History and Evolution of Mobile Technology

The journey of mobile technology began in the 1980s with the introduction of 1G analog phones. These early mobile devices were large, expensive, and could only make voice calls.

Over the years, mobile technology evolved rapidly:

• 2G brought text messaging (SMS) and better sound quality.

• 3G introduced internet browsing and multimedia.

• 4G enabled high-speed data, online gaming, and video streaming.

• 5G, the latest generation, offers lightning-fast connectivity, enabling smart cities and autonomous systems.

The upcoming 6G networks are expected to connect humans, devices, and AI systems in real time, creating a truly intelligent world.
