The 2G network or 2g technology brought a big change in the world of mobile phones. After 1G, the 2G network gave a new look to the communication facilities, got a big shift in network communication, and solved the problem of connectivity. in this post you will learn all about what is 2g technology
Many facilities were added to the 2G network, like text message data transmission and better network coverage. 2G network provided the facility of text messaging. Now, people cannot only make calls but can also send small text messages and convey their message from one place to another. It worked like a letter. The letter that was sent instantly from one place to another was called SMS, which was possible through 2G. Similarly, data transmission was also achieved. The network started data transmission, which made services like internet browsing and sending emails possible. Although problems like slow speed were faced in the 2G network, it was still a big step in the world of communication and connectivity. 2G took the first initiative in this. In the beginning, we could connect to internet connectivity and use other browsers to get information about different things. This was also a big step in the world of connectivity, which was made possible by 2G.
When 2G Launched In India
2G(Second generation) technology was first introduced in 1990 and first used 2g network in 1995 in india
2G Network Initiative:
- GSM
The 2G network was developed in the early 1990s. It has two main standards. 1. GSM Global System Mobile Communication was developed in Europe and used all over the world. GSM established a standard for calls and text messaging. This was the second major step after 1G, which connected us with the technology of communication.
- CDMA.
The second major standard of the 2G network was CDMA Division Multiple Access technology, which became popular in America and other countries. In this, different users were separated through codes on the same frequency. This technology was also a part of the 2G network, and along with that, a data transmission facility was also available. This was a big step after 1G, which was able to connect people in a better way. Sending SMS from one place to another without any interruption, making voice calls, and using internet browsing are all services that are available through 2G technology.
Better network coverage With 2G technology, we got much better services than 1G, which were available for voice calls, internet browsing, and SMS. Security also improved due to the use of digital signals. Encryption technology was used in the 2G network, which made the call and data transmission more secure. Better network coverage as compared to 1G. It started providing network signals even in small towns and rural areas, which increased the facility of telecommunication. For example, with the help of SMS, small messages of up to 160 characters could be sent. SMS makes communication fast and easy, and it has become a popular method that people have started using a lot. The 2G network was an important turning point in the world of communication. This network came in the 1990s, and with it, many new facilities and improvements were made, which impressed people a lot. There were many changes in 2G as compared to 1G, due to which all the problems faced by people in 1G were improved in 2G.
