In this paper, the authors describe the different design and implementation of 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.
