GSM stands for Global System for Mobile Communications, which is a standard for digital cellular networks that is used globally. It is the most widely used mobile communications standard in the world, and is used by over 90% of mobile phone users.
GSM is a digital technology that uses time-division multiple access (TDMA) to allow multiple users to share the same frequency band. It uses a variety of signaling protocols and codecs to transmit voice and data over the air, and uses a system of cells and base stations to cover large geographic areas.
GSM is used for a variety of applications, including voice calls, text messaging, and data transfer. It is also used for machine-to-machine communication and Internet of Things (IoT) applications.
Some examples of GSM usage include:
Mobile phone calls: GSM is used to transmit voice calls between mobile phones and the network, allowing users to make and receive calls anywhere within a GSM coverage area.
Text messaging: GSM uses Short Message Service (SMS) to transmit text messages between mobile phones, allowing users to send and receive text messages regardless of location.
Data transfer: GSM uses General Packet Radio Service (GPRS) to transmit data over the air, allowing users to access the internet and other data services on their mobile devices.
Machine-to-machine communication: GSM is used in a variety of machine-to-machine (M2M) applications, such as remote monitoring and control of equipment and systems.
Internet of Things (IoT) applications: GSM is used in a variety of IoT applications, such as smart home devices and wearable technology, to enable connectivity and communication between devices
