2G networks utilize digital transmission primarily to enhance the efficiency and quality of voice communication. Digital signals are more resistant to noise and interference compared to analog signals, allowing for clearer calls and improved security through encryption. Additionally, digital transmission enables features like SMS (text messaging) and better use of bandwidth, facilitating more simultaneous connections within the network. Overall, this technology marked a significant advancement in mobile communication, paving the way for subsequent generations.

synchronous serial transmission
2g network does not have bandwidth connection higher for video transmission..
2G was made in the year 1991.
Digital data transmission use voltage differences to directly represent the 1s and 0s that make up the data and are not modulated over a carrier.
Analog transmission came before digital ones
---2G Network--- The second generation (2G) network uses digital signal to transmit voice. Compared with analog signal, digital signal is more accurate, reliable, and scalable. As a digital network, the 2G network can carry text messages along with voice. Those text messages, known as SMS (Short Messaging Service), are hugely popular. In addition, a 2G mobile phone often integrates a data modem. It can connect to the internet by making modem calls to certain dial-up service numbers provided by the carrier. Through the internet, a 2G mobile phone can browse the internet via the WAP browser software built into the device.
Digital traffic channels - first g :purely analog 2g: systems are digital encryption: all 2g provide encryption to prevent eavesdropping error detection and correction: 2g traffic allows for detection and correction, giving clear voice reception channel access: 2g systems allow channels to be dynamically shared by a number of users
Analogue to digital is a conversion process not a transmission process.
2G, or second-generation mobile technology, refers to the digital cellular networks introduced in the 1990s. It offers data transmission speeds ranging from 9.6 kbps to 64 kbps, enabling basic services such as SMS (text messaging) and limited data services. While significantly slower than later generations, 2G laid the foundation for mobile communication by transitioning from analog to digital. Today, it is largely considered outdated, with most users relying on 3G, 4G, or 5G networks for faster speeds and more advanced services.
