December 5, 20113G is network standard that allows users to transmit
voice and data.
4G is the next
evolution in wireless communication, allowing download speeds of 3-6 Mbps and upload speeds of up to 1 Mbps, 4G is designed especially for data transmission rather than voice, so 4G offers faster access to data using mobile phones

December 5, 2011Theoretically they are classifications of technologies set by the ITU-R.
However in general they are used to refer to third generation “3G” technologies currently available and fourth generation “4G” technologies currently being implemented or upcoming.
A lot of technologies overlap into both generations which makes this classification somewhat inaccurate. This is why most manufacturers state the actual supported technologies and protocols within a phones specification.
The LTE standard for example is considered being 3.9G because in it’s current development state it doesn’t match all requirements set by the ITU-R for the 4G classification yet the technology itself can [and probably will] be part of the fourth generation.
