Understanding 5G and 6G Technologies
What is 5G?
5G (fifth-generation wireless technology) is a significant leap from its predecessor, 4G LTE. It offers:
- Ultra-fast speeds (up to 10 Gbps)
- Low latency (as low as 1 millisecond)
- Higher device connectivity (can support over 1 million devices per square kilometer)
- Network slicing for customized usage
5G is already being deployed worldwide and is essential in IoT-enabled applications such as autonomous vehicles, industrial automation, and telemedicine.
What is 6G?
6G (sixth-generation wireless technology) is still in the early research phase, expected to roll out around 2030. It aims to improve upon 5G with:
- Terahertz (THz) frequencies for ultra-fast data transmission
- Near-zero latency (less than 0.1 ms)
- AI-driven networks for seamless automation
- Holographic communications and immersive experiences
- Massive IoT scalability with up to 100 times more connected devices
