4G technology is the fourth generation of wireless technology available from mobile service providers. This technology, also sometimes called "ultra mobile broadband," is designed to provide greater data transfer rates and more secure connections. Various wireless devices can take advantage of 4G technology, including phones and tablets. There is some controversy over the use of "4G," however, since some early adopters did not meet the requirements of the technological standard.
Purpose of 4G
Ultra mobile broadband refers to faster rates of data transmission available on a wireless network. 4G technology may provide data transmission rates between 100 megabits per second (Mbps) and one gigabit per second (Gbps). By comparison, 3G or third-generation networks offer data transmission speeds averaging around 200 kilobits per second (kbps), which is significantly slower than those that 4G technology makes possible.
What is the difference between 2G, 3G, 4G, mobile networks?
G in 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 networks on the other hand, were based on narrow band digital networks. Signals were transmitted in the digital format and this dramatically improved the quality of calls and also reduced the complexity of data transmission. The other advantage of the 2G network came in the form of Semi Global Roaming System, which enabled the connectivity all over the world.
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).
The 3rd generation of mobile networks has become popular largely thanks to the ability of users to access the Internet over devices like mobiles and tablets. The speed of data transmission on a 3G network ranges between 384KBPS to 2MBPS. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 3G is the best option for users who need to always stay connected to Internet.
4th Generation mobile networks are believed to provide many value added features. In addition to all the 3G facilities, data transmission is believed to go through the roof with speeds ranging between 100MBPs to 1GBPS. Phew! Happy talking, surfing, conferencing, chatting, networking, partying, or whatever you want to do on your mobile phone.
