The sixth generation of wireless technology, or 6G, was created to replace 5G. By using higher radio frequencies and combining edge computing and artificial intelligence (AI), it seeks to offer quicker speeds, lower latency, and more effective connectivity.

 

B. Key Features:

• Speeds up to 1 Tbps: 100 times faster than 5G, enabling near-instant data transfers.
• Sub-millisecond latency: Critical for real-time applications like autonomous vehicles and remote surgeries.
• Massive IoT support: Capable of connecting over 10 million devices per square kilometer.
• AI-driven optimization: Networks that adapt dynamically to demand and usage patterns.
• Terahertz (THz) frequencies: Unlocking vast bandwidth for unprecedented data rates.

C. Comparison with 5G

While 5G revolutionized IoT and low-latency applications, it faces limitations:

• Spectrum congestion: Crowded frequency bands reduce efficiency.
• Uneven coverage: Rural and remote areas often lack 5G access.

D. Historical Context

Wireless evolution has been remarkable:

• 1G (1980s): Analog voice calls.
• 2G (1990s): Digital text and basic data.
• 3G (2000s): Mobile internet and video calls.
• 4G (2010s): Broadband for streaming and apps.
• 5G (2020s): IoT, low latency, and edge computing.

6G builds on 5G’s millimeter-wave technology but introduces THz bands and AI to create smarter, faster, and more resilient networks.

Technological Foundation of 6G
