How does GSM work with Arduino?
The Arduino GSM shield allows an Arduino board to connect to the internet, send and receive SMS, and make voice calls using the GSM library. The shield will work with the Arduino Uno out of the box. The shield will work with the Mega, Mega ADK, Yun, and Leonardo boards with a minor modification.
How does a GPRS module work?
GPRS is a mobile communications standard that runs on 2G and 3G networks to enable moderately high-speed data transfers. General packet radio service (GPRS) is a mobile communications standard that operates on 2G and 3G cellular networks to enable moderately high-speed data transfers using packet-based technologies.
What is the purpose of GSM?
GSM stands for Global System for Mobile Communication. GSM is an open and digital cellular technology used for mobile communication. It uses 4 different frequency bands of 850 MHz, 900 MHz, 1800 MHz and 1900 MHz .
What are the 3 different types of GSM?
The GSM network is divided into three major systems: the switching system (SS), the base station system (BSS), and the operation and support system (OSS).
How do GSM modules communicate?
Connect RS-232 port of GSM module with the serial port of the computer. Insert a SIM card in the module. Open HyperTerminal from Start -> All Programs -> Accessories -> Communications -> HyperTerminal. Enter a name for the connection and press OK.
Can GSM work without a SIM card?
Mobile phones can work without a SIM card. Most phones come with functions that preclude the use of SIM cards. SIM cards are just enablers of key mobile network operations such as SMS, calling functions, and mobile data storage. Access to the internet, games, and some apps will work without a physical sim card.
