The wireless industry is already looking beyond 5G to the next major advancement: 6G. While 5G networks are still expanding globally, 6G is expected to revolutionize how we connect by offering ultra-high speeds, extremely low latency, and advanced use cases in AI, automation, and immersive experiences.
6G vs. 5G: Key Differences
| Feature | 5G | 6G (Projected) |
|---|---|---|
| Peak Data Rate | 10 Gbps | 100 Gbps – 1 Tbps |
| Latency | 1 ms | <0.1 ms |
| Frequency Band | Sub-6 GHz and mmWave (up to 100 GHz) | Terahertz band (100 GHz to 1 THz) |
| Expected Use Cases | IoT, AR/VR, smart cities | Holographic communication, digital twins, real-time AI |
| Deployment Timeline | 2020–2025 | 2030 and beyond |
What Is 6G Technology?
6G is the sixth generation of mobile wireless systems. It’s currently in the research phase, led by institutions like IEEE and companies like Qualcomm. Unlike 5G, which uses millimeter-wave (mmWave) frequencies, 6G is expected to utilize the terahertz (THz) spectrum to support data rates up to 1 Tbps and offer near-instantaneous response times.
Potential 6G Applications
- Holographic video calls and immersive meetings
- Brain-computer interfaces for medical and communication use
- Digital twins of real-world environments for simulation
- Real-time remote surgery and autonomous transportation
These applications require massive bandwidth and ultra-low latency—something only 6G can provide.
When Will 6G Launch?
According to the GSMA and other telecom research authorities, 6G is not expected to be commercially deployed until 2030. Early pilot programs and testing are underway in countries like South Korea, the U.S., China, and Japan.
Will 6G Replace 5G?
Like how 5G is still operating alongside 4G LTE, 6G will not immediately replace 5G. Instead, it will work in parallel to deliver high-performance capabilities for advanced use cases while 5G continues to serve mainstream mobile users and devices.
