Difference Between 3G and 4G

3G Vs 4G

3G is one of the fastest ways of connecting your mobile device to the Internet. 3G stands for 3rd generation, named so because of the evolution of speeds offered by the mobile phone carriers. 3G has been around for quite some time now. 4G is the next generation of mobile phone data connectivity. 4G stands for 4th generation. 4G is the new standard being developed to phase out 3G and make high speed Internet more accessible.


One of the prime differences between 3G and 4G is the underlying technology and the spectrum that it uses to transfer data over the air. WCDMA, HSPA are two of the most common technologies that are used for 3G communications. Mobile phone carriers have named WiMax, LTE and allied technology as 4G technology. Although the 4G standards have not yet been completely decided and implemented. The framework to implement it is in its place.

Connection Speed

The speed of 4G connections is greater than 3G. The current speed of a 3G connection is around 12Mbps download and 6Mbps upload. 4G connections have been planned in a way to implement speeds of over 100Mbps. Only wireless LAN connections have been able to provide such speeds to the consumers till now.

Key Differences between 4G and 3G

  • 3G network is already available in many countries and the spectrum for its usage has been allocated unlike 4G
  • 3G is widely in use today and 4G is still an emerging standard
  • 4G is the next generation data connectivity
  • 4G is much faster than 3G
  • 4G uses packet switching that is more efficient and fast than the circuit switching 3G technology
  • 4G does not have a specific standard associated with it. You can call WiMax and LTE to be technologies associated with 4G

4G promises to allow users to make video calls and VoIP calls without any delays and latency errors. With a high speed connection, streaming of videos over the mobile phone network and value added services like mobile television becomes a possibility. Mobile phone service providers are looking at ways to leverage this new technology so that it becomes both useful and profitable.

Circuit Switching

Circuit switching is another key change in 4G; this technology does away with circuit switching and uses a hybrid of circuit switching and packet switching. Telephone systems have been using this system for a long time now. The only disadvantage of this technology is that the resource is occupied till the connection exists. Packet switching is very much prevalent in the computer networking domain and if used effectively can be used in an efficient manner for mobile phone data connectivity and 4G hopes to achieve this. You will now be able to make voice calls and video calls over your 4G network without any latency and delays.
