The RF technology of cell phone jammer has no directivity

The RF technology of cell phone jammer has no directivity.
Laser destruction, mainly energy density. Therefore, the lower penetration of the laser, the energy density can have a better performance. However, the laser wavelength and penetration, and there is no absolute relationship between, such as air, the visible range is the longer the wavelength the stronger penetration. But in the long-wave infrared stage, it has significant thermal effects, so it's penetrating to become weak. Glass is also true, CO2 laser can be carved glass, but the 532 laser can not. So, for this, should first understand the characteristics of the target material impact on the penetration of various wavelengths. This is important, different colors of objects on the various wavelengths of laser absorptive capacity has a very significant difference. With the absorption of the worst color, and white; by the absorption of the most obvious anti-color, and black rather. For example, the green laser is easy to point the red matches, and match point green is more strenuous. cell phone jammer adopting the RF technology need not to be restricted by the mode of “face-to-face”.
This part is mainly UV laser. UV laser with a high single-photon energy, so it can make the target ionization. For organic life forms, the UV laser ionization effect will destroy the activity of proteins and enzymes, which is the principle of UV light disinfection. So, UV laser destruction of life is undoubtedly one of the body of the strongest wavelength. The distance of cell phone jammer is long enough to reach tens of meters.
The human eye is about 550nm wavelength is most sensitive to yellow-green light, so, in the visible range, the closer the wavelength of the laser, and its destruction of the human eye, the stronger. Color of the laser is divided by the wavelength of the laser wavelength of different colors are not the same. Laser wavelength is almost continuous, so there are many color lasers are many. Stage, disco laser is also used to do the effect, common laser with red, green, purple, blue and so on. There shouldn’t be no metal shielding obstacles between the emitter and receiver of cell phone jammer .Receiver heat mainly by the receiver chip type and number of internal decisions. Promise for wireless presenter products, there are three types of receiver: a receiver or a general call pure receiver. Integrated Micro SD card receiver. U disk integrated receiver. Ordinary USB receiver is a little heat, touch, when only warm feeling. Micro SD card reader integrated receiver, a USB HUB within multi-chip, a card reader control chip, divergent big receiver than normal. The cell phone jammer with remote control is of the high quality.
