What is the mobile communications generation? What are the differences between 1G, 2G, 3G, 4G and 5G?
Very few people often do not know about “G” but they also use it in their cell phones, have you ever wondered what the letter “g” means in 1g, 2g, 3g, 4g, 5g ...? G stands for “generation” which is called “generation” , for example 1g means first generation, while 2g means second generation, in this all these numbers represent only one. There are different standards for telephone networks in each generation, which describe changes in their features for a particular mobile phone system .
Since 1980 there has been development of one network generation per decade approximately, which covers a total of 4 decades ( 1G, 2G, 3G, 4G ) and now the 5G network is expected to be launched soon in 2021. In 1980, this journey started with 1G ( first generation ), while with the passage of time there have been many changes such as the second generation, 2.5G, the 3G, the fourth generation , but all of them have improved with the change and now continue until 5G .
Nowadays, as you know, we all use 4G wireless communication technology in our mobile phones. Now let's see where this generation of wireless networks from 1G to 4G started.
1g 2g 3g 4g 5g speed
- 1G - speed up to 2.4 Kbps.
- 2G (GSM) - speeds of up to 64 kbps.
- 2.5G and 2.75G - from 144 kbps to 384 kbps.
- 3G - Provides speeds from 144 Kbps to 2 Mbps.
- 4G ( LTE ) - Provides speeds from 100Mbps to 1Gbps.
- 5G - Speeds up to 10 Gbps probably.
1G - Voice call
Very few people know about 1G generation, it is the oldest cellular network system , which was the first mobile network generation started with 1G (first generation). The first generation AP is a wireless communication technology, and it was launched in the year 1980. The 1G network is the first generation of wireless mobile communication, and it is used to operate on the analog signal to transmit data.
There were many limitations to the first generation mobile network , but they started because they made it possible to " communicate " with each other for the first time. From this mobile network, only calls could be made, there were no other features. In this, only one person can communicate from person to person for a limited distance. Its internet speed was 2.4 kbps, and it was a new technology for this generation, so these cell phones were also very expensive at the time.
Some of the main features of 1G:
- It was the first 1G wireless communication technology
- 1g internet speed was up to 2.4 kbps
- A first-generation cellular network operating on an analog signal
- It was launched AMPS (Advanced) mobile phone service or phone analog signal for the first time in the United States in the mobile phone system 1G
1 gram defect:
- The sound quality was not good
- Phone battery life was limited
- 1g cell phone volume was big
- There is no secure data in this generation network.
- The quality of first generation mobile phones was poor and not portable either.
2G - SMS and MMS
The full form of 2G is called " second generation " and in Hindi " second generation ". 2G technology is the first digital cellular network, which was more secure than 1G with better voice quality. 2G is the second generation of mobile phone networks , which uses digital signals for the first time. It was launched in Finland in 1991, where GSM technology was used . The data transfer speed of the 2G network was up to 64 kbps.
2G network phone technology has provided calls as well as internet data services such as text messaging, picture messaging and picture messaging, but 2G has not yet succeeded in terms of video calls, video conferencing, mobile TV and multimedia services.
Some of the main features of 2G network:
- 2G network was first launched in Finland in 1991.
- 2G networks use digital signals instead of analog
- The internet data speed was more than 64 kbps.
- In the second generation, multimedia services such as SMS, MMS and Picture SMS were available
- Provide high quality voice calls above 1G
- 2G technology was the second generation based on GSM / CDMA
2g defect:
- The 2G network phone's digital signal was not strong, due to calls dropping while talking.
- Can't play big data like videos from this 2G network
- There was a signal problem in the 2g mobile network if there was no good network coverage in a certain area.
2.5g and 2.75g networks
After a few years of 2G technology, the new version of 2.5G and 2.75G mobile network technology appeared, which brought some improvement in the speed of Internet data services ( GPRS and EDGE) . 2.5g began to be used for Internet communication services such as Wireless Application Protocol , Multimedia Messaging Service (MMS), e-mail, and access to the World Wide Web.
With 2.5G or GPRS (General Packet Radio Service), the data throughput was around 48kbps to 120kbps and 2.75Gbps based on EDGE (Enhanced Data GSM Environment) according to its theory is 384kbps second (actually 100 kbps). kilobits per second). 2.75G data connection or EDGE Internet speeds are faster than GPRS (2G and 2.5G) connections , but are generally slower than 3G networks.
Main Features of 2.5G and 2.75G:
- Make phone calls easily
- Emails can be sent and received
- Can access web browsing
- Internet speed: 64 - 144 kbps to 384 kbps
- The mobile has camera features
- It only took 6-7 times to download an mp3 song
3G - mobile data, video calls and high speed
The third generation technology is called the " third generation" of wireless mobile network . It was developed in 2001. The design of 3G technology specifically for mobile phones and multimedia that are usually called "smart phones". High-speed bandwidth and data transfer speeds in 3G networks have increased from 144 Kbps to 2.05 Mbps compared to the previous 2G, allowing simultaneous phone calls, Internet access , e-mail exchange and easy messaging.
In the third generation, new features were introduced in the audio and video codecs, providing better audio communication quality. Video calling, TV streaming, 3D gaming, large file transfer, multimedia applications, YouTube , high data speed and many other features were launched in 3G. Only after the arrival of 3G did companies also start new data plans. Remember this, the camera with which we take a selfie from the phone is the same third generation because of the front camera. The 3G network is also known as IMT-2000.
Some of the main features of the 3G network:
