Difference between 3G and 4G

We already know about what is 3G and What is 4G, the basic difference between 3G and 4G is the data transfer and signal quality. So here this article gives information about the difference between 3G and 4G to know more details about it.

Stand for :
  • 3G stands for third generations, 4G stands for fourth generations.
Decades :
  • 3G: 2000.
  • 4G: 2010.
Definition of 3G and 4G :
  • 3G: It is most commonly used for mobile communications standards that allow computers, mobile phones, and other portable electronic devices to access the internet wirelessly.
  • 4G: It is most commonly used for a mobile communication standard intended to replace 3G, allowing wireless internet access at a much higher speed compares to 3G.
Required band :
  • 3G: 1.8 - 2.5 GHz.
  • 4G: 2 - 8 GHz.
Speed :
  • 3G speeds are faster but 4G speed is much faster compared to 3G.
Bandwidth :
  • 3G: 5-20 MHz.
  • 4G: 100 MHz.
Technologies :
  • 3G: Technology is widespread.
  • 4G: Technologies are still on the horizon.
Data transfer rate :
  • 3G : 3.1 Mb/sec.
  • 4G : 100 Mb/sec.
Internet services :
  • In 3G is broadband, 4G is ultra-broadband.
Upload and download speed :
  • 3G Upload speed is - 5 Mbps, 3G Download speed - 100 Mbps.
  • 4G Upload speed is - 500 Mbps, 4G Download speed - 1 Gbps.
Switching method :
  • 3G is a mix of circuit and also have a packet switching network.
  • While 4G is the only packet switching network.
Network architecture :
  • 3G: Wide area network.
  • 4G: Hybrid network.
Mobile TV resolution : 
  • 3G: Low.
  • 4G: High.
Component require for design :
  • 3G: In 3G component require an optimized antenna, multiband different adapters.
  • 4G: In 4G component requires a smarter antenna, wideband radio, and software multi-lane.
IP :
  • 3G : In 3G a number of air link protocol including IP 5.0.
  • 4G: It requires all IP (IP 6.0 ).
Forward error correction :
  • 3G : Turbo codes.
  • 4G : Concatenated codes.
Applications :
  • 3G : CDMA 2000, UMTS, EDGE etc.
  • 4G : WiMAX and LTE advance.
