2G (second generation) and 3g (third generation) are two types of wireless phone technology. The number before G shows the power and speed of the technology. The main difference between 2G and 3g is that 3G offers faster data speed compared to 2G, however, there is not much significant difference between these two network technologies in the case of voice and text messaging usage.
What is 2G?
2G stands for second generation wireless phone technology that was launched in 1991 on the Global System for Mobile Communications (GSM). In 2G, three new features were introduced that were more advanced compared to its predecessor. These three features were: mobile conversations were digitally encrypted; 2G systems were more effective and efficient at higher levels of mobile phone penetration; and third, it introduced mobile data services including SMS text messages for the first time. With the introduction of 2G, several other mobile services emerged including text messages (SMS), picture messages and multimedia messages (MMS).
What is 3G?
3G stands for third-generation wireless phone technology that was first introduced to the public in 1998. This technology is based on established standards for mobile telephony. Through this technology you can have coverage of text messages, voice calls and also provide fast access to the Internet. It has the capacity to transport a larger amount of data. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. It is a new generation of cellular standards after 1G and 2G. The mobiles that are used for this are called “Smartphones”. This technology cannot be used in mobile phones made for 1G and 2G. This paved the way for a new mode of communication, 3G-enabled video calling.
- 3G offers faster data speed compared to 2G, however, there is not much significant difference between these two network technologies in the case of voice and text messaging usage.
- The 3G network license fee is more expensive as compared to 2G networks.
- 3G network system development is more complicated and expensive than 2G networks.
- Smartphones by default use 3G network technology, while 2G networks are mostly less compatible with smartphones.
- 2G network technology is mainly used to share information through voice signals or messaging, while in 3G, data can be transferred at higher speeds through video conferencing, MMS and many more.
- Download and upload speeds in 2G are restricted up to 236 Kbps. In case of 3g network technology, upload speed is available up to 5.7 Mbps while download speed is available up to 21 Mbps.
- 2G networks are: GSM, CDMAOne and D-AMPS. 3G networks are: UMTSA FDD and TDD, IMT-2000 DECT, CDMA2000 1x EVSO, CDMA200 3x, TD-SCDMA, EDGE, Arib WCDMA.
