Bluetooth和WiFi的认证简介
• In this rapid developing communication times, wireless communication technology gets more and more, wider and wider application for its low cost, fast construction period and convenient use. And going with the improvement in technology, wireless communication has gently achieved the transmission speed to compare beauty with traditional fixed communication. • There are many techniques to actualize wireless linking. In different application regions, what technology they need have different complexity. For example, if we just want to perform a remote control for a lamp, a wireless command with power on/off code is enough. We needn’t consider about the transmitting speed even about dependability ---- if failure transfers, do it once again. In contrary with it, some domains, such as telegraphy and telemetry, need a complex construction system to deal with transmitting rate, frequency confliction, internet linking and etc. Bluetooth, Wi-Fi, Wi- Max, HomeRF, ZigBee are representatives for the latter (with complex protocol system). • Among the present civil domain, Bluetooth and Wi-Fi take the main parts. Here we mainly discuss about them two.
