🔆Evolution of India's networking system
Prime Minister has unveiled a vision document for the rollout of 6G communications technology in India by 2030 titled Bharat 6G.
The vision document has been prepared by the Technology Innovation Group on 6G (TIG-6G) constituted by the Department of Telecommunications (DoT).
📍How mobile network evolve in India
✅1G: Voice calls: 1980s
🔰1G refers to the first generation of wireless cellular technology and they enabled communication between two supported devices using a wireless network.
🔰Based on the analog system, 1G supported only voice calls, and those too of poor quality because of interference and it worked in a fixed area because of a lack of roaming support by the network.
✅2G: Telephony services:
The analog system was now replaced by a much more advanced digital technology for wireless transmission called the Global System for Mobile communication (GSM).
🔰With digital underpinning, the 2G supported better quality voice calls and data services such as short message service (SMS) and multimedia messaging service (MMS).
🔰Besides, this mobile network enabled roaming facility, allowing users to attend calls, and send and receive texts and multimedia content on the go.
✅3G: Age of applications:
🔰The third generation mobile network introduced high speed internet services, which set the stage for smartphones and application ecosystems.
🔰While 3G enabled the concept of mobile television, online radio services, and emails on phones, it is video calling and mobile phone apps that really define the 3G era.
✅4G: Internet calling:
3G set the base for 4G, which is the current generation of the mobile network.
🔰The concepts introduced by 3G such as high definition voice calls, video calls, and other internet services become a reality in 4G.on account of a higher data rate and advanced multimedia services that the mobile network supports.
✅It perfected the LTE (Long Term Evolution) system, which significantly improves data rate and allows simultaneous transmission of voice and data.
🔰Internet calling, or VoLTE (Voice over LTE), is one of the many advantages of the 4G mobile network.
✅5G : IoT and enterprises:
🔰The low latency and high throughput make the network ideal for enterprise use, especially with regard to automation and connected ecosystem.
🔰The 5G network will operate in the millimeter-wave spectrum (30-300 GHz) which can send large amounts of data at very high speeds as the frequency is very high, and it experiences little interference from surrounding signals.
✅6G : Connected ecosystem:
🔰6G is touted to drive the adoption of 5G use cases at scale through optimisations and cost reduction, especially at the enterprise level.
🔰India is looking at 2023end or early 2024 to launch 6G services using indigenous developed infrastructure.
