1. What is 5G Technology?
5G, or the fifth generation of mobile networks, builds on its predecessors (1G to 4G) by offering faster speeds, lower latency, and greater connectivity. Introduced in the late 2010s, 5G uses higher-frequency bands (millimeter waves) and technologies like beamforming and massive MIMO (Multiple Input Multiple Output) to deliver up to 10 Gbps speeds.
Key benefits of 5G:
- Up to 100x faster than 4G
- Latency as low as 1 millisecond
- Connects up to 1 million devices per square kilometer
- Enables IoT, smart cities, autonomous vehicles, and remote surgeries
2. What is 6G Technology?
6G is the sixth generation of wireless communication technology, currently in the research and development phase. It aims to push the boundaries of 5G by offering even faster data rates, sub-millisecond latency, and new communication paradigms like holographic transmission and brain-computer interfaces.
Projected capabilities of 6G:
- Speeds up to 1 Tbps (terabit per second)
- Latency under 0.1 milliseconds
- Full-spectrum AI integration
- Terahertz frequency bands (100 GHz – 10 THz)
- Support for extended reality (XR), tactile internet, and space-air-ground-sea networks
3. Key Differences Between 5G and 6G
| Feature | 5G | 6G |
