In today's rapidly advancing technological era, mobile communication technology has become an indispensable part of our daily lives. From 2G to 5G, each generation of communication technology has brought significant changes to our lives. This article will provide a detailed introduction to 2G, 3G, 4G, and 5G modules, including their overview, working principles, features and advantages, applications, and the differences and similarities between them.
I. What are 2G/3G/4G/5G Modules?
2G Modules: 2G (Second Generation) mobile communication technology emerged in the 1990s, primarily based on GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access) technologies. It marked the beginning of digital voice communication and provided basic SMS (Short Message Service) capabilities.
3G Modules: 3G (Third Generation) mobile communication technology further enhanced data transmission capabilities, making mobile internet and multimedia applications possible. The main technologies include UMTS (Universal Mobile Telecommunications System) and CDMA2000.
4G Modules: 4G (Fourth Generation) mobile communication technology introduced LTE (Long-Term Evolution) technology, significantly increasing data transmission rates and network capacity, supporting high-definition video calls and high-bandwidth internet access.
5G Modules: 5G (Fifth Generation) mobile communication technology represents the pinnacle of current communication technologies, offering ultra-high-speed data transmission rates, extremely low latency, and massive device connectivity. The main technology is NR (New Radio).
