What is the Difference between 3G and 4G Networking? - Technology Times


Well, first of all both the technologies are wireless technologies.  It is much clear from the numeric part that the 3G has emerged before than the 4G technology.  Here, G stands for generation.  As we know that every new generation comes with the advancement and the upgraded features.  Similarly, 4G dominates the 3G technology in terms of excessive high speed data transmission.  In 4G we use specially designed highly conductive devices for the transmission which we were unable to use in the 3G technology. It is significant that 3GPP has played a main role in the evolution of generations in the mobile networks and it is a collaboration of telecom associations from various countries and regions of the world aiming at providing a globally applicable 3G standards based on GSM systems.

What is a 3G networking?
The 3G that is third generation technology of the mobile networks that is aiming to the high speed data exchange/transmission and providing applications like video conferencing, streaming and the list is long.  They came with two calibrations namely 3GPP and 3GPP2.  As per the International Telecommunication Union (ITU) the following requirements must be met by any network to be termed as 3G networks.

  1. Downlink rate of 144 Kbps for mobile handsets and 384 Kbps for pedestrian traffic. 
  2. 2 Mbps indoor downlink speed.
  3. On demand bandwidth and 2 Mbps internet access.


What is a 4G networking?
This is the latest and the fastest mobile networking communication.  It is predecessor of 3G networks.  It works as about 100 Mbps in high mobile environments and about 1Gbps in stationary environments.  This amount of data is really a big mass of data and it seems like that the file you just received was already present in your hard drive.  Startling, but true; 4G is the ultimate of them all.  In this Wi-Max that is Worldwide interoperability for Microwave Access and the long term evolution (LTE) are the technologies that are considered. Following specifications need to be met by any network to be considered as 4G:

  1. 100Mbps data rate in high mobile environments and 1Gbps in stationary environments
  2. Network operate on IP packets (All IP network)
  3. Dynamic channel allocation with channel bandwidth being varying from 5MHz to 20 MHz as required by the application
  4. Soft hand over capability.


 Henceforth, these are the differences that differentiate between both of the networks.
