Introduction of Wireless Communication

Wireless communication technology हर दशक में एक नई क्रांति लेकर आती है। 1G से लेकर 5G तक का सफर केवल speed तक सीमित नहीं रहा, बल्कि society, industry और economy को बदलता चला गया। अब दुनिया एक और बड़े बदलाव की ओर बढ़ रही है — 6G Technology।

यह लेख 6G और 7G से जुड़े हर महत्वपूर्ण पहलू को कवर करता है — global status, India में चल रहे projects, involved companies और future roadmap के साथ।

What is 6G Technology?

6G (Sixth Generation Wireless Technology) अगली पीढ़ी की mobile communication technology है, जिसे 5G के बाद develop किया जा रहा है।
6G का उद्देश्य केवल तेज़ internet देना नहीं है, बल्कि AI-driven, intelligent और ultra-reliable network ecosystem तैयार करना है।

Key Features of 6G Technology

Artificial Intelligence native networks
Terahertz (THz) frequency communication
Ultra-low latency (sub-millisecond)
Integrated sensing and communication
Satellite and non-terrestrial network support
Holographic and immersive communication

Has 6G Launched in Any Country?

Commercial 6G Launch Status

वर्तमान समय (2026) तक दुनिया के किसी भी देश में commercial 6G network officially launch नहीं हुआ है।

6G अभी निम्न चरणों में है:

Research & Development
Laboratory testing
Field trials
Global standardization

Commercial-level public rollout 2030 के आसपास expected माना जा रहा है।

Countries Conducting 6G Trials

हालाँकि commercial launch नहीं हुआ है, लेकिन कुछ देशों में 6G trials और experiments चल रहे हैं:

United Arab Emirates (UAE)
South Korea
Japan
China
European Union nations

ये सभी trials experimental हैं और consumer services के लिए उपलब्ध नहीं हैं।

6G Standards: IMT-2030 and 3GPP

6G technology को globally define करने का काम दो प्रमुख organizations कर रही हैं:

International Telecommunication Union (ITU)

6G को IMT-2030 framework के अंतर्गत develop किया जा रहा है
इसमें performance, latency, reliability और sensing parameters तय किए जा रहे हैं

3GPP (3rd Generation Partnership Project)

Release-20 और Release-21 में 6G specifications तैयार होंगी
यही standards future commercial networks की foundation बनेंगी
