What is a WiFi Jammer?
A WiFi jammer is an electronic device used to jam or block WiFi wireless network signals. It is a device similar to a mobile phone jammer, which can interfere or conflict with the target WiFi signal by emitting electromagnetic interference signals of a specific frequency, so that the target device cannot connect to the WiFi network normally.
WiFi jammers are usually used in some special occasions, such as in some public places, exams, business negotiations, political meetings, sensitive affairs, etc. In order to protect personal privacy and confidentiality, it may be necessary to use Wi-Fi jammers to block WiFi signal to avoid being tapped, monitored or recorded.
Wireless Jammer - 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.
Which frequency bands does the WiFi jammer block?
WiFi jammers are usually designed to shield 2.4GHz and 5GHz wireless signal frequency bands, which are the frequency bands used by most Wi-Fi devices at present. These frequency bands belong to IEEE 802.11b/g/n and IEEE 802.11a/n/ac standards respectively.
The 2.4GHz frequency band includes 14 channels, and each channel interferes with each other. Therefore, WiFi jammers usually block the entire 2.4GHz band to ensure complete shielding.
The 5GHz frequency band includes multiple channels, and each channel is independent of each other. The WiFi jammer can choose to block specific 5GHz channels, or you can choose to block the entire 5GHz band.
Why use a WiFi blocker?
WiFi jammers are often used to protect personal privacy or confidentiality, or to prevent inappropriate network usage. Here are some situations where a WiFi blocker is used:
Protect privacy: In some public places, such as cafes, libraries, airports, etc., in order to prevent others from eavesdropping or monitoring your network activities, you may need to use a Wi-Fi blocker to block wireless network signals.
Prevent cheating: In exams or competitions, in order to prevent candidates or contestants from using mobile phones or other wireless devices to cheat, you may need to use a WiFi blocker to block wireless network signals.
Confidentiality: In business negotiations, political meetings, sensitive affairs, etc., in order to protect the confidential information of individuals or organizations, you may need to use a WiFi blocker to block wireless network signals.
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.
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.
