Wireless modems generate, transmit or decode data from a cellular network, in order to establish communication.Ī GSM/GPRS modem is a class of wireless modems, designed for communication over the GSM and GPRS network. It is an embedded piece of hardware.Ī GSM mobile, on the other hand, is a complete system in itself with embedded processors that are dedicated to providing an interface between the user and the mobile network. Difference between GSM/GPRS Modems, Modules, and MobilesĪ GSM module or GPRS modules are similar to modems, but there’s one difference: A GSM/GPRS Modem is external equipment, whereas the GSM/GPRS module is a module that can be integrated within the equipment.

These modules consist of a GSM module or GPRS modem powered by a power supply circuit and communication interfaces (like RS-232, USB 2.0, and others) for computers.Ī GSM modem can be a dedicated modem device with a serial, USB, or Bluetooth connection, or it can be a mobile phone that provides GSM modem capabilities.
What is GSM Module?Ī GSM module or a GPRS 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. It is now maintained by the 3rd Generation Partnership Project (3GPP). GPRS was originally standardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. General Packet Radio Service (GPRS) is a packet-oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM). It 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.
