Difference Between 1G, 2G, 3G, 4G and 5G Technology

1G, 2G, 3G, 4G, and 5G are different generations of mobile communication technologies. Each generation represents significant advancements in terms of network capabilities and features.

Here are the key differences between 1G, 2G, 3G, 4G, and 5G technology:

1. 1G (First Generation):

• Introduced in the 1980s, 1G technology was the first commercially available mobile communication system.
• It used analog signals for voice transmission.
• Data transfer rates were very low, typically limited to 2.4 kbps.
• 1G systems had limited coverage and capacity and were primarily used for voice calls.

2. 2G (Second Generation):

• 2G technology emerged in the early 1990s, introducing digital cellular networks.
• It used digital signals and introduced various digital modulation techniques like GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access).
• 2G networks provided improved voice quality and offered additional services like text messaging (SMS).
• Data transfer rates increased to around 64 kbps, enabling basic internet access and email.
