Dad Uses Signal Jammer to Stop His Kids from Going Online

 

The unintentional actions of a resident in Messanges, a town located in southwestern France, could result in a six-month imprisonment as he unknowingly interfered with telephony and mobile internet services in his vicinity using a signal jammers.

 

 

Remarkably, his motives were not malicious. He simply aimed to prevent his teenage children from using their mobile devices to access the internet after their bedtime.

 

 

A local mobile phone operator recently lodged a peculiar complaint with the French planning and radio frequency management agency (ANFR). The grievance pertained to the residents of Messanges, who experienced a complete halt in their cellular and mobile internet services during a specific time period each week, spanning from just before midnight until 3 AM.

 

 

In a recent development, the French planning and radio frequency management agency (ANFR) disclosed an unusual complaint filed by a local mobile phone operator. According to the complaint, the residents of Messanges experienced a disruption in their cellular and mobile internet services from just before midnight until 3 AM throughout the entire week.

 

 

The ANFR's investigation has revealed that radio frequencies in the area were being blocked by a mobile phone jammer, a device that is illegal in several European countries, including France.

 

 

During the early hours of the morning, around 1:30 am, a technician successfully traced the signal's origin to a dwelling located in the coastal town. The subsequent day, accompanied by law enforcement, investigators approached the man's residence and politely requested entry. Without hesitation, the individual readily confessed to employing a multi-band jammer.

 

 

As per the ANFR, the father of the family had installed a jamming wifi
 to prevent his teenagers from using their smartphones to connect to the internet instead of going to sleep. The motivation behind this decision was the children's addiction to social networks and other applications. After seeking guidance from internet forums, the father determined that a jammer would be the most effective solution to tackle his kids' excessive screen time.

 

 

Version 3: Alongside the request to deactivate the jammer and abstain from its utilization, the ANFR agent underscored the owner's responsibility to adhere to the regulatory framework, as per the agency's statement.

 

 

 

 

Experts strongly recommend that teenagers limit their daily screen time to a maximum of two hours. The excessive use of phones can have negative consequences on both their physical and mental well-being. Furthermore, excessive screen time has been associated with the development and progression of myopia, as well as conditions like dry eye syndrome, digital eyestrain, and discomfort caused by poor head and neck postures cell phone blocker.

 

In an effort to understand the constant smartphone usage among teenagers, Harvard researchers Emily Weinstein and Carrie James undertook a study. The outcome proved to be more intricate than anticipated, challenging the perceptions of many adults. Through an extensive survey involving over 3,500 American teens, they delved into the reasons behind sexting and the methods employed by adolescents to tackle online friendship dilemmas.Their research has truly amazed me. It is striking to observe that as adults, we tend to offer advice that is of no use and disregard teen phone use as a mere addiction. Consequently, parents are overlooking genuine opportunities to assist teenagers, as highlighted in their study wifi blocker.

 

 

Again and again from teens that they don't want to feel dysregulated when it comes to their technology use, and that they actually have pretty impressive, even amazing awareness of what tech habits they have that are serving them and the tech habits that they wish they could change. We had so many quotes from teens about just this feeling of, I don't know why, but this app, TikTok is running my life, or I keep falling asleep on social media and I wish I didn't. And what we found that's actually so powerful about that recognition is that adults often get really stuck in this position of being like a referee when it comes to teens technology use, where we're just blowing the whistle when kids do something wrong or calling teens out when they misstep. We get stuck in this position.

 

 

Want to Keep Your Teens (or Employees) from Texting Behind the Wheel?

 

It appears that an escalating number of people manipulate GPS apps while driving, resulting in their own set of distracted driving perils that are influenced by the app in use and the positioning of the device.

 

 

I like the texting-blocking angle myself, but I’m leery of the general data-blocking one. What about apps that use differential GPS? (Satellite plus base station data-path corrections, for greater precision.) What about streaming audio apps, like Audible or Spotify? (I use both on extended drives, and I’d hate to tell either a teen or employee she couldn’t, just to block texting). What if the driver wants to hand her smartphone off to someone else in the car to use for some data-related function, say looking up a restaurant or fiddling with the GPS or just checking email or text messages on behalf of the driver? (My wife did this for me for over a year whenever I drove, until she got her own smartphone.)

 

 

 

A cell phone jammer is an electronic device that blocks signal transmission between a cell phone and a cell tower. By using the same frequencies as cell phones, signal jammers can cause strong interference with communications between callers and receivers. Can effectively block signal transmission from networks such as UMTS, 3G, CDMA, GSM and PHS.

For any jammer circuit, there must be three important sub-circuits:

 

• RF amplifier


• Voltage Controlled Oscillator


• Tuning circuit

 

 

These 3 circuits combine to form an efficient cell phone jammer circuit.

 

 

Cell phone signal jammer working

 

 

1. Included in the RF amplifier circuit are transistor Q1, capacitors C4 and C5, and resistor R1. This circuit is designed to amplify the signal produced by the tuned circuit. The amplified signal is then directed to the antenna via capacitor C6, which effectively blocks any DC current and exclusively permits the transmission of the AC component of the signal.


2. As transistor Q1 is switched on, the tuned circuit connected to the collector is also switched on. This circuit, consisting of capacitor C1 and inductor L1, acts as a zero resistance oscillator, generating extremely high frequencies while experiencing minimal damping.


3. With the passage of time, the magnetic charge flowing through the inductor diminishes, leading to the capacitor being charged in an opposing or reverse polarity. This process is repeated, and eventually, the inductor charges the capacitor until it becomes completely discharged.


4. The process persists until internal resistance develops, resulting in the cessation of oscillation. The RF amplifier feed is transmitted to the collector terminal via capacitor C5, preceding C6. Capacitors C2 and C3 generate random pulses (noise) at the frequency produced by the tuned circuit.


5. By utilizing RF amplifiers, the frequencies produced by tuned circuits are boosted. The amplified output consists of the combined frequency generated by the tuned circuit and the noise signal produced by capacitors C2 and C3, which is then transmitted.

 

 

 

It is a reasonable thought for parents to contemplate buying cell phones for their children and teenagers. The underlying motive is to ensure that their children can always stay in touch with them. By having a phone, children have the ability to contact their parents at any given time, whether it is to arrange for a pick-up from school or to seek their parents' immediate presence in case of an emergency.

 

However, it is essential to be mindful of certain concerns that arise when buying a cell phone for your child. These concerns hold significant importance and should be recognized by numerous parents, as they involve not only the potential risks associated with cell phone use but also behavioral issues. Prior to granting your child a mobile phone, it is crucial to observe their behavior closely.

 

 

Addiction is problematic

 

The allure of cell phones and their technological features can easily ensnare children and teenagers, leading them down the path of addiction. Whether it's the constant texting, browsing social media, or engaging in endless conversations with friends, these activities can consume their every waking moment. Alarmingly, the prevalence of cell phone addiction is on the rise, compounding the issue further.

 

 

The detrimental impact of cell phone addiction is evident in the diminished attention paid to educational endeavors and other significant aspects of life. This is exemplified by students' continuous reliance on their phones to access social media platforms like Facebook or Twitter, engaging in conversations rather than devoting adequate time to studying and fulfilling course-related tasks.

 

 

Misconduct

 

The worst part about cell phones for kids is that many of them can engage in extremely inappropriate and potentially dangerous behaviors. Questions about bullying and how easily it spreads online have persisted for years. With mobile devices, people can easily be bullied. Children and teenagers can send each other angry messages non-stop. They may even make it harder for other children to enjoy their lives, or they may even ruin their own lives.

 

 

Additionally, children may send inappropriate images and text to others. They may send or receive dirty and possibly sexually explicit messages. They may not know how inappropriate these things are.

 

 

The pictures children take of themselves can also be quite disturbing. Children may take photos of themselves without clothes and send them to others. This can be harmful because children expose their bodies to others who want to see them. This is a serious threat and not many children realize what they may sometimes encounter.

 

 

How teens and parents can deal with screen time and device distractions

 

54% of U.S. teens say they spend too much time on their phones, and two-thirds of parents are concerned about their children’s screen time.

 

 

Parents are also concerned about the impact of screen time on their children, a separate survey showed. About two-thirds of parents said they were concerned about their children spending too much time in front of screens, and 57% reported setting screen time limits for their children in some way.

 

 

Meanwhile, some parents of teens admit they too struggle with the lure of screens: 36% say they themselves spend too much time on their phones. 51% of teens said they often or sometimes find their phones distracting them when trying to talk to their parents or caregivers.

 

 

With the rapid development of mobile communication technology and the popularization of smart devices such as smartphones and tablets, students’ use of smartphones has reached the level of one for every student. In the past two years, due to the epidemic, students’ use of smartphones has also increased. Come more and more. It is impossible to learn school class knowledge through online classes on mobile phones. Although the school has repeatedly banned students from bringing mobile phones to campus, some students still bring mobile phones to campus. Schools face many challenges in managing smartphones:

 

 

• Students use mobile phones to play games and chat online, and even adolescent children browse unhealthy content online, which seriously affects physical and mental health;


• Students do not sleep at night after school, cannot concentrate in class the next day, and easily fall asleep in class, etc., resulting in serious deterioration in academic performance;


• Use mobile phones and other devices to cheat in exams, etc.

 

 

Based on the current situation, what we can do is:

 

 

Parents should increase the time for interaction and communication with their children, pay more attention to their children's life and study, and take their children for outdoor sports. This will reduce the time children spend playing at home when they have nothing to do, and will also help cultivate parent-child relationships.

 

 

1. Guide children to play some educational games or learning software to make education interesting and emphasize that the Internet is a learning tool, not a toy.


2. Control the time children play games: Use a cell phone jammer to properly control the Wi-Fi network signal of the mobile phone so that students’ mobile phones cannot play online games within a certain period of time. Reduce conflicts between children and parents during the communication process.


3. Jamming mobile phones can be installed in school classrooms. Mobile phone wifi jammer can be turned on during class to block mobile phone signals in the classroom, and mobile phone signals can be restored during breaks.


4. The dormitory can be equipped with a mobile phone signal jammer. After turning off the lights at night, turn on the mobile phone signal jammer to restore the mobile phone signal late at night. Use cell phone signal jammer wisely.

 

 

 

It is crucial to consistently prioritize the protection of our privacy and the proper handling of our data, as well as the individuals who are granted access to it. This is a weighty issue that should not be trivialized.

 

The gravity of the situation intensifies when your insurance company is the entity that is gathering your data.A major issue with this is that, regardless of whether you are eligible for a discount through a GPS tracker or app installed in your vehicle, if you are involved in an accident, your insurance company will gather the collected data to assign fault to you and subsequently raise your insurance premium.

 

 

The data collected by these trackers includes a plethora of information, such as your acceleration rate, speed, braking speed, mileage, destinations, and location history. In the event that this data is misused, it can lead to grave consequences. Hence, resorting to a gps jammer would not be an ultimate solution.

 

 

 

There are several lesser-known yet intriguing facts about GPS jamming that many individuals are unaware of. It is our duty to elucidate on this matter, thereby safeguarding against the spread of misinformation.

 

You Only Need To Block GPS Signal To Jam a Tracker

 

 

This assertion is entirely unfounded. Many people firmly hold the belief that GPS trackers exclusively utilize GPS signals for tracking purposes. However, it is important to recognize that most NavSat systems and GPS tracking devices are also equipped with Sim cards. These Sim cards serve a dual function: enabling cell phone triangulation when GPS signals are unavailable and transmitting the gathered information to a monitoring station.

 

 

Contemporary tracking devices rely on a minimum of three satellite signals to accurately determine the position. Once turned on, these trackers are perpetually prepared to pinpoint the location, given that they are in an open area.

 

 

In order to obtain the live coordinates of the tracker, it is necessary to have a SIM card that is connected to a network operator within the tracker itself. The tracker utilizes cellular networks to transmit its location either through SMS text messages to a cell phone or by sending the location data to a server. This enables you to utilize an application, a fleet management system, or a web-based tracking platform to display the live location on a map.

 

 

Accordingly, it is critical to realize that a portable cell phone jammers is indispensable for disrupting GPS L1 signal, along with GSM, 3G, and 4G signals.

 

 

Criminals Use GPS Jamming Devices Too

 

 

It is common knowledge that GPS blockers are readily found and affordable on the internet. It is no wonder that criminals employ these devices to mask their identity and location during thefts.

 

 

When browsing online, you can come across GPS jammers that possess relatively low power but can still disrupt GPS signals over a wider range than just your vehicle. It is worth mentioning that these signal blocker are not limited to interfering with satellite navigation systems exclusively.

 

 

Even criminal organizations have recognized the value of these devices in facilitating their activities spanning tens of kilometers. Therefore, drug cartels or gangs might utilize them to interfere with navigation during deliveries, ensuring that their rivals remain unable to track their movements.

 

 

Criminal organizations have gone as far as using them to aid in the theft of expensive cars and valuable cargo transported by lorries. Consequently, if a GPS jammer were to be employed, the tracking functionality of an armored van or truck equipped with an anti-theft GPS device would be rendered ineffective in reporting its location when stolen or hijacked.

 

 

Employees Use a GPS Jammer To Avoid Being Tracked Via Fleet Management Systems

 

 

The primary drawback of GPS tracking devices stems from the general perception that they encroach upon personal privacy. This sentiment is particularly prevalent among commercial drivers who are resolute in preserving their own privacy rather than complying with their employers' insistence on maintaining control.

 

 

The implementation of vehicle tracking systems empowers fleet managers to effectively monitor their employees' performance, guaranteeing compliance with safety regulations and legal limits, facilitating efficient route planning, and ensuring a balanced work schedule. Nevertheless, it is crucial to strike a harmonious balance between protecting organizational interests and respecting employees' privacy.

 

 

To cover their tracks, certain truck drivers employ GPS jamming devices, while some employees misuse company-owned vehicles for personal errands. However, these individuals are unaware that using a Global Positioning System scrambler to jam a GPS tracker does not make the vehicle vanish; rather, it continues to appear on the live map as a trip that was not completed.

 

 

In addition, when you connect the jammer to a cigarette lighter socket while on a trip, a noticeable timeline will materialize, indicating the commencement of the jamming process, resembling a disrupted journey. Consequently, this may draw greater scrutiny from individuals who are monitoring your location.

 

 

 

Can someone block my security camera?

 

As a general rule, it is legally acceptable to obstruct a neighbor's security camera provided that you make adjustments exclusively on your own property without causing any damage to others' property. This can be accomplished by planting trees or erecting a sufficiently tall fence to impede the camera's field of vision. Another option is to install a security system to ensure the protection of your own property.

 

 

Why you should cover your camera?

 

These camera jammer can be exploited by cybercriminals, who can exploit their strategic positioning in your living room, kitchen, or office to violate your privacy and intercept sensitive discussions. Therefore, it is advisable to cover your webcam when it is not in use or adopt other precautionary measures to bolster your internet security.

 

 

Do you really have to cover your laptop camera?

 

It is a reasonable assertion that in order to ensure privacy and avoid unauthorized monitoring, particularly when unaware of it, the only viable solution to safeguard oneself from technological intrusion is to physically obstruct the hidden camera detector when it is not required. Furthermore, it is important to emphasize that this preventive measure poses no harm, as it merely entails using a piece of tape.

 

 

Can someone spy on you through your phone camera?

 

Few individuals stumble upon the fact, as it is deeply concealed within the license agreement. Through an extensive examination of over one million Android apps, the Pew Research Center uncovered that a significant number of these apps possess the capability to activate both the front and rear-facing signal blocker, enabling them to stream video from any location of their choosing.

 

 

Is there a device that disrupts cameras?

 

The use of camera jammers, also known as HERF Generators or Directional EMPs, allows for the disabling of security cameras. These handheld units emit microwave pulses that interfere with the characteristic signals employed in the microcircuitry of the cameras.

 

 

Is camera jamming illegal?

 

Under federal law, it is illegal to engage in the operation, marketing, or sale of any jamming equipment that causes interference with authorized radio communications, including cellular and Personal Communication Services (PCS), police radar, and Global Positioning Systems (GPS).

 

 

 

 

 

Many drivers dream of having a cellphone-free sanctuary within their vehicles. Nonetheless, the alleged creation of such a bubble by a Florida man during his daily commute did not necessarily result in a safer highway.

 

In Seffner, Florida, Jason R. Humphreys was found to have used a cellphone jammer in his Toyota Highlander sport-utility vehicle for as long as two years, as stated by the U.S. Federal Communications Commission. This unlawful activity took place during his daily commute, but he was eventually tracked down by both the FCC and the local sheriff.

 

 

According to Humphreys' statement to the FCC, he employed the jammer to deter people from talking on their cellphones while driving. It is important to note that in Florida, it is legal to talk on a cellphone while driving, even without a hands-free kit, although texting while driving is against the law.

 

 

Not only do signal blocker prevent consumers from making emergency calls, but they can disrupt critical communications by safety agencies, the FCC said. Hillsborough County sheriff's deputies confirmed that firsthand when they pulled Humphreys over. They said their two-way portable radios lost contact with the dispatcher as they got close to the SUV.

 

 

The FCC was alerted to a potential issue on a segment of Interstate 4, running between Seffner and downtown Tampa, by Metro PCS, the regional mobile operator currently owned by T-Mobile USA. On April 29, 2013, Metro PCS reported that their cell towers along this route were experiencing interference during the morning and evening rush hours. In response, the FCC initiated an investigation employing direction-finding techniques, which led to the discovery of strong wideband emissions originating from a blue Highlander.

 

 

Upon intercepting the SUV, FCC agents and sheriff's deputies initiated a conversation with Humphreys and subsequently carried out an extensive search of the vehicle. It was during this search that they uncovered the jammer, discreetly hidden behind a seat cover on the backseat, as officially stated by the FCC. Humphreys purportedly admitted to employing the vehicle cell phone jammer throughout his daily commute for a duration spanning from 16 to 24 months, according to the FCC. Further evaluation demonstrated that the device had the capacity to disrupt cellular signals across three separate frequency bands.

 

 

Humphreys is being charged with the unauthorized operation of a jammer, the use of an illegal device, and the intentional causing of interference.

 

 

 

 

 

Signal Jammer bars are meaningless

 

The signal bars on your cell phone are not a reliable indicator of the strength of the cell phone jammer interfering with your phone's reception.Although signal bars can give you an idea of your reception quality, it is crucial to understand that there is no standardized measure equating a specific number of bars to the strength of a signal jammer. Each cell phone manufacturer utilizes their own calculation approach.When positioned in close proximity, two dissimilar phone brands operating on the same cellular network may exhibit dissimilar quantities of signal bars.

 

 

It is commonly believed that the signal jammer is an excellent device. Nevertheless, is this perception accurate? Here, we present various approaches to gauge the potency of a cell phone Signal Jammer.

 

 

 

What’s considered “good” cell Signal Jammer?

 

RSRP (Reference Signal Jammer Received Power) is the metric used to gauge the strength of 4G and 5G cellular 5g jammer. Signal jammer strength is classified as excellent on the RSRP scale when it surpasses approximately −85 dBm, whereas anything below about −115 dBm indicates poor signal jammer strength.

 

 

Difficulties may arise in making phone calls, sending or receiving text messages, or utilizing internet data if the RSRP signal strength is less than −120 dBm.

 

 

Additionally, it is crucial to bear in mind the quality of your cellular connection, which pertains to the amount of usable signal you are able to receive in contrast to the interference or noise that may hinder the signal.

 

 

There are ways to measure cellular wifi jammer quality—see our Knowledge Base article for more about that—but the important thing to know is that you can have strong cellular Signal Jammer and still have slow data and dropped calls because your Signal Jammer quality is poor.

 

 

Your cell Signal Jammer will fluctuate

 

The main factor contributing to this phenomenon is the heavy user load on the cell tower. In order to accommodate all the connected devices, the tower antenna must distribute its power evenly. Consequently, the downlink transmit power is continuously adjusted. During peak usage times like rush hour or lunch hour, users may notice a decrease in power availability.The main factor contributing to this situation is the heavy user load on the cell tower. To ensure that all connected devices receive sufficient power, the tower antenna continuously adapts its downlink transmit power. Consequently, during peak usage times like rush hour or lunch hour, users may observe a significant reduction in power.

 

 

Should your cell gsm jammer exhibit a signal strength of −110 dBm RSRP, it is probable that you can place a call without experiencing any difficulties. However, if the signal strength of your −110 dBm Signal Jammer drops to −120 dBm RSRP due to tower congestion, there is a chance that your call may be disconnected momentarily. Nonetheless, you should be able to quickly redial and reconnect within a few seconds.

 

 

Physical barriers block cellular transmissions

 

Even if you are near a cell tower, it is possible to encounter a weak cell signal due to the presence of certain building materials. Materials like concrete, metal, low-e glass, wood, and plaster have the ability to reflect or absorb cellular frequencies, thereby impeding their transmission into the building and affecting the signal strength on your phone.The effectiveness of Cellular Signal Jammers can be compromised by different elements, including stucco with wire mesh, metal roofs, logs, and vapor barriers in attics. Moreover, if there is a substantial concrete building obstructing the path between you and the cell tower, it can also hinder the signal.

 

 

When you find yourself in outdoor settings, it is important to note that cell signal jammers can be impeded or obstructed by thick forests and hilly terrains. Moreover, signal problems may also arise in low-lying regions near lakes, rivers, and gullies, even if the jammer is positioned well above your current position.

 

 

The challenges faced in densely populated urban areas with skyscrapers are distinct. In certain instances, the uppermost floors of these buildings, reaching heights of forty or fifty stories, experience difficulties in accessing a stable cell signal due to the cell tower antennas being primarily directed towards lower elevations.

 

 

In these situations, a cell phone Signal Jammer booster for home, office, or vehicle can solve your reception problems.

 

 

 

Unbeknownst to many, GPS signals are an integral aspect of our daily routines. We rely on them ceaselessly to navigate and explore the vast expanse of our world.The applications of GPS in our daily lives are manifold and significant, encompassing the use of map apps on our smartphones, tracking our running distance with sports watches, and facilitating safe global travel. Although many willingly share their location for the sake of convenience and advantages, not everyone is equally enthusiastic about utilizing GPS.

 

What is a GPS Jammer?

 

To put it simply, a GPS jamming device is designed to interfere with GPS signals. These compact yet powerful transmitters work by emitting disruptive "noise" that conceals one's location and disrupts the functioning of a GPS device.

 

 

While GPS has become an integral part of our day-to-day activities, it is essential to delve into its functioning, especially when discussing jammers. The global positioning system, commonly referred to as GPS, relies on the reception of signals from satellite transmitters orbiting the Earth by trackers located on the planet's surface.When the GPS track receives signals from a minimum of four orbiting satellites, it utilizes a set of calculations to ascertain its position. Subsequently, the device transmits its location via a cellular network to a monitoring center, enabling the configuration of your real-time location.

 

 

GPS jammers operate by transmitting radio signals that share the identical frequency as a GPS device. This interference distorts the GPS satellite signals, overwhelming the GPS device and preventing it from accurately determining its position.

 

 

When in operation, GPS jammers interfere with a wide range of communication devices, including cell phones, internet networks, toll readers, and more. These jammers possess remarkable power, compactness, swift usability, low power requirements, and can be conveniently connected to a car's cigarette lighter. Additionally, they can be readily acquired through online sources.

 

 

What GPS Jammers Are Used For

 

Besides simply hiding one’s location, jamming devices are used for many reasons, including:

 

 

Eluding police detection in order to evade fines or tickets.

 

 

The act of blocking Wi-Fi connections.

 

 

Ensuring the secrecy of a vehicle or device's location is crucial in deterring theft and safeguarding against unauthorized access.

 

 

Restricting the capability of mobile phones and other devices to send or receive messages, calls, emails, and other notifications.

 

 

Taking steps to prevent the identification of devices.

 

 

Ensuring privacy of one's location from an employer while driving a vehicle provided by the company.

 

 

Initially created by the government for military and law enforcement use, GPS jammers have found controversial applications in various domains, raising doubts about their original purpose.

 

 

Ensuring the secrecy of vehicle and device locations is paramount in military operations, as it greatly influences the effectiveness of missions and the security of personnel. The utilization of GPS blockers in high-risk scenarios provides invaluable privacy and safety measures.

 

 

In non-military settings, the use of signal blockers and signal jammers is strictly prohibited in the United States, Canada, and several other countries. Despite the fact that GPS blockers are illegal, a significant number of individuals easily acquire them through online platforms and proceed to install them in their vehicles. However, it is important to be aware that those who employ such devices may be subjected to severe consequences, such as substantial fines, equipment seizure, and even imprisonment.

 

 

 

The proliferation of FPV drones has brought a flood of cheap wireless video tech. After flying and crashing a cheap FPV drone for a bit, [GreatScott] decided to try his hand at building his own video transmitter, which turned out to be a lot harder than expected.

 

 

While digital technology has caught up to the FPV world, a lot of systems still use analog video, especially for drone racing. The video quality isn’t great, but it has the advantage of very low latency. The technology is very similar to the old analog TV broadcasts, but mainly uses the 5.8 GHz license-free bands. It is essentially analog video signal, frequency modulated onto a 5.8 GHz carrier signal transmitted through an appropriately sized antenna.

 

After a brief failed experiment with a simple circuit built from discrete components, [GreatScott] turned his attention to voltage-controlled oscillators (VCO). He bought a couple of 5.8 GHz VCOs from Aliexpress, and created and used a simple opamp circuit to boost the FPV camera video signal to the required input level for the VCO. This failed to produce any identifiable image on his video receiver goggles. In an attempt to confirm that the VCOs produced the desired frequency, he ordered a similar 2.4 GHz VCOs and built a short range (20 cm) WiFi signal jammers. With a signal generator to create a simple input signal, and confirmed that it interfered with his laptop’s WiFi connection.

 

 

After more experimentation with other VCOs, the closest [GreatScott] came to success was a barely identifiable image transmitted using a Maxim 2.4 GHz VCO.

 

 

Building RF circuits that interfere with the legitimate signal around you, or broadcasting out of band, is generally not a great idea, and could earn you an unpleasant visit from the authorities.

 

 

One thing that has always peeved me off is when people are driving around staring at their phones. And then they get mad at me for smashing my horn when they almost hit me or someone else. Then they go right back to staring at their phone again… so i smash my horn again.

 

 

But the thought has crossed my mind more than once of being able to smash a button and silently disconnect their phones rather than having my life and property put in peril. Makes me smile, but I would get in more legal trouble than they would for smashing into someone with their vehicle “on accident” when in fact their neglect and inability to focus on operating a machine is the real fault. In my experience, i have been in several accidents due to neglectful drivers and others not following proper use of the road, they get no legal penalty and I end up having to pay the cost due to the fact that insurance is a scam that never pays out without a more expensive lawyer. But then again for those people who are responsible, jamming would likely have them pick up their phone to look at it when their hands free call or podcast or music stops, potentially causing more havock than a single irresponsible driver.

 

 

Only tangentially related, but makes me think about every time someone wrecked my car or almost wrecked my car anytime i read about frequency interuption/jamming.
