The world is just getting comfortable with 5G, but the next leap forward — 6G technology — is already in development. Expected to launch commercially around 2030, 6G promises lightning-fast speeds, ultra-low latency, and AI-powered networks that will reshape everything from gaming and healthcare to smart cities and the Internet of Things (IoT).
In this in-depth guide, we’ll explore what 6G is, how it compares to 5G, key technologies, use cases, challenges, and how you can prepare for the future of 6G.
What Is 6G?
6G (sixth-generation wireless technology) is the successor to 5G and the next global wireless communication standard…
6G vs 5G: Key Differences
| Feature | 5G Today | 6G (Target) |
|---|---|---|
| Peak Speed | Up to 10 Gbps | 1 Tbps+ (1000 Gbps) |
| Latency | ~10 ms | Sub-millisecond |
| Spectrum | Sub-6 GHz & mmWave | mmWave + Terahertz |
Key 6G Technologies
