Abstract
Wireless networking has developed rapidly in recent years. Currently, Wireless Personal Area Network （WPAN）becomes a new direction of development. Different from the past, high data rate transmission, extensive transmission distance isn’t the primary purpose anymore . In order to reduce the cost of installation and usage, such wireless network needed to be more efficient, more simple, and applied to shorter transmission. It also prompted the Institute of Electrical and Electronics Engineering （IEEE）began to promote a named IEEE 802.15.4 specifications standard, large-scale application in a factory process, home environment, health care and the monitoring sensor control system, such a low rate of small-range transmission of wireless specifications, We also call it low-rate wireless personal area networks referred to the LR-WPAN.
In this thesis, through IEEE 802.15.4, the advantage of saving electricity and the general idea about Zigbee, in the home environmental or working place, the structure has been built into the IEEE 802.15.4. According to the papers which presented the transmission mechanism of device and coordinator, with the appropriate hardware, using C programming language to built function and interruption. In order to achieve full-duplex voice transmission, and offer the references for the future applications, we expect that during the low-power and low-cost wireless network applications become mainstream, it can increase their additions and gives our lives more convenient.
