Wireless Jammer With WIFI 2.4G 5.8G and Bluetooth Signal Jammer
WLAN and Bluetooth are a kind of wireless technology, usually in the case of using the 2.4G frequency band, support data exchange within a short distance with fixed and mobile devices. From this perspective, WiFi or Bluetooth provide great convenience for people who need to use them to send information and files. For large companies, this makes WLAN cheaper because it can connect multiple systems with one connection. However, there are many problems in using WiFi and Bluetooth. In this state, WiFi jammers and Bluetooth jammers are needed to solve these problems.
The current WIFI signal jammers are all full frequency bands, which can shield all 2.4G and 5.8G WIFi signals. After the device was turned on, the mobile phone could not search its own WIFI signal soon, and it was impossible to connect and use it.
WiFi is actively used to track your location indoors, mostly through hotspot location triangulation in a manner similar to cell phone tower location triangulation. Bluetooth is also used for indoor tracking, particularly in Bluetooth beacon tracking technology. But WiFi blockes can protect your privacy and hide your location indoors.
The WIFI jammer is a special design to form an effective protection area. This jammer interrupts Wifi and Bluetooth. Wifi and Bluetooth Blocker transmits on two primary frequencies in order to block any Wifi or Bluetooth that is operating in the vicinity. Carry out your company presentations or meetings with security and peace of mind. When you switch on the device, you can be sure that no WiFi, Bluetooth or even wireless camera signals can interfere with your meeting within a radius of up to 20 meters. As soon as you switch the blocker off again, all radio signals are restored.
WiFi blocker prevents hackers from attacking
The most obvious aspect is that the privacy of your top secret documents is likely to be attacked by hackers because it is used as a wireless Internet, making it difficult for them to deal with hackers. On the other hand, both WiFi and Bluetooth can track your location and operating principles, which is similar to triangulating the location of a cellular tower. This makes it easy for others to see your location, which is not applicable to people's lives and work. In this case, WiFi blockers can play an important role in eliminating potential dangers.
People still pay more attention to security and privacy in work and daily life, and always hope to find a good way to prevent their privacy from being attacked or leaked. Therefore, please eliminate the potential danger that WLAN and Bluetooth may pose to you. This is very important. In order to meet these requirements, WiFi/Bluetooth signal jammer is the best choice, and users can choose the base according to the situation. In order to meet people's needs, WiFi/Bluetooth portable jammers and desktop WiFi/Bluetooth blockers have been invented, and people can choose a suitable WiFi/Bluetooth jammer.
What is a WIFI jammer? Is it legal?
A WIFI jammer transmits on the same frequency as the signal to be jeopardized. However, if the jammer sends its signal significantly stronger, it renders the original signal unusable - making communication more difficult or impossible.
In WLAN, this means that the exchange of data packets only works to a limited extent or not at all and the actual data stream can no longer be put together correctly. This can be a critical problem for devices that perform safety-related tasks.
however, Jammers are something completely normal in wireless technology. When the number of transmitters increased massively at the beginning of the 20th century, machines that were not well shielded caused interference to the radio signal. But even today, WLAN networks that transmit close together on the same radio channel sometimes interfere with one another. However, the problem is not so drastic that all data traffic comes to a standstill.
The possession of jammers is not generally prohibited. However, if at all, operation is only permitted by authorities and in special cases. This not only applies to WIFI jammers, but also to cell phone or Bluetooth blockers. Casinos and gambling halls have long struggled with the manipulation of slot machines with mobile phones. It would be a legitimate interest for the casino operators to use such a device - as long as no other communication outside the building is disturbed.
So many devices with as short a range as possible would have to be used so that the outside world is not influenced by the jammers. Of course, this drives up the costs.
WiFi jammer protects privacy
Nowadays, the demand for smart house systems is increasing. Devices connected to the Internet (called the Internet of Things) are everywhere. Therefore, in this case, all accompanying household items may become people's eyes and ears in your own home. In order to provide you with privacy protection, a portable or desktop WIFI blocker will solve your situation in advance.
The main WiFi frequency bands are: WiFi2.4G and WiFi5G, of which WiFi5G is further divided into WiFi5.1G and WiFi5.8G.
To make a WiFi jammer, you can determine the WiFi jammer of several frequency bands according to the WiFi frequency distribution on the site.
The shielding range of WiFi jammers in different frequency bands is also different. Under the same use environment and the same transmit power of the jammer module, the shielding range of WiFi2.4G is larger than that of WiFi5G. This is because the lower the frequency, the farther the wireless signal can travel, and the less the attenuation will be.
