicle and instantly calculating its speed, distance and direction.

A Fairhope man was charged last week with interfering with a 911 dispatch call, and new court documents show a similar thing happened at the same apartment building a month earlier.

The residents of the apartment were the first to know and called the police.

On June 6, Trenton Lisak, 31, allegedly interfered with 911 dispatch calls from the Mobile Police Department, Fire Rescue, the sheriff and even the Metropolitan Jail in the downtown entertainment district. Police say Lissak carried out the well-planned attack from an apartment in downtown Mobile.

"People with these kinds of resources obviously cause a lot of concern," said Michael Kraus, a resident of the apartment building.

In a moment of life and death, this can be catastrophic

Officials at the Mobile County 911 Center told FOX10 News that detectives traced the disturbance to the 9th floor, where they found Lisak as well as the black market mobile jammer.

Now, new court documents show that a month ago, multiple tenants in the building complained that Wi-Fi and phones were not working.

Investigators said at the time that AT&T had gone to the apartment where Lissak was staying and told a tenant to stop interfering. After the disruption stopped, it began again on June 6. At that time detectives found the strongest signal jamming at the same door.

Kraus, who lives on a nearby floor, said the poor Wi-Fi signal affected his remote work for weeks

"Things are moving slowly, and I can see that there are issues like connectivity issues and interference," Krause said. "To me personally, it was very different, but after he left, or in this case, I guess arrested him, everything seemed to go back to normal." Since you told me it was on the 9th, that must explain a lot."

Court records show that Lissak is no stranger to the law. He was jailed for unrelated crimes, including a burglary in Baldwin County.

911 service director Charlie McNicol said Lissack's motive was unclear.

"He could have a variety of reasons, like he just likes to watch chaos, or he has mental issues, or unfortunately, he could be planning a major event and want to ensure public safety by interfering with communications," McNicol said.

Other residents told FOX10 News reporter Lacey Beasley that they saw SWAT officers enter the building the day Lisak was arrested.

But employees at the apartment said he did not live there.

The FBI is investigating.

A Chicago resident, aged 63, was formally charged on Tuesday for employing an illicit device to find solace during his commute on the CTA.

The man has been accused of interfering with cell phone signals before, as reported by Audrina Bigos of CBS 2, and the high number of complaints about dropped calls has raised concerns.

After being charged with a felony for using a signal jamming device, Dennis Nicholl, a certified public accountant, left the jail dressed in a ball cap and business casual attire.

The device caught Keegan Goudie's attention, leading him and his brother to write a post on thesixthirty.com after encountering it on the CTA Red Line.

Chas remarked that his behavior suggested he was engaging in suspicious activities, and that the device seemed inappropriate for him to possess.

Online retailers offer cell phone blocker for sale at prices that vary between $30 and $300. Federal regulations strictly forbid the sale, purchase, or operation of these devices. These jammers have the ability to block cell phone signals, police radio transmissions, and emergency calls.

Keegan expressed the belief that it serves as evidence of what any person can achieve in relation to security and the menace of terrorism in a metropolitan setting.

Over the course of several months, the Chicago Police diligently probed into complaints regarding dropped calls along the Red Line. Subsequently, a 911 caller brought attention to the now infamous Nicholl. He was apprehended by undercover officers on a CTA platform on Tuesday and is now confronting a felony charge.

According to attorney Charles Lauer, there was no malicious intent to cause harm to anyone.

In an attempt to seek tranquility, Nicholl's lawyer argues that he resorted to employing signal blocker due to his frustration with the incessant presence of people using their cell phones.

As per the FCC, those who employ cell phone jammers risk imprisonment and hefty fines. The fines can amount to $16,000 for each violation or reach as high as $112,000 for a single use of the device.

Wednesday night saw Nicholl being released from jail after securing bond.

What’s the context?

US prison officials harness new technology to crack down on contraband cellphones but some still want powers to jam signals

South Carolina programme shuts off more than 800 phones

Federal action on broader signal jamming tech seen as unlikely

Activists raise privacy, rights concerns for prisoners

RICHMOND, Virginia - As director of South Carolina's Department of Corrections, Bryan Stirling believes he knows what is needed to make the state's 21 penal institutions safer while also protecting people outside the prison walls.

Ideally, Stirling would like to have the power to jam phone signals from the state's prisons to tackle the scourge of illegal cellphones being used to facilitate crimes ranging from sex trafficking to murder-for-hire and drug dealing.

But this action has been prohibited under federal law for decades, and there is no immediate sign of change despite numerous appeals from law enforcement officers across the country, including a letter from top state prosecutors to the leaders of Congress last year.

With no movement likely in the near future, South Carolina opted for a pilot programme that allowed authorities in Lee Correctional Institution to identify and shut down contraband cellphones. More than 800 phones have been shut off at Lee since last July, out of an inmate population of about 1,100.

"We call it a pilot, but it's basically the system in there now," said Stirling. "We are using this technology in Lee and we will continue to use this technology until we can secure the money to do it everywhere."

Cellphone jammers not enough to block calls from prisoners

This is the view of senior prison officials who tell the Sunday Express that even though signal blocker (which they say are operational) are used to block signals from cellphones within the prisons, other interception technologies are needed for the system to be effective.

“Cellphone jammers are being used. But they need to be in use with other technologies like Wi-Fi jammers to be truly effective. We can see this in other jurisdictions. But it’s yet to be properly utilised here.

“So you will have prisoners with cellphones and tablets who cannot make calls. But they can use either the phone’s data, or if they have access to a hot-spot device or a Wi-Fi box, they will be able to make calls via social media apps. These include things like WhatsApp, Facebook and Instagram. So there is still the issue of communication with the outside world. Communication is still being made.

“In other jurisdictions, you will see the cellphone jammers being used with other interception devices to determine the frequencies used by these devices, and then target those specific frequencies. If this is not done, then it’s almost like spinning top in mud,” a senior source in the Prison Service explained yesterday.

When a police officer aims a laser radar gun at a vehicle, a laser jammer comes into play by generating a "no response" or cosine error. This error prevents the police officer from determining whether the vehicle is equipped with a laser jammer or if their aim is inaccurate.

A laser jammers is a mechanism that triggers a "no response" or cosine error message when a police officer points a laser radar gun at a vehicle. This error message prevents the police officer from ascertaining whether the vehicle is employing a laser signal jammers or if they are simply not aiming correctly at the vehicle.

How to jam police lasers?

The protection of headlights, license plate, and surrounding reflective surfaces is crucial for the front laser jammers to effectively counter a laser. Conversely, at the rear, the primary targets are the license plate and tail lights. Furthermore, the center high-mounted stop light, backup lights, and vertical reflective surfaces are also vulnerable. It is worth noting that even a tailgate-mounted spare tire/wheel assembly can be targeted, as exemplified by our ability to successfully aim at a Jeep Wrangler's aluminum spare wheel from a distance of 2,500 feet.

Can you install a laser jammer 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?

It is possible for dash-mounted police radars to record the speed of more than one vehicle concurrently, usually two.

Nowadays, radar systems have the capability to target multiple vehicles concurrently, identifying both the fastest vehicle in a group and the vehicle with the emest radar signal reflection. Nevertheless, visual confirmation by the officer is essential to ascertain the fastest vehicle among those targeted.

In 2011, the Payson Police Department believed they were acquiring a cell phone jammers from a government program supplying surplus military equipment to law enforcement agencies. However, they ended up with a smokescreen device from a U.S. Navy ship.

“The ‘Electronic Countermeasures’ were supposed to be cell phone jamming devices. However, what was sent were smoke machines off of a naval ship,” Chief of Police Ronald Tischer said in an email to Arizona Mirror. “So, we are in the process of sending them back. They were never used and have been in storage since 2011.”

The Mirror reached out to the Payson Police Department after analyzing data published by the Defense Logistics Agency about military equipment sent to local law enforcement agencies across the country. The department obtained two items listed as “electronic countermeasures” in 2011 both valued at roughly $4,800.

Company offering cell, drone and other jammers is fined $35 million

Despite the possibility of not recovering the fine, the Federal Communications Commission announced yesterday that it has imposed a penalty forfeiture order of $34.9 million on Chinese electronics manufacturer and online retailer C.T.S. Technology for selling signal jamming devices to American consumers.

Radio frequency transmitters known as "jammers" are deliberately designed to obstruct, disturb, or impede wireless communications, including cell phone calls, GPS systems, Wi-Fi networks, and emergency communications.

C.T.S. Technology has been subjected to an investigation by the FCC's Enforcement Bureau, resulting in the Commission's proposal to impose a fine of $34,912,500. This penalty is being considered due to the company's marketing of 285 jammer models within the United States.

The company was directed by the FCC to guarantee that its marketing adheres to federal law. Despite not responding to the proposed fine, referred to as a "Notice of Apparent Liability," the company has subsequently implemented various measures to align its marketing practices with the U.S. laws that prohibit the marketing, sale, and importation of signal jammers.

The Commission did not receive any evidence from C.T.S. Technology to challenge the findings of the proposed fine. Therefore, yesterday's decision, which was a formal forfeiture order, upheld the full proposed fine against the company.

But collecting that money may be difficult.

Due to C.T.S. failing to acknowledge receipt of the NAL, the FCC reached out to the Chinese government to issue the NAL, as allowed by international law.

However, China's designated service affairs agency disregarded the agency's request and concluded that a forfeiture filing was suitable.

C.T.S. must make payment within 30 days. The FCC has not disclosed any further steps that will be taken in the event of non-payment.

Bear will make an effort to clarify the intricacies implicated. Initially, there arises the issue of what and how they are obstructing. Bear will assume that they are causing interference instead of engaging in hacking, as the latter involves an entirely separate affair.

If a human encounters a situation where the network connection to Ubear is lost while the phone, data service, and GPS remain functional, it is probable that the issue lies with the Ubear app. There is no need to assume that nearby drivers are causing interference. When Ubear experiences a loss of coverage, which is frequent in its mountainous environment, no special measures are required to restore access to U/L. This appears to be a problem related to the human's phone.

If human is being jammed, most off-the-shelf (all illegal) jammers are going to be broadband and omnidirectional. In fact, bear finds in a search that such devices advertise their broadband capability. So any driver using one is going to potentially take out not only cell service but also TV broadcast (which still uses the parts of the good ol' UHF band that haven't been sold to the cell providers) and possibly GPS, and maybe even local 2.4GHz services (wifi, bluetooth), within the range of cell phone jammers. These devices aren't exactly subtle and many of them have a stupid amount of broadcast power. Bear saw one device with 8W transmit; in comparison, bear's marine radio normally uses 1W, but if bear is about to drown (bear can swim quite well) and needs the Coast Guard to come from miles away to save bear, bear can kick it up to 25W which gives range of up to 60 miles (the Coast Guard has bigass antennae to receive).

As a result, signal jammers will effectively sabotage their own ability to receive any signal, thereby disconnecting themselves from the network.

Moreover, it is essential for a hotel to allocate a specific timeframe, typically lasting around an hour, for their busy checkout period. In a fixed location, this duration is set to a minimum of 15 minutes. This timeframe far exceeds the duration in which the irresponsible driver, who was apprehended for jamming a particular cell tower during his morning commute, would have been causing disruptions. If individuals are actively interfering with GPS signals, it is likely that military interests would also take notice. Without a doubt, any driver in Florida is never too far away from a Coast Guard asset.

It is conceivable that they possess a low-power device designed to function within a short distance. Evidently, they are aware of the human's habitual napping spot and take advantage of this knowledge. By positioning themselves directly next to the human, they momentarily disrupt their device's signal, exploiting the human's subpar phone that is susceptible to such interference. Wonderful! Now they simply need to repeat this procedure with the multitude of other ants present, as they continue to drive around.

All to earn $0.60/mile on a ride?

Version 1: Bear suggests that individuals maintain the operation of an additional service, like Pandora, while they take a nap. If Pandora does not encounter the same issues, it indicates that the person is not experiencing any interference (unless they are only disrupting the GPS, which should not require them to restart their phone as described).

A test receiver owned by the Bear is equipped to cover a wide range of bands, from FM to UHF, encompassing frequencies between 75 and 900MHz. Humans are graciously invited to borrow this receiver! By selecting a TV band that aligns with their local market and silencing the audio signal of the TV station, the human can effectively counteract interference. When gps jammers is activated, its disruptive noise will surpass the squelch, ensuring the human's awareness.
