What is 5G?

5G, the fifth generation of wireless technology, started commercial deployment around 2019-2020. It significantly improved upon 4G LTE by offering:

• Faster speeds (up to 10 Gbps theoretically)
• Lower latency (as low as 1 millisecond)
• Higher device capacity, supporting massive IoT deployments
• Improved reliability for mission-critical applications

5G supports applications like augmented reality (AR), virtual reality (VR), smart cities, autonomous vehicles, and ultra-fast mobile internet.

What is 6G?

6G is the sixth generation wireless technology currently in research and development, with projected commercial availability around 2030.

It promises to push connectivity boundaries even further by offering:

• Speeds up to 1 terabit per second (Tbps) — 100 times faster than 5G
• Latency as low as microseconds (even lower than 5G’s millisecond range)
• Advanced AI integration for network management and smart applications
• Improved energy efficiency and sustainability
• Support for holographic communication, advanced robotics, and truly immersive XR experiences

6G aims to create an intelligent, fully connected environment, where physical and digital realities seamlessly blend.
