Cell phone jammer adopts the anti-explosive external die casting shell

WAPI is a Wireless LAN Authentication and Privacy Infrastructure (WLAN Authentication and Privacy Infrastructure) in abbreviation, is a security protocol, but also the mandatory standards in China's wireless LAN security. It is like infrared, Bluetooth, GPRS, CDMA1X other agreement, is a wireless transmission protocol, but with their different is that it is wireless LAN (WLAN) in one transport protocol only. It can be the same as free WIFI internet access, but it is more confidential than WIFI, while China's mandatory requirements of the relevant business institutions to implement the WAPI standard. WiFicell phone jammercomes in the palm size.
Therefore, as long as the country announced its support for mainstream cell phones WIFI Internet is bound to also support the WAPI wireless Internet access. Inches is the length of the unit. 1 inch = 2.539999918 centimeters (cm). Cell phone display size is usually measured by the length of the diagonal, in inches units, such as 3.6 inches, 2.8 inch. With the color of the increasingly popular cell phones, cell phone screen material is also more important. The species generally have TFT-LCD, TFD-LCD, UFB-LCD, STN-LCD, ASV, AMOLED and OLED several. STN, CSTN and DSTN present the main points, it is a passive matrix LCD devices, so the power consumption, energy saving, but a slower response time, 200 ms. cell phone jammer is durable.
In the traditional monochrome LCD display to add the color filters, and color of each pixel in the display matrix is divided into three pixels, respectively, through the color filter display of red, green, and blue, in order to display color the role of color to light green and orange for the main. TFT (Thin Film Transistor) that thin-film field-effect transistors, active matrix liquid crystal display is one. It can be "actively" on the screen to control each individual pixel, which can greatly improve response time. Generally faster TFT response time of about 80 ms, and the viewing angle, and can reach 130 degrees. cell phone jammer does well in blocking GPS signal.
TFT-LCD main components include: fluorescent tubes, light guide plate, polarizer, filter plate, the glass substrate, with the film, liquid crystal materials, thin-mode transistors, and so on. TFD (Thin Film Diode) screen, also known as thin-film diode transflective LCD display. TFD technology was developed by Seiko Epson Corporation and developed specifically with the cell phone's screen. It is a compromise between TFT and STN, STN than the brightness and color saturation, better power than TFT. Most important feature is whether the backlight is turned off (reflective mode) or turn on the backlight (transmissive mode) conditions, can provide high-quality, easy to watch the show, and has low power, high-quality, high response speed and so on. The right version ofcell phone jammersuitable for the location is needed.
UFB LCD is March 2002, Samsung released a cell phone with a new LCD display, with a thin, high-brightness features. UFB-LCD is specially designed for cell phones and PDA's screen, with a thin, high-brightness features. UFB LCD STN LCD contrast is twice the brightness TFT display with comparable, but less power than TFT display, and price and STN display similar can be said to combine these two are have the advantages of a product. ASV (Advanced Super View) technology is the SHARP LCD panel production technology in another breakthrough, this technology is mainly used in high-end market positioning SHARP LCD display. cell phone jammer is made of the high intensity material.
