Why 2g use digital transmission?

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.
