It is based on lowcost close quarter wireless connections, in order to set up one to especially join with mobile munication environment fixedly, it is a kind of wireless datum and global norm of opening of pronunciation munication, its procedure is written in the microchip of one 9, Thus increase the munication alternative of the apparatus. The not joining working of technology apparatus of bluetooth, has offered and inserted the functions of works of the data, and have interface of ancillary equipment, can make up a little particular work. Should be used for looking from a present one, because bluetooth is small, the power is low, its application has not been confined to the peripheral hardware of the puter yet, can nearly be integrated in any digital device, especially those mobile device and portable apparatus not having high expectations for transfer rate of the data. 1 Technological characteristic of bluetooth Bluetooth technology is a technical specification of a kind of short distance wireless munication, its initial goal is to replace wired cable connection on various digital devices such as the existing palmtop puter, cellular telephone. The characteristic of bluetooth technology can be summed up for the following several points: 1) The global range is applicable: The working frequency band that the apparatus of bluetooth works is selected in 2 of the whole world GE. The ISM (. industry, science, medical science) frequency band of 4GHz, in this way users needn39。t be here through applying 2400 2500 Select the appropriate bluetooth radio transceiver frequency band for use in the range, its package is mainly chip and radio transceiver two parts, chip bottom enclose USB pass, transfer board to, used for, connect puter phone or other electronic products, after the chip receives the electronic signal, transform it into a radio signal, send the radio transceiver to send out [1 ]. It can cross the solid and nonmetal material to convey, its general connection range is from 110 meters, but through increasing the method to convey energy, its range can be expanded to 100 meters. 2) TDMA structure: The transfer rate of bluetooth technology is designed for 1Mbp s, carry on all duplexing munication by way of time, baseband its agreement whether circuit exchange and divide into groups association that exchange. One jump frequency send one divide into groups in step, each one takes a time slot to divide into groups frequently, can expand to 5 time slots too [2 ]. A asynchronous datum passway of technical support of bluetooth, or 3 plicated synchronous speech passways, or one conveys the passway of asynchronous datum and synchronous speech at the same time. Every speech passway supports the synchronous speech of 64 Kbps。 Asynchronous passway support most large speed 721 Kbps, reply speed 57 backward. The asymmetrical connection of 6Kbp s, or 432. Symmetrical connection of 6Kbps. 藍牙技術的研究與應用 15 3) Use and jump technology frequently: Bluetooth technology is adopted and jumped frequently( FH f requencyhapping) Expand spectral technology to solve the problem that interfered with.. Jump technology to divide frequency band into several jump channel frequently, in a connection frequently, the radio transceiver is jumping to another channel from a channel constantly according to certain yards of arrays, receive and dispatch both sides to carry on munication according to the law, other interference can not interfere with according to the same law only。 Jump instantaneous bandwidth frequently very narrow, through expand spectral technology make these narrow bandwidth succ
