Wi-fi is a kind of wireless signal we are currently the most used technology, in many mobile devices, access to the design of the wireless signal, let more products can be used to wifi, because wifi coverage gives people more convenient, wifi problems need urgent solution. Therefore, the wireless wifi jammer device is a necessary protection device.

Wifi technology as an important part of the wireless local area network (LAN) family, is developing rapidly in recent years, along with 3 g send a fast, more and more carriers are introduced (or consider a) allow the Wifi network to access the data for the PS domain business services, to alleviate the pressure of the cellular network data flow, under the new market environment, Wifi network and burst out of the application of new energy.For wifi technology, roaming, switching, security, interference and other aspects are the key points to be considered. With the increase of the capacity and transmission rate of the backbone transmission network, no matter the plane or the two-layer architecture will affect the user's broadband fast access; With the improvement of IAPP and Mobile IP technology, the development of Ipv6 can finally solve the problem of roaming and switching.Therefore, to interfere with the wifi signal, it is possible to make a wifi jammer blocker for the frequency band of wifi.

What is WiFi (wi-fi) IEEE 802.11 b wireless network standard of IEEE 802.11 specifications varieties, the highest bandwidth is 11 Mbps, under the condition of the signal is weak or interference, the bandwidth can be adjusted to 5.5 Mbps, 2 Mbps, and 1 Mbps of bandwidth automatically adjust, effectively guarantee the stability and reliability of the network. Its main characteristic is: speed, high reliability, in the open area, communication distance of up to 305 meters, in the closed area, communication distance of 76 meters to 76 meters, convenient with the existing wired Ethernet network integration, network costs are lower.The technology used to near 2.4 GHz frequency band, the band is currently no licensed wireless spectrum. There are two standards currently available: IEEE802.11a and ieee802.11b.

The advantage of wifi technology is that it covers a wide range of radio waves and has a very small range of radio coverage based on bluetooth technology. Secondly, although the wi-fi technology, wireless communication quality is not very good, data security performance less than bluetooth transmission quality also needs to be improved, but the transmission speed is very fast, can reach 11 MBPS, meeting the needs of individual and social informatization. Third, manufacturers enter the threshold of the field is relatively low. Manufacturers can set up "hot spots" in airports, stations, coffee shops, libraries and other places where they are more densely populated, and access the Internet via high-speed lines.

A new generation of wireless networks will create a new feel for wireless lans without the need for wiring and relative freedom. Demand determines the development of the market, which IT rarely seen technology or product to sample as IT has such a rapid growth momentum, not subject to any constraints, anytime, anywhere access to the Internet is no longer a dream, among them, the WiFi played a crucial role. A complete compatibility 802.11 standard IEEE802.11 b subset, it uses the open 2.4 GHz direct sequence spread spectrum, the maximum data transfer rate of 11 Mbps, also can be adjusted according to the signal strength the transfer rate of 5.5 Mbps, 2 Mbps and 1 Mbps of bandwidth. There is no need for linear transmission to reach the maximum 300 meters outside, and the maximum 100 meters in the case of indoor obstacles is the most used transmission protocol.
