This work describes the different design and implementation of a GSM based remote systems. All existing systems either use GSM or GPRS technologies; however, GSM is the basic way of communication. Due to global GSM roaming facility and good network capability, there is virtually no requirement to build additional network. GSM based SMS services are very cheap and affordable; therefore transmission of data based on SMS in real-time applications has become very popular. GPRS data transmission speed is much faster than normal text message, approx 28 to 32 SMS per/min may be achieve over GPRS. This study explores different tools and technique being used to control communication network through SMS. We also critically review the merit and demerit of various existing solutions. The results of the study are reported in this paper.
