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).

II. Working Principles

These communication modules transmit data between base stations and terminal devices via radio waves. Each generation of technology has improved in spectrum efficiency, data rates, and the number of connected devices:

· 2G Modules transmit data through narrowband FDMA (Frequency Division Multiple Access) and TDMA (Time Division Multiple Access) technologies.

· 3G Modules use WCDMA (Wideband Code Division Multiple Access) and HSPA (High-Speed Packet Access) technologies to achieve higher data rates.

· 4G Modules utilize OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) technologies, significantly enhancing data transmission capabilities.

· 5G Modules combine millimeter wave technology, ultra-dense networks, and edge computing to achieve higher spectrum efficiency and lower latency.

III. Features and Advantages

· 2G Modules: Offer extensive coverage and are ideal for voice communication and SMS services, providing a low-cost and reliable solution with mature technology.

· 3G Modules: Deliver higher data transmission rates, enabling effective mobile internet use and multimedia applications while supporting a larger number of user connections with increased network capacity.

· 4G Modules: Provide high-speed data transmission that supports HD video streaming and online gaming, and feature low latency for a superior user experience.

· 5G Modules: Achieve ultra-high-speed data transmission rates, facilitating 8K video streaming and virtual reality applications, with extremely low latency for real-time control and telemedicine, and support a vast number of IoT devices for smart city applications.

IV. Similarities and Differences

Similarities:

· All 2G, 3G, 4G, and 5G modules represent different stages in the evolution of mobile communication technology, each building upon the advancements of the previous generation.
