Abstract: Based on AT91RM9200 microprocessor, the paper introduces the implementation process of one embedded wireless data terminal. This design can bring two advantages: the simplified hardware frame and the complete network protocols achieved by running ARM-Linux operating system on it. The two typical applications based on the device are presented and the key points of the design are analyzed in the paper.

Key words: wireless data terminal, ARM-Linux operating system, GPRS
