GSM and GPRS modules are chips or circuits that are used to establish communication between a computing machine or mobile device and a GSM (Global System for Mobile communications) or GPRS (General Packet Radio Services) system. They do this by enabling communication between a microcontroller or microprocessor and the GSM/GPRS network.
How do GSM and GPRS modules work?
GSM and GPRS modules are like GSM and GPRS modems except for one crucial difference: Modems are external devices whereas modules can be integrated or embedded into a piece of equipment. GSM and GPRS modules are therefore known as embedded hardware.
A GSM and GPRS modem consists of a GSM and GPRS module assembled together with other components such as a power supply circuit, indicators and communication interfaces such as a USB 2.0 or RS-232. The communication interface helps to connect the module on the modem with a microcontroller or external computer.
What are GSM and GPRS modules used for?
GSM and GPRS modules allow microcontrollers to communicate wirelessly with other instruments and devices. Such wireless connectivity opens up to a wide range of applications including:
