As the economy improves day by day, cars are becoming more and more popular, and there are more and more gas stations providing fuel for cars, and wireless electronic jammers have appeared many times at gas stations.
Why use cell phone signal jammers in gas stations, oil depots and other places? Mobile phones are currently an indispensable daily communication tool in people's lives. After turning on the mobile phone in such a sensitive area, when the ringer rings, the internal components in the mobile phone will generate some energy, which will cause slight sparks. When the mobile phone is close to Fire may result when gas station is used. To avoid this problem, you can add cell phone jamming at gas stations, which can prevent some tragedies from happening. The security department has regulations prohibiting the use of mobile phones at gas stations. Therefore, in gas stations in important fire prevention areas, wireless signal jammers should not only be used in gas stations, but also best placed around gas stations.
According to media reports, oil companies recently issued a warning after three accidents caused by mobile phones igniting fuel mist during refueling. In the first case, the phone was placed on the gas tank cap of the car while the car was refueling, and the phone rang causing a fire that destroyed the car and the gasoline pump. In the second case, individual severe victims were disfigured, and their cars were fueled by oil mists caused by answering the phone while they were refueling. In a third case, individual victims also burned their thighs and buttocks because their phones in their pockets rang while fueling their cars, causing oil mist to burn. What you need to know: Mobile phones can ignite fuel or oil mist. When the phone lights up when plugged in, or when it rings, it releases enough energy to spark and burn. Don't use your phone at a gas station, or while refueling a lawn mower, boat, etc. The phone is not easy to use or must be switched off around flammable, explosive or dusty (eg soluble, chemicals, gasoline, grain dust, etc.) materials. The dangers posed by the use of cell phones at gas stations have now led to many concerns. Now gas stations in many regions have used camera blocker, and installing jammers is the most effective control method.
Mobile phone signals are almost everywhere, and all electrical devices are surrounded by mobile phone signals. It is necessary to install gps jammer for car. This ambient signal minimizes interference with other electrical equipment when the phone is not in use. This is because when the mobile phone is not in use, there will be no data exchange between the mobile phone and the base station, and a mutation signal cannot be formed. There is a relatively stable electromagnetic field around electrical equipment, that is, static electromagnetic field. The interference of this static electromagnetic field to electrical equipment is almost zero. When using a mobile phone, data is exchanged between the mobile phone and the base station, generating random transient signals that generate dynamic electromagnetic fields around electrical equipment. Dynamic electromagnetic field signals may cause sudden changes in interference signals, which may lead to failure of electrical equipment.
The company investigated the cause of 150 gas station fires. Its findings were surprising:
1) Most of the 150 cases were women.
2) Most of the fires are caused by people returning to the car when the oil nozzle is refueling, and pulling out the oil nozzle after refueling. The reason is static electricity.
3) Most people wear rubber shoes.
4) Most of the men waited until the car was refueled before going back into the car, which is why they didn't get caught in a fire.
5) Never use your cell phone when refueling your vehicle.
6) Contact with static electricity will ignite the volatilized oil mist in gasoline.
When installing wireless signal jammers in gas stations, it is best to set up some slogans prohibiting cell phone calls, and widely publicize safety common sense, so as to let more people understand and reduce the occurrence of accidents. Also keep in mind:
1) Turn off the engine.
2) No smoking.
3) Don't use the phone - leave the phone in the car or turn it off.
4) Do not return to the vehicle while refueling the vehicle.

cell phone jammer prevents GPS trackingBut what exactly can these surveillance drones do?
They can even identify if someone is armed at night, and they can track the person's location and send it to law enforcement.
The FAA is committed to addressing all privacy and personal data collection issues, and cellphone jammers prevent GPS location tracking.The U.S. Department of Justice explained that drones can only be used in the United States during war or large-scale terrorist attacks, and that all activities surrounding drone jammers are conducted in the United States.
But we can see that a decision has been made, but Rand Paul is still working to prevent the appointment of a new CIA director, who may support the US government-led strategy.The purpose of drones is to engage in battle on the battlefield.
It is a strike force in the war on terror.
As you know, U.S. senators recently blocked the CIA's new presidential election, most likely John Brennan, using a high-power GPS jammer to shoot down drones from the air.Kentucky Republican Rand Paul used the procedure to postpone the appointment.
The signal jammer is a very magical thing, after use, it will change very strangely when installed indoors.
So many people are puzzled, how can a small thing have so much energy, and some people even take the risk.In the room where the signal blocker is installed, using a mobile phone will find that there is no way to make calls, no way to answer, and no way to connect to the Internet, so naturally there is no way to receive information.
In addition, the test room signal jammer with Bluetooth function, then the Bluetooth function of the mobile phone cannot be used.
There are a large number of devices in our home that are connected to different networks.
There are network devices, storage devices and wireless network printers.
WIFI allows you to connect your home entertainment device to the Internet.wifi jammer is an important tool for shielding WiFi networks.Without a WIFI connection, you will rarely encounter electronic devices such as Blu-ray, DVD or TV players.

De plus en plus de téléphones portables sont introduits clandestinement en prison et l'obstruction entre l'extérieur de la prison a été brisée.
Das Schnüffeln und Stören von HF-Signalen in Kraftfahrzeugen signalisiert ein wachsendes Sicherheitsproblem，Dies hat zur Entstehung von Auto-Störsendern geführt.
Die meisten GPS Störsender können im Auto verwendet werden.
Zum einen können sie Angriffe abfangen, zum anderen wird verhindert, dass sie verfolgt und überwacht werden, und sie werden in der Automobilindustrie eingesetzt.Vor nicht allzu langer Zeit, als ich an einer technischen Konferenz in San Francisco teilnahm, wurde der High-End-BMW meines Kollegen von einem Cyberangreifer eingebrochen.
Von diesem Zeitpunkt an wurden Probleme mit der drahtlosen Sicherheit von Kraftfahrzeugen für mich zu einem echten Problem.Wie kam es zum Einbruch?
Mit einem 30-Dollar-Tool, das von Hackern entwickelt wurde, um die Sicherheitssysteme an Bord zu „pwn“, können ungelernte Kriminelle leicht High-End-Autos öffnen und stehlen.
Mit dem 30-Dollar-Tool aus China können Kriminelle einen leeren Autoschlüssel neu programmieren, mit dem diese Nicht-Technikdiebe innerhalb von zwei oder drei Minuten ein Fahrzeug stehlen können.
Imaginez vous dans le métro, dans le train, au restaurant, dans n’importe lequel de ces endroits publics où rien n’est plus désagréable que d’être dérangé par un inconscient qui raconte sa triste vie intime, donne des ordres ou éclate de rire sans même nous en faire partager la cause.Imaginez donc que dans un tel moment, la conversation soit brouilleur interrompue.
Le type, la nana regarde son mobile devenu muet en se demandant ce qui se passe, en n’y comprenant rien.
En jurant après cette cochonnerie qui ne marche pas.Et figurez vous que le responsable de cette interruption c’est vous… (ou votre voisin).Le principe est simple: le jammer envoie un signal assez puissant pour empêcher les mobiles adjacents de communiquer avec les antennes qui relient les appels.
Les petits couvrent quelques mètres (ils démarrent à 50 dollars), certaines entreprises en achètent des fixes (de 1.000 à 4.000 dollars ou plus) qui assurent la tranquillité dans un local, une salle, un immeuble.Parmi les utilisateurs on trouve un psy qui en a marre de se voir interrompu au milieu d’une séance de thérapie, un patron de restau qui ne supporte plus de voir les appels distraire ses employés sans arrêt et des profs, qui assurent ainsi que leur enseignement ne sera pas perturbé par l’extérieur.Les victimes collatérales (celles qui n’avaient rien fait de mal) peuvent être très nombreuses.Alors, qu’est-ce qui brouilleur telephone 4g est le plus insupportable, la personne qui ne sais pas se contenir en public et vous importune avec ses conneries ou celle qui se donne le droit de rétablir l’ordre toute seule, sans beaucoup plus de considération pour le droit des autres?Pour expliquer cette énigme, Todd Humphreys montre du doigt un boîtier d’aspect banal, posé dans un coin de l’atelier : “C’est un spoofer (“usurpateur”), un simulateur GPS.
Il capte les signaux authentiques des satellites GPS, puis les réémet sur la même longueur d’onde après avoir légèrement modifié les coordonnées.
Les systèmes GPS du voisinage vont capter en priorité le faux signal du spoofer, car il est plus puissant que celui d’un satellite situé à 20 000 kilomètres de la Terre.
