India's Telecom Evolution: 1G to 6G - A Technological Journey
Imagine your phone's speed getting a major upgrade every few years!
First came 1G, just for calls.
Then 2G brought text messages.
3G let you browse the web and video call.
4G made everything much faster, like a super speedy computer in your hand.
Now, 5G is even faster, helping lots of devices connect.
India is working on 6G which will be lightning fast and ready by 2030.
6G will allow technologies like self-driven cars.
India has entered the league of countries manufacturing their own telecom equipment with the launch of BSNL's 'Swadeshi' 4G stack.
1G, introduced in the late 1970s, offered voice calls with low sound quality, while 2G introduced digital signals and data services like SMS and MMS.
3G brought mobile internet, emails, and video calling around 2001, with speeds four times faster than 2G.
4G, around 2010, provided high-speed data, making phones more like handheld computers.
India plans to launch 6G services by 2030, promising speeds up to 100 times faster than 5G.
