【正文】 talled capacity has reached 150 million sets. Although there is also a short distance wireless Bluetooth technology, But in infrared munication technology low cost and broad patibility advantages, Infrared data munication in the future will still be a very long time inherent shortrange wireless data munications fields play an important role. The Improved Method Method one In various infrared transceiver products, although the transmission rate, transmission distance and other characteristics, But infrared transceiver products has been towards improving the transmission rate, increase the transmission distance and lower power consumption, expanding launch reception angle of development. In particular, as the technology development and maturity, the means of transmission is moving in the direction of pointtomultipoint. Therefore infrared remote control transceiver products have broader prospects for development. Infrared is actually a kind of electromagic wave. From the analysis of various natural ponent of the electromagic wave reflected spectrum is :ray, xray, ultraviolet, visible, infrared, microwave and radio wave. From the viewpoint of form, and they did not seem to, but if the wavelength in descending order, and we w ill find him all the only visible light spectrum of the entire μm so long little area, and adjacent to the visible light and infrared (including the far infrared, mid infrared and near infrared foreign) accounts for the spectrum of μm 1000μm of a major. Which micron wavelength range also includes UV, visible, near infrared, midinfrared and farinfrared, microwave. From the above analysis shows that infrared is a very rich spectrum resources, it currently has in production, life, military, medical, and other aspects have been widely used, such as infrared heating, medical infrared, infrared munication, infrared camera, infrared remote control, and so on. Infrared remote control is the many applications of infrared part of the current household appliances widely used in TV remote control, VCR remote control, VCD remote control, highfidelity audio remote control, are used infrared remote control, It allows the control of these appliances have bee very easy. Method two Infrared lies between visible light and microwave a wave, it is with certain clinical characteristics of the wave. In the nearinfrared, visible light and its adjacent, it is visible in certain characteristics, such as straightline transmission, reflection, refraction, scattering, diffraction, can be certain objects and can be absor
