GSM Modem Message Development While Long-Range Observing and Controlling

Hai Huang

Abstract

In order to realize the accurate and swift transmission of long-range data, we have adopted the way of steady and widely covered GSM SMS ,the MCU 89C52 can easily and effectively control the GSM Modem through Serial COM, MCU and GSM Modem using AT command to achieve control and data exchange. And we compared the different modes and the data format of SMS, chose the PDU mode with large data capability and widely use, realized long-range data transmission.
