The range can be enlarged after adding the directional antenna for cell phone jammer

Infrared interface is the configuration of the new generation cell phone standard, which supports cell phones and computers and other digital equipment for data exchange. Infrared communication with low-cost, easy connection, easy to use and compact structure, so in small mobile devices to obtain a wide range of applications. Through the infrared interface, various types of mobile devices to exchange data freely. Infrared is a wavelength between 750nm to 1mm of the electromagnetic wave, its frequency is higher than microwaves but lower than visible light, is a person's eyes can not see the light. As the short infrared wavelengths, the diffraction barrier is poor, it is more suitable for applications requiring short-range wireless communication applications, data transmission for point to point line.  cell phone jammer also plays an important role in the institutional use.
Infrared Data Association (IRDA) will be used for infrared data communication wavelength range of 850nm to 900nm limited within. Cell phones equipped with infrared interface for wireless Internet access is very simple, no cable and PC CARD, as long as the agreement will be able to set up an infrared connection directly to the Internet. Infrared interface is now in the world is a widely used wireless technology, is a large number of hardware and software platform support; electrical pulses through the data and infrared light pulses to achieve conversion between the wireless data transceiver. Infrared interface features: point to point cable to replace. The new communication standard compatible with the earlier communication standards. Small angle (cone angle of 30 degrees or less), short-range, point-line data transmission, confidentiality. The more discount of  cell phone jammers the manufacturer can provide, the more orders the customer will sign.
Higher transmission rate, the current rate of 4M FIR technology has been widely used, 16M rate VFIR technology has been released. The main advantages of infrared technology: it can make cell phones and wireless transmission of data between computers; can be the same between devices with infrared interface for information exchange; while infrared interface, eliminating the need for downloads or other costs incurred in the exchange of information; docking due to the need to transmission of information, security, strong; infrared technology Disadvantages: short-distance communication, communication process can not be moved, the case of interrupted communication barriers; infrared communication technology, the main purpose is to replace the cable connection for wireless data transmission, single function, poor scalability. Infrared communication technology for low-cost, cross-platform, point to point high-speed data connection, especially embedded systems. The company is going to develop more new marketing channels of cell phone jammer .
The main application of infrared technology: devices connected, the information gateway. Equipment after completion of different devices connected within a file and information exchange. Information Gateway is responsible for connecting information terminals and the Internet. Infrared communication technology has been a number of worldwide support and the use of software and hardware vendors, currently the mainstream of software and hardware platforms offer support for it. Infrared technology has been widely used in mobile computing and mobile communications devices. Bluetooth is a short-range communications support equipment (usually within 10m) radio technology. Can include cell phones, PDA, wireless headsets, laptop computers, related peripherals and many other wireless information exchange between devices. Bluetooth standard is IEEE802.15, work in the 2.4GHz frequency band, bandwidth of 1Mb / s. The manager sends mobile phone jammer  to the customer as the gift.
"Bluetooth" (Bluetooth) was originally a unity in the 10th century Danish king, he was Sweden, Finland and Denmark unified. Using his name to name this new technology standard, the situation with the divided unity mean. Bluetooth technology uses high-speed frequency hopping (FH, Frequency Hopping) and Time Division Multiple Access (TDMA, Time DivesionMuli-access) and other advanced technology, the most inexpensive way to close several digital devices (mobile devices, fixed communications equipment, computer and terminal equipment, a variety of digital data systems, such as digital cameras, digital cameras, and even household appliances, automation equipment) reticular link. Bluetooth technology will be a variety of network peripherals unified interface bridge, which eliminates the connection between the device and replace them with a wireless connection. The technology improvement meeting of cell phone jammer is held in the second floor.
