In the framework of the hardware platform, CC2420 chip which supports IEEE 802.15.4 protocol is used as RF transceiver controlling chip. 32-bit high-performance ARM processor LPC2138 is used as both protocol controller and data acquisition. Through the OP to improve the transmitting power and receiving sensitivity. The system adapts to the Universal 2.4 GHz band and it has a high transfer rate and multi-channel features. Finally, the testing result shows that the transmitting power for the platform is more than 25 dBm, the communication distance is more than 3km. It realizes the communication between platforms.
