Bluetooth high cost; RF technology susceptible to frequency interference; wall features protection for data security configuration issue; Bluetooth rather late, there is no clear, uniform standard, compatibility issues not yet resolved. Bluetooth is a short-range wireless data transmission, now frequently used mobile wireless data transmission in the infrared as well. Infrared interface is the standard configuration of a new generation of mobile phones, it supports the phone and computer and other digital equipment for data exchange. The worker is discussing the technical problem of  Cellular Phone Jammer with the process engineer.
Infrared communication has a low-cost, easy connection, easy to use and compact structure, so in small mobile devices access to a wide range of applications. Via infrared interface, various types of mobile devices can freely exchange data. Infrared is the wavelength of electromagnetic waves between 750nm to 1mm, which is higher than microwaves but lower than the frequency of visible light, is a human eye can not see the light. As the shorter infrared wavelengths, the diffraction barrier ability is poor, so more suitable for applications that require short-range wireless communications applications, for point to point data transmission line, transmission rates up to 16Mbps. Infrared Data Association (IRDA) data communication using the infrared wavelength range of 850nm to 900nm limited within. The process engineer has submitted the suggestion of the workers about the technical problems of  mobile phone jammer to Chief Engineer.
Phones equipped with infrared interface for wireless Internet access is very simple, no cable and PC CARD, as long as you can set up an infrared connection directly to the Internet protocol. Infrared and Bluetooth wireless data currently used as a transport protocol  cell phone jammer, then they have the technology different? Or what of these two technologies have their own advantages and disadvantages of it? Here we have to look through this table the differences between them. Because Bluetooth and infrared, the blue-red with their own advantages, many mobile phone manufacturers for integration into mobile phones, mobile phones currently on the market, the majority of Bluetooth-enabled mobile phones have infrared interface (individual machine type, except such as: MOTO V600); due to cost constraints, some of the mobile phone with infrared interface, and certainly does not support Bluetooth.
