3G and 4G both have become very common and talked about terms among the owners of smart phones. However, most of the people do not understand the exact relevance of these terms but associate these with the goodness of a network and transmission speed of data in their phone.
3G and 4G both are standards that standardize the mobile phone communication and spell out how & with what speed do airwaves operate in order to transmit the information, that is, data and voice. Initially when 3G was introduced it was considered as a significant improvement over the existing 2G network. After 3G, 4G network was introduced in which the technical specifications like transmission speed, data throughput, upload & download rate, network architecture and switching techniques got significantly improved and speed in most of the aspects got enhanced.
The major advancement that was witnessed from 3G networks to 4G networks was the usage of message switching along with packet switching for transferring information. The network architecture in 4G was also significantly improvised to support the higher communication speeds. here is the info graphic that outlines the exact technical specifications oriented differences between these two new age technologies.
