Wi-Fi refers to a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for „wireless fidelity,“ however this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x. The Wi-Fi Alliance, the organization that owns the Wi-Fi (registered trademark) term specifically defines Wi-Fi as any „wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers‘ (IEEE) 802.11 standards.“ Although spectrum assignments and operational limitations are not consistent worldwide: most European countries allow for an additional two channels beyond those permitted in the US for the 2.4 GHz band (1–13 vs. 1–11), while Japan has one more on top of that (1–14), the 2.4G 2400-2450 MHz WIFI signal band is always the most widely used type. That is the reason why the WIFI 2.4G 2400-2450 MHz jammer is the most popular type among all WIFI jammer online sales.
Here, we’d like to recommend the WIFI jammer online sale offered by Jammerall. Jammerall has pushed out more than fifty newly developed WIFI jammers. The featured one is the 4W Powerful All WIFI Signal Jammer. Compared with other Wi-Fi signals jammer, this 4W Powerful All WIFI Signals Jammer for 2.4G and 5.8G enjoy more functions. It can not only blocking the frequency of 2.4G, but also blocking the frequency of 5.8G. In other words, the blocking device can cover all of Wi-Fi signals. Once it is turned on, it can create a “dead zone” that temporarily disables all WIFI signals within 25 meters. Equipped with four Omni-directional antennas, it can provide more effective jamming capability. To better meet the demands of worldwide customers, Jammerall also has several multi-functional WIFI jammers, for example the Powerful 8 Antenna Jammer for Mobile Phone/GPS/WIFI/VHF/UHF.

What’s the most important; it allows working 24 hours continuously with the desktop design. So as is a universal type that can be applied all around the world, we highly recommend it to all.
