AbstractWith the rapid development of society, for wireless communications and data transmission demand is growing. In recent years, widespread IEEE 802.11 wireless local area network technology makes wireless networks more and more important, there are a growing number of related applications and products appear. However, most of the Wi-Fi technology for low power consumption and long-distance communication has a relatively high demand. ZigBee technology is a short-range, low-complexity, low-power, low-rate, low-cost two-way wireless communications technology. Mainly used for data transfer between the short distance, low power consumption and the transmission rate is not high, and various electronic devices typically have periodic data applications, data, and intermittent low latency data transmission.The project achieved a technology based on ZigBee wireless remote control car. Wireless module based on TI Texas Instruments CC2530 chip. It integrates a programmable flash memory with excellent performance RF transceiver and an industry-standard enhanced 8051 CPU, system, 8 KB RAM and many other powerful features. And it also has a sleep mode, the system makes it especially adapted to ultra-low
