Title: Find information about GSM Module.
In this week, we just only find information about GSM Module. Based on the information, GSM is mean Global System for Mobile Communications. GSM is a standard developed by the European Telecommunications Standards Institute (ETSI).
A GSM Module was created to describe the protocols for second-generation (2G) digital cellular networks used by mobile phones and is now the default global standard for mobile communications – with over 90% market share, operating in over 219 countries and territories. Its is mean, a GSM Module just only use in receive and transmit message and call.
A GSM module is a chip or circuit that will be used to establish communication between a mobile device or a computing machine and a GSM or GPRS system. The modem (modulator-demodulator) is a critical part here.
A GSM Module just only can be control by using AT commands. AT is the abbreviation for Attention. These commands come from Hayes commands that were used by the Hayes smart modems. The Hayes commands started with AT to indicate the attention from the MODEM. The dial up and wireless MODEMs (devices that involve machine to machine communication) need AT commands to interact with a computer. These include the Hayes command set as a subset, along with other extended AT commands.
This is example of GSM Module that we can get at the market.
