http://www.alasartech-security.com/What is a cell phone signal jammer? A mobile phone signal jammer ;is a device that blocks reception between cell towers and mobile phones. Developed for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations. How do cell phone signal jammers work? Known as cell jammers, signal blockers, GPS jammers, or text stoppers, a cell phone signal jammer holds up the radio frequency in a given area, creating a sort of signal traffic jam that blocks all communication. Like a radio silence bubble, no calls or texts can be sent or received as long as the user is within range of the cell phone signal blocker. So, why are cell phone signal jammers used? Proponents of such technology argue that signal jammer devices are necessary for many places where humans just can’t seem to observe the widely accepted rules of proper cell phone etiquette. Think schools, theaters, vehicles, or an otherwise quiet train ride… pretty much any venue were talking, texting, streaming and the like might be deemed disruptive or even dangerous. Keep in mind, that a mobile signal jammer will not only block voice and text on your phone, it also interferes with GPS, WiFi, and probably most problematic of all — police radar. That’s why, as mentioned above, the Federal Government has banned the sale, promotion, and use of cell phone signal jammers in the US. So if you were envisioning a little peace and quiet, courtesy of a shiny new signal blocker, you might just have to settle for earplugs. RCIED JAMMER The RCIED jammer ;is based on the advanced technology of reactive jamming and is specially designed to defeat Remote Controlled Improvised Explosive Devices (RCIEDs). The RCIED jamming systems meet challenges from hostile conditions and are characterized by nonstop operating capabilities, rapid field installation, and disassembly. The innovative technology of reactive jamming guarantees the highest level of efficiency for radio signal detection and disruption in real-time in both urban and suburban areas. The wideband RCIED jammers are activated within milliseconds and assure 100% protection against radio-controlled improvised explosive devices. Nowadays different kinds of transmitters, radios, and even mobile phones can be used to remote control bombs and other explosives. All of them have different characteristics of channel size, modulation and output power. That’s why it is crucial that the jamming signal is created and adapted individually and covers each radio frequency waveform precisely. In other words, the design and software of the RCIED jamming systems should provide the ability to create jamming signals without any limit, which means that any modulations or adapted RF waveforms can be generated. The RCIED jammers have extended programming features, they are fast to set up and easy to use, have external batteries for autonomous operation, and can be easily transportable. The main advantage of the RCIED jammers is a programmable signal generation that assures precious adaption to the different adversarial signals. Drone Jammers: How They Work, Why They Exist and Are They Legal? It's not a secret that not everyone is ecstatic that there is a growing number of drones taking off to the skies nowadays. As with just about any piece of technology, there are drone pilots who use their drones less responsibly or more maliciously than others. With the growing concerns over privacy and security, it's not a surprise that there have been a lot of efforts to develop drone jammers. These anti-drone technologies have common goals – to bring down a rogue or prevent them from entering a restricted area. How are drone pilots supposed to feel about this relatively new development? Do we need to watch out for our neighbors taking down our drones with their own drone jammers? Are drone jammers necessary? Despite efforts by the FAA and the NTSB to regulate drone flight, it cannot be denied that they have been and continue to be used for purposes that are malicious, unethical, or downright illegal. Cases of drones being used for voyeurism are incredibly common, with a few well-documented cases highlighting just how disturbing drones can be in the wrong hands. They have also interfered with emergency response operations, caused delays in commercial flights, and used to smuggle contraband into correctional facilities. In 2015, a drone was able to fly onto the lawn of the White House – one of the strictest permanent “no-drone zones” in the country. This event proved just how drones can be when used to breach security, as they are too small to be detected by standard radar equipment. Although the pilot responsible for the drone was only flying for fun and claimed to have lost control of it, the incident opened the national consciousness to the dangers of drone use. After all, the lawn where the drone was recovered was the same lawn where the presidential helicopter lands. Without security measures, it would have been easy to mount an attack using the drone. With public safety and national security on the line, it really was only a matter of time before anti-drone technology was developed. Are they necessary? Arguably, yes, they are – at least, until a more comprehensive method for implementing accountability for drone pilots can be created. However, anti-drone technology must also be similarly regulated. How do drone jammers work? Short of shooting down a drone with physical projectiles, the only anti-drone technology in existence is what is commonly known as a “drone jammer.” As its name implies, such a device will jam the frequency – either 2.4 GHz or 5.8 GHz – that a drone uses to communicate with its ground station. The drone jammer does this by sending its own electromagnetic signal at the same frequency, thus overriding the drone’s communication systems. In most cases, this will result in the drone activating its Return to Home function, through which the drone pilot can be identified. This description may conjure images of a drone jammer that looks like a gun, but this may not necessarily be the case. True enough, there are handheld drone jammers in existence. However, these are heavy and bulky devices that take a lot of effort to deploy and can hardly be used stealthily. More commonly used are perimeter-based drone jamming technologies that use signal emitters placed around an area that needs to be protected from drone intrusion. Mobile phone jammer A mobile phone jam ;or blocker is a device that deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them. Jammers can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues. Because they disrupt the operations of legitimate mobile phone services, the use of such blocking devices is illegal in many jurisdictions, especially without a license. When operational, such devices also block access to emergency services. Remote Control Jammers And The Way They May Be Useful The remotes jamming devices are really nice tools and here we will try to explain to you a couple of things about them. The first thing here is the fact that the remote control jammer ;can be considered “friendly” unlike most of the other blocking devices. Unlike the other blocking devices such as cell phone signal zappers or GPS blockers, the remote control zappers can be used mostly for pranks and fun. This is why we don't understand why lots of countries have banned their usages like the usage of mobile phone zappers or even GPS scramblers. A really interesting fact about remote control signal zappers is the fact that they are actually fairly new to the market and now, even if you want to buy a new device, you will have to know that their prices are a bit higher. Anyway, if you want to buy such a device it will be better to know a couple of things about it. This is why would like to recommend you to read as much information as you can find on the internet about those devices because it is always better to know a couple of things about the technology you are about to own As we said in the beginning it is pretty important to know that you might have problems with the authorities owning one of those devices and this is why you need to check your local laws. Also, you should check the frequencies used in your country for remotes and the frequency of the remote that you want to jam. ; posted an update 1년, 5개월전
