Abstract: To improve the efficiency of products warehouse management and reduce goods loss and labor， we designed a wireless communication network for finding goods in the warehouse based on wireless communication module—NRF2401. This network included a label node for fixing a position on responding， and a coordinator for sending command to label node. The communication performance test showed that the node with a 0 dBm RF power and appending a PA with 20 dBm exhibited a lower packet loss rate less than 35% within a 150 m communication distance. And the electric currents were 011335 mA in a low\|power mode， and 470428 mA in an active mode， which means the lower energy consumption of communication， and also have a high reliability. Therefore， this browse network could be equipped in the whole process of warehouse management.
