The term "2G Standards" refers to the second generation of mobile telecommunications technology, which was introduced in the early 1990s. This generation marked a significant shift from analog to digital communication, allowing for improved voice quality, increased capacity, and enhanced security. Key 2G technologies include GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access), which enabled more efficient use of the radio spectrum. 2G standards also introduced features such as SMS (Short Message Service), allowing users to send text messages. This generation laid the groundwork for subsequent advancements in mobile technology, leading to the development of 3G and 4G networks, which further enhanced data transmission speeds and capabilities.
