What’s a WiFi jammer?

A WiFi blocker is just one of the many tools that people can use to cut off channels of communication. There are other types of “jammers,” such as radio and cell phone jammers, which help to stop communication over radios and cellular devices. WiFi jammer can help you stop your WiFi from being used by devices nearby.


There are many different models of WiFi blockers with different levels of strength and various features. Choosing the right model means understanding how WiFi blockers and their features work. You’ll also need to understand how WiFi works so that you can calibrate the tool correctly.

Jammers, including portable wifi jammer, have been used by military and law enforcement for years. They are great tools for cutting off communications that adversaries are using to speak amongst each other or gain access to resources. They can also be used to interfere with and defuse bombs, which has been a life-saving function many times over.

How to Block WiFi?

As with all jammers, wifi singal jammer work by projecting out the same radio waves as the devices that you are trying to jam. In the case of jamming WiFi, you’ll want to set your jamming device to the same frequency as your WiFi router.

Blocking WiFi can be tricky, though, because routers typically are set to automatically find the best channel of communication with devices. They are able to switch between frequencies to find the least crowded one, keeping your internet speed at a satisfying level. As a result, a WiFi blocker must be prepared to block more than one frequency, or you’ll need to know how to manually set your router. 

How to Buy a WiFi Jammer?

Because some WiFi routers have more advanced features, you'll want to review your router's settings before buying a jammer. Basic router models may only have one or two settings to choose from, while others may give you more control.

The basic rule is to buy a WiFi jammer that can interfere with the exact frequency your WiFi router uses to communicate with your device. To do this, you need to check exactly which channels your router is capable of, and then buy a jammer that can interfere with at least one of them.

1. The area used. The shielding range of the wifi signal jammer is based on the power of the jammer. If it is tested in the field, the shielding range is different according to the strength of the local environmental signal. For example, the weak shielding range of the indoor signal is large, and there are GSM jammer base stations for outdoor use accessories. Then the GSM signal is close to the outdoor shielding range!

2, the size of the power. As we all know, 2G, 3G, 4G and 5G: Before buying, you need to know which signals you want to block. Ordinary mobile phone signals (2345G) can be selectively blocked. If you only block 23G or only 34G, this It can be adjusted before leaving the factory, and there are 2.4GWIFI, 5.8GWIFI and other frequency bands. Generally, ordinary signals can be quickly shielded.

3, the frequency range. Shielded frequency bands: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900

Als im Februar 2019 der Privatjet von Kevin Wells auf dem Weg zum Hayward Executive Airport in der kalifornischen Bay Area den GPS-Empfang verlor, war das Signal gestört, und er holte sein Telefon heraus und begann, Bilder vom Armaturenbrett zu machen. Nach wenigen Sekunden sieht man die Signale von mehr als einem Dutzend frequenz störsender flackern, dann weiter sinken und schließlich sicher landen und langsam zurückkehren.


Wells filmte den Vorfall schnell, weil es nicht das erste Mal war, dass er auf GPS-Probleme stieß. Vor weniger als einem Monat erlitt seine Cessna an fast derselben Stelle einen ähnlichen Stromausfall. "An diesem Punkt ist es sehr klar, ich denke, es handelt sich um unbeabsichtigte oder beabsichtigte Interferenzen", sagte er gegenüber IEEE Spectroscopy. "Ich möchte es aufspüren."

Wells ist Opfer von störsender für handy geworden, bei denen bösartige oder bösartige Signale die schwachen Signale von umlaufenden Navigationssatelliten übertönen. Solche Vorfälle stehen in der Regel im Zusammenhang mit US-Militärtests, die zu gefährlichen Situationen und kurz vor dem Auftreten führen können. Eine kürzlich durchgeführte Spektrumsumfrage ergab, dass sie insbesondere im Westen der Vereinigten Staaten häufiger vorkommen, als wir bisher dachten.

Nach dem zweiten Vorfall kontaktierte Wells den lokalen Flugsicherungsturm, befragte andere Piloten und nahm sogar persönlich einen tragbaren GPS-Empfänger mit, um nach Störquellen in der Nähe von Hayward zu suchen, aber ohne Erfolg.

Glücklicherweise hat Wells andere Möglichkeiten, dieses Dilemma zu lösen. Als geschäftsführender Direktor des Institute of Theoretical Physics der Stanford University kennt Wells viele Forscher der Universität. Er nahm sein Video mit in das GPS-Labor der Stanford Engineering, wo Professor Todd Walter bereits GPS-Interferenzen untersuchte.

Walters Team arbeitet an einer Drohne, die autonom lokale Signale im GPS-Frequenzband ausspionieren kann, ohne für die eigene Navigation auf GPS angewiesen zu sein. "Aber wir haben keine Erlaubnis, die Drohne im Hayward-Luftraum zu fliegen, und wir sind noch nicht in der Lage, sie zu starten und die UAV drohne störsender zu finden", sagte Walter.

Im Gegenteil, Walter hatte eine andere Idee. Warum nicht Crowdsourcing-Lösungen für GPS-Empfänger in anderen Flugzeugen nutzen? Alle modernen Flugzeuge verfügen über ADS-B-Transponder – diese Geräte senden kontinuierlich ihre GPS-Position, Geschwindigkeit und Kurs, um die Flugsicherung zu unterstützen und potenzielle Kollisionen zu vermeiden. Diese ADS-B-Signale werden von nahegelegenen Flugzeugen und vielen Bodensensoren gesammelt, darunter ein offenes Empfängernetzwerk, das von der Schweizer Non-Profit-Organisation OpenSky organisiert wird.

Mit OpenSky-Daten besteht die erste Aufgabe der Forscher der Stanford University darin, Interferenzereignisse genau zu identifizieren. Sie fanden heraus, dass die meisten ADS-B-Empfänger Daten verlieren und nichts mit Mobilfunkstörungen zu tun haben. Einige Empfänger sind unzuverlässig, während andere durch Gebäude oder Bäume vom Flugzeug über Kopf blockiert werden.

Die Möglichkeit, den gps signal blocker von Wells mit Daten aus der OpenSky-Datenbank zu verknüpfen, ist ein wichtiger Schritt zur Charakterisierung echter Störungen. Die in den ADS-B-Datenstrom integrierten Integritäts- und Genauigkeitsindikatoren sind auch für Forscher hilfreich. "Ich denke, bestimmte Interferenzereignisse haben Eigenschaften, die wir jetzt erkennen können", sagte Walter. "Aber ich mache mir Sorgen, dass es andere Interferenzereignisse geben wird, für die wir kein Muster haben. Wir brauchen mehr Ressourcen und mehr Daten."

Walter hofft nun, seine Hayward-Forschung zu erweitern, indem er das eigene hochwertige ADS-B-Empfängernetzwerk der FAA nutzt, um mehr in den Daten versteckte Störsignale aufzudecken.

Die Verwendung des ADS-B-Signals ist für Forscher nicht die einzige Möglichkeit, GPS-Empfangsfehler zu beheben. Anfang dieses Monats veröffentlichten John Stader und Sanjeev Gunawardena vom U.S. Air Force Institute of Technology auf der PTTI 2021-Konferenz des Institute of Navigation ein Papier, in dem ein alternatives Störungserkennungssystem detailliert beschrieben wird.

Ein kleineres System wie dieses wurde rund um den Flughafen Madrid in Spanien in Betrieb genommen, wo 11 GPS-Empfänger ständig auf Störungen oder versehentliche GSM JAMMER überwachen. "Es ist teuer und die Installation dauert eine Weile", sagte Walter. "Ich denke, große Flughäfen wollen vielleicht tatsächlich so etwas, um ihren Luftraum zu schützen, aber für kleine Flughäfen wie Hayward ist das unmöglich."

Bis dahin müssen Piloten wie Kevin Wells beim Navigieren in GPS-empfindlichen Gebieten witzig bleiben. Die FAA gab schließlich eine Warnung an die Piloten heraus, die Hayward und den größten Teil der südlichen Bay Area abdeckten, und die Störung schien nachgelassen zu haben. Walter hat jedoch kürzlich die ADS-B-Daten 2020 in der Nähe von Hayward überprüft und festgestellt, dass 13 weitere Flüge möglicherweise stecken bleiben.

The FCC has just issued a special temporary authorization (PDF) to allow the DC Correction Department to test gsm jammer technology. This technology sounds like an excellent solution to a serious problem: prisoners across the country illegally use mobile phones in correctional facilities. In particular, the technology seems to be "directional", which means that unlike traditional jammers, traditional jammers can only block signals within a certain radius around the GSM jammer, while the technology seems to be able to stop some Signal of a room or building. . In fact, I am pretty sure that thousands of Americans want to see this technology used in movie theaters, theaters, and other performing arts venues across the country.

Desktop WiFi Cellular Phone Jammers Anti GPS Tracking Blocker

For a long time, prisoners secretly used mobile phones to plague Brazilian prisons. Now, signal jammer developed by Israel have helped. The price of the device in Brazil is about 520,000 reals, and its size is similar to a laptop with an antenna and GPS tracking system. When a prisoner is in prison, using a mobile phone, the mobile phone screen will display information such as the mobile phone number, service provider and SIM card content. Not only will it automatically interrupt the mobile phone call, but the law enforcement agency where the law is located will also lock the prisoner.

The multifunctional cell phone jammer introduced here is called "adjustable desktop mobile phone WiFi signal jammer with remote control". It is a desktop signal jammer that can adjust the output power by applying the output power. Therefore, each frequency band can be controlled individually or together. Therefore, in only one jammer, the functions of the mobile phone and GPS jammer are perfectly combined, because the shielded frequency bands are WiFi, CDMA, GSM, DCS, PCS and 4G, and only all TX frequencies cover the link. In addition, it is also designed with a remote control, which can help the operator turn the device on or off when he is not near the device.

In the United States, gadgets called cell phone signal jammer are becoming more and more popular, but the risk is also very small. Security experts say this is illegal and potentially dangerous.

San Diego (CBS 8)-Small tools called "phone jammers" are becoming more and more popular in the United States, but they also bring great risks. Security experts say this is illegal and potentially dangerous.

You can thank a man in Philadelphia who is tired of other cell phone passengers yelling on their phones in case of a sudden surge in the Internet caused by cell phone jammers. These devices can be purchased online at a price of between $40 and $1,000, which is the concern of some security experts.

Nowadays, even if you are an ordinary person living an ordinary life, almost everyone can suffer damage, such as being tracked and monitored by others. Therefore, there is very little privacy regarding their real-time location/activity. Therefore, it is time to take action and use gps signal jammer against these spies.

GPS jammers are devices specifically designed to prohibit the normal use of various GPS tracking devices. For this reason, many people can protect themselves without worrying about losing their secrets and privacy. It works like a mobile phone jammer, so it is very easy to use and install. Usually, it can be used in meeting rooms, recording rooms, banks, bidding rooms, meeting rooms, testing facilities, security departments, military departments, secret services, meeting rooms, courts, border police and drugs. Feel the need to stay safe, and whenever you are worried about your safety, you can ask for help from a GPS signal blocker. But where should you go?

But there are some restrictions because the locker room or business office is completely different from crowded public places. For example, if you use this Apple Camera Deactivator, it will definitely make a lot of people feel embarrassed, they just want to take photos or take pictures to remember their friends. The same applies to gsm jammer, but it may vary from place to place (for example, movie theaters absolutely must have such equipment in order to make the visitor’s experience uninterrupted and thus get a greater experience).

Current status of university classrooms

"Classroom should be about listening and paying attention." Even children know it, but today's universities are free, but mobile classrooms are a joke. For this reason, a university in a certain city was surprised to find that there was no signal from any communication equipment in the classroom. But two days later, the school voluntarily withdrew these gsm jammer devices, which seemed to indicate that this method was ineffective. How to clean up the classroom environment?

Phone Wifi signal jammer

Instant messaging, editing documents, downloading files and games...Electronic devices such as mobile phones and tablets can be used in different ways. She said: "After a while, I don't think it will decrease." "I think it will be less." This reflects the lives of people who struggle hard, a large part of which are still students educated on campus.

Coping Strategies of University Administrators-Mobile Phone Jammer

A student said on the Internet that her school, Tianjin University of Technology’s Central Institute of Information, has installed cell phone signal jammer in every classroom so that students can listen carefully. For every class that has become an island, visit teachers from time to time to teach them how to build corridors.

To this end, the reporter immediately contacted the school and said with gratitude that the school’s decision was to allow students to concentrate and listen. Regarding the management effect, a period of investigation and debate is needed.

Subsequently, the reporter also got a response from the school. Teacher Cui addressed this issue, saying that when the school installed the frequency jammer, there were still many problems to be investigated. "The school is consulting with the department to discuss the obstacles that may cause the problem. Therefore, these two days may only be an attempt to clean up the classroom environment and conduct school education management without reaching a conclusion. Cui admitted that although most students can understand the original intention of the school, some people still find it difficult to understand and the school can only temporarily return To the traditional way. Teacher class management.

"In today's situation of excessive media, the influence of the developed communication network is not limited to university classrooms. For example, meetings, the order of meetings of various social activities is affected by the clan. From the arc to the WeChat, Weibo messages are sent." Professor Wu said that teachers and students should reach a consensus in the classroom, that is, the level of education should not be undermined, and it is obvious that students play mobile phones in the classroom.

Professor Wu admitted that it is difficult to ensure the order of university courses is a common phenomenon, and there are currently no good management measures in universities. Although the school movement is managed in the short term, from the perspective of long-term development, schools should cultivate students' self-control ability, increase the cultural atmosphere of the campus, and improve the campus environment. Teaching Quality.

More and more people are increasingly concerned that their privacy would be leaked, and consciously protect their privacy. We all know that there are many ways and tools to silently steal our personal information, and even unknowingly.

We use different smart devices every day, such as GPS navigators, laptops, smartphones and so on. These devices give us a lot of convenience, but there is no doubt that your personal information is also leaked from these devices. You can say that your wireless gadget is the double agent of the stolen person.

We use Wi-Fi connection, but we do not know that it can be easily hacked. We use Bluetooth, we have never heard of Bluetooth hacker technology. When we use GPS to determine where we are and how we get where we need, we find there may be gps tracking.

From these aspects, it is not difficult to understand why these gsm jammers are so popular in the world . This is because people want to protect their privacy.

But why jammers are illegal in many countries, because their use may affect other agencies, such as gps jammers may disrupt others' gps navigation. So when we use jammers to protect our privacy, we should not forget the rights of others. The jammer should be used appropriately.

This is the advice we give for you to use jammers appropriately:

Do not use jamming devices in public places. We recommend that you use blockers in a private location. Try not to open it in public places, because you may violate the rights of others. You are free to use jammers in your car or at home. Also, choose a signal blocker with the proper working range you need to avoid interfering with someone else.

We have the right to defend our privacy, but we should not violate others' right. You should remember that other people want to communicate freely. Try not to block them. Because there may be an urgent call.

Find the frequency you need to interfere with and select jammers with appropriate working range. Here you can find what you want.

More signal jammers can be found in jammer-buy.com. The most affordable price, high quality, one year warranty.


The benefits of using a mobile phone are hard to overestimate. These gadgets give us the opportunity to communicate with every part of the world. You know that you can not always be close to your family or friends, but through mobile communication, you will be close to them, and how much you really are.

Recent statistics on the use of mobile phones when driving claims for more than 20% of deadly car accidents are due to improper use of mobile phones. Hundreds of people around the world every day because of the use of mobile phones and injured around the world. The cool thing is the same technique to kill, which makes things right. I'm talking about gsm jammers.

According to some experts, the new mobile phone jammers will reduce the number of car accidents. If you are still many people still want to know how to do this, let's take a brief look at this topic, saying that many of us are talking on the phone while driving. This is why scientists have designed a special type of mobile jammers that should be installed in some of the latest models of cars.

Of course, this thing has a lot of negative side, but before doing so, we pay special attention to this career. The first thing we should be aware of is that it will certainly reduce the number of car accidents. In the car rather than talking on the phone, we need to pay attention to the road, we only pay attention to it. This has been proved by experts. But if we talk on the phone, we can not be as focused as the road, often accidents. Our braking and maneuvering responses are 45% slower. That's why more and more people are trying to protect their children with jamming devices on the car. There is also a positive thing is that if you are a jib-jabber while you spend a lot of time in the car, if your signal is blocked, you will lower your monthly bills.

What is the disadvantage of using a cell phone jammer in a car? First of all, knowing that sometimes you may want to make an emergency call is very important. If this happens and the signal inside the car is stuck, it means that you have to stop and call. It is very uncomfortable, especially when you remember the fact that the outside may rain, or you may hurry to make important meetings. But from the other side to see this. If you do not call, you will not be dangerous to other drivers, which is safer for you.

I hope that after reading this article, you will consider three times before you can use your phone in your car. But if it is almost impossible to control how to do, you sure the call will still distract If you do not want your smartphone to steal your attention or distract your relatives - install a small portable phone signal jammer on your car and keep 100% on the road.


Many people may be in doubt that is there any danger on cell phone jammer to our health Because they play a variety of frequencies, and are these frequencies dangerous for us? Now more and more people are buying mobile phone placement machines and any other blocking devices. From this point of view, in fact, already know the answer, because the masses of the eyes are discerning. We can fully understand them because we know how important it is to protect your privacy, and because most governments are doing their best to spy on everyone, we have no choice but to buy these jammers and try to protect our privacy.

But we have to technically illustrate this point. On health issues, cell phone jammer has passed all the safety and health tests, thanks to this fact, you can rest assured to buy and use. If you remember, the same health problems were worrisome when the phone was first introduced into society. But after testing, the result is the same - no harm.

Also, from the working principle of the jammer, you should remember that the gsm jammers are transmitting the same frequency band as the phone to interfere with the normal work of the phone, that is, the jammers for us are similar to the phone for us. And today, are there any equipments we stay with together longerthan the phone itself ? What kind of equipment is more popular than mobile phones? So, if we are talking about the harm of mobile jammers - they are the same as the phone itself. With Wi-Fi signal blocking the same thing, are they just as a Wi-Fi hotspot, are these hot spots dangerous? Another point you should know that radio signals and light, sound waves and gravity follow the same inverse law, that is, the distance is doubled, the energy is reduced to a quarter. In other words, the signal strength is attenuated with increasing distance. The most interesting fact is that people are concerned that GPS / GLONASS interference devices are harmful, but they do not even know that they are surrounded by the signals of these positioning systems every day.

Then we would like to remind you again here that it is very important to know what type of frequency you want to play. You can find any type of information about the phone blocker and other blocking devices on the Internet and on special websites. One thing is for sure - this technology will not stop developing.
