GSM
GSM (Global System for Mobile Communications) is one of the most widely used mobile phone technologies worldwide. Think of it as the foundation that allows cell phones to make calls and send text messages. When you see GSM mentioned in a resume, it usually refers to experience with mobile network equipment, cellular towers, or mobile telecommunications systems. It's like the common language that mobile phones use to talk to cell towers. While newer technologies like 4G and 5G exist, GSM knowledge is still valuable because many systems still use it as a backup, especially in rural areas or developing countries.
