Wireless Data Communication Based on nRF2401

This paper introduces the main characteristics, modes and configuration word of RF transceiver nRF2401 for the 2.4GHz ISM band .The hardware interface circuit between microchip AT89C52 and nRF2401 is designed,which solves the problem of level conversion and implement the bi-directional data transfers. The process of control under software and the result of debugging are also presented. This design for wireless data communication is reliable and stabile. It has a high data rate and can be applied in many wireless communication systems.
