What is the difference between GSM, UMTS and LTE? – Commsbrief
GSM, UMTS and LTE are cellular technologies that enable second (2G), third (3G) and fourth (4G) generations of mobile networks. GSM uses FDMA & TDMA, UMTS uses WCDMA and LTE uses OFDMA & SC-FDMA for air interface. The bandwidth is 200 kHz in GSM, 5 MHz in UMTS and 1.4 to 20 MHz in LTE.

GSM (Global System for Mobile Communications) is the technology that lets devices connect to the mobile network for calls, SMS, and data. In Arduino and embedded projects, a GSM module acts like a “cellphone for your circuit,” allowing your system to send alerts, receive commands, track locations, and communicate remotely without Wi-Fi. This makes GSM perfect for remote monitoring, security systems, automation, and field deployments where long-distance, reliable communication is needed. #Hajimer
