What is 2G, 3G? and 4G? and What is Difference between 2G 3G 4G Network Bands. What is the difference between 2G 3G 4G mobile networks? 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services in the country. A higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network.

Understanding the mobile networks :

As the name would suggest, 1G was the first generation of mobile networks. Here basically, radio signals were transmitted in ‘Analogue’ form and expectedly, one was not able to do much other than sending text messaging and making calls. But the biggest disadvantage, however came in the form of limited network availability, as in the network was available only within the country.

2G, first introduced in 1992, is the second-generation of cellular telephone technology and the first to use digital encryption of conversations. 2G networks were the first to offer data services and SMS text messaging, but their data transfer rates are lower than those of their successors.

Between 2G and 3G there was a short phase in between where mobile phones became sleeker and more ‘pocketable’ if we can call it that.  This is popularly referred to as 2.5G where the quantity of radio waves to be transmitted was much lower. This in turn had an effect on the shape and structure of mobile phones. But most of all, 2.5G helped in the ushering of GPRS (General Pocket Radio Service).

3G networks succeed 2G ones, offering faster data transfer rates and are the first to enable video calls. This makes them especially suitable for use in modern smartphones, which require constant high-speed internet connection for many of their applications.

4G is the fourth generation of mobile phone communications standards. It is a successor of the 3G and provides ultra-broadband internet access for mobile devices. The high data transfer rates make 4G networks suitable for use in USB wireless modems for laptops and even home internet access.
