Global System for Mobile Communications (GSM)
The GSM (Global System for Mobile Communications) is a widely used digital cellular network technology that enables mobile communication and data transmission. It has played a crucial role in the development of mobile phones and other ICT (Information and Communication Technology) gadgets. Here are some ICT gadgets that utilize GSM technology:

1. Mobile Phones: GSM is the most common cellular network technology used in mobile phones worldwide. GSM-enabled phones allow users to make voice calls, send text messages, and access mobile data services like internet browsing, email, and social media.
2. Tablets: Many tablets on the market come with GSM capabilities, allowing users to make calls, send texts, and use mobile data connections. These tablets are essentially larger versions of mobile phones, offering a broader screen for browsing, gaming, and multimedia consumption.
3. Smartwatches: GSM-enabled smartwatches are becoming increasingly popular. These watches can connect to cellular networks independently, allowing users to make and receive calls, send messages, and access mobile data without needing to be paired with a smartphone.
4. Vehicle Tracking Systems: GSM-based vehicle tracking systems utilize GPS (Global Positioning System) and cellular connectivity to track the real-time location of vehicles. These systems are widely used in fleet management, logistics, and vehicle security applications.
5. Smart Home Security Systems: Some home security systems employ GSM technology for communication purposes. These systems use cellular networks to send alerts, notifications, and live video feeds to homeowners’ mobile devices, ensuring remote access and monitoring of their homes.
6. IoT (Internet of Things) Devices: Many IoT devices, such as smart meters, environmental sensors, and industrial monitoring systems, leverage GSM technology for connectivity. GSM enables these devices to communicate wirelessly, transmit data to servers, and enable remote control and monitoring.
7. POS (Point of Sale) Terminals: GSM-enabled POS terminals are widely used in retail and hospitality industries. These devices allow businesses to accept mobile payments, process credit card transactions, and print receipts using a cellular connection.
It’s important to note that with the advancement of technology, other cellular networks technologies like 4G LTE and 5G are gradually replacing GSM in many areas. However, GSM remains prevalent in various parts of the world, and its legacy continues to influence the development of ICT gadgets.
The GSM (Global System for Mobile Communications) is a second-generation digital mobile telephone standard using a variation of Time Division Multiple Access (TDMA). It is a mobile telephone using wireless technology that allows users to communicate with people that are not within their reach.
It is the most widely used of the three digital wireless telephone technologies – CDMA (Code Division Multiple Access), GSM, and TDMA.
It operates at either the 900, 1800, or 1,900MHz frequency bands.
The GSM network can be divided into three broad parts
(a) The subscriber carries the mobile station
(b) The base station subsystem controls the radio link with the mobile station
(c) The network subsystem performs the switching of calls between the mobile users and other mobile and fixed network users
